Estimating the cost of house repiping involves several critical factors, including the type of pipe material, the diameter of the pipes, the size of the house, the number of plumbing fixtures, and their location, to name a few. Other costs, such as obtaining building permits, disposal of old pipes, and other add-on services, can significantly impact the total cost. Our in-depth overview of home repiping prices aims to assist you in estimating the total expected cost. It is designed to account for all potential variables and provide you with a rough estimate of your repiping project's financial implications.
The Average Plumbing Costs by House Size
The house's size and structure determine the expense involved in repiping a house. Multi-story homes or homes with complex layouts, like those with multiple bathrooms and hot tubs, require more materials and labor to mount new plumbing systems, resulting in a cost rise. The age of the house also plays a role, as older homes may require extensive work to bring the plumbing up to code.
Let's delve into the average expense needed to plumb a house, depending on its size.
How Much Does It Cost to Repipe a 1,000-sq.-ft. House?
A 1000-square-foot house is typically a smaller, single-story building with one or two bedrooms and bathrooms. Depending on the set layout, its plumbing system may include kitchen sinks, bathroom fixtures, water heaters, and possibly a laundry area. Because the square footage and plumbing needs are relatively modest, plumbing costs are affordable, ranging from $1,300 to $2,650 per project. This range is influenced by the complexity of the installation, the type of pipes used, and the contractor's rate. Plus, the plumbing cost for a 1,000-sq.-ft. house could rise if unexpected complications arise during the plumbing project. That is why it's essential to prepare for unforeseen circumstances.
How Much Does It Cost to Repipe a 1,200-Square-Foot House?
A 1,200-sq.-ft. house is a compact, likely single-story residence, generally comprising two or three bedrooms, a couple of bathrooms, a kitchen, and a laundry area. The home's layout, the number of plumbing fixtures, and the current state of the existing plumbing network can greatly influence the final cost to plumb a 1,200-sq.-ft. house. On average, you should expect to spend from $2,000 to $3,750, depending on the type of piping materials used. Additional considerations like local labor rates, complexity of installation, and any repairs or upgrades needed due to older, outdated plumbing can also impact final costs.
How Much Does It Cost to Plumb a 1,500-sq.-ft. House?
A 1,500-square-foot house is usually a moderately sized, single or split-level building, typically comprising three or four bedrooms, two to three bathrooms, a kitchen, and a laundry area. It has extensive plumbing systems, including water supply lines, waste lines, and fixtures. Given the size and complexity of the system, the average cost to plumb a 1,500-square-foot house usually falls between $2,700 and $4,980. However, this range can fluctuate based on the layout specifics, the number and type of fixtures and appliances, the choice of piping materials, and labor rates in the area.
How Much Does It Cost to Plumb a 2,000-sq.-ft. House?
A 2,000-square-foot house is generally a larger, possibly multi-story home with three to four bedrooms, three bathrooms, a kitchen, a laundry area, and potentially additional features like a dishwasher, water filters, or a water softener system. As such, the home's plumbing system will be more extensive and complex, featuring an interconnected network of water supply lines, drainage pipes, and various plumbing fixtures. Considering the amount of material and time required for such a project, the average cost to plumb a 2,000-sq.-ft. house usually falls between $3,760 and $7,200 and could be even higher in some cases.

The Cost to Repipe a House by the Number of Plumbing Fixtures
The total plumbing cost in your home is directly proportional to the number of fixtures and appliances that need plumbing services. This includes but is not limited to sinks, toilets, showers, bathtubs, water heaters, and washing machines. Consequently, an increase in fixtures, particularly in areas such as bathrooms and kitchens, will raise the overall plumbing expenditure. Simply put, when budgeting your plumbing project, remember that the more fixtures you have, the higher the cost will be.
Here are the average plumbing costs by the type of fixtures to be installed.
Type of Fixture
The Average Cost Range
Washing machine
$450 - $1,700
Dishwasher
$400 - $600
Water heater
$600 - $1,800
Sink and faucets
$400 - $600
The Average Cost to Plumb a House by Pipes Location
The location of your pipes dramatically affects the average cost of plumbing a house. Accessibility plays a crucial role in this aspect, with pipes located in easily accessible spots like behind drywall usually costing less than those located in tighter, harder-to-reach areas such as crawl spaces or beneath concrete. Projects involving the latter tend to be more labor-intensive and, therefore, can considerably hike up the total cost of the plumbing project.
The Cost to Replace Plumbing in the House by Pipe Diameter
The total project cost may also fluctuate by pipe diameter as larger pipes, like those draining waste, require more material and labor to be mounted. However, the pipe diameter is chosen based on the plumbing needs of your house. So, while smaller diameter pipes might be cheaper, they may not be suitable if the house requires more water flow. Make sure to consult an expert plumbing contractor to determine the right size of pipes for your home.

The Cost to Plumb a New House by Pipe Material
The cost of a plumbing project also varies based on the type of pipe material used. There's a variety of plumbing pipe materials available in the market, including copper, PEX, PVC, and galvanized steel, varying in price and characteristics.
Copper, although durable and highly resistant to corrosion, is the most expensive choice due to its overall quality and price fluctuation in the market. On the other hand, PEX (cross-linked polyethylene) tubing is a flexible plastic tubing material that is cheaper and easier to install than copper, making it a popular choice for residential plumbing. Due to its low cost and chemical resistance, PVC (polyvinyl chloride) is used for drain, waste, and vent pipes. Galvanized steel, though once popular, is less common now due to its high possibility of rusting. On top of that, the cost to replace galvanized pipes is usually higher compared to PEX and PVC.
Here are the average plumbing prices by material type.

Additional Services Adding to the House Repiping Cost
In addition to the fundamental expenses involved with rerouting a home's plumbing system, a range of other aspects should be considered when preparing for such a project.
Firstly, there are inspection fees to consider. Depending on the property's age and the work's extensiveness, hiring a professional to assess the current state of the plumbing could be necessary. This could identify any immediate or long-term issues that may affect the repiping process or the overall performance of the new plumbing system.
Secondly, it's essential to include the permit fee in the plumbing installation cost calculator as you require it to embark on extensive projects. Local authorities vet the entire process from planning to completion, checking if pipes, vents, valves, and other elements of a plumbing system have been installed correctly and safely.
Third, the specific environmental condition of where the house is located, precisely the type of soil surrounding the property, could impact the average price to plumb a house. Certain soil types can have a corrosive effect on piping materials, resulting in premature pipe failure if appropriate measures are not taken. On the other hand, some soils can be too firm or heavy, requiring more effort and machinery to excavate for the repiping process, boosting the labor cost.
Lastly, you should consider the cost of removing and disposing of the existing pipe system. This process involves navigating the complexities of following appropriate disposal measures per local regulations. It may require a specialized team and additional equipment to safely remove the old pipes from the property without causing any damage to the structure. Moreover, different kinds of materials may need different disposal methods. Hence, the costs associated with this crucial step contribute significantly to the overall budget of the repiping project.
