Get ADA Construction Guidelines for Accessible Bathrooms
Handicap Toilet and Bathrooms Requirements
ADA (The American with Disabilities Act) guidelines regulate the construction and compliance of accessible (handicap) bathrooms. This article presents a summary of construction and design guidelines for handicap toilet and accessible bathrooms. Remember to consult with ADA for other applicable guidelines as well as other required applications.
Do You Need to Install Grab Bars or Towel Bars?
Grab bars are not intended to be used as towel bars and vice-versa. The grab bar handrail must be fully anchored with a smooth surface that can be easily grabbed. The diameter of the pipe used for this kind of purpose must be between 1-1/4 to 1-1/2 inches. ADA grab bar handrails for accessible bathrooms must be installed between 34 and 38 inches off the ground. Furthermore, keep in mind that there must be a separation between the grab bar and the surface where it is located, of at least 1-1/2 inches.
That space will provide room for proper grab and allow the hand to grab it firmly. As a matter of security, bars must contain round edges, and the handrail must be returned to the connection to posts or walls. It will prevent someone to get hurt by a sharp pointing object.
How Much Space will the Handicap Toilet Need?
A clear space with minimum dimensions of at least 30" x 48" must be provided to accommodate a single wheelchair. This space must be designed for a forward or parallel approach to the equipment. Sometimes that clear space will be located under current fixtures, but be sure to verify that there is enough room and space to allow legs to move freely under those spaces when sitting in a wheelchair.
Rotating Space per ADA Bathroom Guidelines
A single wheelchair must rotate freely inside a bathroom. For this kind of motion at least 60" in diameter is required to complete a 180-degree turn. As well as the clear space, sometimes that required space could be computed beneath fixtures.
Installation Height for Lavatories
An accessible lavatory, at least one, must extend at least 17" from the back wall and have a clearance of at least 29" from the bottom of the apron to the finished floor. The lavatory, must not be installed at heights greater than 34". If the lavatory is installed with a countertop, it should be placed no further than 2" from the front edge for maximum accessibility.
Toilet Height Requirement (ADA Compliant Bathroom)
Accessible toilet requirements must have a minimum width of 60" and sufficient space to accommodate the wheelchair to the sides of the toilet or in front of it. Also, required horizontal grab bars must be installed behind the toilet and on the nearest wall or partition, whichever is closer. Sometimes the required space cannot be achieved due to space restrictions in existing facilities, so an alternate compartment is required.
Toilet seat heights must be between 17" to 19" above the finished floor. The lever for flush control must be placed on the open side of the toilet with the clearest floor space and mounted no higher than 44" above the finished floor.
Installation Height for a Hand Dryer on Handicap Bathrooms
Hand dryers are one of the requirements easiest to comply with. ADA bathroom guidelines ask to provide hand dryers that must be either motion activated or touch-free devices. In the past, there were push-button activated dryers; these dryers must be removed, especially in public areas where you should have handicapped accessible bathrooms. Make sure you are providing touch-free equipment to comply with ADA guidelines; otherwise, you could be exposed to several fines and other legal actions.
If you are installing new hand dryer equipment, it is very important to follow ADA design guidelines and regulations. One of them is the regulation from ADA regarding the location of a hand dryer and its depth from the wall. Most hand dryers don’t have sensors alerting blind people of their location, so be sure to verify this in your handicap toilet construction process. Because of this ADA specifies that the hand dryer must not protrude from the wall more than 4 inches. If this rule is not met, there is a significant chance that a blind person can hit the hand dryer and can be injured.
Remember to verify prior to construction with the proper and current required codes and guidelines at the moment of installation for better compliance with the law.
