Bathline Know the band, and the signed-off scope, before you sign.
Sydney bathroom quotes go wrong when one builder leaves out the waterproofing certificate, one carries PC sums for tiles, and one substitutes a cheaper vanity than the one you chose. Here are honest Sydney bands, what moves a renovation inside them, and how every Bathline proposal is itemised line by line so you can compare like for like.
Work out the scope, then ballpark the cost.
A guided tool that steers you between a refresh, an ensuite, a full main bathroom and a strip-back-to-frame rebuild, then gives a realistic band in under a minute. It runs in your browser and stores nothing. It is a guide, not a quote.
Which option do I need?
Five questions, one range. Built on real Sydney bathroom data, not generic builder calculators.
Your estimate appears here.
Step through the questions on the left. As soon as you answer the last one, we point you to the honest scope and a realistic range for a job your size.
Typical Sydney bathroom bands, refresh to strip-back.
| Cheapest in market (Day-rate quote, no fixed price, no name on the waterproofing. Almost always blows the budget.) | $15,000 to $24,000 |
| Refresh, single room (Tiles, vanity and tapware lifted, layout unchanged. Ensuite-only or simple swap-out.) | $22,000 to $38,000 |
| Full renovation, single room (Strip-back-to-frame, new layout, premium selections, fixed-price contract, signed waterproofing.) | $32,000 to $58,000 |
| Whole-home wet areas (Main bathroom + ensuite + laundry, designed and built together on one program.) | $72,000 to $135,000+ |
Six things that decide where your quote lands.
None of them are secrets. Every one is named on your proposal.
Six levers. One honest range.
Layout change
Moving the toilet, shower or vanity adds plumbing rough-in and waterproofing rework. Costs more, but only worth it if the existing layout fights the room.
Selections tier
A budget tile range and a budget tapware range can save 25 to 35 percent over premium European brands, with no compromise on the build itself.
Wet-area size
Two square metres versus six. Each metre of wall tile and each metre of floor tile is labour and material, both linear with size.
Existing condition
Failing waterproofing, water damage to subfloor, or asbestos sheeting all need to be addressed first and add scope.
Access
A third-floor unit with stair-only access, a heritage facade, or a strata building with limited work hours all add days on site.
Specialist trades
Stone-cut vanity tops, custom shower screens or imported feature tiles bring their own lead times and install costs.

Refresh, ensuite, full main bathroom, or strip-back-to-frame?
Ensuite refresh
A tightly-scoped renovation for the ensuite alone, in homes where the main bathroom is already tidy. Three to four weeks on site.
Wrong when: You are planning to redo the main bathroom within twelve months. Better to do both together.
Full bathroom renovation
A complete strip-back-to-frame of the main bathroom, with new layout, waterproofing, fixtures and finishes. Five to seven weeks on site.
Wrong when: A simple cosmetic refresh would do, and the existing layout works for you.
Main bathroom plus ensuite plus laundry
Two or three wet areas renovated together on a single program. Eight to ten weeks on site, one mobilisation, one final clean.
Wrong when: You only want one room done. The savings on shared crew time apply at two or more rooms.
Leak repair and re-waterproofing
Targeted intervention when a bathroom is leaking, the membrane has failed, or there is hidden water damage. Scope is assessed on site.
Wrong when: The bathroom is dated but dry. Plan a full renovation instead.
