Bathroom Remodel Cost Calculator
Enter your bathroom size, remodel scope and tier to see an itemized cost range — materials and labor separated on every line, with state labor rates and a contingency line included. A planning estimate, not a quote.
Add your project details
Choose size, scope and tier, then select “Calculate my estimate”. Your itemized cost range appears here.
Results are always a range, never a single number, with materials and labor shown separately for every line.
How to use this calculator
1. Measure your bathroom
Multiply length by width in feet for the floor area. Most full bathrooms are 35–100 sq ft; a small bathroom remodel usually means 35–50 sq ft with the same fixtures in the same places.
2. Pick the scope honestly
Scope is the biggest cost driver. A cosmetic refresh only touches surfaces; a partial remodel redoes the wet area and floor; a full gut remodel rebuilds everything to the studs. Choosing a smaller scope than you actually plan is the most common budgeting mistake.
3. Choose a tier, then read the range
Tier sets the specification of everything that gets replaced — tub, tile, vanity and fixtures. Read the result as a range: budget to the high end, and keep the contingency line in place for what the walls might hide.
4. Compare with contractor quotes
Take the itemized table to your quote meetings. If a bid lands far outside the range, ask which lines differ — the itemization makes that conversation specific instead of vague.
Every allowance stays visible
For each line, materials = national material band × quantity; labor = national labor band × quantity × state wage ratio; fees = fee band × quantity (no wage adjustment). State wages are a proxy, not ZIP pricing or contractor billing. National material ranges. State adjustments apply to labor only.
subtotal = sum of line items (materials + labor + fees)
contingency = subtotal × contingencyRate
total = subtotal + contingency
One rate for both endpoints: default 10%, allowed 10%–15%. There is no separate widening or uncertainty allowance: the total on screen is exactly the displayed line-item subtotal plus the displayed contingency (the F1.2 identity). Keep internal precision and round only for display. Any necessary missing rate or state wage means all four monetary totals are null; never substitute knownSubtotal.
Full gut remodels add one disclosed line before the subtotal: general conditions & contractor markup, charged on the trade subtotal at the published Homewyse band (13% at the low end, 22% at the high end). It is a sourced model input, never folded into any trade line. Partial and cosmetic scopes are trade-by-trade work and carry no general-contractor layer; deck estimates never carry it.
Tier specifications
Tier is the specification of the materials and fixtures that get installed. It combines with whichever tub and shower arrangement you choose — the calculator prices the combination, not a fixed product list.
Budget
Acrylic alcove tub/shower, ceramic floor, painted walls, stock single-sink vanity with integral top, standard toilet. No custom tile. Sensible for rentals, guest bathrooms and first-phase refreshes.
Midrange
Alcove tub with ceramic surround, porcelain floor, painted walls, stock single-sink vanity with integral solid-surface top, standard toilet. No premium stone or custom cabinetry. The tier most full remodels are actually built at.
Upscale
Custom hardwood double-sink vanity with stone top, upgraded toilet, stone floor and dry-wall tile, tiled shower and soaking tub.
Upscale estimates are temporarily unavailable while high-end pricing data is re-verified. Budget and Midrange estimates are unaffected.
Typical bathroom remodel costs by size
Full gut remodel, Midrange tier, tub + shower combo, national average, 10% contingency — calculated from the same data package as the calculator above (Updated November 2026; sources: Fixr, Angi, Cost vs Value, BLS OEWS).
| Bathroom size | Typical layout | Total estimate range |
|---|---|---|
| 35 sq ft | Small full bathroom | $11,008 – $26,581 |
| 50 sq ft | Compact family bathroom | $12,285 – $28,372 |
| 60 sq ft | Typical full bathroom | $13,136 – $29,568 |
| 75 sq ft | Large full bathroom | $14,413 – $31,360 |
| 100 sq ft | Primary-suite bathroom | $16,539 – $34,348 |
| 150 sq ft | Spa-style primary bathroom | $20,796 – $40,323 |
Typical costs by scope at 60 sq ft
| Scope · tier · arrangement | Total estimate range |
|---|---|
| Cosmetic refresh · Budget · keep existing tub/shower | $1,237 – $3,670 |
| Partial remodel · Budget · tub + shower combo | $4,535 – $11,693 |
| Full gut remodel · Midrange · tub + shower combo | $13,136 – $29,568 |
These are planning ranges from published national cost data, not prices anyone has paid for a specific home. Your state selection in the calculator adjusts the labor portion for where you live.
Small bathrooms: where the money goes
A small bathroom remodel cost calculator has to be honest about one thing: small rooms are not proportionally cheap. The expensive parts of a bathroom — plumbing, waterproofing, a tub or shower, a toilet, ventilation — barely shrink with floor area, so a 35 sq ft full remodel still carries most of the fixed costs of a 60 sq ft one. What does shrink is tile, flooring and paint. Keeping the layout unchanged is the single biggest saving in a small bathroom, followed by keeping the existing tub and refinishing surfaces instead of replacing them.
Planning a bathroom remodel budget
Treat this page as your bathroom remodel budget calculator before you spend anything: run the project you actually want, note the high end of the range, and hold the contingency at 10–15% — older bathrooms regularly hide subfloor or plumbing work that no calculator can see. If the total is over budget, the levers that matter, in order, are scope (gut → partial → cosmetic), layout (moving plumbing is its own priced line), and tier. Trimming contingency or hoping materials come in low is how remodels stall halfway.
Frequently asked questions
How accurate is this bathroom remodel cost calculator?
It gives a planning estimate range built from published cost data, not a quote for your exact bathroom. Real bids move with site conditions, local labor markets and the specific products you pick — which is why every result here is a range with materials and labor itemized, and why you should still get 2–3 written quotes from local contractors before you commit.
Why does my state only change the labor cost?
Materials are priced from national ranges that do not vary much by state, while labor rates vary a lot. The state adjustment therefore multiplies labor only, using the ratio of your state’s average construction wage to the national average (BLS OEWS, SOC 47-0000). Materials always use national price ranges.
What is the contingency line in the estimate?
Contingency is a separate allowance for the surprises remodels tend to hide — tired subfloors, old plumbing, out-of-square walls. It is calculated on the itemized subtotal, defaults to 10%, and you can raise it to 15%. It is shown as its own line so the total always adds up exactly.
What is not included in the estimate?
Structural repairs; hidden damage such as mold or rot; asbestos abatement; septic or well work; and work outside the bathroom footprint. Permits and inspections are priced as their own line when your scope includes them. Anything an older home might hide should be budgeted on top of the estimate.
Can I use this as a bathroom remodel budget calculator?
Yes — that is exactly its job before you talk to contractors. Run your realistic scope and tier, keep the contingency at 10–15%, and treat the high end of the range as your planning ceiling. If the range is above your budget, step down a tier or split the work into phases instead of trimming the contingency.
