A bathroom makeover changes what you can see — tapware, a vanity, paint, lighting, sometimes the grout. A bathroom renovation goes behind the wall: plumbing points, the floor screed, the falls and the waterproof membrane. If the membrane has to come up, you’re renovating, whatever the quote calls it.
That one distinction decides more than the finish. It sets how long you lose the room for, whether a written contract is compulsory, and whether the work falls under Victoria’s domestic building warranty. Most bathroom renovations in Melbourne get compared on budget first. Comparing them on scope gets you a much better answer.
The waterproof membrane decides which job you’re doing
Under the tiles in any Melbourne bathroom there’s a waterproof membrane. Beneath that sits a bed of screed setting the falls toward the waste, plus a set of fixed plumbing points. Those three things are the bathroom. The tiles and tapware are the part you look at.
A makeover works on top of that layer and leaves it alone. A renovation removes it and rebuilds it. Waterproofing of domestic wet areas has a deemed-to-satisfy pathway under AS 3740. Victoria has also been on the 2025 edition of the National Construction Code since 1 May 2026. So once the membrane is disturbed, the work has to meet the current requirement. It is not matched back to whatever was there before.
That’s why the honest question isn’t “how much do I want to spend?” It’s “does anything behind the tiles need to change?”
A makeover changes the surfaces and leaves the substrate alone
A makeover is the right call when the bones are sound and the room just looks tired. Typical scope:
- New tapware, shower rose, towel rails and door furniture
- A new vanity and basin sitting on the existing plumbing points
- New mirror, shaving cabinet and light fittings
- Fresh paint on unlined surfaces and ceilings
- Re-grouting, and replacing perished silicone at the wall and floor junctions
The room usually stays part-usable, and the work runs in days rather than weeks. That’s the real appeal for a household with one bathroom.
What a makeover won’t do is fix a leak or a failing membrane. It won’t correct floor falls that pond water, an extraction fan that can’t clear the steam, or a layout that never worked. Cosmetic work over any of those buys a better-looking version of the same problem.
A renovation starts when the floor comes up
A full renovation strips the room back to the frame and slab. Plumbing points can move, so the shower, bath and vanity can go where you actually want them. The floor is re-screeded to correct falls, a new membrane goes down, and the room is re-tiled over it. Ventilation, lighting and waterproofing all get brought to current requirements at the same time.
It’s more disruptive, and there’s no honest way around that. MBBR’s own timeline guide puts a typical bathroom at 2 to 6 weeks on site and 8 to 16 weeks from first contact to handover. The booking window runs longer again in peak months. If you’re weighing the two options, that gap in disruption matters as much as the gap in scope.
Renovation vs makeover, side by side
| What’s involved | Makeover | Renovation |
| Waterproof membrane | Left intact | Removed and replaced |
| Floor screed and falls | Untouched | Re-laid and re-graded |
| Plumbing points | Stay where they are | Can be moved |
| Tiling | Kept, re-grouted or re-sealed | Stripped and re-tiled |
| Layout | Fixed | Open to change |
| Ventilation | Fan swap at best | Brought to current requirements |
| Room out of action | Days | Weeks |
| Fixes an active leak | No | Yes |
Scope varies job to job. Treat this as the shape of the decision, not a fixed specification.

Three questions that settle it for most homes
Is anything wet, soft or mouldy where it shouldn’t be? Dark grout that won’t clean up. A spongy patch at the shower threshold. Paint lifting on the other side of the wall, or a musty smell that returns after every shower. Those point at the membrane or the falls, and surface work won’t reach either. That’s a renovation.
Does anything need to move? A shower you can’t turn around in, a door that clashes with the vanity, a bath nobody uses. Moving a plumbing point means opening the floor, and opening the floor means a new membrane. That’s a renovation too.
How long can you lose the room? If the answer is a weekend, and the first two answers were no, a makeover is a sensible piece of work rather than a compromise. A Melbourne bathroom can be structurally sound and simply dated.
If two of the three point one way, that’s your answer.
What changes legally once the work gets bigger
Scale changes the rules for Melbourne bathroom renovations, and these thresholds are worth knowing before you sign anything. They’re set in Victorian law and they’re about the value of the work, not about who you hire.
- Above $10,000, you must have a major domestic building contract in writing. Consumer Affairs Victoria sets that threshold, and recommends a written contract below it as well.
- Above $10,000, the work must be done by a registered builder. The Building and Plumbing Commission is the Victorian regulator, and that figure includes labour, materials and GST across the whole project. You can look up any practitioner on the BPC register before you commit.
- Above $20,000, eligible domestic building work is covered by Home Warranty. Home Warranty replaced Domestic Building Insurance on 1 July 2026, for eligible contracts signed on or after that date. The old scheme applied above $16,000, and existing policies continue on their original terms.
None of those numbers is an estimate of what a bathroom costs. They’re the points at which extra consumer protections switch on.
Where cost fits into the decision
We don’t publish a price for either option, and the reason is simple. What a job costs depends on your bathroom’s condition, the access to it, and the requirements specific to that room. Two bathrooms the same size can land a long way apart once the tiles come off.
What’s worth saying is that a makeover isn’t automatically the cheaper path. If the membrane is already failing, cosmetic work gets stripped out again within a few years and you pay for the room twice. Compact rooms also behave differently from how people expect. Small bathrooms can cost more per square metre, because permits, waterproofing and plumbing don’t shrink with the floor area.
Working to a tight number? Start with how to budget a bathroom renovation for under $5,000, then the five things to fix first when costs start spiralling. Both deal with scope before finish, which is the order that keeps a job honest.

Work out the scope before you shop the price. If the membrane, the falls and the plumbing points are sound, a makeover will do the job and you’ll have the room back quickly. If any of the three is in question, a renovation is the cheaper decision in the long run, even though it’s the bigger one today. Walk to your bathroom with the three questions above and write down what you find. You’ll then be able to brief a renovator properly, instead of comparing quotes that cover different work.
