Estimate the cost of a full bathroom remodel by size and finish.
Bathroom remodels are priced per square foot because the cost is driven by density of work, not by floor size — a 40 sq ft bathroom packs plumbing, waterproofing, tiling, ventilation and electrics into one small room. The finish tier sets that rate: a budget refresh reuses the existing layout and fittings positions, a mid-range job replaces everything in place, and a high-end job brings in stone, custom glass and specified brassware. Moving the toilet, bath or shower is treated separately because it means opening the floor and rerouting drainage, which is the most common reason a bathroom quote doubles. Labour typically runs a little over half the hard cost in a bathroom, higher than most rooms, because so much of the work is trade-specific.
Bathroom Remodel Cost
Hard cost = area x finish rate + plumbing relocation; total = hard cost x (1 + contingency%)
An estimate for budgeting only, not a quote. Regional labour rates, fixture choices and code upgrades vary widely — get itemised bids from licensed contractors before committing.
Because cost follows the number of trades and fixtures, not area. Every bathroom needs the same plumber, tiler, electrician and waterproofing regardless of size, so the fixed work is spread over very few square feet.
10-15% for a bathroom built in the last 20 years, and 20% or more for an older house, where hidden rot behind the bath and out-of-date venting are common finds once the tiles come off.
Yes. Leaving the toilet and shower where they are avoids opening the floor and rerouting the soil stack, which is why a like-for-like replacement often lands at half the cost of a re-planned bathroom.
