THE ESTIMATING ANSWER
For three shower walls, start with a defined scope and measurement basis. Measure each wet wall separately and record niches, corners and tile size so purchasing and installed areas are distinct. Keep tile, edge trim and waterproofing products visible as separate selected or provisional items. Price the listed tasks separately and state the condition that would require a revision: Unsound backing discovered after tile removal requires a separate substrate repair decision.
This guide follows three shower walls in Adelaide, South Australia. The matching itemised estimate and PDF show how the job brief becomes measured quantities and separate AUD amounts. The responsible role in this scenario is renovation contractor. Check the actual site, selected products, supplier figures and labour plan before issuing a client quote.
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. Put that measured basis beside the relevant PDF lines so area, fitted length and product purchase quantities stay distinct.
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. The fixture separates wet-area protection, existing tile removal and substrate and waterproofing allowance rather than hiding all work in one figure.
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. Note which stage needs access, a selected product or another trade before the next stage can be priced confidently.
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. Record the revised task and quantity before it changes the amount your client sees.
Review the Australian job
Verify the existing water and waste connections, access and selected fittings on site. Assign any specialist work and check approval requirements that apply to the actual address.
The existing tile removal line uses 8.83 m². Keep the site measurement and supplier's selling unit together; a material purchase allowance can differ from installed coverage. The amounts are fictional AUD inputs, not current prices for Adelaide, South Australia or another location.
Worked project calculation
The paired PDF has 7 cost lines. For example, Existing tile removal is 8.83 m² × A$127.00 = A$1,121.41; Substrate and waterproofing allowance is 8.83 m² × A$191.00 = A$1,686.53. Each amount comes from the stated quantity and unit rate, so you can trace the arithmetic back to the job scope.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Wet-area protection | 1 job | A$222.00 | A$222.00 |
| Existing tile removal | 8.83 m² | A$127.00 | A$1,121.41 |
| Substrate and waterproofing allowance | 8.83 m² | A$191.00 | A$1,686.53 |
| Tile material allowance | 9.75 m² | A$111.52 | A$1,087.32 |
| Tile setting labour | 8.83 m² | A$303.00 | A$2,675.49 |
| Edge trim and grout | 1 job | A$473.60 | A$473.60 |
| Cleanup and screen refit allowance | 1 job | A$325.60 | A$325.60 |
| Illustrative total | A$7,591.95 | ||
Adding every exact-cent line gives A$7,591.95. The PDF uses a 0% tax input only to make its fictional arithmetic visible. Confirm the GST treatment that applies to the actual job and set your own markup before sharing a client quote. A fictional rate is a document input, not a market quote or a recommended selling price.
Scope and pricing 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.
Separate product allowances, supply, installation, disposal and any specialist work where the actual project needs them. If access or a hidden condition changes, document the affected scope and agree a revised price instead of silently extending the base amount.
Before you send the estimate
- Measure each wet wall separately and record niches, corners and tile size so purchasing and installed areas are distinct.
- Keep tile, edge trim and waterproofing products visible as separate selected or provisional items.
- Allow demolition, substrate inspection and curing stages before the screen is refitted.
- Unsound backing discovered after tile removal requires a separate substrate repair decision.
Check business and client details, address, dates, scope, units, line amounts and PDF notes. The shower wall tiling PDF example shows how this fictional project is presented. Its short PDF note is not a substitute for the detailed exclusions above.
