DIY vs. Licensed Contractor — San Antonio Bathroom Remodel
| Task | DIY Feasibility | Contractor Required? | Notes |
|---|
| Painting walls + ceiling | High | No | Straightforward DIY |
| Replacing mirror, towel bars | High | No | Simple DIY |
| Replacing vanity (no plumbing move) | Moderate | TSBPE-licensed plumber for hookup | DIY remove/install; licensed plumber for supply/drain connections |
| Replacing toilet (standard) | Moderate | TSBPE plumber for supply line | SA code requires licensed plumber |
| Tile floor replacement (no subfloor issues) | Low-moderate | No (if no permits required) | Good DIY skill needed; waterproofing critical in San Antonio humidity |
| Shower pan replacement | Low | Recommended | Waterproofing failures are the #1 SA shower remodel callback |
| Shower tile installation | Low | Recommended | Requires proper substrate prep for SA humidity |
| Tub-to-shower conversion | Very low | Yes — requires slab work, licensed plumber | Do not DIY slab cuts in San Antonio |
| Electrical (new circuits, GFCI) | Very low | Yes — TECL required | Code violation if unlicensed |
| Plumbing rough-in changes | No | Yes — TSBPE license + permit | Required by Texas law |
DIY-Friendly Scope in San Antonio
A realistic DIY-friendly partial remodel in San Antonio:
- Demo existing vanity and toilet (disconnect plumbing after licensed plumber shutoff)
- Prep and prime walls; tile backer install on shower (above existing pan)
- Paint walls and ceiling
- Re-hang new vanity cabinet (without plumbing connections)
- Reinstall fixtures once licensed plumber completes rough connections
Budget reality: The savings from partial DIY on a mid-range San Antonio bathroom remodel (~$15,000 full scope) is typically $1,500–$3,000 on labor — offset by 2–3 additional weekends of work and the risk of rework if tile or substrate prep is inadequate.
