Bathroom renovation FAQs

How long does a bathroom renovation take?
Our bathroom renovations take around 4 weeks from demolition to handover. You'll receive a fixed schedule before we start, and your project manager updates you at every stage.
How much does a bathroom renovation cost in Sydney?
Most complete bathroom renovations in Sydney cost between $20,000 and $35,000, depending on size, finishes and whether plumbing moves. We provide a free, fixed-price quote after an in-home measure.
Do I need council approval to renovate my bathroom?
Usually not. If your renovation keeps the same footprint, standard bathroom renovations in NSW don't require a development application. If structural changes are involved, we manage any approvals for you.
Can you renovate bathrooms in apartments?
Yes. We regularly renovate strata apartments across Sydney and handle by-law requirements, work-hour restrictions and the waterproofing documentation your strata committee needs.
What waterproofing standard do you follow?
All waterproofing complies with Australian Standard AS 3740 and is applied by licensed waterproofers using our advanced membrane formula. You receive a compliance certificate, and it's covered by our 10-year warranty.
Is my quote fixed, or can the price change?
Your quote is fixed for the agreed scope. The only variations are ones you request, or unforeseeable structural issues discovered after demolition — which we document and price before any extra work proceeds.
