Bathroom Remodel Cost Calculator

Most bathroom remodels in the US cost $6,000 to $18,000, with a national average of about $12,000 (Fixr, 2026). A contractor-managed mid-range remodel of a 5 × 7 ft bathroom costs about $26,138, and an upscale remodel that enlarges the room to 100 sq ft about $81,612 (Cost vs Value 2025). Scope matters more than size: a cosmetic refresh that keeps the shower and layout costs a fraction of a gut remodel.

Typical sizes are 12–30 sq ft for a powder room, 40–60 sq ft for a full bath and 75–100 sq ft for a primary bath (Bob Vila (opens in a new tab)). Cost rises with size more slowly than area does, because the toilet, vanity and shower cost about the same in any room. That is why small bathrooms cost more per square foot.

1. Line items from dated sources. Each item has a national installed range from Fixr, This Old House, HomeAdvisor or Angi. Tile is priced per square foot of floor or wall; the tub or shower by the option you pick.
2. Scope sets the point in each range. Cosmetic prices items from the low end to the middle of their range, mid-range from a quarter to three quarters, upscale from the middle to the top (low, typical, high: e.g. mid-range at 25%, 50% and 75% of each range). Upscale tile switches from ceramic to natural stone.
3. The total is the sum of the items you switch on. Item averages leave out a general contractor’s project management, overhead and profit, and drywall, paint, trim and clean-up. Cost vs Value 2025 prices a full contractor-managed job, so it runs higher; the table below sets the two side by side rather than forcing them to agree.
4. Some DIY removes the labor share (50%, Fixr’s average) from demolition, the vanity, the toilet and faucets. Tile, plumbing, electrical and the shower stay with a pro.
5. Local cost adjustment is your own number. We found no verified published US regional multiplier for bathroom remodels, so the calculator stays at national averages unless you set the difference you see in local quotes.

The materials and labor split assumes labor is 50% of each pro-installed item (Fixr: 40% to 65%). Resale value applies the Cost vs Value 2025 national recoup share for your scope to your estimate.

The shower or tub and the vanity take about half the budget. Labor is the other big factor: 40% to 65% of the total. Moving plumbing, upgrading from ceramic to stone and hiring a designer push a project from mid-range to upscale.

5 × 10 ft full bath, mid-range, hired out

A new tub, tile floor and walls, vanity with top, toilet, faucets, lighting, demolition and permits, each installed by a pro, come to about $14,000 ($10,400 to $17,600), or $280 per sq ft.

The same bathroom with some DIY

Doing the demolition and installing the vanity, toilet and faucets yourself brings it to about $10,400, a saving of $3,600.

Powder room, cosmetic refresh

A 20 sq ft powder room with a new vanity and top, toilet, faucet, light and fan and a tile floor costs about $4,000 ($2,600 to $5,400).

80 sq ft primary bath with a tub-to-shower conversion

At mid-range finishes, converting the tub to a shower and redoing the vanity, tile and fixtures comes to about $19,100 ($13,500 to $24,700).

• Keep the layout. Moving a drain and the shower valve adds $1,600 to $2,300 before any finishes (This Old House).
• Choose a prefab shower. A kit costs $700 to $3,000; a tiled walk-in shower $6,000 to $12,000.
• Use ceramic tile. Installed ceramic runs $10–$25 per sq ft against $40–$65 for natural stone (Angi, via HomeLight).
• Do the simple parts yourself. Demolition and swapping a vanity, toilet or faucet are the usual DIY jobs; leave wiring, plumbing and waterproofing to licensed pros.
• Plan for surprises. Fixr sets aside about 5% as a cushion; This Old House recommends 10 to 20% for hidden water damage or rot.

Fixr gives an average of 2 to 4 weeks, and 2 to 12 weeks for most projects. Cosmetic work with no plumbing or wiring changes is the quickest; moving fixtures, permits and inspections, and made-to-order items such as glass doors or stone tops add weeks.

A bathroom remodel adds resale value, but less than it costs. Mid-range projects return the largest share: 80% nationally, against 42% for an upscale remodel (Cost vs Value 2025).
