Rough-In Plumbing Cost Breakdown
The average cost to rough-in plumbing for a bathroom is $7,000. However, it can range from as low as $750 to as much as $20,000. The final price depends on the piping material, home size, labor fees, number of fixtures, and more.
Each piping material has its pros and cons at different price points. It’s common for homeowners to choose a different type of piping material when remodeling their homes. The piping material factors into the total cost.
Copper piping is durable and resistant to corrosion and bacteria. It can last for 50 years on average, but it can last up to 80 years with proper maintenance. The cost of using copper pipes for rough-in plumbing in your bathroom is $3 to $8 per linear foot.
PEX piping is flexible and resistant to corrosion. It requires fewer connectors than copper and isn’t as vulnerable to freezing temperatures. You can expect to pay $.40 to $2 per linear foot for PEX piping.
CPVC piping is corrosion-resistant and can withstand high heat and water pressure. On average, homeowners pay $0.50 to $1 per linear foot for rough-in plumbing in their bathroom.
Your local licensed and insured plumber is your go-to pro for rough-in plumbing for your bathroom. Hiring a plumber costs $45 to $200 per hour, but the average range is $80 to $130 per hour. Depending on the plumber and the region in which you live, you can potentially pay an additional $50 to $300 in travel fees.
The size of your home will determine the distance between each bathroom and the piping material required for your plumbing lines. On average, you’ll pay more for a three-bathroom rough-in job in a 2,000-square-foot home with bathrooms on different sides of the building than for a job in a 1,250-square-foot home with bathrooms that share a wall.
Number of Bathrooms
The number of bathrooms you need rough-in plumbing for can impact your final price. Here are some cost estimates for rough-in plumbing by the number of bathrooms involved in the project:
|Number of Bathrooms||Cost|
|1 Bathroom||$1,500 – $3,000|
|2 Bathrooms||$3,000 – $6,000|
|3 Bathrooms||$4,500 – $9,000|
|4 Bathrooms||$6,000 – $12,000|
The type of fixture you need rough-in plumbing for will influence this project’s actual cost. Let’s look at some of the average prices you can expect for each type:
|Faucet||$230 – $480|
|Double Faucet||$400 – $600|
|Toilet||$350 – $3,500|
|Sink||$300 – $5,500|
|Bidet||$1,500 – $2,900|
|Bathtub||$500 – $2,750|
|Shower||$1,500 – $3,500|
Number of Fixtures
As you might expect, the number of fixtures can drive up the cost of material and labor. For example, rough-in plumbing for dual sinks and a walk-in shower in a primary bathroom will cost more than a half bath or a powder room.
If you need a permit to get the bones of your dream bathroom installed, it can cost $30 to $500.
What Will It Cost Me to Do My Own Rough-In Plumbing?
There’s no denying that you can save money on labor fees by doing the rough-in plumbing for your bathrooms on your own. While most homeowners love to save a few bucks wherever they can, this project requires skills, time, and extra know-how.
Even if you’re handy with tools, some homeowners insurance only covers work completed by a pro, not DIY jobs. This means any water damage that occurs due to faulty pipe connections will have to come out of your pocket, which can potentially be thousands more than the initial labor fees. So, keeping this all in mind, a rough-in plumbing job is best left to a licensed and insured plumber near you.
