Inputs explained

Bathroom size
Area of the bathroom footprint in square feet.
Fixtures budget
Toilet, tub/shower trim, valves, accessories allowance.
Tile/shower budget
Tile, shower walls, pans, and surrounds allowance.
Vanity/counter budget
Vanity cabinet, top, sink, faucet.
Labor/ft²
Demolition, install, finish work per square foot.
Plumbing allowance
Allowance for rough/finish plumbing; increase if moving fixtures.
Contingency
Buffer for surprises (water damage, rot, code fixes).

How it works

Labor = size × labor/ft². Base cost = fixtures + tile/shower + vanity + plumbing allowance + labor.

Contingency is a percent of base to cover surprises. Total = base + contingency.

Formula

Labor = Size × Labor $/ft²
Base = Fixtures + Tile + Vanity + Plumbing + Labor
Contingency = Base × Contingency%
Total = Base + Contingency
Cost/ft² = Total ÷ Size

When to use it

  • Budgeting a bathroom remodel before gathering bids.
  • Comparing light refresh vs midrange vs upscale by tweaking allowances.
  • Checking cost per sq ft for ROI in flips or rentals.

Tips & cautions

  • Increase plumbing allowance if moving drains or converting tub to shower.
  • Use higher contingency for older homes or suspected water damage.
  • Adjust labor for tile complexity and finish level (niches, patterns, glass).
  • Does not include permits, design fees, or structural changes—add separately.
  • Assumes a single-phase remodel; multiple mobilizations can raise labor.
  • No line-item for lighting/paint—include in labor or adjust allowances.

10–20% is common. Increase for older homes or if moving plumbing/doing waterproofing fixes.
Shower glass or custom niches?
Increase tile/fixture or labor allowances accordingly.
Lighting/paint/fans?
Fold into labor or raise allowances; this focuses on major bathroom components.
DIY vs pro labor?
