Water Supply Re-pipe Pricing

Repiping a house typically costs between $5,200 and $19,500, with a national average around $9,750. Smaller homes with fewer fixture drops and easy access usually land near the low end. Larger homes, two-story layouts, slab foundations, and copper piping push pricing higher.

Whether you’re looking into Plumbing in San Antonio or Plumbing in Lubbock, understanding what goes into a re-pipe job helps you plan your budget before the first pipe is ever touched.

A whole-home water supply re-pipe means replacing the clean water lines that feed sinks, showers, tubs, toilets, washer boxes, water heaters, and other plumbing fixtures. It does not include drain piping or the main sewer line those are priced very differently.

What Does a Water Supply Re-Pipe Include?

A typical water supply re-pipe covers:

• • Main hot and cold water distribution lines

• • Branch lines to fixture drops

• • Shutoff valves and sink/toilet connections

• • Washer box tie-ins

• • Water heater connections

Average Cost to Repipe a House

Home Type	Typical Range	Notes
Small single-story home	$5,200–$8,450	Fewer drops and easier access keep labor down
Average 2-bath home	$7,800–$12,350	Common range for full PEX repipe
Larger 2-story home	$11,050–$19,500	More drops, longer runs, and more wall access
Copper-heavy or difficult access	$13,000–$23,400+	Material and labor both rise

What Actually Drives the Price?

 For a practical estimator, the biggest pricing factors are not just square footage. They are the number of fixture drops, whether the home is one story or two story, the foundation type, the pipe material, and how hard it is to get to the plumbing. 

• Number of fixture drops: More sinks, showers, tubs, toilets, and washer boxes mean more pipe, more connections, and more labor.

 • Hot and cold vs. cold-only: Replacing both hot and cold water lines costs more than a cold-only re-pipe because it increases material and connection count. 

• Story count: Two-story and three-story homes need longer runs and more vertical routing.

 • Foundation type: Crawl spaces and pier-and-beam homes are usually easier than slab homes. 

• Pipe material: PEX is usually the lower-cost option; copper costs more in both material and labor. 

• Access difficulty: Finished walls, tight chases, crowded utility spaces, and difficult routing all add time. 

PEX vs. Copper Re-Pipe Cost

Pipe material is one of the biggest cost drivers in a water supply re-pipe. PEX is flexible, installs faster, and usually saves labor. Copper is more rigid, more expensive per foot, and slower to install, especially in finished homes. 

Material	Typical Material Cost	Why Homeowners Choose It
PEX	$0.50–$2.00 per linear foot	Lower installed cost, flexible routing, fast installation
CPVC	$1.00–$4.00 per linear foot	Middle-ground option in some markets
Copper	$2.00–$8.00 per linear foot	Durable and familiar, but higher material and labor cost

If a homeowner is not sure which pipe material they want, a smart estimate page can show both a PEX range and a copper range. That gives the customer a realistic budget window without forcing a technical choice too early. 

Pricing by Fixture Drops

A cleaner way to estimate a water supply re-pipe is by the plumbing drops in the house. That means counting sinks, bath or shower areas, toilets, and washer hookups instead of relying only on bedrooms or square footage. 

Fixture Type	Why It Matters	Typical Pricing Impact
Sinks	Each sink adds supply branches, stops, and connections	Low to moderate add per sink
Bath/shower areas	Require both hot and cold supply plus longer runs	Moderate add per bath/shower
Toilets	Add cold-water drops and connections	Lower add per toilet
Washer boxes	Need hot and cold lines and shutoff connections	Moderate add per laundry area

For sales copy, the easiest way to explain it is this: the more plumbing drops your home has, the more material and labor your re-pipe will require. 

How Foundation and Access Impact

Foundation type matters because it changes how easy it is to route the new lines. Pier-and-beam and crawl space homes often allow easier under-floor access. Slab homes usually require more creative routing, more wall and ceiling access, or occasional overhead reroutes. If you’re dealing with a slab foundation and suspect the problem started beneath the floor, you may want to look into Slab Leak Repair in Lubbock before committing to a full re-pipe sometimes a targeted repair is all that’s needed.

Condition	Typical Effect on Cost
Pier and beam / crawl space	Usually lower labor cost
Basement	Often moderate labor cost depending on finish level
Slab foundation	Usually, higher labor costs due to access limits
Difficult access	Can add 10%–25% or more, depending on layout

Additional Costs Homeowners Should Expect

• • Permit and inspection fees: $100–$400

• • Drywall repair and paint: $400–$2,600

• • Water heater reconnects or valve updates: $200–$400

• • Old pipe disposal and cleanup: small but worth noting

How Long Does a Whole-House Water Supply Re-Pipe Take? 

Most whole-house supply repipes take about 2 to 5 days. Straightforward one-story PEX jobs can move faster. Larger homes, copper repipes, and slab homes can take longer because access and restoration work are heavier. 

Frequently Asked Questions

How much does it cost to repipe a 2-bath house?

A common range is about $7,800 to $12,350 for a full water supply re-pipe, depending on material, access, and fixture count.

Is PEX cheaper than copper for repiping?

Yes. In most homes, PEX lowers both material and labor cost compared with copper. Does repiping include drains or the sewer line?

No. A water supply re-pipe covers the clean water lines only. Sewer and drain line replacement is a separate scope and should be priced separately.

Making the Right Choice

A whole-home water supply re-pipe is a major job, but it solves recurring leaks, poor pressure, rusty water, and aging pipe problems in one shot. If smaller leaks have been the issue so far, our Leak Repair Services in San Antonio and Leak Repair Services in Lubbock can help you figure out whether a targeted fix or a full re-pipe is the smarter move for your home.

For most homes, the right pricing conversation comes down to fixture count, hot-and-cold versus cold-only scope, story count, foundation type, pipe material, and access difficulty. If you build your estimate page around those factors, the pricing feels a lot more believable to homeowners than a generic square-foot number ever will.
