How Much Does Plumbing Cost For a New House?

On average, the cost of plumbing a new house is $7,500. The lowest estimate can come up to $1,500, but a more detailed work can even exceed $15,000.  As it is a significant investment, you must follow some plumbing tips to help you save money in the long run.

Factors That Determine The Price of Plumbing a New House

Here are some factors that help determine the exact price of plumbing a new house:

1. The Pipe’s Location

If the sewer or septic tank can’t get connected to your bathroom, you might have to end up paying more. The plumber will need to spend more time plumbing your house and even require special tools.

The plumbing price will increase if more pipes are required to be connected to the central server. Making the bathrooms accessible will help to lower the plumbing installation cost. You can place them on the house edges instead of the interior.

If needed, place the bathroom close to the sewer line or septic tank to reduce the required number of pipes.

2. Number Of Bathrooms

The plumbing price can increase if your home has more bathrooms. The number of fixtures in each room will determine the price of plumbing. A pipe will be required to be installed in every fixture.

The cost of plumbing fixtures will be more in a home with three or four bathrooms and a kitchen. You may require a plumber’s help installing plumbing fixtures for your new bath or an outdoor kitchen area.

Your project will get costlier if you have more bathrooms in your home. If you want to limit the plumbing price at your new home, restrict yourself from building more bathrooms. Having a bathroom on every floor is better than having a bathroom on every corner.

3. Materials Used For Plumbing

One of the factors that impact plumbing price includes the type of plumbing material you choose. Copper is the most expensive type of pipe material. The least expensive pipe material is PVC or a new material known as PEX.

If a lot of piping is required in your home, then plumbing costs can increase depending upon the material used. Using more copper pipes will get expensive compared to using more PVC or PEX pipes. Choose either PVC or PEX for your piping if you want the plumbing cost to be less.

4. Hourly Wage Of The Plumber

The last factor which influences the price is the hourly pay rate of the plumber. Some charge by the hour, while others charge a flat rate. If you have a lot of work at your place, selecting a plumber who charges hourly will get expensive. On the contrary, you should choose a plumber that charges on an hourly basis if you have a minor job.

When selecting a plumber, you should consider both options and compare to get the right price.

DIY Plumbing Basics Every Homeowner Should Learn

How Much Does Plumbing Cost For A New House With PEX Piping?

The price for installing a PEX pipe per square foot is 50 cents to $2. For a 2,200 square-foot home, the average cost will be $1,100 for 50 cents for a single bathroom. If you want to install a second bathroom, you can double that amount. Labor is the significant difference between PEX and copper piping.

How Much Does Plumbing Cost For A New House with Copper Piping?

The price for installing copper piping per square foot is around $2 to $5. For a 2,200 square-foot home, that would cost $4400 for a $2 price point. But, copper has a few advantages which PEX doesn’t provide. Those advantages and features might make copper piping worth it.

The installation costs are significantly high, and if there is an unexpected failure, the repairs can get really expensive. You can start by maintaining an emergency fund for unexpected breakdowns to prepare yourself. Apart from that, investing in a home warranty plan will significantly decrease the repair and replacement costs.


Plumbing a new house can become cheap if you limit the number of bathrooms in your home and use PEX piping. If you have a larger budget to spend on plumbing, you can go with the copper pipes as they have trusted performance and a longer lifespan.
