The Essentials of ADA Compliant Toilet Rooms

This guide will walk you through the requirements for ADA-compliant toilet rooms according to the ADA Standards. It’s important to note that plumbing and building codes determine the number and type of toilet rooms and fixtures required for a facility. However, the ADA Standards specify which toilet rooms must be accessible when provided.

Required Compliance

The ADA Standards do not dictate the number of toilet rooms or fixtures required for a facility. Instead, they require access to all toilet rooms in new construction, including those for employees. However, in situations where single-user toilet rooms are clustered in one location, at least half of each use must comply. Portable single-user units must also comply with accessibility standards.

Clustered Single User Toilet Rooms

Clustered single-user toilet rooms are those that are next to or close to each other. In a cluster, no more than 50% of each use must comply. Toilet rooms and portable units must be labeled with the International Symbol of Accessibility unless all units in the cluster are accessible.

Unisex (Single-Use or Family) Toilet Rooms

In facilities where multi-user toilet rooms are provided, accessible unisex toilet rooms cannot replace access to multi-user rooms, except in cases where it is technically infeasible to make multi-user rooms compliant. Both multi-user and unisex restrooms must comply with accessibility standards. Unisex toilet rooms, when provided, must have privacy latches and contain one lavatory, one water closet, and one urinal (or a second water closet).

Medical Care and Long-Term Care Facilities

Toilet rooms in licensed medical care and long-term care facilities must comply unless serving critical or intensive care patients. However, these standards do not cover design for use assisted by medical personnel. Departures from the standards must be based on “equivalent facilitation,” meaning alternative solutions must provide substantially equivalent or greater accessibility, usability, convenience, and reliability for people with disabilities.

Additions and Alterations

In new construction, additions must comply with the ADA Standards for toilet rooms. When existing toilet rooms are altered, compliance applies to the scope of work. If some, but not all, elements in a toilet room are altered, only those elements altered must comply. If a room or space is completely altered, the entire room or space must comply.

Components of Accessible Single User Toilet Room

Requirements for accessible toilet rooms include doors, turning space, plumbing fixtures, mirrors, dispensers, shelves, and other elements. These provisions ensure compliance with accessibility standards.

Water Closets

Water closets must meet specific criteria, such as location, clearance, seat height, and flush controls. The ADA Standards allow water closets to be arranged for either a left-hand or right-hand approach.

Grab Bars

Grab bars are required on the walls beside and behind the water closet, and they can be separate or continuous. Certain clearances must be maintained around grab bars to ensure accessibility.

Toilet Paper Dispensers

Toilet paper dispensers must be mounted at an appropriate height and location.

Other Elements

Dispensers, receptacles, coat hooks, and shelves must also comply with accessibility standards when provided in toilet rooms.

Baby Changing Tables

If baby changing tables are provided, they must comply with accessibility standards as work surfaces and protruding objects.

Private Toilet Rooms Accessed through a Private Office

Private toilet rooms accessed only through a private office must meet all space requirements and be fully accessible.

Water Closets in Residential Dwelling Units

At least one bathroom in a residential dwelling unit must comply with accessibility standards. Accessible water closets in dwelling units can have exceptions that allow certain features to be provided after construction as needed.

Water Closets and Toilet Compartments for Children’s Use

Specifications based on children’s dimensions can be followed when water closets and toilet compartments are primarily designed for children ages 12 and younger. These specifications are optional and serve as alternatives to adult-based dimensions.

Portable Toilet Units

Portable single-user toilet units must provide access to at least 5% of units within each cluster. These units must comply with all requirements for toilet rooms, including clearances, turning space, and door maneuvering clearances.

Multi-User Toilet Rooms

Toilet compartments and urinals must comply with accessibility standards in addition to requirements for toilets, lavatories, mirrors, dispensers, shelves, and other elements.

Wheelchair Accessible Toilet Compartments

At least one toilet compartment in a facility with six or more compartments must be wheelchair accessible. Ambulatory accessible compartments must also be provided in these facilities.


At least one urinal must comply with accessibility standards when two or more urinals are provided in a toilet room. Accessible urinals must meet specifications for rim height, depth, flush controls, and clear floor space.
