Wheelchair accessible vs. Ambulatory ToiletsPosted on - Wednesday, March 1st, 2023
One of my clients inspired me to write this newsletter. She asked me how many toilets needed to be accessible by the 2010 ADA/2012 TAS. This newsletter will cover multi-user restrooms, single user restrooms and restrooms that could be used for both adults and children.
In a multi-user (Gang restroom) one of the toilet compartments must have an accessible toilet used for wheelchairs. The size depends on whether the toilet is wall hung or floor mounted. Also if you are designing for children and they will be the primary user, then the size will be similar to having a floor mounted toilet even if you use a wall mounted. See the figure below
The ADA and TAS has an advisory describing what is a toilet compartment:
Advisory 213.3.1 Toilet Compartments. A toilet compartment is a partitioned space that is located within a toilet room, and that normally contains no more than one water closet. A toilet compartment may also contain a lavatory. A lavatory is a sink provided for hand washing. Full-height partitions and door assemblies can comprise toilet compartments where the minimum required spaces are provided within the compartment.
This is the figure found in the 2010 ADA and the 2012 TAS that shows the size of the wheelchair toiilet compartment.
This photo shows mulitple toilet compartments. Only one compartment will have to be provided for wheelchair users. And there are more than six toilet compartments which also requires an ambulatory compartment.
What is an Ambulatory compartment?
If the restroom has six or more waterclosets/toilets and urinals then the ADA and TAS requires that an ambulatory toilet compartment be provided IN ADDITION TO the wheelchair toilet compartment. These are for people who use other mobility devices such as walkers, crutches, etc.
2010 ADA 213.3.1 Toilet Compartments. Where toilet compartments are provided, at least one toilet compartment shall comply with 604.8.1. In addition to the compartment required to comply with 604.8.1, at least one compartment shall comply with 604.8.2 where six or more toilet compartments are provided, or where the combination of urinals and water closets totals six or more fixtures.
Single User Toilet Rooms
The ADA and TAs both require that EVERY toilet room provided be accessible.
This image shows two single user restrooms in a cluster and only one would have to comply. They opted not to take the exception, but they could have.
In a single user restrooms is provided with one toilet, then that one toilet must be accessible. If the single user restroom has two toilets, again only one of the toilets is required to be accessible.
213.3.2 Water Closets. Where water closets are provided, at least one shall comply with 604.213.3.3
