10 Renovation Mistakes That Ruin Your Bathroom (and How to Avoid Them)

Bathrooms may be small, but the cost of getting them wrong adds up fast. Here are 10 mistakes that turn a bathroom reno into a headache—and how to dodge them.

  1. Skipping the Waterproofing A beautiful shower with no waterproof membrane? Mold city. Always waterproof.
  2. Ignoring Ventilation No exhaust fan = lingering moisture, mildew, and peeling paint. Don’t skimp here.
  3. Cheap Fixtures Plastic taps and thin glass break fast. Stick to quality where it counts.
  4. Poor Layout Choices Toilets crammed against tubs. Vanities blocking doors. Measure twice. Rethink awkward layouts.
  5. Going Too Trendy Black grout and gold everything? It might not age well. Trend-light is safer long term.
  6. Forgetting Storage No shelves. No drawers. Nowhere for towels. Plan for real life, not just pretty pictures.
  7. DIY Plumbing One leak ruins the whole reno. Unless you’re licensed, leave the pipes to the pros.
  8. Bad Lighting Overhead light only = shadows on your face. Add task and ambient lighting.
  9. Poor Drainage Slope Showers that pool at the wrong end = nightmare. Your contractor should know better, but double check.
  10. Rushing the Job Tile needs time to set. Grout needs time to cure. Skipping steps ruins results.

Final Word A great bathroom feels clean, dry, and functional. Don’t let shortcuts or poor planning flush your budget. Plan carefully, spend wisely, and always think long-term.
