Figure 28. Clear Floor Space at Water Closets.
[Note: Figure 28 applies to water closets not installed in toilet stalls. Figure 30 covers toilet stalls.]
For a side or forward approach, the water closet must be located along the back wall and the centerline of the water closet must be 18 inches (455 mm) from the side wall with the side grab bar.
For a forward approach/transfer, when a lavatory is installed beside the water closet, there must be a clear floor space at the water closet that is a minimum 48 inches (1220 mm) in width (parallel to the back wall) and a minimum of 66 inches (1675 mm) in length. An accessible lavatory may overlap the clear floor space at the back wall as long as a minimum 18 inches (455 mm) clearance is maintained between the centerline of the water closet and the nearest edge of the lavatory. Grab bars are provided on the side and back wall (see figure 29).
For a side approach/transfer, when a lavatory is installed beside the water closet, there must be a clear floor space at the water closet that is a minimum of 48 inches (1220 mm) in width (parallel to the back wall) and a minimum of 56 inches (1420 mm) in length. An accessible lavatory may overlap the clear floor space at the back wall as along as a minimum 18 inches (455 mm) clearance is maintained between the centerline of the water closet and the nearest edge of the lavatory. Grab bars are provided on the side and back wall (see figure 29).
For a forward and side approach or for a lateral transfer, there must be a clear floor space at the water closet that is a minimum of 60 inches (1525 mm) in width (parallel to the back wall) and a minimum of 56 inches (1420 mm) in length. There must be a clear floor space of 42 inches (1066 mm) minimum from the centerline of the water closet to the nearest obstruction/wall. A lavatory may not overlap this clear space. Grab bars are provided on the side and back wall (see figure 29).
