The ADA (Americans with Disabilities Act) outlines specific requirements for toilet rooms to ensure accessibility for individuals with disabilities. These standards cover various aspects, including doorways, clear floor space, toilet stalls, sinks, and grab bars. While plumbing and building codes dictate the number and type of toilet rooms needed, ADA standards focus on making those toilet rooms accessible. This includes specifications for unisex toilet rooms, which should have privacy latches and contain specific fixtures. Grab bars, for instance, are essential for providing support and stability for people with motor disabilities. ADA compliance is mandatory for commercial facilities and hotels, ensuring that disabled individuals can comfortably utilize these spaces.

What You'll Learn
Unisex toilet rooms
The U.S. Access Board is a federal agency that promotes equality for people with disabilities through accessible design and the development of accessibility guidelines and standards for the built environment, transportation, communication, medical diagnostic equipment, and information technology. The ADA Standards specify which toilet rooms must be accessible, but they do not address the number of toilet rooms or fixtures required for a facility.
The International Building Code (IBC) requires accessible unisex or "family" toilet rooms in assembly and mercantile occupancies where a total of six or more toilet fixtures are required. In new construction, ADA accessibility is required for all toilet rooms, including employee restrooms.
Some additional design considerations for ADA-compliant toilet rooms include ensuring that exposed pipes are insulated or configured to prevent contact and that there is sufficient clear floor space beyond the arc of the door to allow for the door swing.

Dimensions and Measurements
The ADA guidelines specify the dimensions for clear floor space. For a single-user toilet room, a minimum clear floor space of 30 inches by 48 inches is required in the room beyond the arc of the door swing. This ensures that a wheelchair user can comfortably navigate through the doorway and have sufficient space inside the toilet room.
Door Swing Considerations
The door swing is an important factor in maintaining clear floor space. The ADA allows the door swing to overlap with the clearance of fixtures such as the lavatory and water closet, as long as the specified minimum clear floor space of 30 inches by 48 inches is maintained beyond the arc of the door swing. This provision offers flexibility in the layout of the toilet room while still ensuring adequate space for wheelchair users.
Grab Bars and Fixtures
Grab bars and other fixtures must be installed in a way that does not obstruct the clear floor space. While grab bars are essential for safety, they should be positioned to avoid impeding the manoeuvrability of wheelchairs. Folding or swing-away grab bars are permitted as long as they do not interfere with the required clear floor space and are properly secured.
Baby Changing Stations
In the presence of a baby changing station, the clear floor space requirements may vary slightly. The clear floor space for the baby changing station can overlap with the clearance at the water closet, as long as the table, when fully opened, remains outside of the water closet clearance. This ensures that individuals using wheelchairs can still access the changing station while maintaining adequate space.
By adhering to these clear floor space guidelines, designers and architects can create toilet rooms that are accessible and inclusive for all individuals, including those who use wheelchairs or have other mobility needs.

Toilet stalls
In single-user toilet rooms, the ADA Standards require a clear floor space of at least 30" (760 mm) by 48" (1220 mm) beyond the arc of the door swing. This allows for adequate manoeuvrability for individuals using the space. Exposed pipes must also be insulated or configured to prevent accidental contact, creating a safer environment.
For multiple-user toilet rooms, the ADA Standards focus on providing accessible unisex toilet stalls or compartments. These stalls should include privacy latches and contain a maximum of one lavatory, one water closet, and one urinal (or an additional water closet). This ensures that individuals with disabilities have equal access to facilities and privacy while using the restroom.
It's important to note that the ADA Standards do not specify the number of toilet rooms or fixtures required for a facility. Instead, they outline which fixtures must be accessible when provided. Additionally, exceptions and alterations exist for certain types of buildings, such as historic structures, where providing full ADA-compliant toilet stalls may not be feasible.

Grab bars
The specifications for grab bars, as outlined by the ADA Standards and other guidelines, are as follows:
- A minimum length of 36 inches (915 mm) for the rear wall grab bar, mounted 33-36 inches (840-915 mm) above the finished floor. This bar must extend at least 12 inches (305 mm) from the centerline of the water closet toward the sidewall and a minimum of 24 inches (610 mm) from the centerline toward the open side.
- In cases where wall space constraints do not permit a 36-inch grab bar, a rear wall grab bar with a minimum length of 24 inches (610 mm) can be installed, centered on the water closet.
- A minimum length of 42 inches (1065 mm) for the sidewall grab bar, positioned a maximum of 12 inches (305 mm) from the back wall. This bar should extend a minimum of 54 inches (1370 mm) from the back wall and be placed at a height of 33-36 inches (840-915 mm).
- The toilet paper dispenser should be mounted below the sidewall grab bar at a minimum height of 19 inches (485 mm).
It is worth noting that the ICC A117.1 Standard, referenced by the IBC, requires an 18-inch minimum vertical grab bar at water closets. While this is not mandated by the ADA Standards, they do allow for a second grab bar within the 12-inch clearance above the horizontal grab bar, provided there is a minimum separation of 1½ inches.
In terms of exceptions, single-occupant private toilet rooms accessed only through a private office are permitted to install certain access features, such as grab bars, after construction if the walls are reinforced or have blocking. However, these rooms must still meet all space requirements and remain sized for accessibility.

Plumbing and building codes
The IBC mandates the presence of accessible unisex or "family" toilet rooms in specific scenarios. For instance, in assembly and mercantile occupancies, if six or more toilet fixtures are required, the IBC dictates the need for a unisex toilet room. This room should include privacy latches and contain up to one lavatory, one water closet, and either one urinal or an additional water closet.
ADA Standards, on the other hand, focus on the accessibility features within toilet rooms rather than dictating their number. These standards encompass specifications such as clear floor space, doorway dimensions, toilet stalls, sinks, and grab bars. Grab bars, in particular, are essential for individuals with motor disabilities, providing stability and support. They are typically installed near toilets, showers, and bathtubs.
Both plumbing and building codes work together to ensure that toilet rooms are accessible and adequately designed. For example, when it comes to alterations for qualified historic buildings, plumbing and building codes may permit exceptions. In such cases, the codes may require at least one toilet room for each gender that complies with specific accessibility standards or a single unisex toilet room that meets the necessary criteria.
Additionally, plumbing and building codes address the placement of toilet facilities in relation to accessible routes and entrances. They outline requirements for situations where toilet rooms are not connected by an accessible route, specifying that toilet facilities should be provided on a story connected to an accessible entrance. Furthermore, in alterations where adhering to specific accessibility standards is technically unfeasible, the codes provide alternatives. For instance, they may allow for a single unisex toilet room that complies with established accessibility standards, as long as it is located in the same area and on the same floor as the existing inaccessible toilet rooms.
