Crucial Bathroom Watchouts
- Shower Waterproofing (Do Not Cut Corners): Insist on a bonded waterproofing membrane (Schluter-Kerdi, Hydro Ban, or RedGard). Standard greenboard drywall behind shower tile fails and rots within 3–5 years.
- Exterior Fan Ducting: Make sure the exhaust fan vents completely out through the roof or soffit, never vented into the attic crawlspace.
- Plumbing Valves: Replace the pressure-balanced shower valve cartridge and shutoff valves while walls are open.
