THE ESTIMATING ANSWER
Estimate shower wall tiling by measuring the defined three shower walls, separating product allowances from labour and setting out the work sequence and exclusions. This fictional Sheffield example uses 7 itemised lines totalling £4,098.42; its exact quantities and rates appear in the paired app PDF.
The worked job is three shower walls in Sheffield. The written scope is: Retile three sound shower walls within the existing enclosure, including substrate preparation, waterproofing allowance, tile setting and grout. Fixtures stay in place. 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
Retile three sound shower walls within the existing enclosure, including substrate preparation, waterproofing allowance, tile setting and grout. Fixtures stay in place. Measure each wet wall separately and record niches, corners and tile size so purchasing and installed areas are distinct. 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 each wet wall separately and record niches, corners and tile size so purchasing and installed areas are distinct. 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
Keep tile, edge trim and waterproofing products visible as separate selected or provisional items. This example has 7 distinct lines, including wet-area protection, existing tile removal, substrate and waterproofing allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Choose before pricing: Keep tile, edge trim and waterproofing products visible as separate selected or provisional items. 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
Allow demolition, substrate inspection and curing stages before the screen is refitted. 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: Allow demolition, substrate inspection and curing stages before the screen is refitted. 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
Unsound backing discovered after tile removal requires a separate substrate repair decision. The example excludes shower tray replacement, plumbing alteration or hidden framing repair. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: Unsound backing discovered after tile removal requires a separate substrate repair decision. 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, Existing tile removal is 8.8 sq m × £68.90 = £606.32; Substrate and waterproofing allowance is 8.8 sq m × £103.35 = £909.48. 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 |
|---|---|---|---|
| Wet-area protection | 1 lump sum | £120.00 | £120.00 |
| Existing tile removal | 8.8 sq m | £68.90 | £606.32 |
| Substrate and waterproofing allowance | 8.8 sq m | £103.35 | £909.48 |
| Tile material allowance | 9.8 sq m | £60.30 | £590.94 |
| Tile setting labour | 8.8 sq m | £163.60 | £1,439.68 |
| Edge trim and grout | 1 lump sum | £256.00 | £256.00 |
| Clean-up and screen refit allowance | 1 lump sum | £176.00 | £176.00 |
| Illustrative total | £4,098.42 | ||
Adding the 7 exact line amounts gives £4,098.42. 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
Retile three sound shower walls within the existing enclosure, including substrate preparation, waterproofing allowance, tile setting and grout. Fixtures stay in place.
Outside this example: No shower tray replacement, plumbing alteration or hidden framing 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.
