1 Scope
NOTE This standard covers the furnishing and installation of toilet and bath accessories in commercial, institutional, and light-industrial buildings. (1.1)
NOTE The scope includes washroom accessories of all mounting types — surface-mounted, recessed, and semi-recessed — and the structural backing, blocking, and fire-rated wall coordination required to support them. (1.2)
1.3Accessory types, quantities, locations, and mounting heights for each toilet room shall be as indicated on the contract drawings and accessory schedule.
1.4This standard establishes the minimum material, finish, accessibility, structural, and installation requirements that apply to all of those conditions.
NOTE Toilet accessories are deceptively simple products that carry disproportionate compliance risk — a misplaced grab bar, a mirror mounted an inch too high, a dispenser outside the reach range, or a recessed unit that breaches a fire-rated wall without an approved firestop are among the most common accessibility and life-safety deficiencies found at building inspection, and the wall blocking that supports a 250 lbf grab bar must be installed during rough framing, long before the accessory itself arrives. (1.5)
1.6The Contractor shall coordinate accessory locations, blocking, and fire-rated wall penetrations early.
1.7The Contractor shall treat the accessory and its backing as a single system.
1.8The Contractor shall verify every accessible-fixture mounting dimension against the adopted accessibility standard before installation.
1.9This work shall be coordinated with Toilet Compartments for partition-mounted accessories and grab bars anchored to pilasters or compartment walls, with Gypsum Board Assemblies for in-wall blocking, backing plates, and recessed-unit framing, and with Firestopping where recessed accessories penetrate fire-resistance-rated walls. 2 Referenced Standards
2.1Materials, fabrication, and installation shall comply with the latest adopted edition of the referenced standards.
2.2Where the contract documents or the adopted building and accessibility codes impose more stringent requirements than a referenced standard, the more stringent requirement shall govern.
2.3The Contractor shall resolve conflicts in writing with the Architect before proceeding.

4 Quality Assurance
4.1 Single-Source Responsibility
○ Single manufacturer for all accessories except grab bars and baby-changing stations
○ Single manufacturer for all accessories including grab bars
○ Multiple manufacturers permitted — match finish across all accessories
4.1.1Accessories should be furnished from a single manufacturer to the greatest extent practical so that finish, material, and visual appearance are consistent within each toilet room and across the building.
4.1.2Grab bars and baby-changing stations may be excepted from single-source supply provided their finish is coordinated to match the balance of the accessories.
4.1.3Where multiple manufacturers are used, the Contractor shall confirm that the satin stainless finish is visually consistent across all products.
4.2 Mounting Height Verification
4.2.1The Contractor shall verify, before installation, that the mounting height of every accessory serving an accessible fixture complies with ICC A117.1-2017 and the ADA 2010 Standards for the controlling reference point of that accessory.
4.2.2The Contractor shall not rely on standard rough-in heights alone but shall confirm each dimension against the adopted accessibility standard and the accessory schedule.
NOTE Accessory mounting is one of the most frequently cited accessibility deficiencies. (4.2.3)
4.3 Accessibility Standard Governing the Project
ICC A117.1-2017 and ADA 2010 — both apply, more stringent governs
ICC A117.1-2017 only (per adopted building code)
ADA 2010 Standards only
Local amended accessibility standard — see drawings
NOTE Most commercial projects must satisfy both the federal ADA 2010 Standards and the locally adopted accessibility provisions of ICC A117.1, which are largely harmonized but differ in some dimensions. (4.3.1)
4.3.2Where the two standards differ, the more stringent requirement shall govern unless the Authority Having Jurisdiction directs otherwise.
4.3.3The Architect shall identify the governing standard and the accessible fixtures on the drawings.
5 Materials and Finishes
5.1 Primary Material — Stainless Steel
NOTE The dominant material for commercial toilet accessories is austenitic stainless steel because it resists the corrosion, abrasion, cleaning chemicals, and vandalism encountered in public washrooms. (5.1.1)
Type 304 stainless steel (ASTM A666) — standard commercial
Type 316 stainless steel — coastal, high-chloride, or marine environments
Chrome-plated brass or zinc — limited decorative or budget applications
Molded plastic / polymer — budget or specific specialty units
5.1.2Type 304 stainless steel conforming to ASTM A666 shall be the standard material for accessory bodies, doors, flanges, and exposed surfaces.
5.1.3Type 316 stainless steel, which contains molybdenum for greater chloride resistance, should be specified for coastal locations, natatoriums, and other high-chloride or aggressively corrosive environments where Type 304 may exhibit pitting.
NOTE Chrome-plated brass and zinc are limited to decorative applications or budget projects and do not match the durability of stainless steel in high-traffic public washrooms. (5.1.4)
5.1.5Molded polymer units are used for specific products (such as some seat-cover dispensers and waste receptacle liners) but should not be the default body material in public installations subject to vandalism.
5.2 Stainless Steel Finish
○ Satin (No. 4 brushed) — standard, hides fingerprints and minor scratches
○ Bright polished (No. 8 mirror) — decorative, shows fingerprints and wear
○ Matte black or color-coated stainless — designer specification
5.2.1A satin (No. 4 brushed) finish shall be the standard for commercial toilet accessories because it conceals fingerprints, water spotting, and minor surface scratches and requires less maintenance over the life of the installation.
5.2.2Bright polished (No. 8 mirror) finish is a decorative selection used where a higher-end appearance is desired, but it shows wear and fingerprints readily and is not recommended for high-traffic public restrooms.
5.2.3Color-coated and matte black stainless finishes are designer selections that should be confirmed for availability and durability of the coating before specification.
5.3 Sheet Gauge
22 gauge — light-duty surface units (dispensers, holders)
20 gauge — standard exposed bodies and flanges
18 gauge — doors, shelves, and high-abuse surfaces
16 gauge — heavy-duty or vandal-resistant applications
5.3.1The exposed bodies, flanges, and cover plates of standard accessories shall be fabricated from not less than 20 gauge stainless steel.
5.3.2Doors, shelves, and surfaces subject to bending or abuse shall be not less than 18 gauge.
5.3.3Heavy-duty or vandal-resistant installations (detention-adjacent, high-abuse public facilities, transit) shall use 16 gauge or thicker as scheduled.
5.4 Mirror Glass
Silvered float glass mirror (ASTM C1503), 1/4 in., framed in stainless
No. 8 polished stainless steel mirror — vandal-resistant, no glass
Laminated safety mirror glass — high-occupancy or impact-prone areas
5.4.1Standard washroom mirrors shall be 1/4 in. silvered float glass conforming to ASTM C1503, set in a stainless steel channel frame with a galvanized steel back and a protective backing coating to resist corrosion of the silvering at the edges.
5.4.2Polished stainless steel mirrors (No. 8 finish, no glass) shall be specified where vandal resistance or impact safety is the priority, such as detention-adjacent toilet rooms or facilities with a history of glass breakage.
5.4.3Laminated safety mirror glass should be considered in high-occupancy or impact-prone areas where a framed glass mirror is desired but breakage risk is elevated.
5.5 Vandal Resistance
○ Standard commercial construction
○ Vandal-resistant — heavy gauge, tamper-resistant fasteners, theft-resistant locks
5.5.1Vandal-resistant construction — heavier gauge bodies, security (tamper-resistant) fasteners, concealed mounting, and theft-resistant tumbler locks on dispensers — shall be specified for public facilities, schools, transit stations, parks, and any location with a history of vandalism.
5.5.2Standard commercial construction is appropriate for offices, healthcare, and other controlled-access environments.
6 Accessory Schedule by Type
NOTE The accessory schedule and the interior elevations determine which accessories are furnished in each toilet room and where they are located. (6.1)
NOTE The selections below establish the type and configuration of each accessory category where it occurs. (6.2)
6.4 Mounting Type
○ Surface-mounted — fastened to the finished wall face
○ Recessed — set into a wall opening, flange flush with wall
○ Semi-recessed — partially recessed, body projects from wall
NOTE Surface-mounted accessories are the default and are appropriate for most applications. (6.4.1)
NOTE Recessed accessories provide a cleaner appearance and reduce protrusion into the room but require a wall opening, framing coordination, and — in fire-rated and plumbing walls — additional coordination as described below. (6.4.2)
NOTE Semi-recessed units are a compromise used where the wall depth is insufficient for full recessing but a reduced projection is desired. (6.4.3)
6.4.4The mounting type shall be coordinated with the wall construction and confirmed before rough framing is closed, because recessed and semi-recessed units cannot be accommodated after the wall is finished without demolition.
6.5 Grab Bars
6.5.1Grab bars shall conform to ASTM F446 and shall be Type 304 stainless steel with a peened (slip-resistant) or satin gripping surface.
6.5.3 Grab Bar Outside Diameter
1.252
1.251.51.752
Default: 1.5 in
6.5.3.1The outside diameter of a circular grab bar shall be 1-1/4 in. minimum and 2 in. maximum per ICC A117.1-2017 Section 609.2.1; a 1-1/2 in. diameter is the most common commercial selection and is the default.
6.5.3.2Non-circular grab bars shall comply with the perimeter dimension and cross-section limits of Section 609.2.2.
6.5.4 Grab Bar Clearance from Wall
1.52
1.51.752
Default: 1.5 in
6.5.4.1The clearance between a grab bar and the wall behind it shall be 1-1/2 in. per ICC A117.1-2017 Section 609.3.
NOTE This clearance is a fixed accessibility requirement, not a tolerance — a clearance smaller than 1-1/2 in. traps the forearm, and a larger clearance allows the arm to slip behind the bar. (6.5.4.2)
6.5.4.3The grab bar mounting brackets shall hold the bar at exactly this clearance.
6.5.5 Grab Bar Structural Load Resistance
○ 250 lbf minimum in any direction (ICC A117.1 609.8 / ASTM F446)
○ Higher — as required by drawings for bariatric or specialty fixtures
6.5.5.1The grab bar, its mounting brackets, the fasteners, and the wall backing shall together resist a concentrated load of 250 lbf applied in any direction at any point on the bar, per ICC A117.1-2017 Section 609.8 and ASTM F446.
NOTE A grab bar fastened only into gypsum board or into a wall anchor without solid backing will not develop the required 250 lbf resistance regardless of the bar's own strength; the wall blocking, the backing plate, and the fasteners into solid backing are what carry the load. (6.5.5.2)
6.5.5.3The required backing shall be installed during rough framing as described in the Installation section.
6.5.6 Grab Bar Mounting Height — Horizontal Bars at Water Closet
3336
33343536
Default: 33 in AFF
6.5.6.1Horizontal grab bars at a water closet shall be mounted with the top of the gripping surface 33 in. to 36 in. above the finished floor per ICC A117.1-2017 Section 604.5, and all horizontal bars in a given toilet room should be mounted at a consistent height within this range.
6.5.6.2The rear-wall grab bar shall be 36 in. long minimum, and the side-wall grab bar shall be 42 in. long minimum, located 12 in. maximum from the rear wall, per Sections 604.5.1 and 604.5.2.
6.5.7 Vertical Grab Bar at Side Wall
○ Yes — 18 in. minimum vertical bar, bottom 39 in.–41 in. AFF (ICC A117.1-2017)
○ No — not required by governing standard
6.5.7.1ICC A117.1-2017 Section 604.5.1 requires a vertical grab bar 18 in. minimum in length on the side wall, mounted above the horizontal side bar with the bottom of the bar 39 in. to 41 in. above the finished floor.
NOTE The vertical bar aids ambulatory users transitioning to and from a standing position and is required for new construction under the 2017 edition even though it is not required by the ADA 2010 Standards. (6.5.7.2)
6.5.7.3Where both standards apply, the vertical bar shall be provided.
6.6 Mirrors
6.6.2Mirrors at accessible lavatories shall be mounted in compliance with the reflecting-surface height requirement below.
6.6.3 Mirror Bottom Edge Height — Accessible Lavatory
3540
353840
Default: 40 in AFF
6.6.3.1At an accessible lavatory or countertop, the bottom edge of the reflecting surface of a mirror shall be 40 in. maximum above the finished floor per ICC A117.1-2017 Section 603.3.
6.6.3.2Where a full-length mirror or a mirror not located above a lavatory is provided, the bottom edge of the reflecting surface shall be 35 in. maximum above the floor.
6.6.3.3The 40 in. dimension is measured to the reflecting surface, not to the frame; the Contractor shall account for the frame when setting the mounting height.
6.7 Paper Towel Dispensers and Combination Units
Surface-mounted folded/roll towel dispenser
Recessed towel dispenser
Recessed combination towel dispenser / waste receptacle
Automatic (sensor) roll towel dispenser
Not provided — electric hand dryer specified instead
NOTE The recessed combination towel dispenser and waste receptacle is the most common configuration in commercial washrooms because it consolidates two functions in one recessed unit and keeps the waste receptacle off the floor. (6.7.1)
6.7.2Where hand drying is provided by electric hand dryers, paper towel dispensers may be omitted, and the Architect shall confirm the hand-drying method.
NOTE Automatic sensor dispensers reduce touch points and waste and are common in healthcare and high-traffic facilities. (6.7.3)
6.7.4 Towel Dispenser Operable Part Height
1548
404248
Default: 40 in AFF
6.7.4.1The operable part (the dispensing point) of a paper towel dispenser serving an accessible route shall be located within the reach range of 15 in. minimum to 48 in. maximum above the finished floor per ICC A117.1-2017 Section 308, and the dispenser shall be reachable from the clear floor space at the accessible lavatory.
NOTE A dispensing height of approximately 40 in. is the practical commercial default that serves both standing and seated users. (6.7.4.2)
6.7.4.3The dispenser shall not be located such that it forces a reach over an obstruction beyond the allowable reach depth.
6.8 Soap Dispensers
Surface-mounted manual soap dispenser
Deck-mounted (lavatory or counter) soap dispenser
Automatic (sensor) soap dispenser
Recessed soap dispenser
1548
404448
Default: 44 in AFF
6.8.1The operable part of a soap dispenser serving an accessible lavatory shall be within the reach range of 15 in. to 48 in. above the finished floor and within the allowable reach depth from the accessible clear floor space, per ICC A117.1-2017 Section 308.
6.8.2Where the dispenser is mounted on the wall behind the lavatory, the Contractor shall confirm the obstructed reach geometry and shall not assume the unobstructed 48 in. maximum applies where the user must reach over the lavatory.
6.9 Sanitary-Napkin Dispensers and Disposals
○ Yes — vending (coin/free) sanitary-napkin dispenser
○ No — disposal only
Surface-mounted disposal at each accessible and standard compartment
Recessed disposal
Combination napkin disposal integrated with toilet-paper holder
Partition-mounted disposal (between compartments)
6.9.1A sanitary-napkin disposal shall be provided in every toilet compartment in a women's or unisex toilet room, including each accessible compartment.
6.9.2The disposal at an accessible compartment shall be positioned so that its operable part is within reach from the accessible water closet clear floor space and does not obstruct the required clear floor space or the grab bars.
6.9.3The operable part shall be within the reach range of 15 in. to 48 in. above the finished floor.
6.10 Waste Receptacles
Recessed (integral with towel dispenser) waste receptacle
Surface-mounted waste receptacle
Semi-recessed waste receptacle
Free-standing receptacle (not in this scope)
NOTE Wall-mounted or recessed waste receptacles are preferred over free-standing receptacles in accessible toilet rooms because a free-standing receptacle is a movable obstruction that can be placed within the required clear floor space or maneuvering clearance. (6.10.1)
6.10.2Where a recessed combination towel-dispenser/receptacle is used, a separate waste receptacle may not be required.
6.10.3Receptacle capacity shall be appropriate for the fixture count and traffic of the toilet room.
6.11 Toilet-Paper Holders
Surface-mounted double-roll holder
Recessed double-roll holder
Partition-mounted holder (between compartments)
Multi-roll / jumbo-roll dispenser
Combination holder with sanitary-napkin disposal
6.11.1 Toilet-Paper Dispenser Position from Water Closet — Accessible
6.11.1.1At an accessible water closet, the toilet-paper dispenser shall be located 7 in. minimum and 9 in. maximum in front of the water closet, measured to the centerline of the dispenser, per ICC A117.1-2017 Section 604.7.
6.11.1.2The outlet of the dispenser shall be 15 in. minimum and 48 in. maximum above the finished floor, and the dispenser shall not be located behind the side grab bar in a way that obstructs the bar or interferes with reach.
6.11.1.3Dispensers that control delivery (those that do not allow continuous paper flow) are not permitted at accessible water closets; the dispenser shall allow continuous paper delivery.
6.12 Seat-Cover Dispensers
○ Yes — one per compartment
○ Yes — combination seat-cover / toilet-paper unit
○ No
6.12.1Where seat-cover dispensers are provided, the operable part shall be within the reach range of 15 in. to 48 in. above the finished floor at accessible compartments and shall be positioned so as not to obstruct the clear floor space or grab bars.
6.13 Baby-Changing Stations
○ Yes — horizontal fold-down changing station
○ Yes — vertical fold-down changing station
○ No
6.13.1Baby-changing stations (diaper-changing tables) for commercial and public installation shall comply with ASTM F2285, the consumer safety performance specification for diaper changing tables for commercial use.
NOTE ASTM F2388 governs domestic-use products and applies to consumer changing products, not to fixed commercial restroom units; it is referenced here only to distinguish the two. (6.13.2)
6.13.3The station shall include an integral child-restraint strap and shall be labeled with weight capacity and safe-use instructions per ASTM F2285.
6.13.4 Baby-Changing Station Open-Surface Height
2834
283034
Default: 34 in AFF
6.13.4.1Where a baby-changing station is located on an accessible route, the changing surface in the open (deployed) position shall be a usable height, and the operable parts (the latch and release used to lower and raise the unit) shall be within the reach range of 15 in. to 48 in. above the finished floor.
6.13.4.2When folded closed, the station shall not project from the wall more than 4 in. into the circulation path between 27 in. and 80 in. above the floor, to comply with the protruding-object limits of ICC A117.1-2017 Section 307.
6.13.4.3Where a unit projects more than 4 in. in the closed position, it shall be recessed or located outside the accessible circulation path.
6.14 Robe Hooks and Coat Hooks
○ Yes — one hook per compartment
○ Yes — hook plus bumper, surface-mounted
○ No
6.14.1 Coat Hook Mounting Height — Accessible Compartment
4048
4448
Default: 48 in AFF
6.14.1.1A coat hook within an accessible toilet compartment shall be mounted no higher than 48 in. above the finished floor so that it is within the reach range per ICC A117.1-2017 Section 308.
6.14.1.2Coat hooks projecting from the wall shall not project more than 4 in. into the circulation path between 27 in. and 80 in. above the floor per the protruding-object limits of Section 307.
6.14.1.3Hooks that project farther shall be located outside the accessible circulation path or recessed.
6.15 Shelves and Utility Accessories
○ Yes — stainless steel utility shelf
○ No
6.15.1Where shelves are provided, they shall be Type 304 stainless steel, fabricated of not less than 18 gauge with formed and returned edges to remove sharp corners, and securely anchored to wall backing.
6.15.2A shelf shall not project more than 4 in. into the accessible circulation path where it is located between 27 in. and 80 in. above the floor unless it is outside that path.
7 Accessibility and Mounting
7.1 Reach Ranges — General
○ Unobstructed reach — 15 in. to 48 in. AFF
○ Obstructed reach (over lavatory/counter) — reduced maximum per depth of obstruction
7.1.1All operable parts of accessories serving an accessible route — dispensing points, latches, levers, and controls — shall be located within the reach ranges established by ICC A117.1-2017 Section 308 and the ADA 2010 Standards.
7.1.2For an unobstructed forward or side reach, the operable part shall be 15 in. minimum and 48 in. maximum above the finished floor.
7.1.3Where the reach is over an obstruction (such as a lavatory or counter), the maximum reach height is reduced based on the depth of the obstruction, and the Contractor shall confirm the obstructed-reach geometry for any accessory mounted above or behind a fixture.
7.2 Protruding Objects
Recess units in circulation paths to limit projection to 4 in. maximum
Locate surface-mounted units outside the accessible circulation path
Surface-mount permitted — units do not encroach the 27 in.–80 in. zone in any path
7.2.1Wall-mounted accessories that project from the wall — surface-mounted dispensers, fold-down baby-changing stations, robe hooks, shelves, and surface-mounted grab bars at their brackets — shall comply with the protruding-object limits of ICC A117.1-2017 Section 307 and the ADA 2010 Standards.
7.2.2Objects with leading edges between 27 in. and 80 in. above the floor shall not protrude more than 4 in. into the circulation path.
NOTE A surface-mounted soap dispenser or towel dispenser mounted in a corridor or in the path between the door and the lavatory frequently violates the 4 in. limit and is one of the most common accessory deficiencies. (7.2.3)
7.2.4Where an accessory would protrude more than 4 in. in that height zone, it shall be recessed, relocated outside the circulation path, or mounted with its leading edge below 27 in. or above 80 in.
7.3 Coordination of Accessible Compartment Accessories
7.3.1In an accessible water closet compartment, the toilet-paper dispenser, the sanitary-napkin disposal, the coat hook, and the grab bars shall all be located so that no accessory obstructs another, none obstructs the required clear floor space or transfer space, and each operable part remains within reach.
7.3.2The interior elevations shall show the coordinated layout of all compartment accessories together.
7.3.3The Contractor shall not locate accessories individually without reference to the coordinated elevation, because an individually placed disposal or dispenser commonly ends up behind or below a grab bar where it cannot be reached.
8 Installation and Blocking Coordination
8.1 In-Wall Blocking and Backing
NOTE The structural performance of wall-mounted accessories — and grab bars in particular — depends entirely on the in-wall blocking and backing installed during rough framing, long before the accessory is mounted. (8.1.1)
8.1.2The Contractor shall install solid backing for every wall-mounted accessory at the locations shown on the accessory schedule and interior elevations, coordinated with Gypsum Board Assemblies. 8.1.3Backing shall be installed and its locations documented before the gypsum board is closed.
NOTE Accessories that arrive after the wall is finished cannot develop their required load capacity if backing was omitted. (8.1.4)
8.1.5 Grab Bar Backing
Continuous steel backing plate behind the finish at grab bar locations
Solid wood blocking between studs at grab bar locations
Manufactured grab bar mounting plate / fastener system into solid framing
8.1.5.1Grab bars shall be anchored to a continuous steel backing plate or to solid wood blocking installed between the studs at the grab bar height and extending the full length of the bar plus the bracket spread.
8.1.5.2The backing and fasteners shall together resist the 250 lbf load required by ICC A117.1-2017 Section 609.8 in any direction at any point.
8.1.5.3Toggle anchors, plastic anchors, and fasteners into gypsum board alone shall not be used to mount grab bars under any circumstance.
8.1.5.4Where a grab bar is mounted to a toilet compartment pilaster or panel rather than a wall, coordinate the reinforcement with Toilet Compartments so that the panel or pilaster is internally reinforced to carry the load. 8.1.6 Surface-Mounted Accessory Backing
○ Solid blocking or backing plate at each surface-mounted accessory
○ Manufacturer's anchors into solid framing only (no gypsum-only anchors)
8.1.6.1Surface-mounted dispensers, holders, mirrors, and shelves shall be anchored to solid blocking or a backing plate at each unit, or to solid framing using the manufacturer's recommended anchors.
8.1.6.2Fasteners into gypsum board alone are not acceptable for any accessory that bears weight, is subject to pulling, or could be vandalized.
8.2 Recessed Units in Standard Walls
8.2.1Recessed and semi-recessed accessories require a framed wall opening of the dimensions shown in the manufacturer's product data.
8.2.2The Contractor shall frame the rough opening during wall framing, confirm the unit's required wall depth against the actual wall cavity depth, and verify that the recessed unit does not conflict with plumbing, conduit, structural studs, or backing for adjacent accessories.
8.2.3Recessed units shall be set flush and plumb, with the flange tight to the finished wall surface and sealed where required to prevent moisture migration into the wall cavity.
8.3 Recessed Units in Fire-Rated Walls
Membrane-penetration firestop system (ASTM E814 / UL 1479) per listed design
Listed fire-rated protective enclosure / backing box behind the recessed unit
Asymmetric rated wall assembly designed for one-side penetration
Not applicable — recessed unit is not in a fire-rated wall
8.3.1Where a recessed accessory penetrates a fire-resistance-rated wall, the membrane penetration created by the recessed unit shall be protected so that the required fire-resistance rating of the wall is maintained, in accordance with IBC Chapter 7.
8.3.2A recessed accessory in a rated wall is a membrane penetration and shall be protected by an approved membrane-penetration firestop system tested to ASTM E814 or UL 1479, by a listed protective enclosure (such as a fire-rated backing box or mineral-wool wrap installed per a listed design), or by installing the unit in an asymmetric/unbalanced wall assembly designed to permit one-side penetration.
8.3.3The firestop system or protective enclosure shall be coordinated with Firestopping. 8.3.4The Contractor shall not cut a recessed opening into a fire-rated wall without an approved protection method in hand.
8.3.5The protection method shall be submitted and approved before the rated wall is penetrated.
NOTE Cutting a rated wall and installing an unprotected recessed accessory breaches the fire-resistance rating of the wall and is a code violation that is expensive to correct after finishes are complete. (8.3.6)
8.4 Recessed Units in Plumbing Walls
8.4.1Recessed accessories on a wet wall shall be coordinated with the plumbing rough-in so that the recessed unit does not conflict with supply piping, waste piping, vent stacks, carriers, or in-wall flush valves and tanks.
8.4.2The Contractor shall confirm the wall cavity depth and the location of plumbing before framing the recessed opening, because a recessed unit and a fixture carrier competing for the same wall cavity is a common and avoidable field conflict.
8.5 Mounting Height Field Verification
○ Required — verify and obtain approval at one representative room before proceeding
○ Not required — Contractor verifies each room against the schedule
8.5.1Before installation, the Contractor shall lay out the mounting height of every accessory and shall verify each accessible-fixture height against the governing accessibility standard and the accessory schedule.
8.5.2The Architect or the Owner's accessibility reviewer may require verification of mounting heights at a representative toilet room before the balance of the accessories are installed.
8.6 Cleaning and Protection
8.6.1Accessories shall be protected from damage and from construction dust and overspray until substantial completion.
8.6.2Protective films and packaging shall remain on stainless surfaces and mirrors until final cleaning.
8.6.3At completion, stainless surfaces shall be cleaned per the manufacturer's instructions with non-abrasive cleaners only; abrasive cleaners and steel wool shall not be used on stainless steel, as they scratch the finish and embed carbon steel particles that later rust.
