A full remodel of a standard 5-by-8 bath, mid-grade finishes and no walls moved, runs $8,800 to $17,500 nationally (HomeGuide, 2026). Sanity-check against that, not against the per-square-foot number everyone asks for. That one lands between $100 and $500 per foot, a five-fold spread, because a bathroom's cost sits in its fixture count and its plumbing rather than its floor. The average remodeler nets 6.3% (NAHB, on 2024 numbers), which is $945 on a $15,000 bath. Demolition alone is $600 to $2,000. Leave that one line off the estimate and the profit on the whole job is gone.
What is a typical bathroom remodel cost in 2026?
$3,500 to $25,000 for an average-sized bathroom, and the tier of work decides it. HomeGuide's 2026 figures split three ways for a 35 to 50 square foot room:
| Scope | Per sq ft | 35-50 sq ft bath |
|---|---|---|
| Minor renovation - flooring, vanity, paint, fixtures | $100 - $150 | $3,500 - $7,500 |
| Partial - tub or shower, toilet, vanity, some tile | $150 - $300 | $5,300 - $15,000 |
| Full gut, layout changes, luxury materials | $250 - $500 | $8,800 - $25,000+ |
Fixr, the same year, puts the national average at $12,000 against a $6,000 to $18,000 range, and its average per-foot figure at around $120. Two cost databases, one year, and their per-foot midpoints are nowhere near each other. That is the first clue about the unit.
What should you charge per square foot for a bathroom remodel?
If a client pins you down: $100 to $150 for cosmetic work, $250 to $500 for a full gut. Then stop using it. Bathrooms are the room where floor area and cost come apart, and the arithmetic takes about thirty seconds.
Take two hall baths with identical scope - one toilet, one tub-shower, one vanity, tile to the ceiling in the wet area. A 5x7 at 35 square feet. A 6x10 at 60. HomeGuide prices the full remodel of the first at $8,800 to $17,500 and the second at $15,000 to $30,000, because the table multiplies a per-foot rate by area.
What actually changed between those two rooms? Twenty-five square feet of floor tile, some drywall, a bit more paint. Call it a day of labor and four extra boxes of tile. It is not $7,000 of difference. Every fixture, every connection, every bit of the work that costs real money is identical in both rooms.
Now run it backwards, which is where the money is actually lost. A 35 square foot powder room where the client wants the toilet on the opposite wall is a smaller room and a bigger job than a 60 square foot bath where nothing moves. Per-square-foot pricing gets that exactly wrong, in your favour on the first job and against you on the second.
What does a bathroom estimate look like line by line?
Installed cost per line, national, from HomeGuide's 2026 guide:
| Line item | Installed cost |
|---|---|
| Demolition | $600 - $2,000 |
| Bathtub replacement | $800 - $4,600 |
| Shower installation | $1,000 - $15,000 |
| Shower pan replacement | $500 - $3,500 |
| Toilet installation | $350 - $800 |
| Vanity | $400 - $4,000 |
| Countertop | $250 - $3,000 |
| Sink | $280 - $1,200 |
| Faucet | $150 - $600 |
| Tiling | $400 - $8,000 |
| Flooring | $200 - $800 |
| Exhaust fan | $150 - $550 |
| Lighting | $70 - $300 |
| Painting | $150 - $1,500 |
Labor runs 40% to 65% of the total and averages about half (Fixr). Trade rates behind that: a general contractor at $50 to $150 an hour or 10% to 20% of project cost, a plumber at $75 to $150, an electrician at $50 to $130 (HomeGuide).
Notice the width of the shower line. $1,000 to $15,000 is not a price, it is a category, and it is the line that decides whether your bid is profitable or fiction.
Where do bathroom estimates lose money?
The tile takeoff is vertical, and most estimates measure the floor. A 5x8 bath has 40 square feet of floor. The tub alcove is two 2.5-foot end walls plus a 5-foot back wall, tiled to six feet - that is 60 square feet before you touch the floor. Add a wainscot around the room and you are past 100 square feet of wall tile. Take off the floor plan and you have bought roughly a third of the tile you need, and you find out on a Thursday when the tile setter runs out.
Two inches is the line between a swap and a new branch. An offset flange repositions a toilet up to two inches in any direction, and Oatey states plainly that larger offsets risk leaks and drainage problems and are not advised. Past that you are cutting the floor, running a new branch, sorting out the vent, patching subfloor, laying tile over the patch and waiting on a rough-in inspection before any of it closes up. On a wood-framed floor that is most of a plumber's day at $75 to $150 an hour plus the trades that follow him. In a slab it is saw-cutting. Homeowners ask for it the way they would ask you to slide a nightstand across a bedroom.
What is behind the tub is unknown until the tub is out. Rot at the wet wall, a galvanized drain, a subfloor that flexes underfoot. Write an allowance line with an actual number on it and a written credit if it goes unused. A bare exclusion saying unknown conditions are billed time and materials reads to a client as a blank cheque; an $800 allowance with a credit attached reads as a plan, and it survives the comparison against the guy who did neither.
What this misses
These are national figures and homeowner-facing databases. They report what jobs sold for, not what they cost you to build. Metro labor runs to double a rural county's, and your burdened rate and overhead sit on top of every line above - which is the markup versus margin arithmetic, and it is where more profit disappears than in any takeoff error.
The published spread is genuinely wide. $100 to $500 a square foot is a factor of five. Treat any of it as a starting position for your own numbers rather than a quote.
None of it covers additions or a wet room. Moving a bathroom into a new footprint, or a curbless linear-drain build that needs the floor structure dropped, is a different job with different risk.
One thing worth knowing about the calendar: on Google Trends, US interest in "bathroom remodel cost" ran 96 to 100 across February and early March 2026 against 52 to 59 in October 2025. That index is relative interest rather than search volume, so read it as shape, not size - the shape says the bids you write in winter decide the spring.
The trap is not really about bathrooms. Any job where the cost lives in the connections instead of the floor area punishes a per-foot quote, which is the same reason decks get underbid on the substructure. BidWalk builds the line items while you are still standing in the room, looking at the wet wall and counting the wall tile instead of the floor.
