Choose what stays and what moves
Keeping the tub, shower, toilet, or vanity in place may simplify the project. If fixtures move, ask for the plumbing and electrical work to be clearly described and inspected where required.
Ask how wet areas are built
Request the waterproofing product and installation steps for showers and tub surrounds. Clarify substrate preparation, transitions, slope, drain details, and who is responsible for testing before tile.
Check ventilation and allowances
Confirm the fan’s capacity, duct termination, and any electrical changes. Separate tile, vanity, fixture, glass, and labor allowances so substitutions do not surprise you.
