Chapter 6: Plumbing Elements and Facilities Bathing Rooms Transfer Shower Compartment [§608] Transfer shower compartments must have a seat (folding or non-folding) and are sized so that controls and grab bars are usable from the seat. The depth is also limited so that support is available from the back wall once transfer is made to the seat. This is why the width and depth are absolute, not minimum, dimensions of 36”. These dimensions are measured from the centerline of opposing walls since prefabricated units often have rounded corners and slightly tapered walls to get the form off the mold. The entry must be at least 36” wide on the face of the compartment. 12 )etulosba( ”63 36” (absolute) In dwelling units, a seat is not required if walls are properly reinforced to support later installation of a seat in compliance with the Standards (§608.4).
