Section 603.2/Accessible Bathing Facilities
ADA 2010 Section 608 covers accessible shower compartment requirements including minimum size, clearances, seat, grab bars, controls, and spray unit for roll-in and transfer showers.
ADA Section 608 provides two types of accessible shower compartments. Transfer showers (Section 608.2.1) are 36 by 36 inches clear inside dimensions with a 36-inch minimum entry width, a folding or non-folding seat on the wall opposite the entry, grab bars on the back wall and side wall, and controls on the side wall opposite the seat between 38 and 48 inches above the floor. Roll-in showers (Section 608.2.2) are 60 by 30 inches minimum with a 60-inch entry (or 60 by 36 inches with a 36-inch entry at one end). Roll-in showers may have a folding seat on the back wall. Grab bars are required on the back wall and side walls (or back wall and one side wall for the alternate roll-in configuration). The shower floor must be sloped for drainage but must not exceed 1:48 slope in the transfer area. A threshold of 1/2 inch maximum is permitted at the entry for transfer showers, and roll-in showers must have a flush threshold (no lip or curb). The shower spray unit must have a hose at least 59 inches long and a fixed and hand-held showerhead.
Why this section exists
Accessible showers allow people who use wheelchairs, walkers, or other mobility devices to bathe independently or with minimal assistance. Transfer showers are designed for users who transfer from a wheelchair to a shower seat. Roll-in showers are designed for users who remain in a shower wheelchair and roll directly into the shower compartment. The flush threshold on roll-in showers eliminates the barrier of a curb that prevents wheelchair entry. The grab bars provide support during transfer and standing. The long hose on the shower spray unit allows the user to reach all parts of the body while seated. These requirements apply to accessible guest rooms in hotels, accessible dwelling units, and public bathing facilities.
What plan reviewers look for
Plan reviewers check the shower plan and section for compartment dimensions (36x36 for transfer, 60x30 or 60x36 for roll-in). They verify the seat location, size, and mounting height (17 to 19 inches). They check grab bar locations and lengths on the shower elevation details. They verify the threshold height (1/2 inch max for transfer, flush for roll-in). They check the shower controls location (on the side wall opposite the seat for transfer, on the back wall within reach range for roll-in). They verify the shower spray unit has a 59-inch minimum hose. In accessible toilet/bathing rooms, they verify door maneuvering clearances accommodate the shower layout.
