Honest price ranges for 2025 — from a cosmetic refresh to a full luxury fit-out. What the numbers actually mean, what drives cost up or down, and what to watch for when getting quotes in Sydney.
A cosmetic refresh — new tiles, tapware, and vanity with no layout changes — costs $15,000–$22,000. A full renovation with waterproofing, layout changes, and a complete fit-out runs $28,000–$50,000. A luxury bathroom with a freestanding bath, stone surfaces, and custom joinery starts at $55,000. These ranges apply across Sydney's North Shore and Northern Beaches — labour costs and tradesperson availability are consistent across both areas.
These ranges reflect real projects completed in Sydney in 2024–2025. They assume a standard bathroom of 4–8 sqm. Larger bathrooms or complex layouts will sit at the upper end of each range.
| Renovation Type | What's Included | Typical Cost Range | Timeline |
|---|---|---|---|
| Cosmetic Refresh | New tiles over existing substrate, tapware replacement, new vanity. No layout changes, no waterproofing. | $15,000 – $22,000 | 3–4 weeks |
| Full Renovation | Full strip-out, new waterproofing to AS 3740, layout changes, new plumbing and electrical, complete tile and fixture fit-out. | $28,000 – $50,000 | 5–7 weeks |
| Luxury / High-Spec | Everything in full renovation plus freestanding bath, stone or natural material surfaces, custom vanity joinery, heated floors, frameless screens. | $55,000+ | 6–10 weeks |
| Ensuite (compact) | Full renovation of a compact ensuite — typically 2–4 sqm. Shower, vanity, toilet. | $18,000 – $32,000 | 3–5 weeks |
Labour typically accounts for 40–50% of a bathroom renovation budget in Sydney. The remainder is split between materials and fixtures. Understanding this split helps you make better decisions about where to invest and where to save.
One area not to cut: waterproofing. It represents a small portion of the total budget but is the most consequential element in the build. A failed waterproof membrane causes damage that costs multiples of the original saving to repair.
Most budget blowouts come from factors that weren't identified before work began. These are the most common cost drivers on Sydney projects — and what to do about each one.
A significant portion of Sydney's North Shore and Northern Beaches housing stock is federation, inter-war, or mid-century construction. Original galvanised steel or copper plumbing that hasn't been replaced often needs attention once walls are opened. A thorough pre-quote assessment — not a 20-minute site visit — is the only way to price this accurately. If a builder hasn't looked at your plumbing condition before quoting, their price is an allowance, not a commitment.
Moving a toilet, shower, or bath to a different position in the room requires new waste and supply lines — significant additional plumbing labour. If the existing layout broadly works, keeping it reduces cost substantially. A design brief that works with the existing plumbing positions is always more cost-efficient than one that doesn't.
Large-format tiles (600×1200mm and above) cost more to install than standard formats — they're heavier, require a flatter substrate, and take longer to lay. Natural stone requires sealing and carries higher material cost. The aesthetic difference can be significant, but so can the price. A good renovator helps you find the right balance for your budget and the property.
Strata buildings in Neutral Bay, Chatswood, and across the North Shore require works approval from the owners corporation before renovation begins. Heritage-listed properties may require council review. Neither of these processes is inherently expensive, but they add time to the pre-construction phase and need to be factored into the project schedule. A builder who doesn't raise this upfront in strata or heritage contexts hasn't done the job properly.
In older bathrooms, the existing waterproof membrane is often degraded or non-compliant. A cosmetic retile over a failed substrate is a short-term fix — the underlying problem will reappear. A proper strip-out that exposes the substrate, and a new waterproof membrane installed to current standards, adds cost but eliminates the most common cause of expensive post-renovation defects.
