Bathrooms are the priciest room in the house per square foot. A cosmetic refresh runs about $160 per sq ft ($6,400 for a 40 sq ft bath), a midrange gut remodel about $700 per sq ft ($28,000), and upscale spa work $900 and up. Here's what drives the difference and where budgets quietly fail.
Size and scope set the bill. National installed ranges for 2025-26:
| Project | Low | Typical | High |
|---|---|---|---|
| Powder room refresh (20 sq ft) | $2,400 | $3,200 | $4,400 |
| Small bath refresh (40 sq ft) | $4,800 | $6,400 | $8,800 |
| Midrange gut (35–50 sq ft) | $19,250 | $24,500–$35,000 | $44,000 |
| Primary bath gut (60–100 sq ft) | $33,000 | $42,000–$70,000 | $88,000 |
| Upscale primary (~100 sq ft) | $75,000 | $90,000 | $115,000 |
| Add a new bathroom (existing space) | $25,000 | $40,000 | $60,000 |
Remodeling magazine's Cost vs. Value Report anchors the middle of those bands, with a 35 sq ft midrange remodel near $25,000 and a 100 sq ft upscale remodel near $80,000 in its latest editions.

Bathroom Remodel Cost Calculator →The tub or shower zone can consume a third of the budget by itself. A custom tile shower adds $3,000 to $8,000 over a standard insert, and every dollar of it hides behind waterproofing, slope, and labor: cement board or foam board, a sealed pan or linear drain, months-of-moisture membrane systems, then tile set and grouted on curved and vertical surfaces.
The trades stack on top. Plumber, electrician, HVAC (that exhaust fan has to vent outside), tile setter, painter, and glass installer each mobilize for a day or two in a room you can't use while they wait for each other. Labor typically claims about half of a bathroom budget, more than in any other room.
Converting a tub to a walk-in shower runs $2,500 to $6,000, with most near $4,000 for a tiled unit with a glass panel. It's one of the most popular bathroom projects in the country, and the value math depends on one question: does another tub remain in the house?
Families with young kids (and many buyers) want at least one tub. Keep or add a tub somewhere, and converting the primary bath's tub to a shower is usually a value-neutral or value-positive move. Remove the last tub and you've narrowed your future buyer pool.
Done well, a refresh plus a reglaze plus lighting can read as a remodel for a quarter of the gut price. Our flooring calculator and paint calculator cover the two DIY-friendliest lines if you're doing part of the work yourself.
Plan on about a week for a refresh, 3 to 6 weeks for a midrange gut, and 6 to 12 weeks for upscale work with custom glass and slabs. Permits are usually required for plumbing, electrical, and ventilation changes and typically cost $100 to $1,000; pull them properly, because unpermitted plumbing turns up in every resale inspection.
Yes, with discipline. A $10,000 refresh keeps the tub, tile, and layout while swapping the vanity, toilet, lighting, mirror, hardware, and paint, and possibly regrouting or reglazing instead of replacing tile. You leave about $1,000 to $2,000 as contingency and skip moving anything plumbed.
Waterproofing and tile. Every wet surface needs a waterproofing system behind it, tile is pure skilled labor, and plumbing, electrical, and ventilation trades all work in sequence in the smallest room of the house. Labor typically takes about half of a bathroom budget.
A midrange bathroom remodel recoups roughly 60% to 70% of cost at resale per Remodeling's Cost vs. Value Report, which beats major kitchen remodels. Refreshes and midrange work return more, percentage-wise, than upscale remodels.
