Quick Answer
A bathroom renovation in Victoria costs $8,000–$35,000+ depending on size, fixtures, and whether you’re doing a cosmetic refresh or a full gut-and-rebuild. Most Melbourne homeowners spend $15,000–$22,000 for a standard full renovation. Budget an extra 15–20% for older homes in suburbs like Dandenong, Berwick, and Frankston where waterproofing and tiling surprises are common.
What Does a Bathroom Renovation Cost in Victoria?
Bathroom renovations in Melbourne and regional Victoria vary enormously — from a $3,000 cosmetic facelift to a $50,000+ luxury ensuite. The biggest cost drivers are tile selection, fixture quality, waterproofing scope, and whether you need to move any plumbing or electrical points.
Tradesperson rates across southeast Melbourne (Dandenong, Narre Warren, Pakenham, Berwick, Cranbourne, Officer) are broadly similar to metro rates, though some specialist tilers and waterproofers are in high demand during the renovation season from September to April.

What Affects Bathroom Renovation Costs?
1. Size of the Bathroom
A standard bathroom in a 1970s–1990s Melbourne home is typically 3–4 m². Ensuites in newer homes (Cranbourne, Officer, Pakenham) can be 6–10 m². Every square metre of tiling and waterproofing adds cost — expect to add $800–$1,500 per square metre for quality finishes.
2. Moving Plumbing Points
If you want to move the toilet, shower, or vanity to a different position, a licensed plumber must relocate the waste and supply lines. This can add $1,500–$4,500 to your budget and sometimes requires council notification for significant drainage changes.
3. Waterproofing Requirements
Victoria follows AS 3740 (Waterproofing of Domestic Wet Areas). Waterproofing must be done by a licensed waterproofer and inspected before tiling. Skimping here causes expensive problems: water damage, mould, and structural rot. Budget $600–$1,500 and don’t try to DIY this step.
4. Tile Choice and Format
Standard 300x300mm tiles from your local hardware store start at $20–$40/m². Large-format 800x800mm rectified tiles from specialist suppliers cost $60–$150/m² and take longer to lay. The tile choice alone can swing the renovation by $2,000–$6,000.
5. Age of the Home
Homes built before 1990 in suburbs like Dandenong, Frankston, Berwick, and Mornington often reveal surprises: rotted substrate behind tiles, asbestos sheeting (requires licensed removal), and undersized waste pipes. Add 15–20% contingency for any pre-1990 home.
DIY vs Professional Bathroom Renovation
Most bathroom work in Victoria is not legal for homeowners to DIY. This table summarises what you can and can’t do yourself:
| Task | DIY Allowed? | Notes |
|---|---|---|
| Painting walls and ceiling | Yes | Use waterproof bathroom paint |
| Replacing tapware (like-for-like) | Yes (with caution) | Must not modify supply lines; use licensed plumber if in doubt |
| Tiling (walls and floor) | Yes (owner-occupier) | Can tile own home; waterproofing must still be licensed |
| Waterproofing | No | Must be licensed waterproofer in Victoria (AS 3740) |
| All plumbing (pipes, waste, supply) | No | Licensed plumber required; VBA registration mandatory |
| All electrical work | No | Licensed electrician required for all circuits |
| Vanity installation (cabinet only) | Yes | Plumbing connections must be licensed |
Signs Your Bathroom Needs More Than a Refresh
| Problem | Symptom | Action |
|---|---|---|
| Failed waterproofing | Damp smell, stained walls adjacent to shower, soft floor near drain | Full retile required; waterproofing must be redone |
| Asbestos sheeting | Home built pre-1987; fibrous sheeting behind tiles | Licensed asbestos removalist required; budget $1,500–$4,000 |
| Cracked or loose tiles | Tiles hollow when tapped; grout crumbling | Check for water ingress; may need full retile |
| Persistent mould | Black mould on grout, caulk, ceiling; returns within weeks | Likely inadequate ventilation or waterproofing failure |
| Old galvanised pipes | Brown/rusty water initially; reduced pressure | Replumb with copper or PEX while renovation open |
When to Call a Licensed Professional
In Victoria, the Victorian Building Authority (VBA) regulates all domestic building work. Any renovation exceeding $10,000 in value requires a building permit if structural changes are involved. Your plumber must be registered with the VBA and your electrician licensed through Energy Safe Victoria.
Use the VBA’s Find a Practitioner tool to check any tradesperson before engaging them. In southeast Melbourne, also check hipages.com.au and ServiceSeeking for local reviews.
Top 10 Tips and Gotchas
- Get three quotes. Bathroom renovation prices vary 30–50% between contractors in Melbourne. Always compare like-for-like scopes.
- Fix waterproofing first, finishes second. The most expensive mistake homeowners make is prioritising looks over structure. Waterproofing failure causes $10,000+ remediation bills.
- Budget 20% contingency. Tiles crack in transit, substrates are rotten, pipes are in the wrong place. Set aside $2,000–$4,000 before you start.
- Choose tiles before accepting quotes. The tile cost is included in most quotes — if you change to a more expensive tile after signing, expect a variation charge.
- Ventilation is non-negotiable. Melbourne winters create condensation that destroys bathrooms. Install at minimum a 150mm exhaust fan vented to outside (not just the roof cavity).
- Check the exhaust fan rating. Use the Sone rating (quieter = better) and check the L/s air movement. An underpowered fan in a windowless bathroom causes mould within months.
- Niche vs shelf debate. Tiled shower niches look great but add $200–$400 each and require careful waterproofing. Glass shelves are cheaper and easier.
- Heated floor timing. Electric in-slab heating (Heatpax, Devex) must go in before tiles. Retrofitting costs $1,500+. Decide at the start, not during tiling.
- Grout colour matters long-term. White grout shows staining within 12 months in Melbourne hard-water areas. Mid-grey or charcoal grout is far more practical.
- Factor in drying time. Waterproofing needs 48–72 hours to cure before tiling. Rushing this step voids warranties and creates failure points.

Frequently Asked Questions
How long does a bathroom renovation take in Melbourne?
A standard full renovation (strip, waterproof, tile, fit fixtures) takes 10–14 working days. Add 2–3 days if you’re moving plumbing points, or up to 3 weeks if custom joinery is involved. Most trades in SE Melbourne book 2–4 weeks ahead, so planning 6–8 weeks before your desired start date is realistic.
Do I need a building permit for a bathroom renovation in Victoria?
You generally do not need a building permit for a like-for-like bathroom renovation (same layout, no structural changes). However, if you’re moving walls, relocating plumbing drainage, or the project value exceeds $10,000 with structural elements, a permit is required. Check with your local council (Casey, Frankston, Mornington Peninsula, Cardinia, Greater Dandenong) or the VBA.
Can I use cheap tiles from an online store for my Melbourne renovation?
Yes, but order 10–15% extra for cuts and breakage, and confirm delivery lead times — some online tile suppliers have 3–6 week lead times from overseas warehouses. Also verify the tiles meet AS 4663 slip resistance for wet areas (Rating R10 or P3 minimum for bathroom floors).
What’s the cheapest way to update a bathroom without full renovation?
Repainting (including tiles with tile-specific primer), replacing tapware, installing a new vanity mirror, and reglazing the bathtub can transform a bathroom for $1,500–$4,000. Bathtub and tile reglazing by a specialist costs $400–$900 and can extend life by 5–8 years — popular in rental properties across Dandenong and Pakenham.
Is asbestos a concern in Melbourne bathroom renovations?
Yes — homes built before 1987 in suburbs like Frankston, Dandenong, Berwick, and Mornington commonly have asbestos cement sheeting behind tiles or as vinyl floor backing. Any renovation in these homes should start with an asbestos survey ($300–$500). Licensed asbestos removal costs $1,500–$4,000 for a bathroom but is legally required and protects your health and future buyers.
How do I find a reliable bathroom renovator in SE Melbourne?
Check VBA registration for any builder or waterproofer, ask for recent references from completed Melbourne jobs, and get three itemised quotes. Local Facebook groups for Berwick, Narre Warren, and Pakenham residents often have reliable tradie recommendations. Avoid any operator who won’t provide a written quote or insists on a large upfront cash payment.
Final Thoughts
Bathroom renovations in Victoria offer excellent return on investment — a quality renovation in SE Melbourne typically adds $1.50–$2 in property value for every $1 spent. The key is to spend money where it counts: waterproofing, ventilation, and quality tapware last decades; trendy features don’t.
For most Melbourne owner-occupiers, the $15,000–$22,000 mid-range renovation hits the sweet spot — durable, good-looking, and cost-effective. Save the premium budget for master ensuites where buyers make their decision.
- Always verify waterproofer and plumber VBA registration before signing
- Get three itemised quotes; avoid lump-sum-only quotes
- Budget 15–20% contingency for pre-1990 homes
- Don’t compromise on waterproofing — it’s the most important step
- Choose practical grout colours and ventilation over purely aesthetic decisions
