Commercial washrooms needs a visible finish before tile work hides the wall. Here, fixture banks, cleaning chemicals, public traffic, maintenance access shape the decision. The waterproof backer board choice for commercial washrooms should follow those project facts.

Why fixture banks changes the wall decision

Fixture banks affects layout, fastening, and the order of inspection. Ask who will stage that point, then keep the waterproof backer board review for commercial washrooms tied to the actual room condition.

Inspection notes for cleaning chemicals

Cleaning chemicals deserves a separate check because it is easy to hide behind trim, tile, or hardware. The installer should write the specification for repeated cleaning, not a private bathroom; that makes the waterproof backer board scope measurable before finish work starts.
