How to Use This Calculator
  1. Enter the total number of plumbing fixtures in the bathroom (toilet, sink, tub, shower, bidet).
  2. Set how many fixtures are being relocated to a new position — these require new rough-in work.
  3. Choose the supply pipe material: 0 = PEX (most affordable), 1 = CPVC, or 2 = Copper (most expensive).
  4. Enter your local plumber's hourly rate (national average is $85/hr).
  5. Set a contingency percentage (10–20%) to budget for surprises behind walls.
  6. Review the Total Estimated Cost, Labor Hours, and Cost per Fixture to plan your remodel budget.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Total fixtures = 3, Fixtures being relocated = 1, Pipe material (0=PEX, 1=CPVC, 2=Copper) = 0, Plumber hourly rate ($) = 85 = 5 input(s) provided
  2. Calculate Total estimated cost
    Total estimated cost = subtotal + contingency
    5474 = $5,474
  3. Calculate Fixture & material cost
    Fixture & material cost = fixtures * basePerFixture * materialMult
    1950 = $1,950
  4. Calculate Relocation surcharge
    Relocation surcharge = relocatedFixtures * relocateSurcharge
    1200 = $1,200
