Bathroom Remodel Cost Calculator: What It Does and How to Use It
This bathroom remodel cost calculator estimates the price of a full remodel, including demolition, fixtures, tile, vanity, lighting and labor. Enter the room size and finish level, add a layout change or freestanding tub if you want one, and get a low, typical and high price based on national 2026 averages.
- Measure the bathroom. Multiply length by width. A 5 × 8 ft hall bath is 40 sq ft.
- Choose a finish level. Basic refresh, midrange or upscale.
- Add a layout change. Tick it if the toilet, shower or sink will move.
- Add a freestanding tub. If you're adding a soaking tub.
- Enter your ZIP code or city. The estimate adjusts to prices in your state.
Bathroom Remodel Cost Formula: Step by Step
Range = base ± 13%
Extras = layout change ($2,500–$6,500) + freestanding tub ($900–$1,800)
Total = range + extras
Finish factors: basic refresh ×0.62, midrange ×1.0, upscale ×1.88. The fixed $8,400 covers the fixtures and plumbing every bathroom needs, which is why small bathrooms cost more per square foot.
Worked example: 50 sq ft midrange remodel.
Base = $8,400 + $107 × 50 = $13,750. Range ±13% = about $12,000 – $15,500.
Average bathroom remodel cost and cost per square foot
Every bathroom remodel has fixed costs that don't shrink with the room: a toilet, a vanity, a shower or tub, plumbing hookups, an exhaust fan and GFCI outlets. Tile, flooring and labor then grow with the floor area. That's why small bathrooms cost more per square foot than large ones, even though their total is lower.
| Bathroom size | Per sq ft | Total |
|---|---|---|
| Half bath, 25 sq ft | $386 – $500 | $9,650 – $12,500 |
| 5 × 8 ft, 40 sq ft | $275 – $358 | $11,000 – $14,300 |
| 5 × 10 ft, 50 sq ft | $240 – $310 | $12,000 – $15,500 |
| 10 × 10 ft, 100 sq ft | $166 – $216 | $16,600 – $21,600 |
| Primary, 150 sq ft | $142 – $184 | $21,300 – $27,600 |

Small bathroom remodel cost
A small bathroom of 35 to 50 square feet, like a standard 5 × 8 ft hall bath, typically costs $6,900 – $8,800 for a basic refresh and $11,000 – $14,300 at midrange. Small rooms reward smart choices: a 60-inch tub or shower, a wall-hung vanity and large-format tile make them feel bigger without adding much cost.
Master bathroom remodel cost
A primary (master) bathroom of 120 to 200 square feet usually has a double vanity, a separate shower and often a soaking tub. Expect about $21,300 – $27,600 for a midrange 150 sq ft primary bath and $40,000 – $51,900 with upscale finishes. Layout changes, like moving the toilet or turning a tub into a walk-in shower, add $2,500 to $6,500.
Half bath remodel cost
A half bath, or powder room, has only a toilet and a sink, so there's no shower to build or waterproof. A 20 to 30 sq ft half bath typically costs $6,050 – $7,700 for a basic refresh and $9,650 – $12,500 at midrange. Wallpaper, a statement vanity and better lighting make the biggest visual difference for the money.
Shower remodel cost and tub-to-shower conversion
The shower is the most expensive single part of most remodels: a complete shower remodel averages about $8,044. A prefab tub-and-shower combo unit is far cheaper at around $1,258 installed. Converting a tub to a walk-in tile shower means removing the tub, building a new shower pan with a waterproofing membrane, tiling and adding glass, and if the drain has to move, the layout-change cost applies too. Curbless showers cost more because the floor has to be recessed.
Walk-in shower installation cost
A walk-in shower costs about $12,000 on average, with most projects between $4,000 and $20,000. The finish level makes the biggest difference:
| Type | Typical cost |
|---|---|
| Basic prefab shower | $4,000 – $7,000 |
| Midrange tiled shower | $8,000 – $13,000 |
| High-end custom shower | $14,000 – $20,000+ |
Bathtub replacement cost
Replacing just the bathtub costs about $5,929 on average, usually between $2,104 and $9,757 including labor and removal. The tub itself ranges from $200 to $800 for a standard alcove tub to $2,000 to $3,000 for a freestanding tub, and much more for walk-in or clawfoot models. Removing a lightweight fiberglass tub can cost as little as $50 to $100, while cast iron takes more labor.
Bathroom renovation cost breakdown
| Item | Average cost |
|---|---|
| Shower (complete remodel) | $8,044 |
| Plumbing work | $5,545 |
| Vanity and cabinets | $2,929 |
| Tile | $1,326 |
| Tub-and-shower combo | $1,258 |
| Freestanding tub | $1,123 |
| Flooring | $1,114 |
| Toilet, installed | $467 |
| Electrical | $456 |
| Countertop | $332 |
Labor makes up a large share of every line, because a remodel involves demolition, plumbing, electrical, waterproofing, tile setting and finish carpentry, often by several trades.
How to save on a bathroom remodel
- Keep the layout. Leaving the toilet, shower and sink where they are avoids the biggest plumbing costs.
- Refinish instead of replacing. Reglazing a tub or painting a vanity costs a fraction of new ones.
- Spend on what you touch. Put money into the shower valve, faucet and vanity top, and save on wall tile outside the wet area.
- Buy standard sizes. Stock vanities, a 60-inch tub and common tile sizes cost less and install faster.
- Do the easy parts yourself. Demolition and painting are DIY-friendly; leave plumbing, electrical and waterproofing to licensed pros.
- Get three quotes and compare them line by line against your estimate.
Does a bathroom remodel add value?
A midrange bathroom remodel recovers roughly 80% of its cost in added home value, one of the better returns among home projects. It pays off most when the current bathroom is clearly dated, when it's the only full bath, or when you plan to sell within a few years.
Bathroom addition cost
Adding a new bathroom costs far more than remodeling one, because it needs new plumbing lines, wiring, ventilation and often framing. Most bathroom additions cost $21,000 to $49,000:
| Type | Typical cost |
|---|---|
| Half bath (20–25 sq ft) | About $18,000 |
| Full bath (40–60 sq ft) | About $21,000 |
| Primary bath (100–200 sq ft) | $28,000 – $42,000 |
Converting existing space, like a closet or part of a bedroom, can cost up to 50% less than building out. Labor typically makes up about 40% to 55% of a bathroom addition.
How to budget a bathroom renovation
- Start with your estimate. Use the bathroom remodel cost calculator above at the finish level you want.
- Price the big items first. The shower, plumbing and vanity usually take the largest share of the budget.
- Decide what stays. Keeping the layout and reglazing a tub instead of replacing it frees up money for finishes.
- Keep a contingency. Old bathrooms often hide water damage or outdated plumbing behind the walls.
- Compare written quotes. Get two or three bathroom remodel estimates and check them line by line against your budget.
