1 Scope
NOTE This standard covers the furnishing and installation of factory-fabricated toilet compartments and urinal screens for commercial and institutional restrooms. (1.1)
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. (1.2)
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. (1.3)
NOTE This standard establishes the material, fabrication, hardware, accessibility, and installation requirements for those compartments. (1.4)
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. (1.5)
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. (1.6)
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. (1.7)
NOTE Coordinate this work with
Toilet Accessories for grab bars, dispensers, and receptacles that mount on or adjacent to compartments; with
Plumbing Fixtures for the water closets and urinals the compartments enclose; with
Gypsum Board Assemblies and
Unit Masonry for in-wall blocking and anchorage backing; and with the finished flooring and base trades for floor anchorage conditions.

4.1.2Compartments, pilasters, doors, and hardware within a single restroom shall be the product of a single manufacturer to ensure dimensional and finish compatibility.
4.2 Single-Source Responsibility
4.2.1The 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.
○ All compartments, screens, and hardware from a single manufacturer
○ Compartments and accessories furnished as a coordinated package by a single supplier
4.2.2Mixing pilasters from one manufacturer with doors or hardware from another voids the fit of factory-machined hardware preparations and shall not be permitted.
4.3 Field Measurements
NOTE 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. (4.3.1)
4.3.2The Contractor shall verify field dimensions of each restroom before fabrication.
4.3.3Where 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.
5 Service Conditions and Material Selection
5.1 Moisture, Humidity, and Abuse Classification
NOTE 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. (5.1.1)
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
5.1.2The compartment material shall be selected for the moisture exposure, humidity, traffic, and abuse anticipated at the specific restroom.
5.2 Material Selection by Occupancy
NOTE 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. (5.2.1)
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. (5.2.2)
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. (5.2.3)
5.2.4Material selection should follow the service condition.
5.2.5Powder-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.
6 Compartment Materials
6.1 High-Pressure Decorative Laminate (HPL)
NOTE 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. (6.1.1)
NOTE HPL provides a wide range of colors and patterns at moderate cost and is the standard selection for dry commercial restrooms. (6.1.2)
○ Moisture-resistant particleboard core (standard interior)
○ Marine-grade / exterior-rated substrate (elevated moisture)
6.1.3HPL 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.
6.2 Solid Plastic (HDPE Polymer)
NOTE 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. (6.2.1)
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. (6.2.2)
NOTE Solid plastic is the default material for high-traffic public restrooms, schools, stadiums, and wet environments. (6.2.3)
○ NFPA 286 room-corner test report provided (plastic interior finish)
○ Class B flame-spread per ASTM E84 (where AHJ accepts for the occupancy)
6.2.4Because 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.
6.3 Solid Phenolic Core
NOTE 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. (6.3.1)
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. (6.3.2)
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. (6.3.3)
6.4 Powder-Coated Steel
NOTE 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. (6.4.1)
NOTE Powder-coated steel is the most economical material and is appropriate for dry, standard commercial restrooms. (6.4.2)
○ 22 gauge face sheets (standard)
○ 20 gauge face sheets (heavier duty)
6.4.3Powder-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.
6.5 Stainless Steel
NOTE 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. (6.5.1)
NOTE Stainless steel is corrosion-resistant, cleanable, and appropriate for healthcare, food service, and high-design applications. (6.5.2)
○ Type 304 — standard corrosion resistance
○ Type 316 — elevated corrosion resistance (coastal, chemical, high-chloride)
No. 4 satin (directional brushed)
Textured / patterned (vandal-resistant, hides scratches)
No. 8 mirror (high-design, low-abuse only)
6.5.3A 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.
6.6 Compartment Material Selection
NOTE This is the governing material decision for the standard. (6.6.1)
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. (6.6.2)
High-pressure decorative laminate (HPL)
Solid plastic (HDPE polymer)
Solid phenolic core
Powder-coated steel
Stainless steel
6.6.3The compartment material shall be selected from the service condition and confirmed per restroom on the shop drawings where conditions differ.
7 Mounting Styles
NOTE The mounting style determines how the pilasters transfer load to the structure and how the compartment is braced against lateral force. (7.1)
NOTE The choice depends on the ceiling type and height, the floor construction, and the available overhead structure. (7.2)
Floor-anchored / overhead-braced
Floor-to-ceiling
Ceiling-hung
Floor-mounted (no headrail)
7.3Mounting style shall be selected per restroom and confirmed against the reflected ceiling plan and the structural conditions above the ceiling.
7.4Headrail shall be continuous anti-grip extruded aluminum at all overhead-braced installations.
7.5Pilaster floor anchorage shall be concealed by a stainless steel pilaster shoe at floor-anchored and floor-to-ceiling installations.
7.6 Floor-Anchored / Overhead-Braced
NOTE 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. (7.6.1)
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. (7.6.2)
NOTE It tolerates a wide range of ceiling heights and does not require overhead structure for support. (7.6.3)
7.6.4The 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.
7.7 Floor-to-Ceiling
NOTE In the floor-to-ceiling style, pilasters are anchored to both the floor and overhead structure, producing the most rigid and abuse-resistant installation. (7.7.1)
NOTE It is preferred for high-abuse, correctional, and heavy-use public applications, and where the design intent is a full-height appearance. (7.7.2)
7.7.3Floor-to-ceiling mounting requires structural support above the ceiling at each pilaster; the Contractor shall coordinate overhead blocking or structure before fabrication.
7.8 Ceiling-Hung
NOTE 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. (7.8.1)
NOTE It is favored in healthcare and high-cleanliness applications because the open floor simplifies wet cleaning. (7.8.2)
7.8.3Ceiling-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.
7.9 Floor-Mounted
NOTE In the floor-mounted style, pilasters are anchored to the floor only, with no overhead headrail or ceiling attachment. (7.9.1)
NOTE It is limited to short pilaster runs and low-abuse applications where lateral bracing from a headrail is not required. (7.9.2)
7.9.3Floor-mounted compartments are less rigid than the other styles and shall not be used for high-traffic or abuse-prone restrooms.
7.10 Pilaster Shoe
○ Stainless steel, satin finish
○ Powder-coated steel to match (powder-coated systems only)
8 Compartment Dimensions
8.1 Standard Compartment Dimensions
NOTE The values below are typical and serve as datasheet defaults where the drawings do not dictate otherwise. (8.1.1)
3042
30323642
Default: 36 in
5478
5460667278
Default: 60 in
8.2 Pilaster and Door Heights
NOTE The standard panel configuration mounts the panel approximately 12 in. above the finished floor with the panel top approximately 70 in. above the finished floor; floor-to-ceiling and increased-privacy configurations raise the panel top and lower the bottom clearance. (8.2.1)
5582
55586482
Default: 58 in
8.2.2Where increased privacy is required (a common request in schools and public facilities), the panel bottom clearance shall be reduced and the panel and door heights increased as indicated on the drawings.
9 Compartment Hardware
NOTE Hardware is the determinant of long-term durability and privacy performance. (9.1)
9.2Hardware exposed to abuse — hinges, latches, and brackets — shall be of a material and grade matched to the compartment's service condition.
9.3Through-bolted fasteners with tamper-resistant heads should be specified in vandal-prone applications.
9.4 Brackets
NOTE Stirrup (two-ear) brackets are the standard for commercial applications. (9.4.1)
Stirrup (two-ear) brackets at top and bottom of each panel
Full-height continuous bracket (maximum rigidity, vandal-resistant)
Continuous aluminum 'U' channel bracket
○ Stainless steel
○ Aluminum (anodized)
○ Chrome-plated zamac (dry standard commercial only)
9.4.2Full-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.
9.4.3Brackets shall be of the same corrosion class as the compartment hardware.
9.5 Hinges
NOTE 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. (9.5.1)
Gravity (cam) hinge — self-closing, field-adjustable rest position
Spring-action hinge — self-closing, adjustable tension
Continuous (piano) hinge — full door height, high-cycle and abuse-resistant
○ Stainless steel
○ Aluminum (continuous hinge)
○ Chrome-plated zamac (dry standard commercial only)
9.5.2Continuous (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.
9.5.3Accessible compartment doors shall be self-closing per the accessibility requirements below, and the hinge selected for an accessible compartment shall provide reliable self-closing.
9.6 Latch, Strike, and Keeper
Slide latch with strike and keeper (standard)
Slide latch with occupancy indicator (vacant/occupied)
Surface-mounted vandal-resistant latch (heavy gauge, through-bolted)
○ Stainless steel
○ Chrome-plated zamac (dry standard commercial only)
9.6.1The latch shall be mounted with a strike and keeper that doubles as a door stop and rubber bumper to cushion door closing.
9.6.2In vandal-prone applications a heavy-gauge surface-mounted latch with a continuous strike (full-height keeper) shall be specified.
9.6.3Accessible compartment latches shall comply with the operable-hardware requirements of the accessibility section below.
9.7 Coat Hook and Bumper
NOTE The combination coat hook and bumper on the inside face of the door provides a garment hook and prevents the door from striking the panel or the occupant. (9.7.1)
○ Provide combination coat hook and door bumper at each compartment
○ Provide coat hook only
○ Omit (none required)
9.7.2In accessible compartments, a coat hook mounted within the reach ranges of ICC A117.1 shall be provided in addition to any standard-height hook.
9.8 Fasteners
9.8.1Exposed fasteners shall be tamper-resistant (one-way or pin-in-head) stainless steel in vandal-prone applications.
9.8.2Panel-to-pilaster and bracket connections shall be through-bolted, not screwed into the panel face, in high-abuse applications.
10 Urinal Screens
NOTE Urinal screens (also called urinal partitions or dividers) provide privacy between urinals. (10.1)
NOTE A wall-hung screen anchored to gypsum board without blocking will pull loose under normal use. (10.2)
○ Yes — provide urinal screens matching compartment material
○ No — not required at this project
Wall-hung — cantilevered from wall, no floor or ceiling contact
Pilaster-mounted (post to floor) — supported by a floor-anchored post
Post-to-ceiling — supported by a post to overhead structure
Floor-to-ceiling — anchored at floor and ceiling
18 in x 42 in
24 in x 42 in
24 in x 48 in
As indicated on drawings
10.3Urinal screens shall match the compartment material and finish unless otherwise indicated.
10.4The screen mounting type shall be coordinated with the wall construction and the available overhead structure.
10.5Wall-hung urinal screens require solid in-wall blocking at the screen anchorage.
10.6In-wall blocking location and extent shall be coordinated with the wall trade so it is in place before the wall finish is closed.
11 Accessibility Requirements
11.1 Coverage
NOTE This section applies to all toilet compartments required to be accessible under the adopted accessibility standard. (11.1.1)
11.1.2The dimensional requirements throughout this section reflect ICC A117.1-2017 and the 2010 ADA Standards; where the AHJ has adopted a different edition or standard, the adopted requirement shall govern.
NOTE The Architect is responsible for confirming the count and configuration of accessible compartments from the accessibility compliance path. (11.1.3)
11.2 Wheelchair Accessible Compartment Size
5665
56596265
Default: 59 in
○ Wall-hung water closet (56 in. minimum compartment depth)
○ Floor-mounted water closet (59 in. minimum compartment depth)
11.2.1A wheelchair accessible compartment shall be a minimum of 60 in. wide measured perpendicular to the side wall.
11.2.2The width shall increase to 66 in. minimum where the required toe clearance below the side partition is not provided.

11.2.4The compartment depth shall be a minimum of 59 in. for a floor-mounted water closet, measured perpendicular to the rear wall.
11.3 Toe Clearance
NOTE Providing toe clearance allows the smaller minimum compartment dimensions; omitting it requires the larger compartment. (11.3.1)
NOTE Toe clearance is normally provided by the standard panel mounting height of approximately 12 in., which exceeds the 9 in. minimum. (11.3.2)
○ Yes — 9 in. high min, 6 in. deep min below front and side partitions
○ No — compartment width and depth increased accordingly
11.3.3Where toe clearance below the front and one side partition is provided, it shall be a minimum of 9 in. high and 6 in. deep.
11.4 Ambulatory Accessible Compartment
11.4.1Ambulatory accessible compartments are required in addition to wheelchair accessible compartments where the total number of water closets in the restroom reaches the threshold set by the accessibility standard (generally six or more fixtures); the Architect shall confirm the requirement.
○ Yes — required per fixture count threshold
○ No — not required at this restroom
11.4.2An ambulatory accessible compartment shall be a minimum of 35 in. and a maximum of 37 in. wide, and a minimum of 60 in. deep.

11.5.12The latch and pull hardware shall comply with the operable-hardware requirements of ICC A117.1 Section 404.
11.6 Maneuvering Clearance at Accessible Compartment Door
11.6.1The Architect shall confirm the maneuvering clearance at each accessible compartment door on the restroom plan; this clearance is a frequent source of accessibility non-compliance when fixtures or accessories are located within the required clear space.
11.6.2Where the approach to an accessible compartment door is to the latch side, the clearance between the door side of the compartment and the nearest obstruction shall be a minimum of 42 in.
11.7 Accessory Coordination at Accessible Compartments
11.7.1These accessories are furnished and installed under Toilet Accessories, but the compartment shop drawings shall show their locations and the compartment panels shall be reinforced or backed where an accessory mounts to a panel rather than to a wall. ☐ Panel reinforcement for grab bar (where grab bar mounts to panel)
☐ Panel reinforcement for toilet paper dispenser
☐ Accessible-height coat hook within reach range
☐ All accessories mount to walls with in-wall blocking (no panel reinforcement needed)
11.7.2Grab bars, the toilet paper dispenser, the seat-cover dispenser, and the coat hook serving an accessible compartment shall be located within the reach ranges and at the positions required by the accessibility standard.
11.7.3The compartment shop drawings shall show the locations of accessories serving the accessible compartment.
11.7.4The compartment panels shall be reinforced or backed where an accessory mounts to a panel rather than to a wall.
12 Installation
12.1 Coordination and Blocking
NOTE Blocking is furnished and installed under the wall trades. (12.1.1)
○ Yes — blocking verified at all wall anchorage points before installation
○ Not applicable — no wall-anchored components at this restroom
12.1.2Toilet compartments shall be installed after the wall and floor finishes are complete and the building is enclosed and conditioned.
12.1.3The Contractor shall verify before installation that solid in-wall blocking has been provided at every wall-anchored pilaster, panel, urinal screen, and panel-mounted accessory location.
12.1.4The compartment Contractor shall confirm the presence and location of blocking against the shop drawings and shall notify the Architect of any missing or mislocated blocking before proceeding.
12.1.5Anchoring compartments to gypsum board without blocking is a primary cause of premature compartment failure and shall not be permitted.
12.2 Anchorage
NOTE Ceiling-hung pilasters transfer the entire compartment load to the overhead structure. (12.2.1)
12.2.2Pilasters and panels shall be anchored to the building structure and walls with the manufacturer's anchoring devices appropriate to the substrate — expansion or wedge anchors into concrete or masonry, and toggle or through-bolt anchors into blocking within stud walls.
12.2.3Floor anchorage of pilasters shall develop the full design load of the mounting style.
12.2.4Floor-anchored and floor-to-ceiling pilasters shall be leveled and shimmed plumb before the floor anchors are set, and the anchorage shall be concealed by the pilaster shoe.
12.2.5For ceiling-hung and floor-to-ceiling mounting, the overhead structural support shall be verified before installation.
12.2.6Anchoring a ceiling-hung pilaster to an unbraced suspended ceiling grid is not permitted.
12.3 Alignment and Tolerances
○ Plumb within 1/8 in. over full height
○ Project-specified tighter tolerance — see drawings
12.3.1Pilasters shall be installed plumb within 1/8 in. over their full height.
12.3.2Panels shall be installed level, and doors shall be hung so that the gaps at the hinge and latch edges are uniform and the door rests in the intended position when unoccupied.
12.3.3Hardware shall be adjusted so that gravity or spring hinges return the door to its rest position, the latch engages the keeper without binding, and accessible compartment doors close fully and reliably under the self-closing action.
12.4 Adjustment and Cleaning
12.4.1After installation the Contractor shall adjust all hardware for proper operation.
12.4.2After installation the Contractor shall verify that accessible compartment doors are self-closing and that all clearances meet the accessibility requirements.
12.4.3After installation the Contractor shall clean all surfaces with the cleaning method appropriate to the compartment material.
12.4.4Protective coverings shall remain in place until adjustment and cleaning are complete.
12.4.5Damaged, scratched, or corroded components shall be replaced, not field-repaired.
13 Warranty
13.1Solid plastic and solid phenolic materials carry substantially longer manufacturer warranties than laminate or steel because they do not delaminate or corrode; where the project uses solid plastic or phenolic, the longer material warranty should be obtained and documented.
1 year from substantial completion — standard
3 years from substantial completion
