How This Calculator Works
This whole-house repiping cost calculator estimates your total project cost from four inputs: project size, quality tier, the options you select, and your location. It combines material and labor rates for your chosen tier, adds typical permit costs, then applies a regional cost multiplier so the estimate reflects pricing in your state.
Estimates use 2026 cost data cross-referenced from multiple industry sources. Treat the result as a planning range, not a quote. Your final price depends on your specific scope, material choices, and local contractor availability, so collect at least three itemized bids before you set a budget.
What Affects Your Whole-House Repiping Cost
Home Size and Number of Bathrooms
$2,000 - $15,000The biggest driver of repiping cost is total pipe footage and the number of fixtures. A 1,000 sq ft one-bath home might have 300-400 linear feet of supply pipe. A 3,000 sq ft home with 4 baths can have 1,000+ linear feet. Each bathroom adds roughly $800-$1,500 to the cost. The number of fixtures - toilets, sinks, tubs, showers, hose bibs - matters as much as square footage.
Pipe Material Selected
$500 - $4,000CPVC (rigid plastic) is the least expensive at $0.50-$1.00 per linear foot in materials. PEX (cross-linked polyethylene) costs $0.50-$1.50 per linear foot but installs faster due to flexibility. PEX-A (Uponor/Wirsbo brand) costs slightly more but expands for fittings - requiring no solvent or crimp connections - which many plumbers prefer. Copper costs $3-$8 per linear foot and remains the premium choice for longevity and resale value.
Access and Drywall Patching
$1,000 - $8,000Accessible pipe runs in unfinished basements, crawl spaces, and open attics are least expensive. Pipes in finished walls require cutting drywall, routing new pipe, and patching - adding $500-$2,000 in drywall costs alone. Two-story homes with pipes running between floors in finished spaces cost significantly more. The method - full repipe vs. trenchless - affects access costs.
Original Pipe Material Being Replaced
$500 - $3,000Galvanized steel pipe (common in pre-1970 homes) is the most common reason for repiping and is labor-intensive to remove. Polybutylene pipe (gray plastic, installed 1978-1995) has a higher failure rate and repiping demand for it is common. Old copper that has developed pinholes from acidic water is also a common repipe trigger. Lead pipe removal in pre-1930 homes may require additional testing and disposal protocols.
Two-Story vs. Single-Story
$1,500 - $5,000Running new pipe from a first-floor supply to second-floor bathrooms requires fishing pipe through finished wall cavities or accessing through attic or crawl space above. This work is more labor-intensive and invasive than a single-story repipe. Two-story homes typically cost 30-50% more per square foot to repipe than single-story homes of equal size.
