How Much Does a Bathroom Renovation Cost in Melbourne?

If you're planning a bathroom renovation in Melbourne, the first question on your mind is probably: how much is this going to cost me?

Here's the direct answer.

A bathroom renovation in Melbourne typically costs between $10,000 and $35,000+, depending on size, materials, and scope of work. A basic cosmetic refresh starts around $10,000–$15,000. A full mid-range renovation runs $15,000–$25,000. A premium ensuite or high-end transformation can push past $35,000.

Those are the numbers. Now let's talk about what actually drives them — because the difference between a $12,000 bathroom and a $28,000 one isn't always obvious until you're three weeks into a strip-out.

What Affects the Cost of a Bathroom Renovation in Melbourne?

Before quoting any number, a good builder looks at several things. Each one moves the price up or down.

Bathroom size is the starting point. An ensuite is smaller than a main family bathroom, so labour and materials cost less. Simple enough.

Scope of work matters more than size. Are you swapping out the vanity and repainting? Or are you gutting the whole room down to the studs? A cosmetic refresh and a full rebuild are worlds apart in price.

Layout changes are where budgets quietly blow out. Moving the toilet, shower, or vanity means relocating plumbing. That adds $2,000–$6,000 easily. If your budget is under $20,000, keep everything in its current position.

Material grade makes a real difference. Builder-grade tiles and tapware cost far less than imported Italian stone and designer fixtures. Both can look good. One just costs three times more.

Older Melbourne homes add a layer of complexity. Properties built before 1987 may contain asbestos in wall sheeting, flooring, or ceilings. Licensed asbestos removal is legally required, and it's not cheap. Budget $1,000–$3,500+ if your home falls in that era.

In Victoria, waterproofing, plumbing, and electrical work must all be done by licensed tradies. That's not optional. It's the law — and it protects you.

Bathroom Renovation Cost Breakdown by Scope

Here's a practical view of what each tier looks like:

Melbourne labour rates run around 10–15% higher than those in regional Victoria. Tradies in the metro area are in high demand, and that's reflected in pricing. All quotes should include GST — if they don't, ask why.

Where Your Money Actually Goes

This is what a typical mid-range Melbourne bathroom renovation looks like when you break it down:

• Waterproofing: $600–$1,200. This is non-negotiable under Australian Standard AS 3740. Any licensed builder will include it.

• Tiling (floor and walls): $60–$120 per m² for supply and installation.

• Vanity and tapware: $800–$4,000+, depending on brand and style.

• Shower screen: $700–$2,000.

• Toilet suite: $400–$1,500.

• Lighting and exhaust fan: $300–$800.

• Licensed plumber and electrician: $1,500–$4,000 combined.

• Builder or project management fee: Typically 10–20% of the total project cost.

Add those up, and a $20,000 bathroom starts to make a lot of sense. Nothing in that list is padding — it's just what a compliant, quality renovation requires in Victoria.

Hidden Costs Melbourne Homeowners Often Miss

The quote looks fine. Then the walls come down. This is the part no one loves talking about — but you need to know.

Subfloor and wall damage is common, especially in older homes where water has been quietly doing damage for years. Once the tiles come off, you might find rotted timber or mouldy wall cavities. Repairs can add $500–$2,500 to the job.

Asbestos removal, as mentioned, catches many homeowners off guard. If your pre-1987 home hasn't been tested, budget for it before the renovation starts.

Permit fees apply when you're making structural or drainage changes. These vary by council — worth checking early.

Skip bin hire for waste removal runs $300–$600. Some builders include this; many don't. Ask upfront.

Temporary bathroom arrangements are easy to overlook if it's your only bathroom. A few nights in a hotel or staying with family adds real cost to the project timeline.

How to Get an Accurate Quote and What to Ask

Getting three written quotes is standard advice — and it's good advice. But knowing what to look for in those quotes matters more.

Ask each builder to provide an itemised scope of work. A one-line quote that says "bathroom renovation — $18,000" tells you almost nothing. You want to see each trade, each fixture category, and each cost line clearly listed.

Check that your builder holds a valid Victorian Domestic Builder licence. You can verify this directly on the Victorian Building Authority (VBA) register. This takes two minutes and can save you enormous headaches.

Ask whether waterproofing certification is included. In Victoria, this compliance document is required for the work to be considered legally complete.

Under the Domestic Building Contracts Act of Victoria, builders cannot ask for more than 10% deposit on projects under $20,000. Know your rights before you sign anything.

Finally, ask to see photos of previous Melbourne bathroom renovations. Not stock images — actual project photos. A builder with 10–15 years of local experience will have plenty to show.
