Some public restrooms provide shower facilities, and shower seats are necessary if the handicap bathrooms are going to include showers. Handicap bathroom supply stores provide folding shower seats. Provide L-shaped folding shower seats for shower stalls that are 36x36 inches (915mm) to comply with ADA restroom requirements. Mount a shower seat on the wall of the shower opposite the temperature control knobs at a height of 17-19 inches (430-485 mm) above the floor. Be sure that the seat allows enough space for a shower curtain at the front of the shower stall. Avoid skimpy seats; a shower seat and mounting device should be able to support 250 pounds.
