You may need to have the plumbing replaced if it’s old and has hazardous piping materials such as lead or polybutylene. For example, galvanized pipe needs replacing because it fills with rust, sediment, and mineral deposits, tainting your water. Your overall prices depend on the type of materials used, the home's age, and the square footage of your plumbing project. Table of Contents

Commercial vs. ResidentialThe rough-in costs for commercial plumbing a new construction typically ranges from $4 to $6 per square foot. However, the fixture cost can be considerably higher because of the heavy-duty nature of commercial fixtures. They need to be able to stand up to heavy public usage. The difference between commercial and residential plumbing is scale and complexity.
Rough-In Plumbing Cost for New ConstructionRough-in plumbing costs range from $8,000 to $12,000 for a new construction home around 2,000 square feet with 2 or 3 bathrooms. Installing new fixtures, like bathtubs, sinks, dishwashers, or toilets will cost between $450 and $1,800 per fixture or about $4,000 for all. The total cost for rough-in plumbing and installing fixtures is about $12,000 to $20,000.

Return to Top Cost to Replumb a HouseReplumbing a 1,500 square foot home costs between $2,280 and $4,080, or $0.40 to $2.00 per linear foot depending on the type of pipe used. An accurate estimate depends on the number of bathrooms, how far they are from the kitchen, where the laundry room is, and the number of fixtures. The cost to replumb a house varies widely, depending on many factors, the biggest two being the size of the house and the materials used. Most homes older than fifty years need to be replumbed because of corroded or cracked pipes. A bigger house or building will cost more to redo than a smaller one, and a home replumbed with copper pipe will cost more than one replumbed with PEX.
Cost to Repipe a House with PEXThe cost to repipe a house with PEX tubing is $0.40 to $0.50 per linear foot depending on the size of the house and the extent of replumbing you’re doing. Repiping a 2,000 square foot home with PEX costs between $2,000 and $4,000. PEX is plastic tubing or hose with many beneficial characteristics. However, PEX has only been used for about a decade, and any health risks of using plastic water supply lines are unknown.
Average Cost to Replace Galvanized PipesThe cost to replace galvanized pipes is from $2,000 to $15,000 depending on if you use PEX, copper, or another material. Replacing galvanized pipes in older homes is important because of the way galvanized pipes tend to degrade over the years. Galvanized pipe is made by coating steel pipe with zinc. As time moves on, the zinc erodes, exposing the steel.
Lead and Polybutylene Pipe Replacement CostYour lead and polybutylene pipe replacement cost is from $2,000 to $15,000, where PEX would be the cheapest, and copper the most expensive choice. The pipes must be replaced because they crack and leak from years of water treatment chemicals. Old piping is not only a hazard to your home because of water damage, but it’s a health hazard as well.
Repipe a House with Copper PipeThe cost to repipe a house with copper pipe is between $8,000 and $16,000 or about $3 to $8 per linear foot. Replacing galvanized drain, waste, and vent pipe with copper costs $13 to $15 per linear foot. Copper pipe is more expensive than PEX, but it has some excellent benefits.
Cost to Remove Existing Plumbing PipesIt can cost in the neighborhood of $1,000 to $5,000 to remove existing plumbing in an older home. Usually, it’s included in the price of repiping a home rather than treated as an individual cost. It’s a “remove as you go” type of repair to replace the plumbing in an entire house, so it’s not something you can do yourself to save money. The cost is dependent on the size of the home and the number of bathrooms and plumbing fixtures—laundry room, wet bar, mud room, etc. The cost to repair the drywall that was cut into to gain access to the plumbing will add $500 or more to your final costs. Cost to Replace Plumbing in an Old HouseIf your home is over 50 years old, it’s a good bet it’s time to replace the plumbing, at a minimum cost of $2,000 and a maximum of $15,000. The wide disparity in price is due to the size of the house, the kind of pipe you’re installing, and additional repairs you find you need to make any time you go behind walls. How long do plumbing pipes last before they need to be replaced?
Replacing the Water Main from Meter to HomeReplacing the water main will cost from $32 to $53 per linear foot or about $800 to $2,000 on average. New construction costs to install a water main and hook it up from the meter to your home will run $1,700 to $3,000 or about double the replacement costs. If you have an older home, it’s possible that the water main may hook into your home somewhere underneath it. Be prepared to have your yard torn up with a deep trench for at least a few days. The cost will vary depending on local prices and the obstacles between the street and the hookup in your home. Cost to Replace Pipes Under a HouseThe cost to replace pipes under the house is merely the cost to install a new plumbing system which can range from $2,000 to $15,000 or more. You can install new copper pipes for $3 to $8 per linear foot, or $0.40 to $0.50 per linear foot for PEX hose. Pipes do run under houses, many times in concrete. It is quite common to leave the old pipes in place after disconnecting them. The new pipe is simply installed in the path of least resistance. Depending on the style of your home, the pipe can be installed in the attic or under a crawl space. Cost to Repipe a Mobile HomeReplumbing a mobile home costs between $2,000 and $4,000 depending on the size and model. The plumbing setup in a mobile home is different than that in a stick-built home. In a mobile home, all the plumbing is in the floor rather than the walls, so it has different costs and will be less expensive. Return to Top New Plumbing Pipe & Materials PricesIf you want to put new pipes in your home or you’re building a home, there are three types of new plumbing pipe available that are building-code approved for homes—copper, PEX, and CPVC (chlorinated polyvinyl chloride). PEX and CPVC are both plastics and are excellent alternatives to the pricey copper piping. Plumbing Material Rates
PEX Plumbing & Tubing CostsPEX piping costs $0.30 to $0.82 per linear foot. PEX piping is very affordable for plumbing jobs, and being flexible is easy to install. It’s noncorrosive and is a popular pipe for radiant heating setups. Copper Pipe PricesCopper pipe prices range from $1 to $3 per linear foot and are the best kind of pipe to have in your home. Copper resists bacteria and extremely durable, but it is becoming an increasingly difficult material to source and thus valuable, hence the likelihood of it falling prey to thieves.
CPVC Pipe Material CostChlorinated Polyvinylchloride Piping (CPVC) piping materials cost from $0.40 to $1.56 per linear foot. A popular replacement material for metal pipes, CPVC pipe is rigid plastic piping that has thick walls and can be used for hot and cold drinking water pipes. CPVC is easy to install and meets the most rigorous building codes. Polybutylene, Galvanized, Lead, and Cast-Iron PipingAs time has moved on, we’ve found that the pipes we’d been using in homes across the country are not the best kind and have been discontinued. If you find these types of pipes in your home, they should be replaced as soon as possible.
Return to Top Whole-House Plumbing Cost FactorsThe cost of new plumbing or replumbing a house is affected by many different factors simply because every home is different in size, layout, and water features within the house.

Should I replace old copper with PEX?While copper is an excellent material, no material is perfect. You can develop some problems with your copper pipes, and PEX is often a great replacement that can eliminate these problems. Keep hot water hot: PEX keeps the water warmer as it flows through the pipe so that you get hotter water on the other end.
How much does it cost to repipe a 1600 sq ft house?The average cost to replumb a house will vary between $5,000 to $7,000. However, the total cost of repiping a house may be as high as $15,000 depending on a variety of factors. These variables include pipe location, number of bathrooms, quantity of fixtures, and how many stories a home includes.
How long does it take to repipe a house with PEX?A complete repipe can take anywhere from a few days up to a week. Smaller homes can be repiped in as little as two days, while large homes with multiple bathrooms can take much longer. However, it's important to note that you won't necessarily be unable to use your plumbing during that entire time.
How much does it cost to replumb a house with PEX?A whole-house plumbing replacement using PEX in an average two-bathroom home costs between $4000-$7000. The exact cost for a plumbing replacement or “repipe” would hinge on the total number of fixtures in your home, the size of your home, the accessibility of your pipes, and whether it is a single or two story home.
