Chapter 6: Plumbing Elements and Facilities Bathing Rooms Roll-In Shower Compartments [§608] Roll-in shower compartments provide access for shower chairs and other wheeled mobility aids without the need to transfer to a seat. The Standards provide specifications for a standard type and an alternate type of roll-in compartment. A seat can be provided in roll-in showers (and is required in those roll-in showers that must be provided to serve a portion of accessible transient lodging guest rooms). If a seat is provided, it must be folding so that it does not impede use with a shower chair or other wheeled mobility aid. Standard Roll-In Shower Compartment Recommendation: Providing a folding seat in roll-in shower compartments offers greater usability by allowing transfer options. The ICC ANSI A117.1 Standard, which is referenced by the International Building Code, requires a folding seat in each roll-in shower compartment. 4
