new construction plumbing

A common goal among families is to construct and have their own home, where they will have total creative control and every space, including electrical and plumbing. Plumbing plays a critical role in any new home. Complete plumbing, including rough-in and finish plumbing, should be completed accurately and within your budget. However, the plumbing system is one of the most expensive aspects of building a new home. So, how much does new construction plumbing cost?

In this article, we’ll discuss the average cost of new construction plumbing and the benefits of hiring a professional plumber to install a plumbing system in your new home.

Average New Construction Plumbing Cost in 2024

The average new construction plumbing costs can vary significantly based on several factors, including the size of the house, the complexity of the plumbing system, local labor and material costs, and the specific features or fixtures you choose.

The typical plumbing cost for new buildings is roughly $4.50 per square foot. For a basic plumbing installation in a new house, the cost can range from $5,000 to $10,000 or more. This typically includes the installation of pipes, fittings, and fixtures for water supply, drainage, and venting systems.

Labor costs vary based on location and the complexity of the plumbing work. Plumbers often charge by the hour, and rates can range from $50 to $150 per hour or more. A significant portion of the plumbing budget goes toward labor, especially if the installation requires a considerable amount of time.

New Construction Plumbing Process

The process of new construction plumbing involves several steps to ensure a properly functioning and efficient plumbing system for a new house. Throughout the entire process, effective communication between the plumbing professionals, builders, and other contractors is essential to ensure a seamless integration of the plumbing system with the overall construction project. 

Here are six key steps in the new construction plumbing process:

  • Design and Planning — Consider factors such as the house layout, the number of bathrooms, kitchen requirements, and any additional features like irrigation systems. Create a detailed plan that includes the placement of pipes, fixtures, and appliances.
  • Rough-In Plumbing Installation — Begin the installation with the rough-in phase, where the main water supply lines, drain lines, and vent pipes are installed. Install rough-in plumbing for bathrooms, kitchens, laundry rooms, and any other relevant areas.
  • Connection to Utilities — Connect the plumbing system to external utilities, including the main water supply and sewage or septic system. Ensure compliance with local building codes and regulations during the connection process.
  • Installation of Fixtures and Appliances — Once the rough-in is complete and inspected, install plumbing fixtures and appliances, including sinks, toilets, bathtubs, showers, water heaters, and any other specified fixtures.
  • Pressure Testing and Inspections — Perform pressure testing on the plumbing system to check for leaks and ensure that all connections are secure. Schedule inspections with local building authorities to verify that the plumbing work complies with applicable codes and regulations.
  • Finalization and Completion — Make any necessary adjustments or corrections based on inspection feedback. Ensure that all fixtures and appliances are in working order and that there are no leaks or plumbing issues.

Benefits of Hiring a Professional Plumber for New Construction Plumbing

Professional plumbers bring extensive expertise and experience to new construction plumbing projects. They are well-versed in the latest industry standards, regulations, and best practices, ensuring that the plumbing system is installed correctly and complies with local codes.

  • Accurate System Design — Professional plumbers can accurately design the plumbing system based on the specific needs and layout of the new construction. Their expertise allows for the optimal placement of pipes, fixtures, and appliances, ensuring efficient water distribution and drainage.
  • Quality Workmanship — Hiring a professional ensures high-quality workmanship. Professional plumbers have the skills and knowledge to install pipes, fixtures, and appliances with precision, reducing the likelihood of leaks, clogs, and other plumbing issues in the future.
  • Compliance with Codes and Regulations — Professional plumbers stay up-to-date with building codes and regulations. Hiring a licensed plumber ensures that the new construction plumbing project meets all legal requirements, preventing potential issues and delays associated with non-compliance.
  • Efficient Problem Resolution — In the event of unexpected challenges or issues during the construction process, professional plumbers can quickly and efficiently address and resolve problems. Their experience enables them to troubleshoot effectively, minimizing downtime and disruptions.
  • Time and Cost Efficiency — Professional plumbers work efficiently, helping to complete the new construction plumbing project within the specified timeframe. Their expertise also contributes to cost efficiency by reducing the likelihood of errors, rework, and the need for additional repairs.
  • Warranty and Accountability — Reputable plumbing professionals often provide warranties for their work. This warranty offers peace of mind to homeowners, assuring them that the plumbing system is covered in case of any issues that may arise after completion.
