Installing PEX plumbing typically costs $4,000-$10,000 for a whole-house repipe, with an average near $6,500 for a standard-size home. The final price depends on house size, pipe access, fixture count, local labor rates, and whether walls or flooring need repair.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-house PEX repipe | $4,000 | $6,500 | $10,000 | Typical 1,500-2,000 sq ft home |
| Small home repipe | $2,500 | $4,000 | $6,000 | Compact layout with accessible pipes |
| Partial PEX replacement | $350 | $900 | $2,000 | Limited pipe run or localized repair |
| New-construction plumbing | $2 per sq ft | $4 per sq ft | $7 per sq ft | Rough-in and fixture connections vary by scope |
Typical PEX repipe prices by home size
A full PEX repipe commonly runs $4,000-$10,000 for a one- or two-bathroom home of about 1,500-2,000 square feet. Smaller homes with open basements may fall below that range; larger homes, multiple bathrooms, or difficult wall access can exceed it. The estimate generally covers pipe, fittings, labor, and connecting existing fixtures, but not extensive drywall or tile restoration.
For a straightforward whole-home replacement, budgeting about $3-$7 per square foot is a useful first estimate. Some contractors price by fixture or pipe run instead, so the quote should identify what is included. Assumptions: U.S. mid-range labor rates, standard PEX tubing, normal access, and no major structural repairs.
What pipe, labor, and access add to the quote
Labor is often the largest part of a repipe because workers must route supply lines, connect fixtures, pressure-test the system, and open or patch access points. Materials vary with pipe length, fitting count, manifold design, and whether the job uses PEX-A or PEX-B. The table shows common whole-home quote components; contractor estimates may combine several items.
| Quote component | Typical range | Pricing basis | What changes the charge |
|---|---|---|---|
| PEX pipe and fittings | $500-$1,800 | $0.50-$2 per ft for tubing, plus fittings | Pipe grade, diameter, and layout |
| Plumbing labor | $2,000-$5,500 | $75-$150 per hour | Crew size, access, and fixture count |
| Manifold and shutoff valves | $300-$1,200 | Per system | Number of branches and valve quality |
| Wall access and patching | $300-$2,000 | Per project | Drywall, tile, cabinets, and finish level |
| Old pipe removal and disposal | $150-$700 | Per project | Pipe material and disposal requirements |
Ask whether the quote includes shutoff valves, pressure testing, disposal, and surface repairs.
How square footage and pipe access shift the price
House size matters, but pipe routing and fixture count can matter just as much. A 1,200-square-foot home with three bathrooms may need more branches than a larger home with two bathrooms. Two-story layouts can require longer runs and additional access openings, while unfinished basements or crawl spaces often reduce demolition work.
PEX tubing is commonly installed in 1/2-inch lines to individual fixtures and 3/4-inch trunk lines or branches, depending on the design. A home with more than 2,500 square feet or four or more bathrooms may require additional labor and materials, often pushing the estimate above $10,000. Replacing galvanized steel or copper also takes longer when fittings are corroded or hard to reach.
One extra bathroom or a closed, finished ceiling can add hundreds to several thousand dollars. Confirm that the plumber has counted every fixture and specified where new lines will run.
How long a PEX installation takes and what labor covers
A typical whole-house repipe takes about 1-3 days with a two- or three-person crew. A small partial replacement may take 2-6 hours, while a large home with multiple floors, difficult access, or extensive testing may take several days. Water may be shut off for part of the work, so the schedule should state when service is expected to resume.
Labor charges often reflect more than the time spent pulling tubing. The crew may need to protect floors, remove old pipe, drill through framing, install supports and shutoffs, connect fixtures, and test for leaks. Request an estimate that separates plumbing work from drywall, paint, or tile restoration. Some plumbing companies coordinate patching; others leave it to a separate contractor.
Regional labor rates change the same repipe quote
Labor and permit costs can vary substantially by location. A similar project may cost 10%-25% more in high-cost coastal cities than in many Midwest or Southern markets. Rural areas may have lower hourly rates but higher travel or minimum service charges, especially where plumbing contractors are limited.
Local code may require permits or inspections, and fees commonly range from $50-$500 depending on jurisdiction and project scope. Older homes can also need code-related upgrades, such as accessible shutoffs or approved fire-stopping at wall penetrations. Check local permit requirements before comparing contractor totals. A low bid that excludes required inspections may not represent the final price.
Three sample PEX installation quotes for common jobs
| Job example | Scope and labor | Estimated total |
|---|---|---|
| Small ranch, 1,100 sq ft | One bathroom, accessible crawl space, about 18-24 labor hours | $3,000-$5,000 |
| Two-story home, 1,800 sq ft | Two bathrooms, finished walls, about 32-48 labor hours | $5,500-$9,000 |
| Larger home, 2,600 sq ft | Four bathrooms, longer runs, added access work, about 50-70 labor hours | $9,000-$15,000 |
These examples assume standard PEX and existing fixture locations. Costs rise if the project relocates fixtures, replaces a water heater, or includes substantial finish repair. Compare quotes using the same fixture count, pipe route, and restoration scope.
PEX versus copper for a whole-house replacement
PEX usually costs less to install than copper because it is flexible, uses fewer fittings, and can reduce labor time. A whole-house copper repipe may run roughly $8,000-$16,000 or more, compared with $4,000-$10,000 for many PEX projects. Copper may be preferred in some situations, but material and labor prices vary by market and design.
A localized PEX repair can cost $350-$2,000 when the rest of the supply system is sound. Replacing the whole system may be more practical when leaks are recurring or old pipes are deteriorating in several areas. Compare the cost of the repair with the age and condition of the remaining pipe. A plumber should explain whether a patch addresses one isolated failure or leaves a broader risk.
Where homeowners can trim a PEX plumbing estimate
Keep existing fixture locations when possible; moving a sink, shower, or laundry connection adds pipe, labor, and finish work. Clearing access to crawl spaces, basements, and utility areas can also reduce setup time. For a repipe, ask whether an accessible manifold layout can simplify future shutoffs without adding unnecessary controls.
Get at least three written quotes with matching scope, tubing type, warranty, permit responsibility, and patching terms. Avoid choosing solely by the lowest total if the quote omits testing or disposal. Controlling access work and avoiding unneeded fixture relocation are often the most reliable savings. Scheduling outside peak emergency demand may help, but any discount depends on local contractor availability.
