If you’ve started Googling “bathroom renovation cost Melbourne” at midnight, you already know the frustration. One site says $15,000. Another says $50,000. Neither one tells you why.

Here’s the direct answer: a bathroom renovation in Melbourne typically costs between $15,000 and $80,000 in 2026, depending on size, layout changes, and finish quality. Most homeowners land in the $22,000 to $35,000 range for a quality mid-range result. The Housing Industry Association cites a national average of $26,000, though Melbourne pricing shifts based on trade demand and local logistics. 

We’ve been renovating bathrooms across Melbourne for 15 years at JBK Homes, and the truth is this: the number matters less than understanding what’s driving it. Once you know that, you can spend your budget where it counts and skip the parts that don’t.

How Much Does a Bathroom Renovation Cost in Melbourne?

Your bathroom’s final price tag comes down to one thing more than any other: finish quality. Here’s how the three main tiers typically break down.

TierCost RangeWhat’s IncludedTimeline
Basic$15,000–$22,000New tiles, standard vanity and toilet, existing layout kept2–3 weeks
Mid-Range$22,000–$35,000Better fixtures, some layout changes, quality tiles3–4 weeks
Luxury$35,000–$80,000+Custom joinery, freestanding bath, full layout changes4–6 weeks

Labour typically accounts for 40% to 50% of your total budget, so a bathroom renovation isn’t just about picking pretty tiles. It’s about paying skilled trades to get the unglamorous parts right: waterproofing, plumbing, and electrical work that you’ll never see once the tiles go on, but will absolutely notice if it fails. 

That table shows quality tiers. Size affects your budget too, and it deserves its own explanation.

Bathroom Renovation Cost by Size

Size and quality aren’t the same thing. A tiny ensuite can still get a luxury finish, and a large family bathroom can be renovated on a modest budget. Here’s how bathroom size typically shifts your costs.

Small Bathroom and Ensuite Renovation Cost

Small bathrooms and ensuites usually cost $15,000 to $25,000 to renovate fully. That might surprise you, given how little floor space is involved. The catch is that your plumber, electrician, and waterproofer still need to complete the same technical steps as they would in a bigger room. Less space rarely means proportionally less labour.

Where you do save is on materials. Fewer tiles, a smaller vanity, and less waterproofing membrane can shave a few thousand dollars off a comparable mid-size job.

Mid-Size Bathroom Renovation Cost

A standard Melbourne family bathroom, somewhere around 5 to 8 square metres, typically costs $22,000 to $35,000 for a quality renovation. This is where most homeowners land, and it’s the size where layout changes start making financial sense. Moving a toilet or shower a metre or two adds cost, but it can also solve years of frustration with an awkward floor plan.

Large and Luxury Bathroom Renovation Cost

Bathrooms over 10 square metres, or projects with a genuine luxury brief, generally start at $35,000 and can exceed $80,000. This tier is where freestanding baths, frameless glass, heated floors, and custom stone benchtops come into play. Labour costs climb here too, since bigger spaces mean more tiling hours and longer installation timelines.

What Affects Your Bathroom Renovation Cost?

Beyond size and quality tier, a few specific decisions move the needle more than anything else.

Layout Changes and Plumbing Relocation

Keeping your toilet, shower, and vanity in their existing spots is the single biggest cost saver available to you. Relocating plumbing fixtures typically adds $1,500 to $3,000 per fixture, since it means opening walls or floors and re-routing pipework that was never designed to move.

Fixture and Finish Quality

Standard ceramic tiles cost $40 to $60 per square metre, while natural stone can reach $150 or more. Vanities range from $1,200 for laminate options to $4,500 for custom stone-top builds. None of these choices is wrong; they’re just different budgets for different priorities.

Electrical Upgrades

Heated flooring and smart lighting controls are increasingly popular in Melbourne bathrooms, but they add $3,000 to $5,000 to your electrical scope. Worth it for daily comfort, but good to budget for upfront rather than discover mid-project.

Access and Location

Upper-level bathrooms cost more to renovate than ground-floor ones, since plumbers need to work around existing floor and ceiling cavities. Heritage-overlay suburbs like Fitzroy, Brunswick, and Camberwell can also add time and cost, as period homes often hide surprises behind original walls.

Cost Breakdown by Bathroom Element

If you want to know exactly where your money goes, here’s the typical split.

Tiling and waterproofing usually represent 25% to 35% of your total budget. Waterproofing under current Australian standards requires a full-floor membrane, wall upturns, and a licensed waterproofing certificate before tiling begins, typically costing $1,500 to $5,000. This isn’t an area to cut corners; poor waterproofing is one of the most expensive mistakes to fix later.

Vanities and storage range from $1,200 for a basic laminate unit to $4,500 for a custom stone-top build with soft-close drawers.

Showers, baths and tapware vary enormously. A standard shower screen might cost $600, while a frameless system reaches $2,500. Freestanding baths start around $1,500 and climb well beyond $6,000 for premium models.

Labour versus materials typically splits close to 50/50, with the remaining 10% to 20% covering permits, disposal, and contingency.

Hidden Costs Homeowners Often Miss

A few expenses catch Melbourne homeowners off guard, mostly because they’re invisible until demolition starts.

Asbestos testing and removal. If your home was built before 1990, budget for testing before any wall or floor is touched. Removal costs vary depending on scope, but skipping this step isn’t legal or safe.

Permit and council fees. Bathroom renovations involving structural changes, plumbing alterations, or waterproofing require permits, with total costs typically ranging from $1,200 to $2,000 once building, plumbing, and electrical certification are included.

Structural surprises. Older Melbourne homes sometimes hide rotting floor joists or outdated plumbing stacks behind existing tiles. A contingency of 15% to 20% covers these without derailing your project.

Waterproofing compliance certificates. These are a legal requirement, not an optional extra, and they protect you if you ever sell the property.

How to Get the Best Value for Your Bathroom Renovation

You don’t need every finish to be premium to get a bathroom that feels premium. Mid-range vanities with quality hardware often look nearly identical to custom stone builds at a fraction of the price. Keeping your existing plumbing layout, where it already works well, frees up budget for better tiles or tapware instead.

If your budget is tight, ask your builder which trades can be staged. Fixed-price contracts also protect you from the blowouts that come with vague, itemised quotes.

Frequently Asked Questions

Does a bathroom renovation actually add value to my home?
Yes, and it’s one of the better returns you’ll get from any renovation. A well-executed bathroom typically recovers a strong share of its cost at resale, sometimes more if your current bathroom is genuinely dated. The catch is that over-spending on luxury finishes in a modest home won’t add proportional value. Match your renovation to your suburb and your home’s overall standard, and the return takes care of itself.

Can I still live in my house while my bathroom is being renovated?
In most homes, yes, especially if you have a second bathroom or ensuite to fall back on. If your bathroom being renovated is your only one, plan for a few weeks of showering elsewhere or setting up a temporary arrangement. A good builder will give you a realistic timeline upfront so you’re not caught off guard halfway through.

How many quotes should I actually get before choosing a builder?
Three is the sweet spot. Fewer, and you don’t have enough to compare properly. More, and you’re often just seeing minor variations on the same numbers. When you compare quotes, look past the total figure and check whether each one includes the same scope, permits, and waterproofing certification. Two quotes can look completely different in price simply because one of them is quietly leaving something out.
