A shower bench is a permanent structure that must withstand both water exposure and the weight of the user. Framing is typically done using pressure-treated lumber or pre-formed waterproof components that connect directly into the wall studs and floor framing. It is critical that the bench is sloped slightly toward the shower drain to ensure that water does not pool on top of the seat. Once the bench is constructed and anchored, it must be thoroughly waterproofed using a system that includes seams, corners, and joints to prevent water from infiltrating the structural components of the bench.
