The average bathroom renovation cost in Australia sits between $12,000 and $35,000 for most households in 2026. But "average" hides a wide spread — a cosmetic refresh is possible for $5,000, while a full wet area rebuild with custom tiling can exceed $50,000.
Average bathroom renovation cost by scope
The single biggest cost driver in a bathroom renovation is whether you're keeping or moving the wet areas — shower, bath, and toilet. Moving plumbing even 300mm adds $2,000–$5,000 to any quote.
| Scope | Cost Range | What's included |
|---|---|---|
| Cosmetic refresh | $5,000–$10,000 | Repaint, new vanity, toilet suite, taps. Keep existing layout. |
| Budget renovation | $12,000–$20,000 | New tiles, shower, vanity, toilet. No layout changes. |
| Mid-range renovation | $20,000–$35,000 | Full gut, quality tiles, frameless shower screen, freestanding bath option. |
| Premium renovation | $35,000–$60,000 | Custom tiling, heated floors, large format tiles, high-end fixtures. |
| Luxury / ensuite + main | $60,000+ | Complete master ensuite + main bathroom, custom joinery, premium fittings. |

The hidden costs that blow out bathroom renovation budgets
Waterproofing failures are the most expensive bathroom renovation surprise. When tiles come off, failed or missing waterproofing underneath means rectification work before anything new can go on. Add $1,500–$4,000 if your existing bathroom has no waterproofing membrane — common in homes built before 1996.
Other frequent surprises: asbestos in wall sheeting or floor tiles ($1,500–$4,000 to remove), damaged subfloor joists from years of moisture ($800–$3,000), and the cost of living without a bathroom during the 2–4 week renovation.
How to get the best bathroom renovation price
Get three itemised quotes — not lump sums. An itemised quote lets you compare like-for-like and spot where one tradie is cutting corners. Specify your tile selection before quoting (tile costs vary enormously — $20/sqm vs $120/sqm makes a $3,000 difference on a standard bathroom). Lock in your product selections before work starts — mid-renovation changes are the fastest way to add 20% to your bill.
What is the average cost to renovate a bathroom in Australia?
The average bathroom renovation in Australia costs $20,000–$35,000 for a mid-range project in 2026. Budget renovations start from $12,000 for a straightforward tile-and-fit job with no plumbing moves. Premium renovations with custom tiling and high-end fixtures run $35,000–$60,000+.
How long does a bathroom renovation take?
Most bathroom renovations take 2–4 weeks from demolition to completion. Complex renovations with custom tiling, floor heating, or structural changes can take 5–7 weeks. The critical path is usually waterproofing cure time (24–48 hours) and tiling, which can't be rushed.
Can I renovate a bathroom for $10,000?
Yes, but only for a cosmetic refresh — new vanity, toilet, taps, mirror, and a repaint without replacing tiles or moving plumbing. A full renovation (new tiles, shower screen, waterproofing) for $10,000 means compromising heavily on materials or doing significant DIY. Licensed plumbers and tilers are still required for waterproofed areas.
Does a bathroom renovation add value?
A well-executed mid-range bathroom renovation typically returns $1.20–$1.80 for every $1 spent in property value uplift, according to HIA data. The return is higher in entry-level suburbs where a modern bathroom differentiates significantly from unrenovated stock. In premium suburbs, buyers often plan their own renovation so the return is lower.
What is the most expensive part of a bathroom renovation in Australia?
Waterproofing, tiling, and the wet area trade work (plumbing + tiling) are typically the most expensive components — often 40–60% of the total budget. Fixtures and fittings are the easiest place to save without compromising quality.
How long does a bathroom renovation take in Australia?
A standard bathroom renovation in Australia takes 2–4 weeks from demolition to completion. Complex renovations involving layout changes, structural work, or custom fixtures can take 6–8 weeks. Always factor in lead times for tiles, fixtures, and trades.
