This drawing outlines the spatial clearances and mounting criteria for a folding shower seat in an accessible shower stall. The seat requires a finished top height between 17 inches minimum and 19 inches maximum above the finished floor, and must withstand a bending moment from a 250 pound-force load. Seat dimensions range from 22 to 23 inches in total width with specific return clearances, and the folded projection from the mounting wall is restricted to a maximum of 6 inches. Seat extensions must be provided for shower stalls exceeding 36 inches in depth.
22" MIN - 23" MAX 14" MIN - 15" MAX 1 1/2" MAX FULL DEPTH OF STALL 15" MIN - 16" MAX 2 1/2" MAX NOTE: SHOWER SEAT MATERIALS SHALL BE STRONG ENOUGH TO WITHSTAND A MAX BENDING MOMENT FROM A 250 LBF LOAD SEAT SHALL NOT EXTEND MORE THAN 6" FROM THE MOUNTING WALL WHEN FOLDED PROVIDE SEAT EXTENSION FOR SHOWER STALLS OVER 36" DEEP TOP OF SEAT TO BE 17" MIN TO 19" MAX ABOVE FIN FLOOR
