It costs $500–$15k to repipe a home in the US. Size, materials, region, and scope drive the spread; expect the midpoint to land near $7.8k for a typical job.

The national average to repipe a home is about $7.8k. Half of homeowners pay between $500 and $15k depending on scope, materials, and region.

Small jobs run roughly $500; mid-size jobs land near $7.8k; large or premium scope can exceed $15k. Size, finish level, and labor rate are the three biggest cost levers.

For a small home, expect to pay near the low end - roughly $500–$650. Less square footage, fewer fixtures, and simpler access all cut labor hours.

For a large home, costs typically run $12k–$15k or more. Larger areas mean more materials, more labor hours, and often premium finishes that bump the per-unit cost.

The cheapest plumbing system options start near $500. Save by choosing builder-grade materials, keeping the existing layout, and bundling the work in the shoulder season.
