Bathrooms are small rooms with an unusual amount of work packed into them: plumbing, waterproofing, tile, ventilation and electrical all inside a few dozen square feet. That's why cost per square foot runs higher here than almost anywhere else in the house, and why a tub-to-shower conversion can cost more than refinishing an entire bedroom. The ranges below group typical projects into three budget levels so you can see what changes as scope grows.
Typical budgets: good, better, best
Good
Roughly 35–50 sq ft, fixtures stay in place
Existing plumbing locations kept, tub stays a tub, no layout or wall changes.
- New stock vanity, toilet and fixtures
- Tub or shower surround replaced in place
- Standard ceramic tile floor
- Fresh paint, mirror, lighting and exhaust fan
Better
Roughly 50–80 sq ft, light layout changes
Tub-to-shower conversion or a shifted vanity; drain and supply adjustments within the same wet wall.
- Tiled walk-in shower with proper waterproofing
- Semi-custom vanity with a stone top
- Porcelain or large-format tile flooring
- Upgraded fixtures, lighting and ventilation
Best
Roughly 80+ sq ft, primary bath fully reworked
Full gut, relocated fixtures, possible footprint expansion into adjacent space.
- Curbless or fully tiled wet area with a freestanding tub
- Double custom vanity with premium stone
- Heated floors and designer tile work
- High-end fixtures, glass enclosure and layered lighting
Where the money goes
- Materials
- Tile, waterproofing, vanity, shower glass and fixtures. Shower glass and stone tops are the most common budget surprises.
- Labor
- Labor share is higher than most rooms — demolition, plumbing, waterproofing, tile setting and finish work all happen in a tight space, and tile is slow, skilled work.
- Permits
- Like-for-like fixture swaps often don't need a permit. Moving drains, adding circuits or altering framing generally does, with inspections at rough-in and completion.

Location
Plumbing and tile labor rates vary sharply by market, and permit fees are set locally — the same bathroom can differ meaningfully between metros.
Size and type of bath
A powder room with a sink and toilet is a fraction of a primary bath with a shower, tub, double vanity and separate water closet.
Moving fixtures
Relocating a toilet or shower drain means opening the floor and reworking waste lines — one of the biggest cost jumps available in a small room.
Tile choice and layout
Tile size, pattern and how far up the walls it runs change labor hours as much as material cost. Mosaics and herringbone take far longer to set.
Hidden water damage
Bathrooms hide leaks. Rotted subfloor or framing behind a failing shower pan is common and only shows up after demolition.
What's not included — and why your estimate differs from a contractor's bid
- Mold, asbestos or lead paint remediation
- Subfloor or framing repair discovered during demolition
- Whole-house plumbing or water heater replacement
- Window replacement or new exterior venting runs
- Structural work to expand the room's footprint
- Décor, towels and accessories
These ranges are averages across many homes. A contractor bidding your bathroom prices your conditions — the real measurements, your local labor rates and permit fees, the state of the plumbing behind the wall, their schedule, and their overhead and margin. In a room this small, one discovery during demolition can shift the total more than any finish choice. Treat a guide as a starting expectation and compare real bids line by line.
Frequently asked questions
How much does a bathroom remodel cost in 2026?
It depends mostly on whether fixtures stay put. Keeping the layout and replacing finishes sits at the low end; converting a tub to a tiled walk-in shower sits in the middle; a full primary-bath gut with relocated plumbing sits at the top. Run a free Nail-IT estimate for numbers based on your actual room.
Why are bathrooms so expensive per square foot?
Because nearly every trade works in the same few dozen square feet: plumbing, waterproofing, tile, electrical and ventilation. Small rooms don't reduce the number of steps — they just compress them.
Is a tub-to-shower conversion worth it?
It's one of the most popular upgrades and usually costs more than a like-for-like tub replacement because of waterproofing, tile work and glass. If your home has no other tub, consider resale before removing the last one.
Do I need a permit for a bathroom remodel?
Replacing fixtures in their existing locations often doesn't require one. Moving drains or supply lines, adding circuits or changing framing generally does. Rules are local — a Nail-IT estimate checks your ZIP code.
How long does a bathroom remodel take?
A straightforward refresh can take a couple of weeks. A full gut with a tiled shower typically runs longer, since waterproofing, tile and grout each need cure time before the next step.
