Properties of ADA Compliant Grab Bars
The diameter of an ADA grab bar may be either 1 ¼” diameter or 1 ½” diameter so long as specified length requirements are met. The length of an ADA grab bar is the measure from the center of one flange (end) to the center of the other flange. A standard flange is 3” to 3 ¼” in diameter. The overall total length of the grab bar, therefore, is the sum of the measurement of the bar from the center of one flange to the center of the other plus the diameter of one flange.
Height of Grab Bars in Commercial Bathrooms
Grab bars shall be installed in a horizontal position, 33 inches (840 mm) minimum and 36 inches (915 mm) maximum above the finish floor measured to the top of the gripping surface, except that at water closets for children's use complying with 604.9, grab bars shall be installed in a horizontal position 18 inches (455 mm) minimum and 27 inches (685 mm) maximum above the finish floor measured to the top of the gripping surface.
