The Americans with Disabilities Act provides guidelines that regulate the construction and compliance of handicapped bathrooms, according to the 2010 ADA Standards for Accessible Design. Common regulations involve grab bar hand rails, toilets, hand dryers and clear floor space.
Grab bar hand rails in restrooms must have a smooth surface and be anchored securely, explains the ADA Standards for Accessible Design. Hand rails should be between 34 and 38 inches off the ground with a minimum of 1 1/2 inches between the rail and where it is anchored. ADA requirements necessitate that the diameter of the handrail be between 1 1/4 inches and 1 1/2 inches. To prevent injury, bars must have rounded edges.
Toilets that adhere to ADA standards must have ample room to the side or in front of them to accommodate a wheelchair, states the ADA Standards for Accessible Design. Toilets must be at least 60 inches wide and 17 to 19 inches above the ground. Horizontal grab bars need to be located behind the toilet and on the nearest wall. Flush levers should be located no more than 44 inches above the floor.
To comply with ADA regulations, hand dryers must be either touch free or motion activated, says the ADA Standards for Accessible Design. Dryers cannot extend from the wall more than 4 inches.
