Small Bathroom Remodel Cost Calculator – Full Bath or Half Bath

The Small Bathroom Remodel Cost Calculator estimates the cost of remodeling a compact full bathroom or a half bath (powder room). It prices floor and wall tile by the installed square foot, adds the vanity, toilet and — for full baths — the tub or shower, then other labor and a contingency.

Formula

Tile = (L × W + wall tile area) × installed tile rate

Fixtures = vanity + toilet + tub/shower (full bath only)

Total = (tile + fixtures + other labor) × (1 + contingency)

How the Calculation Works

Step 1: Add floor area and wall tile area and multiply by the installed tile rate.

Step 2: Add fixture prices (the tub/shower only for a full bath).

Step 3: Add other labor (plumbing, electrical, paint) and the contingency.

Example Calculation

Given (example prices): 7 × 5 ft full bath, 60 ft² of wall tile at $18/ft² installed, vanity $700, toilet $300, tub/shower $1,500, other labor $2,500, 10% contingency

  • Tile = (35 + 60) × 18 = $1,710
  • Fixtures = 700 + 300 + 1,500 = $2,500
  • Subtotal = 1,710 + 2,500 + 2,500 = $6,710
  • Total = 6,710 × 1.10 = $7,381

As a half bath (no tub/shower), the total becomes (1,710 + 1,000 + 2,500) × 1.10 = $5,731.

Ways to Keep a Small Remodel on Budget

  • Keep the toilet, sink and shower in the same places to avoid moving plumbing.
  • Limit full-height tile to the wet area and paint the rest.
  • Choose standard-size fixtures that fit existing openings.
