Stainless Steel Bathroom Stalls for Public Restrooms: A Specification Guide

Public restroom toilet compartment

A toilet compartment in a public restroom is an enclosed space formed by partitions and a door, coordinated with the water closet, required clearances and the route through the restroom.

How to Plan Toilet Stalls in Public Restrooms

A public restroom stall is a toilet compartment formed by partitions and a door. Its position must work with the water closet, accessible clearances, door approach, grab bars, other fixtures and cleaning access. Establish whether the facility is a multi-user restroom, how many toilets and urinals it contains, who uses it and which local rules apply. Specify the stall as part of the restroom plan, with its fixtures and circulation shown together.

Set the Compartment Layout Before Selecting Finishes

In a shared restroom, partitions, door swings, water closets, sinks and circulation use the same floor area. Place each fixture and compartment on one plan, then check required clearances and the routes for entry, transfer and exit. Include the cleaning path to the compartment floor and both faces of each door. Resolve the layout before selecting panel color or hardware; a finish cannot correct a blocked route or a door that conflicts with another fixture.

Wheelchair-Accessible Compartment Dimensions

Where toilet compartments are provided in a facility subject to the U.S. ADA Standards, at least one must be wheelchair accessible. Under ADA 604.8.1.1, it must be 60 inches, or 1525 millimeters, wide measured perpendicular to the side wall. Minimum depth is 56 inches, or 1420 millimeters, for a wall-hung water closet and 59 inches, or 1500 millimeters, for a floor-mounted water closet, measured perpendicular to the rear wall. The same chapter notes that a compartment without toe space below the partitions needs more depth. If a lavatory or another plumbing fixture is placed inside the stall, the compartment must meet the larger single-user toilet-room rules, including turning space, and another compliant lavatory is still required outside. Keep the selected water-closet type on the same drawing as the stall depth so the 56-inch and 59-inch rules are not mixed.

When Is an Ambulatory-Accessible Compartment Required?

A wheelchair-accessible stall is not the only accessible compartment in a larger washroom. ADA 213.3.1 requires an ambulatory-accessible compartment in addition to the wheelchair stall where 6 or more toilet compartments are provided, or where urinals and water closets together total 6 or more fixtures. ADA 604.8.2.1 sets that compartment at 60 inches, or 1525 millimeters, deep minimum, and 35 inches to 37 inches, or 890 to 940 millimeters, wide. The Access Board explains that ambulatory compartments help people who walk with canes, crutches or similar support and need parallel grab bars to sit or stand. They do not replace the wheelchair stall and do not accommodate a wheelchair or scooter. A narrow 36-inch-class enclosure with support on both sides serves a different access need from a 60-inch wheelchair stall. Show the toilet and urinal count on the restroom plan to identify whether the six-fixture trigger applies.

Door Location, Operation and Clearance

ADA 604.8.1.2 places the compartment door in the front partition or in the side wall farthest from the water closet. If the door is in the front, the opening sits 4 inches, or 100 millimeters, maximum from the side farthest from the water closet. If the door is in the side, the opening sits 4 inches maximum from the front partition. The door must be self-closing. A pull is required on both sides near the latch. The door cannot swing into the minimum required compartment area. On a latch-side approach, clearance between the door side of the compartment and any obstruction is 42 inches, or 1065 millimeters, minimum. Those rules give a person using a mobility aid space to open the door, enter and let the door close without trapping a chair against the bowl. Show the stall door swing and the latch-side approach clearance on the same drawing as the neighboring restroom fixtures.

Toe Clearance and Full-Height Partitions

ADA 604.8.1.4 requires the front partition and at least one side partition to provide toe clearance of 9 inches, or 230 millimeters, minimum above the finished floor and 6 inches, or 150 millimeters, deep beyond the compartment-side face of the partition, not counting support members. Compartments designed for children 12 and younger need 12 inches, or 305 millimeters, of height so higher footrests can pass. The Access Board notes that full-height walls are allowed, but then the stall must grow because the missing toe space is no longer available. The written exceptions are specific. Front toe clearance is not required in a compartment deeper than 62 inches, or 1575 millimeters, with a wall-hung water closet, or deeper than 65 inches, or 1650 millimeters, with a floor-mounted water closet. Side toe clearance is not required in a compartment wider than 66 inches. Vertical supports may sit inside the toe zone; the standards do not cap their width. Show either the required toe space or the dimensions of the applicable enlarged compartment on the stall schedule.

Coordinate Stall Clearances with the Restroom Plan

Plan public and shared restrooms around the actual users, fixture count, circulation and maintenance needs. Keep wheelchair-accessible and ambulatory compartments where required, and coordinate their doors with sinks, plumbing fixtures, dispensers and the entry route. Where a lavatory or another plumbing fixture is inside a compartment, include the requirements for a single-user toilet room in the plan. A qualified professional should review the drawing against the requirements adopted for the facility.

Specify Partition Materials and Cleaning

SSINA describes stainless steel as an iron-based alloy family containing at least 10.5 percent chromium. For Type 304, it lists 18 to 20 percent chromium and 8 to 10.5 percent nickel; match the specified panel grade to the supplied material certificate. SSINA warns that muriatic (hydrochloric) acid is highly corrosive to architectural stainless steel: fumes in an enclosed room can also cause surface corrosion without direct contact. Keep it away during nearby tile or masonry cleaning, and specify a cleaner approved for the exact panel finish. Include the finish and cleaning instructions in the restroom maintenance file.

Keep Other Fixtures Outside Required Clearances

A sink, storage unit or other fixture must not intrude into the clearances required for a compartment or its door. If a plumbing fixture is located inside a compartment, additional toilet-room requirements apply under ADA 603. Coordinate the partition, water closet, grab bars, dispensers and nearby fixtures on the same drawing, then have the responsible professional confirm the arrangement.

Verify the Layout on Site

Before fabrication, confirm the finished compartment width and depth, the selected water-closet type, fixture count, door swing, grab bars and the clear route around each stall. ADA 604.8.3 places shelves between 40 and 48 inches, or 1015 and 1220 millimeters, above the floor; hooks must fall within the reach ranges in section 308. Check the finished floor slope, drain location and approved cleaning products against the partition supplier’s instructions. The Access Board guide explains the federal ADA Standards; the responsible local professional should also check the code adopted for the facility.

Retain the Specification and Handover Records

Keep the approved restroom plan, stall and water-closet model sheets, partition material and finish schedule, hardware, installation record, care instructions and local review together. Record measured dimensions and the responsible maintenance contact. Before a renovation moves a fixture or adds a stall, recheck the plan because the updated layout may change required clearances or the accessible-compartment count.
