What goes into the cost of a bathroom remodel
Where the money goes in a bathroom project, and the decisions that change the total most.
Updated October 2026
Scope sets the price
A refresh that keeps the layout and swaps fixtures is a very different job from a full gut that moves plumbing. Decide which one you want before asking for quotes, so every contractor prices the same project.
The main cost factors
- Layout changes. Moving a toilet, shower or sink means moving drains and supply lines, which adds plumbing labor and often permit work.
- Shower or tub. A prefabricated shower base or tub-to-shower conversion usually costs less than a custom tiled shower.
- Tile and surfaces. The amount of tile, the material and the pattern all affect material and labor time.
- Fixtures and vanity. Stock vanities and fixtures cost less than custom cabinetry and designer fittings.
- Hidden repairs. Water damage under floors or behind walls often appears only after demolition.
- Ventilation and electrical. Adding an exhaust fan, outlets or lighting may require an electrician and permits.
Ask how each contractor handles surprises found during demolition, and whether the quote includes a set amount for them.
Accessibility upgrades
Walk-in showers, grab bars and comfort-height toilets are common additions. If accessibility is a goal, mention it up front so it is designed in rather than added later.
How to compare quotes
Compare line items, not just totals. Check who supplies the fixtures, who pulls the permits, the expected timeline, and what the warranty covers.
