Calculation assumptions

  • Scope is tagged cosmetic; changing scope alone never silently changes your entered prices. Compare saved scenarios for different scopes.
  • Contingency and tax are independently applied to the same pre-tax base; neither is compounded.
  • These are editable illustrative budgets, not verified contractor quotes.
  • Planning total before rounding: 13397.50 in selected currency.

How to use this calculator

  1. Choose cosmetic refresh or full renovation for the scenario label.
  2. Enter your measured bathroom area and your own costs for each line item.
  3. Save one scope scenario, change the amounts, and compare it to a second.

The calculation formula

Base subtotal = sum of eight cost categories. Total = base subtotal + subtotal × contingency% + subtotal × tax allowance%.

Worked example

If category allowances add to $11,650 and contingency is 15%, the total without additional tax is $13,397.50.

Assumptions and limitations

  • Scope selection does not imply a secretly applied price multiplier.
  • Waterproofing design and electrical/plumbing work require appropriate qualified professionals.

Actual project costs may be affected by supplier rates, material grade, labor market, location, disposal, site condition, access, permits, taxes, and schedule. All entered prices are yours to revise. See our methodology and disclaimer.

Frequently asked questions

Does full renovation automatically add costs?

No. Adjust the category allowances to match full-scope work and compare snapshots.

Are waterproofing materials included?

There is a dedicated editable allowance; suitability and installation must be professionally assessed.
