Whole House Repiping Cost by Pipe Material

Why Pipe Material Is the Biggest Cost Variable

When plumbers quote a whole house repipe, the pipe material affects the project in two ways. First, the raw material cost per linear foot varies significantly between PEX, copper, and CPVC. Second, the labor time changes because each material requires a different connection method. PEX uses crimp rings or push-fit connectors that take seconds per joint, copper requires soldering every connection which takes minutes per joint, and CPVC uses solvent cement that needs curing time between connections. A home that takes two days to repipe with PEX might take four days with copper, which means double the labor bill.

PEX Repiping Cost

PEX (cross-linked polyethylene) is the most affordable and most commonly chosen material for residential repiping in 2026. The material costs $0.40 to $2.00 per linear foot depending on the pipe diameter, with 3/4-inch main lines at the higher end and 1/2-inch fixture lines at the lower end. The fully installed cost, including labor, fittings, manifold, and basic connections, runs $3.50 to $7.00 per square foot of home area.

For a typical home, that translates to these total project costs:

• 1,000 square feet (1-2 bathrooms): $3,500 to $7,000
• 1,500 square feet (2 bathrooms): $5,250 to $10,500
• 2,000 square feet (2-3 bathrooms): $7,000 to $14,000
• 2,500 square feet (3+ bathrooms): $8,750 to $17,500

PEX repiping is faster than copper because the flexible tubing can be routed through walls in long continuous runs from a central manifold to each fixture. This "home run" layout eliminates joints inside walls, which reduces both installation time and future leak risk. Most PEX repipes are completed in two to three working days for a standard-sized home. For a deeper look at PEX specifically, see the PEX piping cost, pros, and cons guide.

Copper Repiping Cost

Copper remains the premium choice for homeowners who want the longest proven track record. The material costs $2.00 to $8.00 per linear foot, with the wide range reflecting both the pipe diameter and fluctuations in copper commodity prices. The fully installed cost runs $8.00 to $14.00 per square foot of home area.

For a typical home:

• 1,000 square feet: $8,000 to $14,000
• 1,500 square feet: $12,000 to $21,000
• 2,000 square feet: $16,000 to $28,000
• 2,500 square feet: $20,000 to $35,000

The higher cost reflects both the material premium and the additional labor required. Every copper joint must be soldered by a skilled plumber, which slows installation considerably compared to PEX. Copper pipe is rigid, so it cannot flex around obstacles, meaning the plumber needs more fittings (elbows, tees, couplings) and more wall openings to route new lines through the structure. A copper repipe typically takes three to five working days. For a direct comparison, see copper vs PEX repiping cost.

CPVC Repiping Cost

CPVC (chlorinated polyvinyl chloride) is a rigid plastic pipe that costs $1.50 to $3.25 per linear foot for materials. The fully installed cost falls between PEX and copper, typically running $5.00 to $9.00 per square foot of home area. For a 1,500 square foot home, expect $7,500 to $13,500 total.

CPVC was a popular alternative to copper through the 1990s and 2000s, but it has become less common for new repipe work because of well-documented brittleness problems. CPVC becomes increasingly fragile as it ages, particularly when exposed to high temperatures in attic spaces or chemical interactions with certain pipe hangers, insulation materials, and water treatment chemicals. When CPVC fails, it typically cracks and splits rather than developing a slow leak, which can cause sudden water damage.

Most plumbers in 2026 recommend PEX over CPVC for new repipe work unless local code specifically requires rigid pipe. For more on CPVC issues, see CPVC pipe problems and replacement cost.

Side-by-Side Cost Comparison

For a 1,500 square foot home with two bathrooms, a kitchen, and a laundry hookup, here is how the total installed costs compare across materials:

• PEX: $5,250 to $10,500 (2-3 day install)
• CPVC: $7,500 to $13,500 (2-4 day install)
• Copper: $12,000 to $21,000 (3-5 day install)

The PEX option saves $4,500 to $10,500 compared to copper on a job this size. Even at the high end of PEX pricing, it costs less than the low end of copper pricing for the same home. This cost gap has made PEX the dominant choice for residential repiping, with industry estimates suggesting that over 80 percent of new residential plumbing installations use PEX.

Material Cost Per Linear Foot vs. Installed Cost Per Square Foot

You will see repiping costs quoted two different ways: per linear foot of pipe and per square foot of home area. Both are useful but they measure different things.

Per linear foot is the material cost of the pipe itself. A typical home needs 200 to 500 linear feet of pipe depending on size, layout, and fixture count. At $0.50 per foot for PEX, 300 feet of pipe costs $150 in materials. At $5.00 per foot for copper, the same 300 feet costs $1,500. But the raw pipe material is a small fraction of the total job cost.

Per square foot of home area is the fully installed cost including labor, fittings, manifold or distribution system, shutoff valves, permits, and basic fixture reconnections. This is the more useful number for budgeting because it accounts for the total project cost rather than just the pipe. When a plumber quotes $5.00 per square foot for PEX repiping of a 1,500 square foot home, the total comes to $7,500.

What Else Affects the Cost Beyond Material Choice

Pipe material determines the base cost, but several other factors can push your actual total above or below the ranges listed here. The number of fixtures matters because each one requires a dedicated supply run, shutoff valve, and connection. A home with 15 fixtures costs more to repipe than one with 8 fixtures even if the square footage is identical.

Accessibility makes a major difference. Homes with crawl spaces or unfinished basements allow the plumber to route new pipe below the floor, minimizing wall openings. Homes on slab foundations require routing through the attic and down interior walls, or in some cases jackhammering the slab, both of which add substantial labor time. Two-story homes cost more because of the complexity of vertical pipe routing, as covered in the two-story house repiping cost guide.

Post-plumbing restoration is the most commonly overlooked cost. Drywall repair and painting after a repipe adds $1,000 to $5,000, and some plumbing quotes exclude this work entirely. Read the repiping drywall repair cost guide for a detailed breakdown of what to expect.

Which Pipe Material Should You Choose

For most homeowners, PEX is the clear winner on cost, installation speed, and performance. It costs 40 to 60 percent less than copper, installs faster, has fewer potential leak points (because it uses fewer joints), and has a 40 to 50 year expected lifespan. The only situations where copper might be preferable are homes with water chemistry that is aggressive to plastic piping, areas where building codes require metallic pipe, or homeowners who specifically want the premium material for resale value.

Avoid CPVC for new installations unless your local code specifically mandates it. The brittleness issues are well documented, and PEX provides similar corrosion resistance without the cracking risk.

If your existing pipes are galvanized steel, polybutylene, or lead, the material you are replacing them with matters less than the fact that they need to be replaced. Any of the modern options will be a dramatic improvement over deteriorated galvanized, failure-prone polybutylene, or health-hazardous lead pipes.
