You know your bathroom needs work. The cracked tiles, the dripping tap, the vanity that looks like it survived the 90s — but probably shouldn't have. What's stopping most Melbourne homeowners isn't motivation. It's the fear of not knowing what it's all going to cost.
That uncertainty is completely normal. And honestly, it's one of the most common things we hear from homeowners across Melbourne's south-east.
Here's the truth: Bathroom Renovation Cost Melbourne vary a lot. A basic refresh can start around $10,000. A full ensuite overhaul with premium finishes can push past $40,000. The gap is wide — but it's not random. Every dollar in that range comes down to specific, predictable factors.
By the end of this guide, you'll know exactly what drives those costs, what's realistic for your budget, and how to avoid the mistakes that blow out timelines and bank accounts. We've completed bathroom renovations across Dandenong, Cranbourne, Berwick, Narre Warren, and the broader Melbourne south-east — so everything in this guide is grounded in real local experience.
What Is the Average Bathroom Renovation Cost in Melbourne?
According to the Housing Industry Association (HIA), the average bathroom renovation in Australia costs around $26,000. Melbourne tends to sit slightly above that national figure, largely because of higher trade labour rates compared to other Australian cities.
Melbourne bathroom renovations typically cost between $24,000 and $28,000 for standard projects. Budget renovations range from $12,000 to $18,000, while premium renovations exceed $38,000 with structural changes.
That said, "average" is a dangerous word in renovation. Your costs depend on three things above everything else: the size of the bathroom, the quality of fixtures and finishes you choose, and whether you're moving any plumbing around.
Bathroom Renovation Cost by Size
Here's a realistic breakdown based on current Melbourne market rates:
| Bathroom Size | Typical Cost Range | What's Usually Included |
|---|---|---|
| Small (under 5m²) | $10,000 – $16,000 | Retile, new vanity, shower, toilet, waterproofing |
| Medium (5–8m²) | $16,000 – $28,000 | Full remodel, new fittings, updated plumbing |
| Large / Ensuite (8m²+) | $28,000 – $45,000+ | Custom fit-out, premium fixtures, structural changes |
Bathroom Renovation Cost by Finish Level
Your choice of finishes is the second-biggest lever on price — and it's entirely in your hands.
| Finish Level | Estimated Cost | Best For |
|---|---|---|
| Budget | $10,000 – $15,000 | Rental properties, cosmetic upgrades |
| Mid-Range | $15,000 – $28,000 | Family homes, resale value improvement |
| Luxury | $28,000 – $45,000+ | High-end homes, lifestyle-focused renovation |
Most Melbourne homeowners renovating the family bathroom land somewhere in the mid-range. It's the sweet spot where quality, longevity, and value actually align.
What's Included in a Bathroom Renovation Quote
This is where a lot of homeowners get caught out. Two quotes can look similar on the surface and be wildly different underneath. Here's what should be in any professional renovation quote — and what it typically costs.
Labour Costs: The Trades You'll Need
Labour accounts for roughly 35–45% of your total renovation budget. In Melbourne, Melbourne trades charge around $68.80 per hour on average (2025 rates), which is higher than most Australian cities.
A standard bathroom renovation involves at least four licensed trades:
- Licensed plumber — rough-in work, fixture installation, waterproofing inspection. Melbourne plumbing labour typically runs around $100–$150 per hour.
- Tiler — floor and wall tiling, grouting, silicone sealing
- Electrician — exhaust fan, lighting, heated towel rail, safety switches
- Waterproofer — membrane application and compliance certification
In Victoria, all of these trades must be licensed. Any building work over $10,000 must be supervised by a Registered Building Practitioner. Using unlicensed workers — even for small jobs — can render the work non-compliant. That matters when it comes time to sell your home or make an insurance claim.
Materials and Fixtures: Where Costs Quietly Blow Out
Here's a table that surprises a lot of people. The gap between budget and premium fixtures is enormous — and tapware is often where homeowners accidentally overspend.
| Item | Budget | Mid-Range | Premium |
|---|---|---|---|
| Vanity | $300 – $600 | $600 – $1,500 | $1,500 – $4,000+ |
| Shower Screen | $400 – $800 | $800 – $1,800 | $1,800 – $4,000+ |
| Tiles (per m²) | $30 – $60 | $60 – $120 | $120 – $300+ |
| Toilet Suite | $200 – $400 | $400 – $900 | $900 – $2,500+ |
| Tapware Set | $150 – $350 | $350 – $800 | $800 – $3,000+ |
A realistic materials budget for a mid-range renovation sits at around $7,000–$12,000. The labour to install those materials is on top of that.

Hidden Costs That Blow Out Bathroom Renovation Budgets
Nobody likes budget surprises. The good news is most of them are predictable — if you know where to look.
Waterproofing Compliance (AS 3740)
This one is non-negotiable. The minimum requirements for the materials, design, and installation of waterproofing for domestic wet areas are outlined within AS 3740.
In plain terms: every wet area in your bathroom must be properly waterproofed by a licensed contractor, with a compliance certificate issued on completion. Key requirements include waterproofing that extends at least 150mm above shower floors, and the entire shower area — including walls up to 1.8m high — must be waterproofed.
The cost to waterproof a bathroom is between $750 and $1,500. For safety and legal purposes, this amount is non-negotiable.
Skipping proper waterproofing — or using an unlicensed contractor to save money — is one of the most expensive mistakes a Melbourne homeowner can make. Water damage behind tiles can go undetected for years, and the repair bill when it surfaces is always far worse than getting it right the first time.
Structural Surprises in Older Homes
If your home was built before 1990, budget a 10–15% contingency on top of your planned renovation cost. Rotted subfloor, mould behind original tiles, and ageing plumbing are common discoveries once walls come down. They're not always there — but when they are, they need to be fixed before anything else happens.
Moving Plumbing (The Expensive Decision)
Want to relocate the toilet to the other wall? Move the shower to the opposite corner? Relocating a toilet adds $1,500 to $3,000. Shifting a shower or bath costs $2,000 to $4,000.
Keeping your plumbing in the same position as the original layout is one of the most effective ways to control your renovation budget. It doesn't mean you can't change the look dramatically — it just means the pipes stay put.
Council Permits: When Do You Need One?
In Melbourne, a building permit is required if your bathroom renovation involves structural changes, moving plumbing or drainage, altering electrical systems, or modifying waterproofing compliance. Cosmetic updates such as replacing tiles, fixtures, or vanities in the same location typically do not require a permit.
Always confirm with a registered building surveyor before you start work. Permit approval typically adds two to four weeks to the project timeline — factor that into your planning.
How to Budget for a Bathroom Renovation in Melbourne (Step-by-Step)
Here's a practical process that works for any budget level.
Step 1 — Separate Must-Haves from Nice-to-Haves
Write two lists before you talk to a single contractor. List one: the things that genuinely need to be done (broken shower, failing waterproofing, non-functional toilet). List two: the things you'd love to have (heated floor, freestanding bath, frameless screen).
Start with list one. Add from list two based on what the budget allows. This single exercise regularly saves homeowners $3,000–$8,000 by keeping scope in check.
Step 2 — Set Your Budget, Then Add 15%
Here's the rule: whatever number you land on as your target spend, add 15% on top as a contingency. Not because things will definitely go wrong — but because they sometimes do, and surprises are much less stressful when you've already planned for them.
So if your target renovation spend is $20,000, your actual working budget should be $23,000.
Step 3 — Get 3 Itemised Quotes and Compare Them Properly
Always get at least three quotes from licensed contractors. And compare them line by line — not just the totals.
Look for: Is waterproofing explicitly included? Are all trades listed? Is there a warranty on labour and materials? Is the scope of work clearly defined?
Red flags to watch for: vague line items like "bathroom renovation — labour," no mention of waterproofing compliance, no licence number listed on the quote document.
It's easy to find cheap quotes — but beware. If a quote seems too good to be true, it usually is. Cutting corners in waterproofing or structural prep could cost you thousands down the line.
Step 4 — Understand How Payment Is Structured
A standard renovation payment schedule looks like this: a deposit (typically 10% of the total) before work begins, progress payments at agreed milestones during the build, and a final payment on practical completion.
In Victoria, never pay more than a 10% deposit before work starts — this is a consumer protection measure under Victorian building law. And always hold the final payment until any defects are resolved to your satisfaction.
Bathroom Renovation Costs Across Melbourne South-East Suburbs
Costs are broadly consistent across Melbourne's south-east, though inner suburbs closer to the CBD can carry a slight premium due to access, parking, and trade travel time. Here's a realistic guide for key areas we service:

Frequently Asked Questions
Most Melbourne bathroom renovations cost between $15,000 and $28,000 for a standard-sized bathroom with mid-range finishes. The HIA says a bathroom renovation could cost anywhere from $8,000 to $35,000 or more, with the final number depending on size, finish quality, and whether any structural or plumbing changes are involved
Budget renovations typically take 2 to 3 weeks. Mid-range renovations take 3 to 5 weeks. Premium renovations take 5 to 8 weeks. Permits, where required, add 2 to 4 weeks to the overall timeline. Always factor in delivery lead times for tiles and fixtures — these can add a week or more if ordered specially.
Most bathroom renovations in Victoria require a building permit unless exempted. Minor repairs like replacing taps, mirrors, or re-grouting tiles usually don't need one. But once you change structure, layout, or plumbing, you move into permit territory. When in doubt, check with a registered building surveyor before work starts — the Victorian Building Authority (VBA) website is also a reliable reference.
Keep the plumbing where it is (no pipe relocation), choose mid-range tiles over designer stone options, source your own fixtures and have the contractor supply labour only, and avoid scope changes once the work has started. Scope changes mid-renovation are the number-one cause of cost blowouts.
Generally, yes. A well-executed mid-range bathroom renovation adds meaningful appeal at sale and typically returns a strong proportion of the renovation cost in added value. Luxury renovations carry more risk of overcapitalising — particularly in outer suburbs. Don't overcapitalise — check comparable sales in your suburb before deciding on your finish level.
Final Word
Understanding bathroom renovation costs in Melbourne puts you in the driver's seat. You stop reacting to quotes and start evaluating them. You know what's fair, what's suspicious, and what's worth paying more for.
To recap: budget for size, not just looks. Include waterproofing and compliance in your plan from day one. Add a 15% contingency. Get three itemised quotes and compare them properly. And work with licensed tradespeople who can back their work with documentation.
Your bathroom is one of the most-used rooms in your home. Getting the renovation right — the first time — is always worth it.
