Bathrooms are small but dense: plumbing, waterproofing, tile, ventilation, and electrical all land in a few dozen square feet. Cost per square foot runs higher than almost any other room, and the difference between a good and a bad job is mostly invisible waterproofing work.

Estimated range — based on BLS OEWS national average wages and BLS PPI material indexes applied to Our Haus baseline unit costs, as of June 2026. Estimates are shown as a range and help set expectations. They are not a quote, a verified price, or an appraisal of what a contractor will charge.
Every trade has to work in the same tiny room in sequence, and the fixed costs — permits, waterproofing, a shower valve, a vanity, a toilet — do not shrink with the room. A 40-square-foot bathroom and a 70-square-foot bathroom often differ by only a few thousand dollars in total.
Plan on the full on-site duration, typically three to six weeks. Cure times for mortar, waterproofing, and grout are not compressible, and shower glass usually arrives a week or two after tile is finished.
