THE SHORT ANSWER
Estimate tap replacement by product selection, existing access and connection readiness. Keep the fixture allowance, removal and connection parts separate so the customer can see the assumptions behind a small plumbing job.
This Australian walkthrough uses a fictional one existing-sink tap change in Gold Coast, Queensland. The matching kitchen tap replacement estimate example shows the same item quantities and amounts in an app-exported PDF. Measure your own site and replace the example rates before issuing a client quote.
1. Record the fixture and sink
Confirm mounting-hole configuration, clearances and selected tap before pricing a final installation. Product fit is more useful than a generic tap count.
For this example, the agreed starting scope is: Replace one kitchen tap at an existing suitable sink and water-supply arrangement. Include owner-selected tap allowance, removal, connection parts allowance, installation, visible leak check and cleanup. No sink replacement or supply-line relocation. A change to a listed surface, product or access assumption should trigger a revised line or allowance.
2. Inspect access under the sink
Crowded cabinets, damaged shutoffs or corroded connections may change the work. The example assumes usable existing connections and treats repairs as a scope change.
3. Identify material responsibility
State whether the contractor buys the tap and which small connection parts are allowed. If the owner supplies it, remove or adjust only the material allowance.
4. Finish with a defined check
List a visible connection and operation check plus cleanup. Do not roll a broader plumbing-system diagnosis into a tap swap without a separate description.
Worked kitchen tap replacement calculation
Two checkable lines from the example are 1 job × A$91.00 = A$91.00; 1 each × A$126.00 = A$126.00. The full 7-line estimate totals A$1,155.00 with the demonstration tax input at 0%. The amount is a fictional scenario, not an Australian market rate or a recommended selling price.
Material purchasing and installed quantities may differ. For your own estimate, use the actual takeoff, supplier prices, labour plan, access and disposal requirements. Decide how overhead, profit and the applicable tax treatment affect your final quote; do not copy the example's zero tax setting.
Before you share the estimate
- Confirm mounting compatibility.
- Inspect access and existing shutoffs.
- Identify tap supplier.
- State leak-check and repair boundaries.
Scope boundary in this example: No sink replacement, shutoff repair, supply relocation, drain alteration or concealed water-damage repair.
Confirm the client details and location, item descriptions, measured units, total and validity date. If opening up the work reveals a different condition, document the changed scope and price before proceeding.
Common questions about kitchen tap replacement
Can I quote a tap without a model?
Use a labelled product allowance for an early estimate, then verify the selected model against the sink before finalizing the scope.
Are new shutoffs included?
Only if listed. This example assumes the existing shutoffs are suitable and prices any repair separately.
