The Bathroom Remodel Cost Calculator estimates what a bathroom remodel or renovation might cost in two ways. The quick estimate multiplies the floor area by a cost per square foot for your finish level and gives a ±20% range. The itemized mode adds up your own prices for the vanity, toilet, tub or shower, tile, electrical and labor, plus a contingency.
Bathroom Remodel Cost Calculator
Estimate the cost of a bathroom remodel or renovation — a quick estimate by size and finish level, or an itemized budget.
The cost-per-square-foot levels and item prices are illustrative defaults, not quotes. Replace them with local prices — costs vary widely by region, finish and whether plumbing is moved.
Formula
Quick estimate: Cost = A × rate × (1 + local adjustment); range = cost × 0.8 to cost × 1.2
Itemized: Total = (materials + labor) × (1 + contingency)
Where A = bathroom floor area in ft² and rate = example cost per ft² for the finish level.
How the Calculation Works
Step 1: Measure the bathroom floor (length × width).
Step 2: Pick a finish level and adjust for your local costs (e.g. +20% for high-cost cities).
Step 3: Or switch to itemized mode and enter each quote, then add contingency.
Variables Explained
| Finish level | Example rate in the calculator | Typical scope |
|---|---|---|
| Basic / budget refresh | $100/ft² | Replace fixtures and finishes in the same layout |
| Mid-range remodel | $250/ft² | New tile, vanity, tub/shower, lighting |
| High-end / luxury | $450/ft² | Custom tile work, premium fixtures, layout changes |
These are starting points to edit, not market averages.
Example Calculation
Quick estimate
Given: 8 × 5 ft bathroom (40 ft²), mid-range example rate $250/ft², no adjustment
Cost = 40 × 250 = $10,000; range $8,000–$12,000
Itemized (example prices)
Vanity $900 + toilet $350 + tub/shower $1,500 + faucets $450 + tile $1,200 + electrical $500 + accessories $300 = $5,200 materials
Labor $6,000 → subtotal $11,200
With 10% contingency: $12,320
What Drives Bathroom Remodel Cost
- Moving plumbing (toilet, shower drain) adds significantly compared with keeping the layout.
- Tile: amount of wall tile, tile type and pattern complexity.
- Fixture grade: vanity, tub, shower glass, faucets.
- Hidden problems found during demolition, such as water damage or outdated wiring.
- Local labor rates and permit requirements.
Frequently Asked Questions
How much does a bathroom remodel cost?
It depends on size, finish level and location. Use the calculator with local contractor quotes for a realistic figure.
How do I estimate bathroom remodel cost per square foot?
Divide a contractor’s quote by the floor area — or multiply your floor area by a local rate.
Why do small bathrooms cost so much per square foot?
Fixtures, plumbing and trades are needed regardless of size, so costs are concentrated in a small area.
How much contingency should I include?
Many homeowners set aside a reserve for surprises; the calculator uses 10% by default, which you can change.
Is a full bathroom remodel different from a refresh?
Yes — a refresh keeps the layout and most surfaces; a full remodel replaces everything down to the studs.
