Line drawing shows roll in shower with no seat.
Shower is at least 60 inches long and 30 inches deep. It is enclosed on three sides and open along one long side. A grab bar is mounted on all three walls (may be three bars - one on each wall). Shower controls and shower head are mounted no more than 27 inches from one of the side walls. A clear floor space is provided outside the shower that extends the entire length of the shower (minimum 36 inches wide by 60 inches long). A dashed line is shown indicating a possible location for a lavatory along the wall furthest away from the controls and shower head and in the required clear floor space for the shower.
