Cost to Repipe a House: $4,000–$7,500

A PEX repipe of a house with 2 full baths and 11 fixtures costs an estimated $4,000–$7,500, and copper runs $8,100–$12,000. The estimate turns prices plumbers publish into a cost per fixture, multiplies it by the fixture count and adds a city plumbing permit. A fixture is anything a supply line feeds: a toilet, sink, tub, shower, dishwasher, washing machine or hose bib.1,2,3,4,5,6,7,8,9,10

Where the money goes

Almost all of a repipe is the installed pipe: the plumber's labor, the pipe and the fittings, which plumbers price together. The rest is the permit, which comes from the city or county and ran $37–$275 for this house across the 16 fee schedules this site has read.

PEX or copper

Either way, the plumber replaces the supply lines that carry water to each fixture. In the prices plumbers publish, copper costs about 1.8 times as much per fixture as PEX, $730–$1,070 against $360–$660. See the PEX repipe cost and copper repipe cost pages for each material by bath count and by state.

Old pipe: polybutylene and galvanized

Polybutylene is a plastic that was made between 1978 and mid-1995 for supply piping in homes. Galvanized pipe is iron pipe with a zinc coating, and it was common in homes built before the 1960s. Replacing either one across the house is a whole house repipe, priced the same way as above. See the cost of replacing polybutylene pipes and the cost to replace galvanized pipes.

Common questions

How much does it cost to replumb a house?

It is the same job as a repipe: replacing the supply lines. For a house with 2 full baths and 11 fixtures, the national estimate is $4,000–$7,500 in PEX and $8,100–$12,000 in copper, including a plumbing permit. A bigger house costs more because the estimate is priced per fixture.

What does a whole house repipe estimate include?

Two lines: the installed repipe, priced per fixture and covering labor, pipe and fittings, and the plumbing permit. It leaves out drywall patching, drain lines and anything outside the house, so a quote that includes those will run higher. The methodology lists every exclusion.

How do I check a plumber's quote?

Open the repipe cost calculator, pick your state, pipe material and bath count, then enter the quote total. It tells you whether the quote is below, within or above the estimate for the same house, and how far it sits from the midpoint.

How much is a plumbing permit for a repipe?

For a house with 2 full baths and 11 fixtures, the fee came to $37–$275 across the 16 city and county fee schedules this site has read. Some cities charge a flat fee and others charge per fixture. Each state page names the jurisdiction behind its permit figure.
