What are the Most Common Bathroom Remodel Mistakes?
Avoiding these common mistakes can save you from costly repairs and headaches down the road.
1. Poor Ventilation
This is the number one cause of mold and mildew in bathrooms. Your exhaust fan must vent outside, not into the attic.
"Inadequate ventilation leads to peeling paint, warped cabinets, and health hazards." 3
What to do: Install a high-quality exhaust fan that is properly sized for your bathroom and vents to the exterior. Run it for at least 20 minutes after every shower.
2. Skipping Waterproofing
Tile and grout are not waterproof. Water will penetrate and cause damage behind the walls. You must use a liquid membrane or sheet waterproofing system in showers and wet areas.
What to do: Invest in a quality waterproofing system and follow the manufacturer's instructions to the letter. This is not a place to cut corners.
3. Wrong Fixture Sizes
Measure twice, buy once. Check door clearance, vanity-to-toilet spacing, and shower dimensions before you purchase anything.
What to do: Create a detailed floor plan with accurate measurements before you shop for fixtures. This will save you from costly returns and installation headaches.
4. Cheap Materials in Wet Areas
MDF cabinets swell and crack when exposed to moisture. Laminate flooring warps in bathrooms. Use marine-grade plywood or solid wood for cabinets. Choose water-resistant flooring like luxury vinyl plank or tile.
What to do: Invest in quality materials that are designed for wet environments. They may cost more upfront, but they will last decades longer.
5. Skipping Permits
Plumbing and electrical work require permits in most jurisdictions. Unpermitted work can lead to insurance denials, resale issues, and safety hazards.
What to do: Check with your local municipality to determine which permits are required for your project. It's a small price to pay for peace of mind.
