Ask the contractor for the programme that applies to your room.
Questions to take to the renovator
- Can the proposed scope be delivered within an itemised quote?
- Which preparation items remain provisional until the room is opened?
- What product models are included in the fixture allowance?
- How will building access or approval costs affect the total?
Make the written quote comparable
Ask whether GST, delivery, demolition, disposal, protection, making good and provisional sums are included.
Confirm who supplies fixtures and how changes are approved and priced.
For an apartment, include building access, common-area protection and the strata approval process in the brief.
Read the NSW strata renovation guidance with your strata manager.

Budget questions
What does this $20,000 budget represent?
This $20,000 example explores a compact renovation that retains the existing fixture layout and uses stock products.
The model includes preparation, wet-area work, tiling and fixtures, with a contingency inside the total.
A site inspection may identify a different scope or price, so ask the contractor to test these assumptions before selecting products.
Is this a quote for my bathroom?
This is an illustrative budget exercise. A contractor needs to assess your property, scope, access and selections before quoting.
How should I allow for timing?
Ask the renovator for a project-specific schedule that includes ordering, approvals, trade sequencing and curing requirements.
