THE ESTIMATING ANSWER
For one three-fixture bathroom, start with a defined scope and measurement basis. Set out each fixture centre, pipe route, chase, floor level and connection point from the selected layout. Identify pipe, fittings and fixture-specific connection allowances without assuming final trim products. Price the listed tasks separately and state the condition that would require a revision: A layout change or unknown existing services alters pipe runs and access.
This guide uses a fictional project in Brandon, Manitoba: One three-fixture bathroom. Its matching estimate and PDF give each scope decision a visible CAD cost line. Use the document to understand the structure; verify the actual building, product schedule, labour and supplier inputs before preparing a client quote.
1. Define the measured job
Rough in water and waste connections for a toilet, basin and shower in an accessible room before finishes, against a confirmed fixture layout. Set out each fixture centre, pipe route, chase, floor level and connection point from the selected layout. Record the measurements and existing condition in the estimate before turning quantities into line items. The scope should make clear why this is a separate project from a broader renovation or maintenance quote.
Measurement basis: Set out each fixture centre, pipe route, chase, floor level and connection point from the selected layout.
2. Build a product and labour schedule
Identify pipe, fittings and fixture-specific connection allowances without assuming final trim products. This example has 7 distinct lines, including layout and service survey, access and chase preparation, water pipe allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Selections to confirm: Identify pipe, fittings and fixture-specific connection allowances without assuming final trim products.
3. Sequence the work and handoffs
Coordinate wall framing and waterproofing handoff before concealing work. Show which task depends on access, a selected product or another trade. If that dependency is still open, label the price preliminary and identify the information needed before a firm quote.
Work sequence: Coordinate wall framing and waterproofing handoff before concealing work.
4. Set a change boundary
A layout change or unknown existing services alters pipe runs and access. The example excludes final fixture supply, tiling, structural alterations or concealed service upgrade. Record the discovery, agree the revised work and update the estimate before adding it to the job.
If the job changes: A layout change or unknown existing services alters pipe runs and access.
Review the Canadian job address
Verify the existing water, waste and fixture connections on site. Confirm who handles any required trade work, approvals and inspections for this address; this fictional document does not decide them.
The water pipe allowance line uses 85 linear ft., approximately 25.91 m. Check the route, cuts and supplier unit before setting a real quantity. The example amounts are fictional CAD document inputs, not current rates for Brandon, Manitoba or another community. A site visit and current supplier information are needed to replace them.
Work through the itemized calculation
Check each extension of quantity and rate in the paired PDF. Two lines from this project are:
- Water pipe allowance: 85 linear ft. × C$17.00 = C$1,445.00.
- Water rough-in labour: 20 hours × C$115.00 = C$2,300.00.
Adding all 7 rounded line amounts gives C$7,880.00. The PDF shows 0% tax and the same total before any markup. The sample shows 0% tax only to make the arithmetic visible. Determine any applicable GST, HST or PST and markup for the actual work before sharing a quote.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Layout and service survey | 1 job | C$335.00 | C$335.00 |
| Access and chase preparation | 1 job | C$515.00 | C$515.00 |
| Water pipe allowance | 85 linear ft. | C$17.00 | C$1,445.00 |
| Drain pipe and fitting allowance | 1 job | C$865.00 | C$865.00 |
| Water rough-in labour | 20 hours | C$115.00 | C$2,300.00 |
| Waste rough-in labour | 16 hours | C$125.00 | C$2,000.00 |
| Test and inspection preparation | 1 job | C$420.00 | C$420.00 |
| Illustrative subtotal | C$7,880.00 | ||
Scope and pricing boundaries
Rough in water and waste connections for a toilet, basin and shower in an accessible room before finishes, against a confirmed fixture layout.
Outside this example: No final fixture supply, tiling, structural alterations or concealed service upgrade.
Keep the product allowance, installation work and any unresolved condition visible as separate decisions. If access or the selected product changes, update the affected quantity or rate and explain the revision before the client relies on the estimate.
Before you send the estimate
- Set out each fixture centre, pipe route, chase, floor level and connection point from the selected layout.
- Identify pipe, fittings and fixture-specific connection allowances without assuming final trim products.
- Coordinate wall framing and waterproofing handoff before concealing work.
- A layout change or unknown existing services alters pipe runs and access.
Check the business, client, property, dates, line extensions and notes. The bathroom fixture plumbing rough-in PDF example shows one way to present them. Its short PDF note lists the brief's scope exclusions; the fuller project limits above should guide your own scope.
