How to Use This Calculator

Enter plumbing fixture count, a local base cost per fixture, home square footage and size allowance, material multiplier, access multiplier, wall-repair allowance, permits and contingency.

Formula & Methodology

Fixture subtotal equals fixture count × base cost per fixture. Size allowance equals square footage × entered rate. Core repipe cost applies material and access multipliers. Drywall, paint, permits and contingency are then added.

Worked example

For 12 fixtures at $650 each, 2,000 ft² at $0.50/ft², a 1.0 material multiplier, 1.15 access multiplier, $2,000 repairs, $500 permits and 10% contingency, the estimate is about $13,882.

This calculator estimates domestic water-supply repiping only unless you deliberately add other work. Drain, waste and vent replacement, service lines, slab reroutes, water heaters, hazardous materials and code upgrades may be separate.

Budgeting estimate only. Plumbing systems must comply with local code and permit requirements. Obtain an on-site scope and written quotes from appropriately licensed professionals.
