Proper prep work can save thousands and weeks of headaches. Here's what every homeowner should do before the first tile is pulled.
Starting a bathroom renovation without preparation is one of the most common mistakes homeowners make. A little planning up front can mean the difference between a smooth six-day project and a six-week ordeal.
1. Set a realistic budget — and add 15%
Contractors universally recommend building a contingency into your renovation budget. Hidden issues like outdated plumbing, asbestos in older homes, or water damage behind walls are not uncommon.
2. Sort your permits first
Bathroom renovations that involve moving plumbing or adding electrical circuits typically require a permit. Your contractor should handle this, but confirm before work starts.
3. Choose your fixtures before demo day
Lead times on fixtures — especially specialty items like walk-in tubs or custom vanities — can be 4–8 weeks. Order them before your contractor swings the first hammer.
4. Make arrangements for the disruption
If it's your only bathroom, you'll need a plan. Many homeowners rent a portable toilet or arrange to shower at a gym or family member's home during the project.
5. Document everything in writing
Get a detailed scope of work, materials list, and payment schedule in writing. A signed contract protects both you and your contractor.
