Methodology & sources

What this is: a planning-range bathroom calculator informed by Kohler / Toto / Delta / Moen manufacturer pricing, HomeGuide, HomeAdvisor, Homewyse, and licensed cost-estimating references.

Size scaling: demo, paint, and floor-tile labor scale per square foot of bathroom area. Plumbing/electrical rough-in scale by layout type (powder/three-piece/master) and fixture relocation scope.

Labor is modeled from per-unit installed rates with a crew-rate sanity check ($75-$140/crew-hr loaded billing rate), informed by BLS OEWS 47-2152 (Plumbers / Pipefitters) and 47-2031 (Carpenters).

For a typical 3-piece full bath (50 sf), the installed planning band runs $14,866 to $25,710 nationally before regional adjustment. In our simulations, about 35% of these projects hit “rotted / water-damaged subfloor under tub or shower”, typically adding $500–$3,000.

Bathroom remodel cost by size

A bathroom’s cost is driven far more by what is in it than by its floor area, so each row sets the layout and the bathing fixture as well as the size. Vary only the square footage and a powder room prices like a full bath, which is not a useful answer.

Bathroom remodel cost by size: installed cost range for each size, produced by this calculator's own engine
BathroomInstalled rangeRelative
Powder room~20 sq ft · toilet + vanity, no bathing $7,701 – $13,403
Small full bath~35 sq ft · prefab shower $12,572 – $21,892
Standard full bath~50 sq ft · acrylic tub/shower $12,858 – $22,345
Large bath~80 sq ft · tiled shower + glass $17,707 – $30,540

Planning ranges at national average pricing, not contractor quotes. Enter your ZIP in the calculator above for a figure tuned to your area — these rows use the same engine and the same assumptions.

What moves this price the most

Vary one input across its full range while holding everything else at the typical scenario, and this is how far each choice can move the installed estimate — measured by running the calculator's own engine. The widest bars are where your decisions matter most; the figures show the cheapest-to-priciest span each input creates on its own.

  • Wall / shower tile (sq ft)$18,350–$32,250
  • Shower footprint (sq ft)$20,300–$27,900
  • Bathroom area (sq ft)$19,350–$26,850
  • Floor tile (sq ft)$19,400–$26,050
  • Layout type$17,050–$23,500
  • Plumbing rough-in$16,250–$20,300

A tornado view: each row varies a single input; a real project moves several at once, so totals aren't additive.

Where your bathroom budget goes

In a mid-range 3-piece remodel, tile and tile labor take roughly a quarter of the budget, fixtures (tub, shower, toilet, vanity) another quarter to a third, and plumbing plus electrical labor about a quarter — with demo, paint, the exhaust fan, and the permit splitting the rest. Tile is the swing item: wall and shower tile run $20–$35 per sq ft installed and floor tile $16–$28.

ScopeRangeWhat moves it
Powder-room refresh$4,800 – $8,400New vanity, toilet, floor, paint — no wet work
Mid-range 3-piece$14,900 – $25,700Tub/shower, tile, vanity — same layout
Full layout change$18,500 – $32,000Fixtures relocated, new rough-in, often a building permit
Master spa bath$28,100 – $48,700Double vanity, separate soaking tub + tile shower, heated floor

Tub, shower, or both?

The wet-area decision sets both the budget and the resale story:

  • Keep an acrylic tub ($706–$1,200 plus install) — the cheapest path, family-friendly, and the safe resale choice if it's the home's only full bath.
  • Tub-to-shower conversion — drop in an acrylic shower kit ($1,176–$2,000) for the budget route, or build a custom tile shower ($118–$200 per sq ft of footprint) with a frameless glass enclosure ($1,470–$2,500) for the spa version.
  • Soaking tub plus separate shower — master-bath territory; a cast-iron or deep soaking tub runs $2,059–$3,500 and you need the floor space and budget for both fixtures.

One resale caution: removing the only bathtub in the house to build a walk-in shower can hurt resale with families. If you have more than one bath, convert the secondary one and keep a tub somewhere.

The hidden cost: waterproofing and what's behind the wall

The tile you see is half a shower; the waterproofing you don't see is what keeps the wall from rotting. Modern code requires a continuous waterproof membrane behind wall tile — the old "tile over green drywall" approach fails inspection now, so a proper installation costs more than a quick one and is worth every dollar.

Other behind-the-wall surprises that move a bid: rotted subfloor under an old leaking tub, an undersized or missing exhaust fan (code wants ventilation to keep mold out), and relocating a vent stack when fixtures move. None of these show in a glossy before-and-after, but all of them show up on the invoice.

Frequently asked questions

How much does a bathroom remodel cost in 2026?

Powder room refresh: $4,800-$8,400. Mid-range 3-piece full bath (50 sq ft): $14,900-$25,700. Master spa bath (100+ sq ft, double vanity, separate tub + shower): $28,100-$48,700, with ultra-high-end finishes running past $60,000. Full layout change with fixture relocation adds 25-60% to plumbing/electrical labor.

What bathroom size should I budget for?

Powder rooms run 18-30 sq ft, standard 3-piece full baths 40-60 sq ft, and master baths 80-150+ sq ft. Demo, paint, and floor tile scale linearly with that area. Plumbing rough-in is more about layout (powder vs full vs master) and whether fixtures move.

How does fixture relocation affect cost?

Reusing existing rough-in (no relocation) is the cheapest. Relocating one fixture within 4-6 ft adds about 25% to plumbing labor. A full layout flip — multiple fixtures moved or the bath rotated — adds 60% or more, plus likely floor framing modifications and a building permit instead of a plumbing permit.

Effect of relocation?

None = baseline. Minor +25%. Full flip +60%, plus floor framing mods + building permit.

DIY vs pro?

Demo, paint, vanity install — DIY-friendly. Plumbing + electrical require licensed pros + permit in most jurisdictions.

How long?

Powder 3-5 days. Mid-range 2-3 weeks. Master spa 4-8 weeks. Add 1-2 weeks if structural mods.

How much does a small bathroom remodel cost?

A standard 3-piece full bath (40-60 sq ft) kept in the same layout runs $14,900-$25,700. A powder-room refresh - vanity, toilet, floor, and paint with no wet work - is $4,800-$8,400.

How much does it cost to convert a tub to a shower?

Typically $3,000-$12,000. A drop-in acrylic shower kit ($1,176-$2,000 plus install) is the budget route; a custom tile shower runs $118-$200 per sq ft of footprint plus a frameless glass enclosure at $1,470-$2,500.

What is the most expensive part of a bathroom remodel?

Tile work and fixtures usually tie for the lead. Custom tile showers run $118-$200 per sq ft of footprint installed, and relocating plumbing fixtures adds 25-60% to labor versus reusing the existing rough-in.

Common mistakes & questions

  • Skip the curb height check — code requires 2 in min curb on tile showers.
  • Wall tile applied before waterproofing — fails inspection in modern code.
  • Heated floor under tub or vanity — wasted $$. Mat only under walking floor.
  • Skip exhaust fan or undersized — humidity rots drywall + framing.
  • Glass shower without proper drainage — water tracks under glass to floor below.
  • Wrong vanity height for users — taller users prefer 36 in over 32 in.
  • Ask your contractor: waterproofing system spec (Schluter Kerdi, RedGard), framing reinforcement for grab bars, ventilation CFM, lead time on tile + glass.

When this estimate is wrong

  • Hidden water damage in subfloor / framing — adds $1-5k.
  • Asbestos vinyl flooring or vermiculite insulation — abatement adds $1-3k.
  • Steam shower or sauna additions — separate scope, $5-20k.
  • Custom millwork or built-in storage adds 30-100% on cabinetry budget.
  • Code triggers: GFCI, AFCI, vent stack, vent termination height.
  • HOA / condo plumbing-stack work needs board approval + plumbing engineering.
