ADA Bathroom Layout: Public Restrooms Requirements & Plans

Persons with disabilities face a lot of problems when it comes to architectural design elements. Whether it be building premises, stairs, or bathrooms, disabled people mostly have difficulty in using these places. Let’s see ADA bathroom layout.

That’s why the Americans with Disabilities Act (ADA) has established minimum requirements and guidelines for public restrooms and commercial bathrooms with proper ADA bathroom layouts. These guidelines apply to all government, state, local, parks, institutes, and commercial businesses for new and renovated construction sites.

Today in this blog, we will tell you about all the regulations and guidelines that come under the ADA regarding bathrooms.

Whether you’re constructing public restrooms or private bathrooms, you have to follow a set of rules and standards. The latest ADA law was passed in 2010 which is applicable to a variety of public places such as restaurants, shopping malls, city councils, schools, universities, stations, and business facilities, or any commercial place that has restrooms.

To fulfill all the required ADA criteria, you need to follow all types of rules regarding all the accessories inside the ADA bathroom as well as the entrance. You may have already seen these types of public bathrooms in hotels, motels, and dormitories.

The first thing that you should always keep in mind is to build an ADA bathroom in a place that is easily accessible to people with disabilities, including people in wheelchairs. 

After this, there should be enough space inside so that they can use the toilets easily. Also, this space should be smartly designed so that wheelchairs can be moved freely inside the bathrooms. 

You have to carefully design the ADA bathroom layout, including toilet seats, showers, and sinks. There should be sufficient space near these things to grab the handles and bars so it can facilitate maneuvering or transfer movements.

Center of the Bathroom

According to ADA, you can mount the toilet and the sink on both the rear or opposite wall. However, there should be a minimum area of 60 inches (1.5 m) in diameter for maneuvering the wheelchair. 

If the door opens inside, it should have 12 inches (30 cm) for the swing area. Also, the opposite wall should be empty so that there will be enough free space in the center and no obstacles while rotating the wheelchair.

In addition to that, the space between the sidewall and the toilet needs to be 18 inches (46 cm). To move the wheelchair freely, the toilet should fit 60 inches (1.5 m) in diameter.  

Sink Area

Another vital part of the bathroom is the sink. So make sure that there is enough room around that, about 30 by 48 inches (76 cm x 1.2 m). It should be at least 48 inches (1.2 m) of distance from the center of the sink to the clear space, without any obstacles.

Place a sink that is 30 inches (76 cm) wide so that the user can freely use that with an ample amount of space around. Also, leave a free space of 18 inches (46 cm) between the center of the sink and the sidewall.

  • If you want to install a built-in sink, the cabinet also needs to be 34 inches (86 cm) from the ground.

  • Not only people with disabilities in wheelchairs use the mirrors, but also people with other limitations use them as well. So, it is necessary to put another mirror at least 74 inches (1.9 m) away from the floor so that people who can stand straight can use the mirror comfortably.

ADA Bathroom Bars Requirements

Handles and Grab Bars

The grab bars and handles are a significant part of ADA bathrooms, and the regulations regarding them are strict. You have to install multiple bars near the toilet, sink, and bathing areas. These handles and bars should be made from suitable materials that can bear heavy loads and sudden agitations.

Toilet Bars

The toilet bars should be  33 to 36 inches (84 – 91 cm) from the floor or according to the ADA toilet height. Put at least two grab bars so that person in a wheelchair can easily use them.

Use the wall grab bars of at least 36 inches (91 cm) long and sidewall grab bars of 54 inches (1.4 m) long. They will help people with disabilities while transferring and positioning.  

Bath Area Bars

Like the toilet and sink grab bars, shower area bars are also vital. They are generally placed on the back or control wall and mounted 33 to 36 inches (84 – 91 cm) from the bottom of the bath. If you want to install them on the sidewall, place them at least 42 inches (1 m) long.

The basic guidelines regarding the grab bars height are 33 to 36 inches (84 – 91 cm). However, this is highly dependent on the size of the bathtub and shower area. 

Make sure to use grab bars with a diameter around 1.25 to 1.5 inches (3.2 – 3.8 cm), and also, don’t forget to leave a sufficient space of about 1.5 inches (3.8 cm) between the grab bar and the wall. 

Other Requirements Of ADA Restrooms

Other Requirements Of ADA Restrooms

Apart from the clear area, toilet, and shower area requirements, there are many other things that you should keep in mind while building an ADA bathroom. Here are some of them:


Bathroom floors usually get slippery due to moisture and water. However, there is no specific regulation regarding floors; still, try to select less slippery tiles or types of floors to avoid any possible hazards.


Curbs are used to stop the water from spreading into the rest of the bathroom. So if your shower area is 36 by 36 inches (91 x 91 cm), the curb needs to be less than 0.5 inches (1.3 cm) high, and if the size of the shower area is 30 by 60 inches (76 cm x 1.5 m), there is no need to build a curb at all. 

Toilet Paper Dispensers

The position of the toilet paper dispensers should be 15 to 48 inches (38 cm – 1.2 m) from the floor. You can mount them on the sidewall under the rail. Ensure that they’re well placed at 7 to 9 inches (18 – 23 cm) from the top of the toilet.                        

Soap Dispensers

Counter soaps and Wall soaps should be on a height of 44 inches (1.1 m) and at least 15 inches (38 cm) from the floor, respectively. 

Also, mount them in such a way that they don’t protrude more than 4 inches (10 cm) from the wall. In short, soap dispensers should be in reach so that people can use them with one hand, and that too without using any type of complex wrist moves.                                                                                         

Paper Towel Dispensers

Similar to soap dispensers, paper towel dispensers should also be user-friendly and one-hand operable. Mount them at least 48 inches (1.2 m) from the floor. So that they should never become any type of obstacle during transfer and maneuvering in the bathroom. 

The Bottom Line

So these are all the ADA bathroom layout, guidelines, and regulations. Now as you know about all the laws and rules,  create a safe and user-friendly bathroom space. 

When you plan carefully and put all your efforts and time into the design. You will be able to create a space for disabled people which is not only easily accessible but also modern looking. 

Apart from the ADA bathroom 2010 federal regulation, it is advised to check the local guidelines too. With that,  you won’t miss any additional rules prescribed by the local government.
