What Drives Bathroom Renovation Costs in Melbourne?
Bathroom renovation costs in Melbourne are driven by a combination of size, materials, labour, and scope of work. Understanding these factors helps you set a realistic budget and make informed decisions about where to invest and where to save.
Bathroom Size
Larger bathrooms cost more — more tiling, more materials, more time. A standard main bathroom (around 5–8m²) costs considerably less than a large ensuite (10–15m²) for the same quality level.
Waterproofing Method
Standard membrane waterproofing is cheaper upfront but more prone to failure. We use the Wedi system — superior, thicker waterproofing backed by a 10-year warranty. Premium waterproofing adds cost but eliminates the most common cause of bathroom failure.
Tile Selection
This is often where costs vary most. Budget porcelain tiles from $30–$60/m². Mid-range rectified porcelain or stone-look $60–$120/m². Imported Italian stone or mosaic $150–$400+/m². Tile selection can swing total cost by $3,000–$15,000.
Fixtures & Fittings
Entry-level tapware, showers and toilets from major chains run $2,000–$5,000. Mid-range fixtures $5,000–$12,000. Premium European tapware, freestanding baths, and frameless screens $12,000–$30,000+.
Vanity & Cabinetry
A flat-pack vanity runs $500–$2,000. A semi-custom unit from a renovator's supplier $2,000–$5,000. A fully custom built-in cabinetry unit with stone benchtop $6,000–$15,000+.
Structural Changes
Moving walls, relocating plumbing, adding skylights, or structural modifications can add $5,000–$25,000+ to a bathroom renovation depending on complexity.
Budget Breakdown: Where Does the Money Go?
For a typical mid-range Melbourne bathroom renovation in 2026 (around $40,000–$55,000), here's a rough breakdown of where the money goes:
What's Changed in Bathroom Renovation Costs Since 2024?
Melbourne bathroom renovation costs have continued to rise into 2026, driven by several factors:
Labour costs
Skilled trades — tilers, plumbers, electricians — continue to command premium rates in Melbourne's tight construction labour market. Expect labour to account for a higher proportion of your renovation cost than 3 years ago.
Material costs
Tile and fixture costs have stabilised after significant increases in 2022–2023, but haven't retreated. Premium European imports remain expensive due to freight costs and currency fluctuations.
NCC & AS3740 waterproofing compliance
Since 2022, all bathroom renovations in Victoria require a full upgrade of waterproofing and substrate materials to comply with the updated National Construction Code (NCC) and AS3740. This is no longer optional — it's a legal requirement that has substantially increased the minimum cost of any compliant bathroom renovation.
Lead times
Some premium fixtures and specialty tiles still have 8–16 week lead times from suppliers. This can affect project timelines and should be accounted for in your planning.
Is It Worth Spending More on a Bathroom Renovation?
For Melbourne homeowners, a well-executed bathroom renovation typically delivers an ROI of 50–80% of the renovation cost in added property value — and significantly more in liveability and daily enjoyment. The key word is "well-executed." A cheap bathroom renovation using substandard waterproofing or inferior fixtures can actually devalue a property when the inevitable failures occur.
The most important investment in any bathroom renovation isn't the tapware or the tiles — it's the waterproofing. A failed waterproofing membrane means water ingress into walls and subfloor, mould, structural timber damage, and a complete redo. This is why Brownlow Building uses the Wedi waterproofing system exclusively — it's more expensive than traditional membranes, but the 10-year warranty protection makes it the only logical choice for a premium renovation.

We provide comprehensive fixed-price quotes that include everything — strip-out, waterproofing, tiling, all plumbing, electrical, vanity installation, accessories, and final clean. No hidden extras, no provisional sums that blow out.
Our quotes include premium waterproofing as standard, fully compliant with the NCC and AS3740. Since 2022, all Victorian bathroom renovations legally require a complete waterproofing and substrate upgrade — this is built into every quote we provide. No surprises, no compliance shortcuts.
Tips for Getting the Best Value from Your Melbourne Bathroom Renovation
Don't move plumbing unless you have to
Relocating plumbing waste points is expensive — typically $1,500–$4,000 per point. Where possible, design your renovation to keep fixtures in their existing locations.
Combine with other renovations
If you're also renovating a kitchen or laundry, doing them simultaneously reduces trade visit costs and overall disruption. Brownlow Building coordinates all trades in-house.
Invest in waterproofing, save on accessories
Splurge on quality waterproofing and tiling (these last decades). You can swap out tapware and accessories later for much less cost.
Get a fixed-price quote — not a provisional sum
Provisional sum quotes leave you exposed to cost blowouts. Always insist on a fixed-price contract from a licensed builder who is confident in their scope of works.
