−# Scope {toc}

−

−## This standard covers the furnishing and installation of factory-fabricated toilet compartments and urinal screens for commercial and institutional restrooms. {note}

−## A toilet compartment is an assembly of doors, pilasters (the vertical support posts), and panels (the dividing walls), together with the brackets and hardware that connect them and anchor them to the building structure. {note}

−## The scope includes the selection of compartment material for the service environment, the selection of a mounting style appropriate to the structure and ceiling condition, the hardware that governs durability and privacy, and the dimensional and operational requirements for accessible compartments. {note}

−## This standard establishes the material, fabrication, hardware, accessibility, and installation requirements for those compartments. {note}

−

−## Toilet compartments are a finish item subject to constant moisture, repeated impact, and deliberate abuse, and the correct material selection is the single most consequential decision in this standard. {note}

−## A compartment material that performs well in a low-traffic office restroom will fail prematurely in a school, a stadium, or a correctional environment. {note}

−## The narrative throughout this standard ties each material to the occupancy and service conditions in which it is the appropriate choice, so that the specifier selects the material from the actual service environment rather than from first cost alone. {note}

−

−## Coordinate this work with [[sync/toilet-accessories]] for grab bars, dispensers, and receptacles that mount on or adjacent to compartments; with [[sync/plumbing-fixtures]] for the water closets and urinals the compartments enclose; with [[sync/gypsum-board-assemblies]] and [[sync/unit-masonry]] for in-wall blocking and anchorage backing; and with the finished flooring and base trades for floor anchorage conditions. {note}

−

−## Compartment layout, the number and size of compartments, and the location of accessible compartments shall be [[drawing: as indicated on the restroom plans and interior elevations]].

−

−### Compartments, pilasters, doors, and hardware within a single restroom shall be the product of a single manufacturer to ensure dimensional and finish compatibility.

−

−## Single-Source Responsibility {toc}

−

−### The compartment material and the hardware that fastens to it must be matched; door hardware preparations, bracket spacing, and edge construction are specific to each manufacturer's panel system.

−

−```datasheet

−label: Single-Source Responsibility

−type: radio

−options:

− - "All compartments, screens, and hardware from a single manufacturer"

− - "Compartments and accessories furnished as a coordinated package by a single supplier"

−default: "All compartments, screens, and hardware from a single manufacturer"

−```

−

−### Mixing pilasters from one manufacturer with doors or hardware from another voids the fit of factory-machined hardware preparations and shall not be permitted.

−

−## Field Measurements {toc}

−

−### Compartment dimensions, and in particular the clear dimensions of accessible compartments, depend on the actual as-built location of plumbing fixtures, walls, and floor drains. {note}

−

−### The Contractor shall verify field dimensions of each restroom before fabrication.

−### Where field conditions differ from the contract drawings such that an accessible compartment cannot achieve its required clear dimensions, the Contractor shall notify the Architect before fabrication.

−

−# Service Conditions and Material Selection {toc}

−

−## Moisture, Humidity, and Abuse Classification {toc}

−

−### The following classification governs the material selection that follows; it is not a substitute for the specifier's knowledge of the occupancy, but it frames the decision. {note}

−

−### The compartment material shall be selected for the moisture exposure, humidity, traffic, and abuse anticipated at the specific restroom.

−

−```datasheet

−label: Restroom Service Condition

−type: select

−options:

− - "Standard commercial — office, retail, moderate traffic, dry"

− - "High-traffic public — schools, stadiums, transit, airports"

− - "Wet / high-humidity — pool, locker room, gang shower, hose-down cleaning"

− - "Healthcare / hygienic — hospitals, clinics, food service"

− - "High-abuse / vandal-prone — corrections, parks, unsupervised public"

−default: "Standard commercial — office, retail, moderate traffic, dry"

−```

−

−## Material Selection by Occupancy {toc}

−

−### High-pressure decorative laminate (HPL) and powder-coated steel are economical and appropriate for standard, dry commercial restrooms with supervised traffic, and HPL is the most common selection in that environment. {note}

−### Solid plastic (HDPE) and solid phenolic core are the durable choices for high-traffic public, wet, and abuse-prone environments because both materials are unaffected by moisture, will not delaminate or swell, and resist graffiti and impact; solid plastic is the default for schools, stadiums, and pool or locker-room applications, and solid phenolic is preferred where the highest resistance to vandalism and hose-down cleaning is required. {note}

−### Stainless steel is appropriate for healthcare, food service, and high-design applications where cleanability and corrosion resistance are priorities and the budget supports it. {note}

−

−### Material selection should follow the service condition.

−### Powder-coated steel shall not be specified for wet or hose-down environments, because moisture penetrating a chip or scratch in the finish will corrode the steel substrate from within.

−

−# Compartment Materials {toc}

−

−## High-Pressure Decorative Laminate (HPL) {toc}

−

−### High-pressure decorative laminate compartments consist of a decorative laminate face conforming to NEMA LD 3 bonded under heat and pressure to a moisture-resistant particleboard core, with the edges sealed and banded. {note}

−### HPL provides a wide range of colors and patterns at moderate cost and is the standard selection for dry commercial restrooms. {note}

−

−### The HPL core substrate shall be specified, using a marine-grade or exterior-rated substrate where elevated moisture exposure is expected.

−

−```datasheet

−label: HPL Core

−type: radio

−options:

− - "Moisture-resistant particleboard core (standard interior)"

− - "Marine-grade / exterior-rated substrate (elevated moisture)"

−default: "Moisture-resistant particleboard core (standard interior)"

−```

−

−### The thickness of HPL panels and doors shall be specified for the project's compartments.

−

−```datasheet

−label: HPL Panel and Door Thickness

−type: radio

−unit: in

−options:

− - "3/4 in"

− - "1 in"

−default: "1 in"

−```

−

−### HPL shall not be used in wet, high-humidity, or hose-down environments, because moisture reaching the particleboard core through a damaged edge causes the core to swell and the laminate to delaminate.

−

−## Solid Plastic (HDPE Polymer) {toc}

−

−### Solid plastic compartments are fabricated from a single homogeneous sheet of high-density polyethylene (HDPE) polymer, color throughout, with no laminate face and no internal core to delaminate or absorb water. {note}

−### Solid plastic is impervious to moisture, resists graffiti (most marker and paint can be cleaned or sanded off because the color runs through the full thickness), resists impact, and does not support mildew growth. {note}

−### Solid plastic is the default material for high-traffic public restrooms, schools, stadiums, and wet environments. {note}

−

−### The thickness of solid plastic (HDPE) panels and doors shall be specified for the project's compartments.

−

−```datasheet

−label: Solid Plastic Panel and Door Thickness

−type: radio

−unit: in

−options:

− - "3/4 in"

− - "1 in"

−default: "1 in"

−```

−

−```datasheet

−label: Solid Plastic Fire Test Documentation

−type: radio

−options:

− - "NFPA 286 room-corner test report provided (plastic interior finish)"

− - "Class B flame-spread per ASTM E84 (where AHJ accepts for the occupancy)"

−default: "NFPA 286 room-corner test report provided (plastic interior finish)"

−```

−

−### Because HDPE is a plastic interior finish, it shall be tested for fire performance under NFPA 286 where the building code requires room-corner testing of plastic interior finishes, rather than relying on ASTM E84 alone.

−

−## Solid Phenolic Core {toc}

−

−### Solid phenolic core compartments are fabricated from layers of phenolic-resin-impregnated kraft paper fused under heat and pressure with a decorative or solid-color face and a dark (typically black) core, producing a dense, homogeneous panel that is thinner and stronger than HDPE at equivalent stiffness. {note}

−### Solid phenolic is impervious to moisture, withstands hose-down cleaning and high humidity, and offers the highest resistance to impact and vandalism of the common materials. {note}

−### It is the preferred selection for correctional facilities, heavy-use stadiums and transit restrooms, and gang showers and pool environments where the highest durability is required. {note}

−

−### The thickness of solid phenolic panels and doors shall be specified for the project's compartments.

−

−```datasheet

−label: Solid Phenolic Panel and Door Thickness

−type: radio

−unit: in

−options:

− - "1/2 in"

− - "3/4 in"

− - "1 in"

−default: "3/4 in"

−```

−

−### The thickness of solid phenolic pilasters shall be specified for the project's compartments.

−

−```datasheet

−label: Solid Phenolic Pilaster Thickness

−type: radio

−unit: in

−options:

− - "3/4 in"

− - "1 in"

−default: "1 in"

−```

−

−## Powder-Coated Steel {toc}

−

−### Powder-coated steel compartments consist of two formed sheets of galvannealed steel (conforming to ASTM A653) over a honeycomb core, with a baked-on powder-coat enamel finish electrostatically applied. {note}

−### Powder-coated steel is the most economical material and is appropriate for dry, standard commercial restrooms. {note}

−

−### The gauge of the powder-coated steel face sheets shall be specified, using a heavier-duty gauge where increased impact resistance is required.

−

−```datasheet

−label: Powder-Coated Steel Face Sheet Gauge

−type: radio

−options:

− - "22 gauge face sheets (standard)"

− - "20 gauge face sheets (heavier duty)"

−default: "22 gauge face sheets (standard)"

−```

−

−### Powder-coated steel shall not be used in wet, high-humidity, or hose-down environments; the galvannealed substrate corrodes wherever moisture reaches the steel through a chip, scratch, or unsealed edge.

−

−## Stainless Steel {toc}

−

−### Stainless steel compartments consist of formed stainless steel sheets (Type 304 conforming to ASTM A666 or ASTM A240, or Type 316 where higher corrosion resistance is required) over a honeycomb core. {note}

−### Stainless steel is corrosion-resistant, cleanable, and appropriate for healthcare, food service, and high-design applications. {note}

−

−### The stainless steel type shall be specified, using Type 316 where the compartment is exposed to coastal, chemical, or high-chloride conditions.

−

−```datasheet

−label: Stainless Steel Type

−type: radio

−options:

− - "Type 304 — standard corrosion resistance"

− - "Type 316 — elevated corrosion resistance (coastal, chemical, high-chloride)"

−default: "Type 304 — standard corrosion resistance"

−```

−

−```datasheet

−label: Stainless Steel Finish

−type: select

−options:

− - "No. 4 satin (directional brushed)"

− - "Textured / patterned (vandal-resistant, hides scratches)"

− - "No. 8 mirror (high-design, low-abuse only)"

−default: "No. 4 satin (directional brushed)"

−```

−

−### A textured or patterned finish should be specified in vandal-prone applications because a satin or mirror finish shows scratches and graffiti more readily than a textured finish.

−

−## Compartment Material Selection {toc}

−

−### This is the governing material decision for the standard. {note}

−### Set the default to the most common procurable choice for the project's predominant restroom type and override per restroom on the shop drawings where conditions differ. {note}

−

−### The compartment material shall be selected from the service condition and confirmed per restroom on the shop drawings where conditions differ.

−```

−

−# Mounting Styles {toc}

−

−## The mounting style determines how the pilasters transfer load to the structure and how the compartment is braced against lateral force. {note}

−## The choice depends on the ceiling type and height, the floor construction, and the available overhead structure. {note}

−

−## Mounting style shall be selected per restroom and confirmed against the reflected ceiling plan and the structural conditions above the ceiling.

−

−```

−

−## Headrail shall be continuous anti-grip extruded aluminum at all overhead-braced installations.

−

−## Pilaster floor anchorage shall be concealed by a stainless steel pilaster shoe at floor-anchored and floor-to-ceiling installations.

−

−## Floor-Anchored / Overhead-Braced {toc}

−

−### In the floor-anchored / overhead-braced style, pilasters are anchored to the floor and stabilized at the top by a continuous anti-grip aluminum headrail spanning the tops of the pilasters and anchored to the side walls. {note}

−### This is the most common and most economical mounting style and is the appropriate default for the large majority of commercial and institutional restrooms. {note}

−### It tolerates a wide range of ceiling heights and does not require overhead structure for support. {note}

−

−### The headrail shall be a continuous extruded aluminum profile conforming to ASTM B221 with an anti-grip (sloped or rounded) top to discourage hanging weight from the rail.

−

−## Floor-to-Ceiling {toc}

−

−### In the floor-to-ceiling style, pilasters are anchored to both the floor and overhead structure, producing the most rigid and abuse-resistant installation. {note}

−### It is preferred for high-abuse, correctional, and heavy-use public applications, and where the design intent is a full-height appearance. {note}

−

−### Floor-to-ceiling mounting requires structural support above the ceiling at each pilaster; the Contractor shall coordinate overhead blocking or structure before fabrication.

−

−## Ceiling-Hung {toc}

−

−### In the ceiling-hung style, pilasters are suspended from overhead structure with no floor contact, leaving the floor clear beneath the compartments for ease of cleaning. {note}

−### It is favored in healthcare and high-cleanliness applications because the open floor simplifies wet cleaning. {note}

−

−### Ceiling-hung mounting requires substantial concealed structural support above the ceiling at each pilaster and shall be used only where that structure is provided and coordinated.

−

−## Floor-Mounted {toc}

−

−### In the floor-mounted style, pilasters are anchored to the floor only, with no overhead headrail or ceiling attachment. {note}

−### It is limited to short pilaster runs and low-abuse applications where lateral bracing from a headrail is not required. {note}

−

−### Floor-mounted compartments are less rigid than the other styles and shall not be used for high-traffic or abuse-prone restrooms.

−

−## Pilaster Shoe {toc}

−## Hardware is the determinant of long-term durability and privacy performance. {note}

−

−## Hardware exposed to abuse — hinges, latches, and brackets — shall be of a material and grade matched to the compartment's service condition.

−

−## Through-bolted fasteners with tamper-resistant heads should be specified in vandal-prone applications.

−

−## Brackets {toc}

−

−### Stirrup (two-ear) brackets are the standard for commercial applications. {note}

−

−### Full-height continuous brackets shall be specified for high-abuse, correctional, and heavy-traffic applications because they distribute load over the full height of the connection and resist prying and impact far better than point brackets.

−## Hinges {toc}

−

−### Gravity (cam) hinges are the standard for commercial compartments; they allow the door to be set to rest in a partially open position when unoccupied (a visual cue that the compartment is vacant) and to close gently. {note}

−

−### The hinge type shall be specified for each compartment, selected for the application's cycle frequency, abuse exposure, and self-closing requirements.

−```

−

−### Continuous (piano) hinges shall be specified for high-cycle and abuse-prone applications (schools, stadiums, corrections) because they carry the door load along its full height, eliminate the pinch and pry points of point hinges, and greatly outlast cam hinges in high-traffic service.

−### Accessible compartment doors shall be self-closing per the accessibility requirements below, and the hinge selected for an accessible compartment shall provide reliable self-closing.

+title: Toilet Compartments

+category: Architectural / Specialties

+description: >

+ When to use: Factory-fabricated toilet compartments, urinal screens, and dressing screens for commercial, institutional, educational, healthcare, transit, assembly, and correctional restrooms. Covers panel material families including plastic-laminate-faced, solid plastic HDPE, solid phenolic core, powder-coated steel, and stainless steel; panel, door, and pilaster thickness; interior-finish fire performance; mounting styles including floor-anchored and overhead-braced, floor-to-ceiling, ceiling-hung, and floor-anchored without headrail; headrails, pilaster shoes, brackets, hinges, latches, coat hooks, and fasteners; compartment dimensions, panel height, floor clearance, and sightline treatment; and wheelchair accessible and ambulatory accessible compartments under the 2010 ADA Standards and ICC A117.1.

+ Not intended for: Grab bars, dispensers, mirrors, shelves, and waste receptacles mounted in or adjacent to compartments (see [[sync/toilet-accessories]]); water closets, urinals, flush valves, and fixture carriers (see [[sync/plumbing-fixtures]]); shower and bathing compartments furnished as part of a bathing-fixture assembly; cubicle and privacy curtains; demountable office partitions; operable and folding partitions; metal lockers and locker-room benches (see [[sync/metal-lockers]]); site and park restroom buildings furnished as packaged structures.

+---

+# Scope {toc}

+## This standard covers the furnishing and installation of factory-fabricated toilet compartments, urinal screens, and dressing screens, including panels, doors, pilasters, headrails, brackets, hardware, and the anchorage that ties them to the building structure. {note}

+## A toilet compartment is an assembly of three part families: pilasters, which are the vertical posts that carry load to the floor or to overhead structure; panels, which are the dividing walls between compartments and along the back; and doors, which hang from the pilasters on hinges and close against a strike. {note}

+## The following are outside the scope of this standard: {note}

+- Grab bars, paper and seat-cover dispensers, mirrors, shelves, and waste receptacles, which are covered by [[sync/toilet-accessories]] even where they mount to a compartment panel

+- Water closets, urinals, flush valves, and fixture carriers, which are covered by [[sync/plumbing-fixtures]]

+- Shower and bathing compartments furnished as part of a bathing-fixture assembly, and the curtains and rods serving them

+- Demountable office partitions, operable partitions, and folding partitions

+- Metal lockers, locker-room benches, and their anchorage, which are covered by [[sync/metal-lockers]]

+- In-wall blocking and anchorage backing, which are furnished by the wall trades under [[sync/gypsum-board-assemblies]] and [[sync/unit-masonry]]

+## Four decisions in this standard are independent of one another and are made separately: the panel material, the mounting style, the hardware package, and the privacy configuration of panel height, floor clearance, and sightline treatment. {note}

+## A material that survives one restroom fails in another for reasons that have nothing to do with quality of manufacture, so this standard states what each material does under moisture, impact, and cleaning chemistry rather than ranking the materials against one another. {note}

+## The compartment layout, the number and width of compartments at each restroom, and the location of every accessible compartment shall be [[drawing: as indicated on the restroom plans and interior elevations]].

+## The Contractor shall coordinate in-wall blocking and anchorage backing with the wall trades before the walls are closed in.

+# Referenced Standards {toc}

+## Materials, fabrication, finish, hardware, and installation shall comply with the latest adopted edition of each of the following unless a specific edition is cited.

+## Where referenced standards conflict, the more stringent requirement shall govern unless the Architect directs otherwise in writing.

+# Quality Assurance {toc}

+## Fabricator Qualifications {toc}

+### The compartment fabricator shall be a firm regularly engaged in the production of toilet compartments in the panel material and mounting style specified, with not less than five years of production under its current ownership.

+### The fabricator shall furnish, on request, the location and date of not fewer than three installations of comparable size and service exposure using the specified panel material.

+## Source Compatibility of Panels and Hardware {toc}

+### Hardware preparations are machined into the door and pilaster at the factory, and the bracket spacing, hinge cutout, strike position, and edge profile are dimensioned to one fabricator's panel system. {note}

+### A hinge that does not match its preparation either will not seat in the cutout or will not carry the door in plane, and the resulting sag shows first as a door that will not latch. {note}

+### The panels, doors, pilasters, headrail, brackets, and hardware within a single restroom shall be furnished by a single fabricator.

+### Where the Owner directs that a hardware item be furnished separately from the compartments, the compartment fabricator shall machine the preparation for the designated item, and the party furnishing that item shall provide the preparation template before fabrication.

+## Field Dimension Verification {toc}

+### The clear dimensions of an accessible compartment depend on the as-built position of the walls, the water closet, and the floor drain, and none of those are reliably known from the contract drawings at the time the compartments are ordered. {note}

+### An accessible compartment fabricated to a drawing dimension that the field will not accommodate cannot be trimmed to fit, because every dimension in it is a code minimum. {note}

+### The Contractor shall verify field dimensions at each restroom before releasing the compartments for fabrication.

+### Where a field dimension will not accommodate an accessible compartment at its required clear dimensions, the Contractor shall notify the Architect in writing before fabrication and shall not proceed on the assumption that the difference can be absorbed in the installation.

+# Service Exposure and Cleaning Method {toc}

+## Moisture attacks a compartment at whatever part of the assembly is not itself waterproof: a composite core reached through a damaged edge, a steel substrate reached through a coating defect, or a fastener that is a dissimilar metal from the part it holds. {note}

+## Where a restroom is washed down with a hose or a pressure washer, water is driven into edges and fastener penetrations at a pressure that capillary action alone would never reach, and the panel material either has no absorbent interior for the water to enter or it does. {note}

+## Where chlorinated pool air or chloride-bearing coastal air is present, austenitic stainless steel is subject to pitting, and the resistance to that pitting differs between alloys rather than between finishes. {note}

+## Where a restroom is unsupervised, the loads that govern are prying at the door edge, impact at the panel face, and abrasion from graffiti removal, and none of them are moisture-related at all. {note}

+## The service exposure at each restroom shall be as indicated in the datasheet.

+```datasheet

+label: Service Exposure at Compartment Location

+type: select

+options:

+ - "Conditioned dry commercial restroom"

+ - "Restroom with elevated humidity from adjacent showers or steam"

+ - "Locker room or gang shower with wet garments and standing water"

+ - "Coastal or chloride-bearing exterior air"

+ - "Healthcare or food service restroom under frequent chemical disinfection"

+ - "Unsupervised public, park, or transit restroom"

+ - "Correctional or detention environment"

+ - "Unconditioned or exterior-adjacent restroom"

+```

+## The routine cleaning method at each restroom shall be as indicated in the datasheet.

+```datasheet

+options:

+ - "Damp mopping with spray-and-wipe cleaning of vertical surfaces"

+ - "Hose-down cleaning at domestic water pressure"

+ - "Pressure-washer cleaning"

+ - "Chemical disinfection with hospital-grade disinfectants"

+ - "Abrasive cleaning and periodic graffiti removal"

+```

+## Where hose-down or pressure-washer cleaning is indicated, the Contractor shall submit the fabricator's written confirmation that the selected panel material, hardware, and anchorage are rated for that cleaning method before fabrication.

+## Where the routine cleaning method includes a disinfectant or a graffiti remover that the care instructions exclude, the Contractor shall report the conflict to the Architect in writing before substantial completion.

+# Compartment Panel Material {toc}

+## Panel Material Selection {toc}

+### Panel material is the selection that sets service life, cleaning tolerance, and the hardware that can be attached, and it is made once per restroom rather than once per project. {note}

+### The panel material shall be as indicated in the datasheet.

+```datasheet

+label: Compartment Panel Material

+type: select

+options:

+ - "Plastic laminate faced panels over a composite core"

+ - "Solid plastic HDPE polymer"

+ - "Solid phenolic core"

+ - "Powder-coated steel over a honeycomb core"

+ - "Stainless steel over a honeycomb core"

+```

+### Where more than one panel material occurs in a project, each restroom shall be identified separately on the shop drawings with the material furnished at that location.

+### Panels, doors, and pilasters within a single restroom shall be furnished in one panel material unless the drawings indicate otherwise.

+## Panel, Door, and Pilaster Thickness {toc}

+### The panel takes distributed load and the door takes concentrated load, and the pilaster takes both plus the overturning moment from an occupant leaning on the door, which is why pilaster thickness is selected separately from panel thickness rather than following it. {note}

+### Thickness is not comparable across materials: solid phenolic reaches at half an inch a stiffness that solid plastic reaches near an inch, so a thickness value carries meaning only alongside the material selection. {note}

+### Where doors are levered or kicked, added door thickness increases the section at the lock edge and the depth of material the hinge fastener engages, both of which govern how a pry attack ends. {note}

+### The panel and door thickness shall be as indicated in the datasheet.

+```

+### Exposed panel, door, and pilaster edges shall be machined to a radius or banded so that no square-cut core edge is left exposed to the room.

+## Plastic Laminate Faced Panels {toc}

+### A plastic laminate faced panel is a decorative high-pressure laminate face bonded under heat and pressure to a composite core, with the perimeter edge banded to close the core against the room. {note}

+### The face laminate carries the color and the wear surface, and the core carries the strength, so the panel is only as waterproof as the weakest point in the edge band. {note}

+### Where an edge band is damaged, water reaches the core, the core swells, and the swelling breaks the bond between core and face, which is a failure of the assembly rather than of either material. {note}

+### The decorative face laminate shall conform to ANSI/NEMA LD 3.

+### The core substrate for plastic laminate faced panels shall be as indicated in the datasheet.

+```datasheet

+label: Core Substrate for Plastic Laminate Faced Panels

+type: select

+options:

+ - "Moisture-resistant particleboard core conforming to ANSI A208.1"

+ - "Exterior-grade or marine-grade plywood core"

+ - "Not applicable, no plastic laminate faced panels are furnished"

+```

+### The core shall be faced on both sides so that the panel is balanced and does not cup toward the unfaced side.

+### The perimeter edge of every panel, door, and pilaster shall be banded continuously, and the band shall be bonded so that no gap is open to the core at a corner.

+### Cutouts and hardware preparations made through a laminate faced panel shall be sealed at the exposed core before the hardware is installed.

+## Solid Plastic HDPE Panels {toc}

+### A solid plastic panel is one homogeneous sheet of high-density polyethylene with color running through the full thickness, so there is no face to delaminate and no core to absorb water. {note}

+### Because the color runs through, surface graffiti and shallow gouges are removed by sanding rather than by refinishing, and the repair leaves the panel the same color it started. {note}

+### HDPE does not support mildew growth and is unaffected by the disinfectants and detergents in ordinary restroom use, and it is also unaffected by standing water at a cut edge. {note}

+### HDPE expands and contracts with temperature more than the metals and composites it is fastened to, so a bracket run rigidly fixed at both ends of a long panel restrains movement the panel will make anyway. {note}

+### Solid plastic panels, doors, and pilasters shall be one homogeneous sheet of high-density polyethylene with color throughout the full thickness.

+### Tensile properties of the polymer shall be established in accordance with ASTM D638 and reported in the product data.

+### Machined edges shall be finished to a uniform radius, and machining marks shall not be visible on exposed edges.

+### Bracket and hardware attachments to solid plastic shall be made through oversized or slotted holes at all but one attachment point in a run, so that the panel can move with temperature without loading the fasteners.

+## Solid Phenolic Core Panels {toc}

+### A solid phenolic panel is built from layers of kraft paper saturated with phenolic resin and fused under heat and pressure into a single dense sheet, with the decorative surface formed in the same press rather than bonded on afterward. {note}

+### The compact-grade material carries a dark core that shows at every machined edge, which is a visual characteristic of the panel rather than a defect. {note}

+### Density is what phenolic trades for thickness: the panel resists impact and prying at a section thin enough that the compartment reads lighter than the same layout in another material. {note}

+### Where a restroom is hosed down, phenolic has no absorbent interior, and the water it takes on at a machined edge is a fraction of a percent by weight. {note}

+### Solid phenolic panels, doors, and pilasters shall be compact-grade high-pressure laminate conforming to ANSI/NEMA LD 3, Grade CGS.

+### The decorative surface shall be integral to the pressed panel and shall not be a laminate bonded to a separate core.

+### Machined edges shall be finished so that the core is smooth and closed, without fiber pull or resin chipping.

+## Powder-Coated Steel Panels {toc}

+### A powder-coated steel panel is two formed steel face sheets bonded to a core that separates them, which produces a stiff, light panel from thin sheet, and the coating is the only thing standing between the steel and the room. {note}

+### Corrosion of a steel panel starts at a coating defect and not on the intact painted face, so the corrosion resistance of the substrate under the coating governs how long the panel survives once the finish is broken. {note}

+### Where a zinc-coated substrate is used, the zinc corrodes preferentially at a scratch and keeps the steel from undercutting the coating outward from the defect. {note}

+### Where the panel edge is a formed seam rather than a continuous weld, water that enters the seam reaches the core and cannot evaporate out, which is why the seam and not the face is the location that governs in a wet restroom. {note}

+### The steel substrate for powder-coated panels shall be as indicated in the datasheet.

+```datasheet

+label: Steel Substrate for Powder-Coated Panels

+type: select

+options:

+ - "Galvannealed sheet steel, ASTM A653 A60 coating"

+ - "Hot-dip galvanized sheet steel, ASTM A653 G90 coating"

+ - "Cold-rolled carbon steel sheet, ASTM A1008"

+ - "Not applicable, no powder-coated steel panels are furnished"

+```

+### Steel components shall be cleaned, phosphatized, rinsed, and sealed before the finish coat is applied.

+### Components shall be formed, punched, and welded before the finish is applied, so that cut edges, formed radii, and hole edges receive coating.

+### Finish adhesion shall be not less than rating 4B when tested in accordance with ASTM D3359, Test Method B.

+### Finish impact resistance shall show no cracking and no loss of adhesion at 80 in-lbf direct impact when tested in accordance with ASTM D2794.

+### The minimum salt-spray exposure the powder-coat finish shall withstand without blistering or undercutting greater than 1/16 in. at the scribe shall be as indicated in the datasheet.

+```

+### Where a coated component is cut or drilled after finishing, the disturbed area shall be cleaned and touched up with the fabricator's matching coating before the compartment is placed in service.

+## Stainless Steel Panels {toc}

+### A stainless steel panel resists corrosion because a chromium oxide film re-forms on the exposed surface, which means a scratch heals rather than becoming the start of a corrosion cell. {note}

+### Where chlorides are present in the air or in the cleaning chemistry, that film is attacked locally, and the alloys differ in how well they resist the resulting pitting. {note}

+### Where a specular finish is used, the same reflectivity that gives the surface its appearance also returns a sharp image of every shallow scratch and fingerprint, and a textured or directional surface diffuses them. {note}

+### The stainless steel alloy shall be as indicated in the datasheet.

+```datasheet

+label: Stainless Steel Alloy

+type: select

+options:

+ - "Type 304, ASTM A666"

+ - "Type 316, ASTM A666"

+ - "Not applicable, no stainless steel panels are furnished"

+```

+### Where a directional finish is furnished, the direction of the polish lines shall be consistent across every panel, door, and pilaster in a restroom.

+### Exposed stainless steel surfaces shall be protected with a strippable film through delivery and installation, and the film shall be removed without leaving adhesive residue.

+# Interior Finish Fire Performance {toc}

+## The model building codes regulate toilet compartments as interior finish, and the test method that establishes compliance depends on the material rather than on the compartment. {note}

+## Non-plastic panel materials are classified by flame spread and smoke developed indices from the ASTM E84 tunnel test, which reports a class. {note}

+## Plastic panel materials, including HDPE, are evaluated by the NFPA 286 room-corner test, which reports a pass or a failure against acceptance criteria rather than a class, because the tunnel geometry does not represent how a thermoplastic behaves when it softens and drips. {note}

+## The interior finish classification required for the compartments shall be as indicated in the datasheet.

+```datasheet

+label: Required Interior Finish Classification

+type: select

+options:

+ - "Class A"

+ - "Class B"

+ - "Class C"

+ - "Not regulated as interior finish by the adopted code"

+```

+## Non-plastic panel materials shall be tested in accordance with ASTM E84 or UL 723 and shall meet the classification indicated in the datasheet.

+## Plastic panel materials shall be tested in accordance with NFPA 286 and shall meet the acceptance criteria of that method where the adopted code requires room-corner testing of plastic interior finish.

+## The Contractor shall submit the test report that establishes compliance for the selected panel material before fabrication.

+## Where the Authority Having Jurisdiction and the Contractor disagree on which test method applies to the selected material, the Architect shall obtain the ruling of the Authority Having Jurisdiction in writing before fabrication.

+# Color and Surface Finish Selection {toc}

+## Color availability is a catalog fact rather than a project requirement, and the selection question is whether the project takes the standard line, contrasts doors against panels, or pays lead time for a match outside the line. {note}

+## Where a color is matched to a submitted sample, the match is made in the material the panel is built from, and a color that is achievable in a powder coat is not necessarily achievable in a through-color polymer. {note}

+## The color and finish selection basis shall be as indicated in the datasheet.

+```datasheet

+label: Color and Finish Selection Basis

+type: radio

+options:

+ - "Selected from the full standard color line offered for the panel material"

+ - "Two-tone, doors one color and panels another"

+ - "Multiple colors distributed across compartments or restrooms"

+ - "Custom color matched to a submitted sample"

+```

+## Where a custom color match is indicated, the Contractor shall submit a coated or pressed sample of the actual panel material for approval and shall state the added lead time on the transmittal before fabrication is released.

+## Where more than one color is used, the shop drawings shall identify the color of every panel, door, and pilaster by restroom and by compartment.

+# Mounting Style and Overhead Support {toc}

+## Mounting Style Selection {toc}

+### The mounting style decides where the compartment load goes and what resists lateral force at the top of the pilaster, and those are properties of the building rather than of the compartment. {note}

+### In a floor-anchored and overhead-braced installation, the pilaster carries vertical load to the floor and a continuous headrail spanning the pilaster tops and anchored to the walls resists lateral force, which requires nothing of the structure above the ceiling. {note}

+### In a floor-to-ceiling installation, the pilaster is anchored at both ends, so lateral force is resisted as a fixed-end condition rather than by a headrail, and the pilaster becomes the stiffest element in the assembly. {note}

+### In a ceiling-hung installation, the pilaster is suspended from overhead structure and does not touch the floor, which leaves the floor clear for wet cleaning and puts the entire compartment load, including the moment from an occupant pulling on a door, into the structure above. {note}

+### In a floor-anchored installation without a headrail, the pilaster acts as a vertical cantilever off its floor anchorage, and the resistance to lateral force at the top of the pilaster is whatever that anchorage and the pilaster section provide. {note}

+### Where a suspended acoustical ceiling is the only overhead construction, a ceiling-hung or floor-to-ceiling installation requires structure added above the ceiling, and that structure is furnished by the trades who build it rather than under this standard. {note}

+### The mounting style shall be as indicated in the datasheet.

+```datasheet

+label: Mounting Style

+type: select

+options:

+ - "Floor-anchored and overhead-braced"

+ - "Floor-to-ceiling"

+ - "Ceiling-hung"

+ - "Floor-anchored without headrail"

+```

+### Where ceiling-hung or floor-to-ceiling mounting is selected, the overhead structural support at each pilaster shall be [[drawing: as indicated on the reflected ceiling plan and the structural framing drawings]].

+### The Contractor shall verify that the overhead structural support is in place and accessible before the compartments are delivered to the restroom.

+### Pilasters shall not be anchored to a suspended ceiling grid, to a ceiling membrane, or to any assembly not designed to carry the compartment load.

+## Headrail {toc}

+### A headrail is a compression and tension member, and it is also the part of the compartment a person can hang weight on, so its top profile is shaped to shed a grip rather than accept one. {note}

+### The headrail type shall be as indicated in the datasheet.

+```datasheet

+label: Headrail Type

+type: select

+options:

+ - "Anti-grip extruded aluminum headrail, clear anodized"

+ - "Anti-grip extruded aluminum headrail, color anodized"

+ - "Anti-grip stainless steel headrail"

+ - "Tubular extruded aluminum headrail"

+ - "No headrail furnished"

+```

+### Extruded aluminum headrails shall conform to ASTM B221.

+### The headrail shall be continuous over the full length of each compartment run, with splices occurring only at a pilaster.

+### The headrail shall be anchored to the wall at each end of the run into solid blocking or into masonry.

+### Where a headrail is furnished, it shall be attached to every pilaster in the run and not to alternating pilasters.

+## Pilaster Shoes {toc}

+### A pilaster shoe conceals the floor anchorage and closes the joint between the pilaster and the floor, which is also the joint that a mop and standing water reach first. {note}

+### The pilaster shoe shall be as indicated in the datasheet.

+```datasheet

+label: Pilaster Shoe

+type: select

+options:

+ - "Type 304 stainless steel shoe"

+ - "Type 316 stainless steel shoe"

+ - "Powder-coated steel shoe"

+ - "Anodized aluminum shoe"

+ - "Molded polymer shoe"

+ - "No pilaster shoe furnished"

+```

+### Where a pilaster shoe is furnished, it shall conceal the floor anchorage and the leveling shims completely.

+### The shoe shall be secured so that it cannot be lifted or rotated by hand once installed.

+# Compartment Dimensions and Privacy {toc}

+## Compartment and Door Dimensions {toc}

+### Compartment width, depth, and door width are set by the fixture layout, the accessible-route arrangement, and the floor area the restroom occupies, so they are project dimensions rather than product norms and carry no assumed value. {note}

+### The clear width of a compartment door is measured with the door open, not as the door leaf width, because hardware and the door thickness at the hinge stile both take from the leaf. {note}

+### The compartment width for compartments other than accessible compartments shall be as indicated in the datasheet.

+```datasheet

+default: deferred

+```

+### Every compartment width and depth shown on the shop drawings shall be a clear dimension between the finished faces of the enclosing panels and pilasters, not a nominal or centerline dimension.

+## Panel Height and Floor Clearance {toc}

+### Panel height and the clearance below the panel together set how much of the occupant is screened, and they are two independent dimensions rather than one privacy setting. {note}

+### Where the clearance below the panel is reduced, the compartment gains visual privacy and loses the open path a mop, a floor machine, and airflow use, and the same clearance is what provides the toe clearance an accessible compartment can be sized against. {note}

+### Where the panel is raised to full height, the compartment becomes an enclosed volume, and exhaust airflow into and out of it depends on a path that the panel no longer provides. {note}

+### The panel and door height shall be as indicated in the datasheet.

+```datasheet

+label: Panel and Door Height

+type: range

+unit: in

+drawing_ref: "as indicated on the interior elevations"

+default: deferred

+```

+### Where the clearance below the panel is relied upon to provide the toe clearance of an accessible compartment, the clearance shall satisfy the toe clearance requirements of this standard.

+### Where a reduced floor clearance is indicated, the Contractor shall confirm with the Owner's housekeeping staff that the restroom cleaning equipment can operate at that clearance before fabrication.

+## Sightline Treatment {toc}

+### The gap between a door edge and the pilaster is a manufacturing clearance that lets the door swing, and it is also a direct line of sight into the compartment from the room. {note}

+### Where that gap is closed by an overlapping stile or a filler strip, the door still swings on the same hardware, and the added section at the door edge also removes the pry point a flat gap presents. {note}

+### The sightline treatment at door and pilaster edges shall be as indicated in the datasheet.

+```datasheet

+label: Door and Pilaster Sightline Treatment

+type: select

+options:

+ - "Standard swing clearance at door and pilaster edges"

+ - "Overlapping door stile at the latch edge"

+ - "Overlapping door stile at the latch and hinge edges"

+ - "Continuous filler strip applied at the pilaster edge"

+ - "Full-height door and panel with no gap at the pilaster"

+```

+### Where a sightline treatment other than standard swing clearance is indicated, the shop drawings shall show the treatment in section at the door edge and at the pilaster.

+# Compartment Hardware {toc}

+## Hardware is where a compartment is touched, loaded, and attacked, and it is also the part that is replaced during the service life while the panels stay, so the hardware selection is made against the abuse the restroom sees rather than against the panel material. {note}

+## Every hardware item exposed within the compartment shall be free of sharp edges, burrs, and projecting points.

+## Hinges {toc}

+### A hinge carries the door weight through every cycle, and the point where a hinge attaches to the door edge is the location where a heavily used door fails first. {note}

+### A gravity cam hinge lifts the door slightly as it opens and lets gravity return it, so the door is self-closing without a spring and the rest position is set by rotating the cam. {note}

+### A continuous hinge carries the load along the full door height rather than at two or three points, which removes both the concentrated load at the fastener and the pinch and pry points between the leaves. {note}

+### Where the door is expected to rest partially open when the compartment is unoccupied, that rest position is a visible vacancy cue from across the room, and where the door is expected to rest closed, the compartment reads as private whether occupied or not. {note}

+### The hinge type shall be as indicated in the datasheet.

+```datasheet

+label: Hinge Type

+type: select

+options:

+ - "Gravity cam hinge"

+ - "Spring-action hinge with adjustable tension"

+ - "Continuous piano hinge over the full door height"

+ - "Concealed pivot hinge"

+ - "Surface-mounted wrap-around hinge"

+```

+### The rest position of an unlatched door shall be as indicated in the datasheet.

+```datasheet

+label: Unlatched Door Rest Position

+type: radio

+options:

+ - "Door rests partially open when unlatched"

+ - "Door rests closed when unlatched"

+```

+### Hinges shall be adjustable in the field so that the rest position can be set after installation without removing the door.

+### Hinge fasteners shall engage a reinforced or doubled thickness of material at the door edge, or shall be through-bolted, and shall not be driven into a single thickness of a composite core.

+## Latch, Strike, and Keeper {toc}

+### The latch, the strike it engages, and the keeper that stops the door are one working assembly, and a latch that engages a strike out of position will bind, rattle, or fail to hold. {note}

+### The keeper also serves as the door stop, so the bumper it carries is what absorbs the closing impact instead of the panel edge. {note}

+### Where a latch is attacked, the failure is usually the fastener pulling through the door face rather than the latch body itself, which is why a through-bolted latch on a continuous strike resists what a surface-screwed latch does not. {note}

+### The latch type shall be as indicated in the datasheet.

+```datasheet

+label: Latch Type

+type: select

+options:

+ - "Slide latch with strike and keeper"

+ - "Slide latch with vacant and occupied indicator"

+ - "Surface-mounted heavy-gauge latch with continuous strike"

+ - "Thumb-turn deadbolt latch with strike and keeper"

+ - "Lever-operated latch with strike and keeper"

+```

+### The strike and keeper shall be furnished with a resilient bumper that stops the door before the door edge contacts the pilaster.

+### The latch shall engage the strike at full throw with the door in its closed position and shall release without the user lifting or pulling the door.

+### The latch and strike shall be positioned so that the latch cannot be released by reaching over or under the door with a hand or a tool where the compartment is indicated as vandal-resistant.

+## Emergency Access {toc}

+### A latched compartment holding an occupant who cannot release the latch is a rescue problem, and the means of entry has to exist before it is needed rather than being improvised on the door. {note}

+### The emergency access provision shall be as indicated in the datasheet.

+```datasheet

+label: Emergency Access Provision

+type: select

+options:

+ - "Door lifts off the gravity hinge cam from outside the compartment"

+ - "Latch releasable from outside with a coin slot or common tool"

+ - "Latch releasable from outside with a keyed emergency release"

+ - "Door swing reversible from outswing to inswing without door removal"

+ - "No emergency access provision furnished"

+```

+### Where an emergency access provision is furnished, the Contractor shall demonstrate its operation to the Owner at substantial completion and shall record the demonstration in the closeout submittals.

+## Panel and Pilaster Brackets {toc}

+### A bracket transfers panel load into the pilaster or the wall, and the difference between bracket types is how far that load is spread along the joint. {note}

+### A point bracket concentrates the load at two connections, so a lever applied to the free edge of the panel works against those two points, while a full-height bracket resists the same lever along the entire joint and leaves no gap to insert a tool into. {note}

+### The panel and pilaster bracket type shall be as indicated in the datasheet.

+```datasheet

+label: Panel and Pilaster Bracket Type

+type: select

+options:

+ - "Stirrup brackets at the top and bottom of each panel"

+ - "Full-height continuous bracket at each panel connection"

+ - "Powder-coated steel"

+ - "Molded polymer"

+```

+### Brackets shall be anchored to walls into solid blocking, into masonry, or into concrete, and shall not be anchored to gypsum board alone.

+### Brackets fastened to a solid plastic panel shall permit the panel to move with temperature at all but one attachment point in the run.

+## Hardware Material and Plating {toc}

+### Hardware and the panel it fastens to are frequently different metals, and where the restroom is wet the joint between them is an electrolytic cell that corrodes the less noble of the two. {note}

+### On plated hardware the plating rather than the base metal does the corrosion work, and the plating grade is what separates a hardware set that survives a locker room from one that survives an office. {note}

+### The door hardware material shall be as indicated in the datasheet.

+```datasheet

+```

+### Hardware, fasteners, and the components they join shall be selected so that no dissimilar-metal pair is left in direct contact where the service exposure indicated in the datasheet includes standing water, chlorides, or hose-down cleaning.

+## Coat Hook and Door Bumper {toc}

+### The hook on the inside face of the door holds a garment, and the bumper behind it stops the door before the hook itself strikes the panel or an occupant. {note}

+### The coat hook and bumper provision shall be as indicated in the datasheet.

+```datasheet

+```

+### Coat hooks shall be attached through a reinforced thickness of material or through-bolted, and shall not be fastened into a single thickness of a composite core.

+## Exposed Fasteners {toc}

+### An exposed fastener head is the interface a hand tool needs, so the head type decides whether a compartment can be disassembled by anyone carrying an ordinary screwdriver. {note}

+### The exposed fastener head type shall be as indicated in the datasheet.

+```datasheet

+label: Exposed Fastener Head Type

+type: select

+options:

+ - "Slotted or cross-recess head"

+ - "Hex socket head"

+ - "One-way slotted head"

+ - "Spanner head"

+```

+### Exposed fasteners shall be stainless steel conforming to ASTM F593 where the service exposure indicated in the datasheet includes standing water, chlorides, or hose-down cleaning.

+### Panel-to-pilaster and bracket connections shall be through-bolted where the compartment is indicated as vandal-resistant, and shall not be fastened into the panel face alone.

+# Urinal and Dressing Screens {toc}

+## A urinal screen is a single panel with no door and no compartment behind it, so all of the load an occupant can apply to it goes through one connection line. {note}

+## A wall-hung screen is a cantilever off the wall, and the moment at the wall connection is the full weight of anyone who leans on the free edge, which is why a screen anchored to gypsum board without blocking works loose under ordinary use rather than under abuse. {note}

+## The location and quantity of urinal screens and dressing screens shall be [[drawing: as indicated on the restroom plans and interior elevations]].

+# Accessible Compartments {toc}

+## Quantity, Type, and Location {toc}

+### Two distinct compartment types are recognized by the accessibility standards, and a restroom can be required to have both: a wheelchair accessible compartment sized for a wheelchair to enter, turn, and transfer, and an ambulatory accessible compartment sized narrow enough that a standing user can reach a grab bar on each side. {note}

+### An ambulatory accessible compartment is required in addition to the wheelchair accessible compartment where six or more toilet compartments are provided in a toilet room, or where the combination of water closets and urinals totals six or more fixtures. {note}

+### Wheelchair accessible compartments shall be provided in accordance with the adopted accessibility standard.

+### An ambulatory accessible compartment shall be provided in addition to the wheelchair accessible compartment where the fixture count of the toilet room reaches the threshold set by the adopted accessibility standard.

+### The number, type, and location of accessible compartments shall be [[drawing: as indicated on the restroom plans and the accessibility compliance drawings]].

+### Accessible compartments shall be arranged for the approach hand [[drawing: as indicated on the restroom plans]].

+### The requirements of this section state the dimensions of the 2010 ADA Standards and ICC A117.1, and where the Authority Having Jurisdiction has adopted a different edition or a more stringent standard, that requirement shall govern.

+## Wheelchair Accessible Compartment Size {toc}

+### The wheelchair accessible compartment dimensions are clear dimensions to the finished face of the enclosing partitions, so a thicker panel selection consumes compartment width rather than being absorbed by it. {note}

+### A wheelchair accessible compartment shall be 60 in. minimum wide, measured perpendicular to the side wall.

+### A wheelchair accessible compartment serving a wall-hung water closet shall be 56 in. minimum deep, measured perpendicular to the rear wall.

+### A wheelchair accessible compartment serving a floor-mounted water closet shall be 59 in. minimum deep, measured perpendicular to the rear wall.

+### The water closet in a wheelchair accessible compartment shall be located with its centerline 16 in. minimum and 18 in. maximum from the side wall or partition.

+### The wheelchair accessible compartment shall be arranged so that the required clear floor space at the water closet is not reduced by the compartment door, by a panel-mounted accessory, or by a grab bar support.

+## Toe Clearance at Accessible Compartments {toc}

+### Toe clearance below a partition lets a wheelchair footrest and the user's feet occupy space that the compartment plan does not otherwise provide, which is why omitting it enlarges the compartment instead of eliminating a requirement. {note}

+### Where the compartment is enlarged under the exception instead, the enlargement is specific to each partition: omitting toe clearance at the front partition drives depth, and omitting it at the side partition drives width. {note}

+### The toe clearance approach at wheelchair accessible compartments shall be as indicated in the datasheet.

+```datasheet

+label: Toe Clearance Approach at Wheelchair Accessible Compartments

+type: radio

+options:

+ - "Toe clearance provided below the front partition and one side partition"

+ - "Toe clearance omitted and the compartment enlarged under the exception"

+default: "Toe clearance provided below the front partition and one side partition"

+```

+### Where toe clearance is provided, the front partition and at least one side partition shall provide a toe clearance of 9 in. minimum above the finished floor and 6 in. minimum deep beyond the compartment-side face of the partition, exclusive of partition support members.

+### Toe clearance in a compartment for children's use shall be 12 in. minimum above the finished floor.

+### Where toe clearance is not provided at the front partition, the compartment shall be greater than 62 in. deep with a wall-hung water closet or greater than 65 in. deep with a floor-mounted water closet.

+### Where toe clearance is not provided at the side partition, the compartment shall be greater than 66 in. wide.

+## Ambulatory Accessible Compartment Size {toc}

+### An ambulatory accessible compartment is bounded at both a minimum and a maximum width, because a compartment wider than the maximum puts the second grab bar out of reach of a standing user. {note}

+### An ambulatory accessible compartment shall be 35 in. minimum and 37 in. maximum wide.

+### An ambulatory accessible compartment shall be 60 in. minimum deep.

+### The water closet in an ambulatory accessible compartment shall be located with its centerline 17 in. minimum and 19 in. maximum from the side partition.

+### Grab bars shall be provided on both side partitions of an ambulatory accessible compartment, and the compartment shall be furnished with the reinforcement required to support them.

+## Accessible Compartment Doors {toc}

+### The accessible compartment door is where the compartment most often fails inspection, because the door swing, the door position along the partition, and the clearance outside the compartment are three separate requirements that interact. {note}

+### A door that swings into the compartment consumes the same floor area the wheelchair needs, so an inswing door is workable only where the compartment is enlarged beyond its minimum by at least the area the swing takes. {note}

+### The accessible compartment door location shall be as indicated in the datasheet.

+```datasheet

+label: Accessible Compartment Door Location

+type: radio

+drawing_ref: "as indicated on the restroom plans"

+options:

+ - "In the front partition"

+ - "In the side wall or partition farthest from the water closet"

+default: deferred

+```

+### The accessible compartment door swing shall be as indicated in the datasheet.

+```datasheet

+label: Accessible Compartment Door Swing

+type: radio

+drawing_ref: "as indicated on the restroom plans"

+options:

+ - "Outswing, away from the compartment"

+ - "Inswing, into a compartment enlarged so the swing does not encroach"

+default: deferred

+```

+### The accessible compartment door shall provide a clear opening width of 32 in. minimum measured with the door open 90 degrees.

+### The accessible compartment door shall not swing into the minimum required compartment area.

+### Where the door is located in the front partition, the door opening shall be 4 in. maximum from the side partition farthest from the water closet.

+### Where the door is located in the side wall or partition, the door opening shall be 4 in. maximum from the front partition.

+### The accessible compartment door shall be self-closing.

+### Door pulls shall be provided on both the inside and the outside face of the accessible compartment door, near the latch.

+### Where the approach to the accessible compartment door is to the latch side, the clearance between the door side of the compartment and the nearest obstruction shall be 42 in. minimum.

+### The Contractor shall verify after final adjustment that each accessible compartment door achieves its clear opening width, closes fully under its self-closing action, and latches without the user lifting or pulling the door.

+## Operable Parts and Accessory Coordination {toc}

+### An accessible compartment can meet every dimension and still fail because a latch requires a pinch to release or a hook sits above the reach range, since the compartment is judged on what the user must operate as well as on where the partitions stand. {note}

+### Grab bars, dispensers, and receptacles are furnished under [[sync/toilet-accessories]], but where one of them mounts to a compartment panel rather than to a wall, the panel is the structure carrying it, and only the compartment fabricator can build that reinforcement in. {note}

+### Every operable part of an accessible compartment, including the latch, the door pull, and the coat hook, shall be operable with one hand, without tight grasping, pinching, or twisting of the wrist, and with an operating force of not more than 5 lbf.

+### Door pulls and latch hardware on accessible compartment doors shall be mounted 34 in. minimum and 48 in. maximum above the finished floor.

+### A coat hook serving an accessible compartment shall be located within the forward or side reach range of 15 in. minimum and 48 in. maximum above the finished floor.

+### A shelf serving an accessible compartment shall be located 40 in. minimum and 48 in. maximum above the finished floor.

+### Where the latch selected for the typical compartments requires pinching, tight grasping, or twisting of the wrist to operate, a latch meeting the operable-parts requirements shall be furnished on the accessible compartments.

+### The panel reinforcement furnished at accessible compartments shall be as indicated in the datasheet.

+```datasheet

+label: Panel Reinforcement at Accessible Compartments

+type: checkbox

+options:

+ - "Reinforcement for a side-wall grab bar mounted to a panel"

+ - "Reinforcement for a rear-wall grab bar mounted to a panel"

+ - "Reinforcement for a toilet paper dispenser mounted to a panel"

+ - "Reinforcement for a seat-cover dispenser mounted to a panel"

+ - "Reinforcement for an accessible-height coat hook"

+ - "Reinforcement for a shelf mounted to a panel"

+ - "No panel reinforcement required, all accessories mount to walls"

+default:

+ - "Reinforcement for a side-wall grab bar mounted to a panel"

+ - "Reinforcement for a toilet paper dispenser mounted to a panel"

+ - "Reinforcement for an accessible-height coat hook"

+```

+### The compartment shop drawings shall show the location of every accessory serving an accessible compartment and the reinforcement provided for it.

+### Panel reinforcement for a grab bar shall be sized to develop the grab bar design load required by the adopted accessibility standard without deflection of the panel at the connection.

+# Fabrication {toc}

+## Compartments shall be fabricated to the dimensions and configuration shown on the shop drawings returned for fabrication.

+## Doors, panels, and pilasters shall be fabricated square, so that a door hangs with a uniform gap along the full height of the opening at both the hinge and the latch edge.

+## Hardware preparations shall be machined at the factory to the position shown on the shop drawings, and shall not be cut in the field.

+## Sheared, formed, machined, and punched edges within reach of an occupant shall be free of burrs and sharp edges.

+## Components shall be identified by the fabricator with a mark that ties each component to its location on the shop drawings, and the mark shall be concealed after installation.

+# Delivery, Storage, and Handling {toc}

+## A compartment damaged before installation cannot be repaired to match, because neither a pressed decorative surface nor a baked coating can be reproduced in the field, so handling damage becomes a replacement and a schedule delay rather than a touch-up. {note}

+## Compartments shall be delivered in the fabricator's packaging, with protective wrapping on finished surfaces intact.

+## Compartments shall be stored inside a weathertight, conditioned space, off the floor, and shall not be stored where condensation forms on the packaging.

+## Compartments shall not be delivered to the site until the restroom is enclosed, the wet trades are complete, and the space is at the temperature and humidity at which it will be occupied.

+## Solid plastic components shall be stored flat and fully supported, and shall not be leaned against a wall for an extended period at a temperature above the conditioned range.

+## Damaged components shall be replaced rather than field-repaired, except that damage not visible in the installed position may be repaired by the method the care instructions permit for that material.

+## The Contractor shall bear the cost of replacing components damaged in delivery, storage, or handling.

+# Installation {toc}

+## Blocking and Substrate Preparation {toc}

+### A compartment anchored to gypsum board without blocking pulls loose under ordinary use, and the failure appears months after acceptance when the fastener finally works through the board face. {note}

+### The Contractor shall verify, before installation begins, that solid in-wall blocking has been installed at every location where a pilaster, a panel, a bracket, a headrail, or a screen anchors to a wall.

+### Where blocking is missing or mislocated, the Contractor shall notify the Architect in writing before proceeding and shall not proceed with wall anchorage at that location.

+### Compartments, screens, and headrails shall not be anchored to gypsum board alone.

+### Compartments shall be installed after the wall and floor finishes are complete and the building is enclosed and conditioned.

+### The floor at each pilaster location shall be verified level within the tolerance the fabricator requires for the mounting style, and shall be shimmed rather than ground where it is out of tolerance.

+## Setting and Anchorage {toc}

+### Anchors shall be selected for the substrate they engage, using expansion or screw anchors in concrete, anchors rated for the unit in masonry, and through-bolts or lag screws into solid blocking in stud walls.

+### Floor anchorage of a pilaster shall develop the full design load of the selected mounting style, including the overturning moment from an occupant leaning on an open door.

+### Anchorage shall not be made through the finished flooring in a manner that breaches a waterproof membrane, and where a membrane is present the anchorage method shall be coordinated with the waterproofing trade before installation.

+### Anchorage hardware installed where the service exposure indicated in the datasheet includes standing water, chlorides, or hose-down cleaning shall be stainless steel.

+### Where a compartment is set on a floor with a drain slope, the pilaster shall be shimmed plumb rather than set to the slope, and the resulting variation in floor clearance shall be absorbed at the pilaster shoe.

+## Alignment and Adjustment {toc}

+### A door that is out of alignment shows as a latch that will not engage, and correcting it after the panels are anchored means loosening and resetting the run rather than adjusting the door. {note}

+### The pilaster plumb tolerance over the full pilaster height shall be as indicated in the datasheet.

+```datasheet

+label: Pilaster Plumb Tolerance Over Full Height

+type: range

+unit: in

+min: 0.0625

+max: 0.25

+setpoints: [0.0625, 0.125, 0.25]

+default: 0.125

+```

+### Panels shall be installed level, and doors shall be hung so that the gap at the hinge edge and the gap at the latch edge are uniform over the full door height.

+### Compartments shall not be forced into alignment by tightening brackets or anchors against a run that is out of plumb.

+### The Contractor shall adjust every hinge after installation so that the door returns to the rest position indicated in the datasheet and the latch engages the strike at full throw.

+### Doors that bind, latches that do not engage at full throw, and self-closing doors that do not close fully shall be corrected by the Contractor before substantial completion.

+## Cleaning and Protection {toc}

+### The Contractor shall clean all exposed surfaces using a method and an agent the care instructions for the installed panel material permit.

+### Protective coverings shall remain in place until adjustment and cleaning are complete, and shall be removed without leaving adhesive residue on the finish.

+### Components with damage visible in the installed position, and components showing corrosion, shall be replaced at the Contractor's cost.

+# Warranty {toc}

+## A warranty that runs from the date of shipment rather than from substantial completion can be substantially expired before the building is occupied, so the start date is as much a part of the selection as the duration. {note}

+## The manufacturer warranty period, measured from substantial completion, shall be as indicated in the datasheet.

+```datasheet

+label: Manufacturer Warranty Period

+type: range

+unit: yr

+min: 1

+max: 25

+setpoints: [1, 2, 3, 5, 10, 15, 20, 25]

+```

+## The manufacturer shall warrant the compartments against defects in materials and workmanship, including delamination, corrosion, breakage, finish adhesion, and hardware operation, for the specified period measured from the date of substantial completion.

+## Where the manufacturer offers a longer or lifetime limited warranty on the panel material selected, that warranty shall be furnished in addition to the period specified, and its terms and exclusions shall be submitted at closeout.

+## The Contractor installation warranty period, measured from substantial completion, shall be as indicated in the datasheet.

+```datasheet

+label: Contractor Installation Warranty Period

+type: range

+unit: yr

+min: 1

+max: 5

+setpoints: [1, 2, 3, 5]

+default: 1

+```

+## The Contractor shall warrant the installation, including anchorage, plumb and level setting, door alignment, hardware operation, and the dimensional and operable-parts compliance of the accessible compartments, for the specified period.

+## Deficiencies attributable to installation workmanship shall be corrected by the Contractor at no cost to the Owner, including the cost of removing and reinstalling adjacent work required to reach the deficiency.

+## Where a warranted component is repaired or replaced, the repaired or replaced component shall carry a warranty running for the full original period from the date of the repair, or for the remainder of the original period, whichever ends later.

+## The warranty shall not cover damage from use beyond the service exposure indicated in the datasheet, from cleaning agents the care instructions exclude, or from modification of the compartment without the fabricator's written authorization.

+## Where the parties disagree whether an observed condition is a warranted defect or damage from use, the Architect shall make the initial determination.

+# Spare Parts {toc}

+## A compartment line discontinued a few years after installation leaves the Owner replacing a whole run to repair one door, and hardware is the part that is consumed first. {note}

+## The attic stock furnished to the Owner shall be as indicated in the datasheet.

+```datasheet

+label: Attic Stock Furnished

+type: checkbox

+options:

+ - "Spare hinges of each installed type"

+ - "Spare latch, strike, and keeper sets"

+ - "Spare coat hooks and bumpers"

+ - "Spare brackets of each installed type"
