THE SHORT ANSWER
Build a bathroom renovation estimate around the existing layout, demolition limits, fixture allowances and measured finishes. Separate what the customer selects from what your crew installs, then record the assumptions that could change the price.
This guide follows a fictional 80 sq. ft. bathroom refresh in Toronto, Ontario. The linked bathroom renovation PDF example shows the scope and 7 separate costs in Canadian dollars. Treat it as a worked document, then use measurements, supplier quotes and labour inputs from your own project.
1. Freeze the layout before pricing finishes
Confirm whether the toilet, vanity and tub stay in their current positions. A refresh within the same footprint is a different estimate from a layout change. Sketch the agreed scope and list the fixtures to remain so the customer can see what the price assumes.
2. Separate allowances from installation
Give the vanity, faucet and tile their own material allowances. Put installation labour on separate lines. If the customer chooses a more expensive fixture, the material difference is visible without silently changing the labour amount. Record who orders, receives and checks the products.
3. Measure the actual surfaces
Use the measured floor area for installation and a separately identified purchasing quantity for materials. In this example, 80 square feet are installed and 88 square feet of tile are allowed for purchase. That extra eight feet is an example assumption to review against the layout, cuts and chosen tile.
4. Make hidden conditions a decision point
Describe how damaged subfloor, concealed leaks or unsuitable wall surfaces will be handled if discovered. Excluding unknown repairs is useful only when the customer understands that additional work requires a revised scope and price before it proceeds.
Review the Canadian project address
For the 80 sq. ft. bathroom refresh in Toronto, Ontario, the example uses the measured trade units shown in its PDF. Residential jobs may mix square feet, linear feet, counts and supplier units; keep each line’s measurement basis visible. Confirm site access, product selections and existing conditions in person. Check any trade or municipal requirements for the actual location, and record changes before issuing a final price. The figures are fictional CAD inputs, not a local price survey.
Describe which products the customer supplies and which the contractor supplies. State how any site condition outside the visible scope will be assessed and priced. Do not copy an allowance from another city or assume a sample’s tax entry establishes the treatment for this client.
Work through the bathroom renovation quantities
The matching PDF lets the client check each extension of quantity and unit rate. For this example, two useful checks are:
- Floor tile material allowance: 88 sq. ft. × C$6.80 = C$598.40.
- Floor tile installation: 80 sq. ft. × C$16.00 = C$1,280.00.
Adding all 7 lines gives a C$5,787.40 illustrative subtotal. The PDF records 0% tax and C$5,787.40 as its total, before any markup. These are chosen sample inputs, not prices observed in Toronto, Ontario. The measurement basis matters as much as the rate: a material purchase allowance may be larger than the installed area, while a fixture count is not interchangeable with hours of labour.
Check the scope before sending
- Confirm who supplies the tub, toilet and accessories.
- State which surfaces are tiled and which are painted.
- Record access, debris removal and protection requirements.
- List concealed repairs and layout changes outside the base scope.
Outside the illustrated scope: No wall relocation, new shower assembly, concealed water-damage repair or electrical service changes. Verify any required approvals separately.
Check the business and client names, property location, dates, quantities, unit rates and notes. Confirm tax, markup and any required approvals for the actual job. If selections or site conditions are unresolved, label the line as an allowance and explain how it will be updated.
Common questions
Should a bathroom estimate include fixture allowances?
Use an allowance when the final fixture has not been selected, and identify exactly which product cost it covers. Keep installation labour separate so a product upgrade can be priced clearly.
Is floor area enough to estimate a bathroom renovation?
No. Floor area helps with flooring, but fixture count, wall finishes, demolition and layout changes need their own quantities or scoped lines.
