Should you repair existing bathroom or fully renovate? Depends on substrate condition, cost-of-repair vs replace ratio, and ownership horizon. Decision tree from 500+ KW bathroom assessments helps you choose.
When Repair Makes Sense
- Cosmetic issues only (tile grout cracking, vanity dated).
- Structure sound (no warping, soft spots).
- Plumbing connections solid.
- Owning home another 5–10 years.
- Existing components are mid-tier or above (worth refreshing).
When Full Renovation Makes Sense
- Substrate damage (water-rotted floor, walls).
- Multiple ongoing issues (leaks, finish failures, drawer issues).
- Bathroom is 18+ years old, stock-tier original.
- Layout doesn't work for your household.
- Selling within 2 years and aged bathroom will deduct buyer offers.
Partial Replace Options
Vanity-only replacement: $1,500–$2,800 if rest of bathroom sound. Tile-only replacement (keeping vanity, fixtures): $4,500–$9,500. Fixture upgrade (faucets, showerhead, toilet): $1,500–$3,500.
Frequently Asked Questions
How do I know if my bathroom needs full renovation or just repair?
Repair if cosmetic-only and structure sound. Full renovation if substrate damage, layout doesn't work, or 18+ year stock-tier.
What's the cost ratio for bathroom repair vs full renovation?
Repair: $1,500–$8,500. Full renovation: $24,000–$38,000. If repair would cost more than 25% of full renovation, full renovation usually makes more sense.
Can I just replace the vanity and keep the rest?
Yes if rest of bathroom is sound — vanity-only replacement runs $1,500–$2,800. Common upgrade extending bathroom life 8–15 years.
Should I replace just the tile?
Yes if vanity, fixtures, and substrate are sound. Tile-only replacement: $4,500–$9,500.
