What is bathroom square footage?

Bathroom square footage is the total floor area of a bathroom measured in square feet. A standard full bathroom is 36-50 sq ft (3.3-4.6 m²). A half bath is 18-24 sq ft. A master bathroom is 60-160 sq ft.

1 ft² = 144 in² 1 ft 1 ft (12 in)

Getting started

How to Calculate Bathroom Square Footage

To calculate bathroom square footage, measure length and width of the bathroom floor in feet and multiply length × width. A 5 × 8 ft (1.52 × 2.44 m) bathroom equals 40 sq ft (3.7 m²). Subtract bathtub and shower base footprints from floor area for tile estimates.

1. Measure the floor

Measure length and width in feet. Record shower stalls and vanity nooks as separate sections.

2. Subtract fixed fixtures

Subtract bathtub and shower base footprint from the floor area for tile or vinyl coverage.

3. Order tile or flooring

Add 10-15% extra tile for cuts around fixtures. Diagonal patterns need 15-20% extra.

Quick reference

Reference

1 acre = 43,560 square feet
1 square yard = 9 square feet
1 square meter = 10.764 square feet
1 square inch = 0.00064516 square feet
Area: 300 ft² × Price: $2.80 / sq ft Total: $840.00 estimated material cost

Material pricing

Calculate Cost of Materials

Bathroom tile costs $7-25 per sq ft installed. Multiply bathroom area by the unit price to get total tile cost.

There are 2 steps to calculate material cost:

  1. Enter the price per box of tile and the square footage each box covers (printed on the box label).
  2. The Square Foot Calculator divides bathroom area by box coverage and multiplies by box price. Add grout, mortar, and labor separately.

A 40 sq ft bathroom needs about 44-46 sq ft of tile (10-15% waste factor). Order 1-2 extra boxes from the same dye lot for future repairs.

Should I include the bathtub area in bathroom square footage?

Yes, the area under the bathtub is included in total bathroom square footage. However, for tiling projects, subtract the bathtub footprint from the floor area since you won't tile under it.

How do I calculate tile for bathroom walls?

Measure the height and width of each wall, multiply for wall area, then subtract windows and doors. Use the Wall with Window calculator for walls with openings.

What is the minimum bathroom size?
