Seal & Caulk: Inspect and refresh caulk at tubs, showers, and splash zones; re-grout or seal grout as needed.
Stop Leaks Early: Check under sinks, at valves, and around the toilet for moisture or staining.
Ventilation Matters: Run a properly sized fan 20–30 minutes after showers to control humidity.
Fixtures & Traps: Tighten loose fittings; replace worn flappers, supply lines, and p-traps before they fail.
Surfaces: Replace compromised wood trims with tile base; touch up or repaint moisture-rated finishes.
