What Affects the Cost of a Bathroom Remodel
What drives the price of a bathroom remodel, including moving plumbing, what's behind the old walls, waterproofing, tile, glass and allowances.
Size matters less than you would think
A small hall bath and a bigger one need the same fixtures and plumbing, just more tile.
Size matters once it adds fixtures: a second sink, or a separate tub and shower, each bring plumbing and finish work.
No dollar figures here; every bathroom differs.
Moving the plumbing
What moves is usually the biggest factor.
- Nothing moves: new fixtures hook up to pipes already there.
- A toilet or shower drain moves: it must slope to the main line, so a new spot needs a new path underneath, often requiring a permit.
- Basement or crawlspace below: drain work is often done from underneath.
- Concrete slab: cutting and patching concrete adds time and money.
Chino does some of the plumbing and electrical himself and brings in licensed trades where the work requires them.
What is behind the wall
Nobody can see inside a wall before it's opened. Older bathrooms hide soft subfloor under a leaking toilet, rotted framing, or old galvanized pipe and wiring. Newer houses have surprises too, like green board where cement board belongs.
Ask how anything found after demo gets handled and priced. That answer deserves as much attention as the total.
Waterproofing
Tile and grout let water through. The layer behind them keeps your walls dry. MC Renovation LLC works with HydroBlok and Schluter Kerdi.
The two differ in cost and labor, and one may suit a curbless or oversized shower. See the waterproofing guide. If an estimate just says "waterproof shower," ask which.
Tile, glass and fixtures
These choices move the total more than expected.
- Tile. Straight layouts go up fastest, big panels need flatter walls, and mosaics or herringbone mean more cuts. Ceiling-height tile, a niche, or tile outside the shower adds more.
- Glass. A curtain costs least, a framed door next, and frameless, made to measure, is one of the bigger items in a walk-in shower.
- Fixtures. A rain head plus a handheld takes more plumbing than one. Finishes add up.
- Vanity and top. A stock vanity and a custom stone top are far apart. See vanity and countertops.
Allowances, and comparing estimates
An allowance is a placeholder for something you haven't picked. Choose it: over, the difference is added; under, it comes off.
Low allowances make an estimate look smaller than the job you want, so check each before signing.
If two estimates come back far apart, they're usually describing different jobs: waterproofing, allowances, plumbing moves, and how each handles surprises behind the wall.
