Cost to Repipe a House
Typical range, whole-house · 2026 U.S. averages
Repiping a house costs $4,000 to $15,000 in 2026, averaging around $8,000. PEX is the most affordable option; copper costs more in both material and labor. Home size, number of bathrooms, and wall access are the biggest cost drivers.
Cost Breakdown
| Item | Typical Cost | Notes |
|---|---|---|
| PEX repipe (2 bath) | $4,000–$8,000 | Fastest, flexible tubing |
| Copper repipe (2 bath) | $8,000–$15,000 | Higher material + labor |
| Per-fixture estimate | $500–$1,000 | Rough planning figure |

| Permit & inspection | $150–$1,000 | Varies by jurisdiction |
What Affects the Cost
Pipe material
PEX is cheaper and faster to install than copper; copper costs more but is preferred by some for longevity and resale.
Home size & bathrooms
More fixtures and longer runs mean more pipe, fittings, and labor hours.
Wall & slab access
Open walls or crawlspaces are cheaper; slab foundations and finished walls require cutting and patching.
Drywall restoration
Repiping opens walls — factor $1,000–$3,000 for patch, texture, and paint if not included in the bid.
Cost by Region
Labor rates and material costs vary across the country. Here's roughly how the $8,000 national average shifts by region.
| Region | Typical Cost | vs National |

DIY or Hire a Pro?
A whole-house repipe is not a DIY project for most homeowners — it involves permits, inspections, and reconnecting the entire supply system. Even skilled DIYers usually limit themselves to single-line replacements.
