So, you’re building a new house. Congratulations! Undertaking new construction is always an exciting venture. That is, until you start to get stressed about the money you’re spending…

If you’ve come to this article hoping to see a wonderfully low number for the cost of plumbing for a new house, unfortunately, we don’t have the news you’re looking for. Adding new plumbing systems in a brand-new house is a large and expensive undertaking.

But don’t dismay! We’ll break down the average costs you can expect based on the size and scope of your project, as well as other factors.

Average Rough-In Plumbing Costs

There are two phases of plumbing for a new construction build. First, a plumber must complete the rough-in plumbing. Later, they can install the plumbing fixtures you actually use on a day-to-day basis.

Rough-in plumbing is necessary for any new house construction project, as it lays the foundation for the connections and water supply systems needed to make your home livable. During rough-in, a professional plumber will come in and run pipes from your main water line to each area of your house, including bathrooms, kitchens, laundry rooms, outdoor areas with hoses, and more. Most importantly, rough-in sets up the connections and water supply systems vital for plumbing fixtures.

The average cost of rough-in plumbing for a new house ranges from $8,000 to $15,000, depending on your home’s size and the project’s complexity. This often breaks down to roughly $4.50-$5 per square foot.

Costs for Fixtures and Appliances

After a plumber has completed the rough-in plumbing for a new house, they can then move on to installing the fixtures. Plumbing fixtures are what allow you to interact with your home, enabling you to use water straight from your taps, showers, sinks, and other appliances. They include items such as:

  • Toilets
  • Faucets
  • Shower heads
  • Sinks
  • Dishwashers
  • Water heaters

The cost of fixtures varies significantly depending on the type of fixture you choose to install. For example, low-flow toilets tend to be a bit pricier than regular toilets. The same goes for luxury faucets and shower heads. If you want to use more high-end fixtures throughout your home, this can add up quickly.

On average, you should expect to pay between $500 and $2,000 for significant plumbing fixtures like dishwashers, water heaters, and washing machines. Shower heads and faucets have lower upfront costs in the $50-$200 range. Depending on how many bathrooms you have in your new house, the total cost for new fixtures can be anywhere between $2,000 and $10,000.

Plumbing Cost Factors

There are a handful of factors that can impact the final cost of your plumbing project. The most important ones to be aware of are:

  • 🔭 Size and scope: The larger the plumbing project, the pricier it will be. That’s why rough-in plumbing for a large house costs significantly more than for a smaller home. Even if you’re building a smaller home, costs can add up if you want multiple bathrooms or unique features. Additionally, if your home has multiple stories, it will require a more complex plumbing setup.
  • 📍 Location: If you live in an area where labor costs are higher, that can also increase your total cost. In Minnesota, it will cost more to plumb a new house in the Twin Cities than it would in a small town in Southern Minnesota.
  • 🚿 Fixtures: As we mentioned above, high-end fixtures can increase your final bill significantly. If you’re looking to cut costs wherever possible, consider opting for simple, basic fixtures. But if you want premium appliances, prepare to spend premium money.
  • 🏗️ Excavation: If the plumbing project requires excavation or trenching, expect to pay extra. This work can be complicated and time-consuming, so it will increase your overall costs. (Most new construction projects require some excavation to run drain pipes out of the home and connect water lines to your home.)
  • 🔧 Pipe materials: The type of pipes you choose can also influence the cost. Copper piping is typically more expensive than PVC piping, for example.
  • 👷‍♀️ Labor costs: The cost of labor can also vary depending on the size and scope of your project, as well as where you live. Expect to pay more if you hire a team of master plumbers with decades of experience. Even though it may be tempting to go the DIY route to save some money, you definitely want to leave this significant project in the hands of qualified professionals.
