Abstract: A shower bench includes an L-shaped first brace with legs attached to vertical shower walls. A bench subassembly includes a cross brace, a foam block, and a T-shaped beam made of cementitious bonding agent that adheres the cross brace to the foam block and also adds strength to a front edge of the foam block. The brace and the block are cut to fit horizontally against the first brace with legs overlapping, such that the braces form a rigid geometric arrangement that supports the block. Ends of the braces are screwed together. The large uniform surfaces of the block are covered with tile and grout. The resulting assembly is extremely rigid and non-flexing, such that cracking of the tile and grout is substantially minimized, even when the bench is loaded up to 400 lbs.
