About bathroom remodelers in Williamsburg
Bathroom remodelers renovate bathrooms with new showers, tubs, tile, vanities and fixtures. Bathroom remodelers demolish and rebuild baths: waterproofing showers, setting tile, installing tubs and walk-in showers, vanities, toilets, lighting and exhaust fans, and making accessibility upgrades like grab bars and curbless showers.
Typical cost: $12,000–$35,000 for a mid-range full bathroom. See the full cost guide

Questions to ask this contractor
- Ask about waterproofing: Look for named membrane systems, not just cement board.
- Review tile work photos: Check grout lines, niches and transitions in past jobs.
- Confirm licensed plumbing: Fixture relocation should be done by a licensed plumber.
