THE ESTIMATING ANSWER
Estimate bathroom vanity unit replacement by measuring the defined one existing basin unit position, separating product allowances from labour and setting out the work sequence and exclusions. This fictional Leeds example uses 7 itemised lines totalling £1,372.00; its exact quantities and rates appear in the paired app PDF.
The worked job is one existing basin unit position in Leeds. The written scope is: Remove a single existing basin unit, install a selected replacement in the same position, reconnect the existing services and finish exposed wall edges. Its matching itemised example shows how that description becomes quantities, allowances and a PDF. These figures are fictional inputs for learning the method, so check the real site, specification and supplier or subcontractor costs before quoting.
1. Define the measured job
Remove a single existing basin unit, install a selected replacement in the same position, reconnect the existing services and finish exposed wall edges. Measure cabinet width, depth, pipe entry points and floor clearance rather than relying on the old unit label. 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.
Measure for this job: Measure cabinet width, depth, pipe entry points and floor clearance rather than relying on the old unit label. Record the measured basis next to the relevant cost lines, since a room count, fitted length and purchased product quantity may each use a different unit.
2. Build a product and labour schedule
Separate the cabinet and top allowance from taps and fittings, connection parts and installation labour. This example has 7 distinct lines, including site measure and protection, existing basin unit removal, basin unit and top allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Choose before pricing: Separate the cabinet and top allowance from taps and fittings, connection parts and installation labour. Keep a named allowance when the selection is open, and replace it once the actual product and delivery terms are known.
3. Sequence the work and handoffs
Confirm product delivery and shutoff access before removing the existing unit. 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.
Plan the handoffs: Confirm product delivery and shutoff access before removing the existing unit. State which stage needs access or inspection before the next can begin, especially if a concealed condition might stop the work.
4. Set a change boundary
Unexpected pipe position or damaged wall behind the cabinet requires a revised connection or finish line. The example excludes plumbing relocation, new floor covering or concealed water-damage repair. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: Unexpected pipe position or damaged wall behind the cabinet requires a revised connection or finish line. If this happens, write down the revised quantity and responsibility before adding an item to the customer estimate.
Worked project calculation
The paired PDF has 7 cost lines. For example, Site measure and protection is 1 lump sum × £76.00 = £76.00; Existing basin unit removal is 1 each × £116.00 = £116.00. Each amount is the stated quantity multiplied by its unit rate. Recheck whether a line describes installed work, a material purchase allowance or a distinct visit before changing its quantity.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Site measure and protection | 1 lump sum | £76.00 | £76.00 |
| Existing basin unit removal | 1 each | £116.00 | £116.00 |
| Basin unit and top allowance | 1 each | £552.00 | £552.00 |
| Tap and waste parts allowance | 1 set | £168.00 | £168.00 |
| Set and secure basin unit | 1 each | £224.00 | £224.00 |
| Reconnect and leak check | 1 lump sum | £140.00 | £140.00 |
| Wall touch-up and disposal | 1 lump sum | £96.00 | £96.00 |
| Illustrative total | £1,372.00 | ||
Adding the 7 exact line amounts gives £1,372.00. The PDF uses a 0% tax input and no markup solely to display this arithmetic. Decide the appropriate tax, overhead and profit treatment for an actual job; the fictional rates are not local averages or price recommendations.
Scope and price boundaries
Remove a single existing basin unit, install a selected replacement in the same position, reconnect the existing services and finish exposed wall edges.
Outside this example: No plumbing relocation, new floor covering or concealed water-damage repair.
The role in this brief is refurbishment contractor. Confirm who supplies the selected products, makes the site safe, removes waste and signs off the work. Where opening up reveals a different condition, document it and issue a revised scope and price rather than silently extending the base estimate. Also check access, drying or curing time, and the client handoff described in the work sequence.
