How It Works
Bathroom plumbing costs vary dramatically by scope. Cosmetic swaps (same location) are cheap; relocating drain lines in a slab foundation can be the most expensive single item in a bathroom remodel.
The Formula
Total = Labor + Materials + Permits
Labor is the biggest component (60-70% of plumbing cost)
Labor is the biggest component (60-70% of plumbing cost)
Variables
- Rough-in — Behind-wall plumbing — supply lines, drains, vents
- Finish — Connecting visible fixtures to rough-in plumbing
Worked Example
Standard remodel, 3 fixtures, no relocation: $1,800 labor + $600 materials + $250 permits = $2,650.
Practical Tips
