Plumbing Needs for the ADA Bathroom Requirements

Grainger Editorial Staff

Part of running a business is ensuring that your facility accommodates everyone who walks through the door. In 1992, the Americans with Disabilities with Act (ADA) became effective. This legislation was designed to open up services and employment opportunities to the millions of Americans with disabilities. The document outlines several guidelines to help businesses ensure they’re abiding by the regulations. Learn all about the ADA requirements and how to ensure each feature in your bathroom is up to code:

Toilet Talk

ADA toilet requirements state that each appliance must have a minimum width of 60 inches and enough space around to accommodate a wheelchair. The seat’s height must be between 17 and 19 inches above the floor. The level for flush control has to be placed on the open side of the toilet with the clearest floor space while being mounted no higher than 44 inches above the ground. In addition, grab bars must be installed behind the toilet and on the nearest wall or partition, depending on which is closer in proximity.

Toilet paper dispensers must be seven inches minimum and nine inches maximum in front of the water closet measured to the centerline of the dispenser. Dispensers should not be a kind that controls delivery or does not allow continuous paper flow.

Hand Care and Accessories

The ADA bathroom sink height requirement states each appliance must be installed with the front of the higher of the rim or counter surface 34 inches maximum above the floor. If hand soap and dispensers and towel dispensers are provided, they must be located within the unobstructed reach range (48 inches maximum and 15 inches minimum). Hand dryers must either be motion-activated or touch-free devices. In addition, each hand dryer must not protrude from the wall more than four inches.

ADA bathroom mirrors located above countertops should be installed with the bottom edge of the reflecting surface 40 inches maximum above the ground and stand-alone mirrors must be installed with the bottom edge of the reflecting surface 35 inches maximum above the floor.

Drinking Fountains

When it comes to drinking fountains, not only does the height of the appliance have requirements but so does the water flow itself. The spout must provide a stream of water four inches high, minimum and needs to be located five inches, maximum, from the front of the unit. This is so that a cup can be inserted under the spout for an individual, who, because of a disability, would otherwise be incapable of using the appliance. Spout outlets of drinking fountains must be 38 inches minimum and 43 inches maximum above the ground.

Basic ADA Bathroom Dimensions

A single wheelchair must be able to rotate freely within a bathroom facility. Sixty inches in diameter is required to complete a 180-degree turn. Make sure you have enough space to abide by the ADA bathroom size code.

Not properly complying with the current guidelines could result in a lawsuit. Be sure to verify that your bathroom facilities are up to code before any construction or installation.
