Plan a bathroom remodel with an estimate built around the details you control. This calculator turns your scope and assumptions into a clear main result, then shows the supporting quantities or costs behind it. Replace the sample values with measurements, quotes, and product information from your project. Use the result to compare scenarios and prepare questions—not as a substitute for a site visit, code review, contractor proposal, or appraisal.
Crew schedule days = total crew-hours ÷ (crew size × hours per workday).
Crew-hours measure total labor effort, not elapsed calendar time. The schedule estimate assumes the listed crew can work concurrently without interruptions.
Planning estimate only. Permits, inspections, drying time, trade sequencing, demolition surprises, and material delays can extend the calendar schedule.
For 80 sq ft at 0.65 hour per sq ft and a 1.15× complexity factor, estimated labor is 59.8 crew-hours. A three-person crew working eight-hour days would need about 2.5 working days.
Use finished-scope measurements, not the home's total area. Measure each relevant surface and keep the units consistent with the input labels.
Use current written quotes and product coverage data whenever available. Defaults are examples for exploring scenarios, not market prices.
Intermediate math keeps full precision. Displayed results are rounded for readability, and package or sheet counts are rounded up when whole units must be purchased.
Only indirectly through the inputs and contingency or complexity setting. Moisture, structural damage, access limits, and code upgrades should be estimated separately.
No. It is a planning estimate. Confirm scope, code requirements, quantities, costs, value assumptions, and scheduling with qualified local professionals.
| Input | Meaning | Unit |
|---|---|---|
| Floor area | Measured finished area | sq ft |
| Labor intensity | Base effort before complexity | hr/sq ft |
| Complexity | Scope adjustment | multiplier |
| Crew size | Concurrent workers | people |
