How to Use the Whole-house PEX Repiping Material Cost Calculator

The Whole-house PEX Repiping Material Cost Calculator is a simple online tool designed to help homeowners and contractors estimate the cost of repiping a house using PEX (cross-linked polyethylene) piping. This calculator provides an approximate cost of materials based on the size of your home, the number of plumbing fixtures, and the current market price of PEX tubing.

What Is PEX Repiping?

PEX is a modern, flexible plastic pipe widely used in residential plumbing due to its ease of installation and resistance to scale and chlorine. Repiping your home with PEX can solve issues like pipe corrosion, water leaks, and low water pressure.

How to Use the Calculator

Step 1: Enter Your Home's Square Footage
In the first field, type the total square footage of your home. This helps estimate the base amount of pipe required for routing throughout the house.

Step 2: Enter the Number of Plumbing Fixtures
Fixtures include sinks, toilets, showers, bathtubs, water heaters, dishwashers, and washing machines. Each fixture adds extra pipe length due to direct connections and dedicated lines.

Step 3: Input the PEX Cost per Foot
Look up the current price of PEX tubing per foot, or use a default (e.g., $0.50/ft) for a quick estimate. This field allows the calculator to adapt to market changes or bulk discount rates.

Step 4: Click “Estimate Cost”
The calculator will display:

• The estimated total feet of PEX needed
• The total material cost in USD based on your input

Example

If you enter:

• 2,000 sq. ft.
• 10 fixtures
• $0.50 per foot

The tool will calculate:

• 3,000 ft of PEX required
• $1,500 in material cost
