Chapter 6: Plumbing Elements and Facilities Bathing Rooms Shower Seats [§608.4, §610] Seats at transfer and roll-in shower compartments can be rectangular or L-shaped. The L- shaped seat affords users additional support and stability from the back wall. To facilitate transfer, the seat height (17” – 19” measured to the bathroom finish floor) approximates wheelchair seat heights. Seats must extend to a point within 3” of the compartment entry to minimize the transfer gap. Seats must withstand a vertical or horizontal force of 250 lbs. at any point on the seat, fastener, mounting device, or supporting structure. Folding seats can have legs. 2½” max 3” max 15” - 16” 18 xam ”½1 22” - 23” 2½” max 3” max 15” - 16” xam ”½1 17” - 19” ”51 - ”41
