Full Bathroom Renovation Cost Melbourne 2026: Real Price Guide

If you've been quoted anywhere between $9,000 and $40,000 for the same job, you're not being scammed. You're just looking at three completely different renovations that all get called "bathroom renovation Melbourne" by different tradies. The bathroom renovation cost in Melbourne depends far more on scope than most homeowners expect, and once you know which category your project actually sits in, the quotes start making a lot more sense.

We've covered small bathroom renovation budgets before. This time we're talking about the full-size family bathroom or main bathroom job, the one where you're not squeezing a shower into a 2 square metre nook but actually reworking a proper room, often with a bath, separate shower and a decent run of vanity.

Bathroom Renovation Cost Melbourne: The Three Real Tiers

Melbourne renovators generally group bathroom jobs into three tiers, and knowing which one you're aiming for before you start calling around saves everyone time.

Basic renovation: roughly $8,000 to $12,000. This keeps your existing layout, swaps in a new vanity, toilet and tapware, and uses budget-friendly tiles. Good for a tired bathroom that isn't leaking or falling apart, just dated. Homeowners looking to refresh cosmetics often look at smart bathroom updates to keep expenses lean.

Mid-range renovation: roughly $12,000 to $25,000. This is where most Melbourne homeowners actually land. Think a semi-custom vanity, floor-to-ceiling tiling instead of tiles to dado height, and quality (not premium) fixtures. It's the sweet spot between "looks new" and "financially sensible." Explore our dedicated complete bathroom renovations guide for what is typically included in this tier.

Luxury renovation: $25,000 upward, often into the $40,000s. Custom cabinetry, designer tapware and tiles, walk-in showers, freestanding baths, and usually a layout change, which brings its own costs we'll get to shortly.

Two real examples give you a feel for how this plays out on the ground. A compact 2m by 2m apartment bathroom in Bentleigh came in around $9,800, a straightforward basic-to-mid job. A larger family bathroom renovation in Bayside Brighton, with more floor area and a bath-plus-shower layout, landed closer to $18,500. Same city, same general market, very different scope.

Where the Money Actually Goes

On a typical Melbourne bathroom job, labour and trades eat up 45 to 55 percent of the budget. Materials and fittings, your tiles, vanity, tapware and the rest, account for another 35 to 45 percent. The remaining 10 to 15 percent covers design, compliance and a contingency buffer that you genuinely should not skip, because bathrooms are the room most likely to reveal a surprise once the old tiles come off.

If you want a sense of trade rates driving that labour percentage, Melbourne plumbers are currently charging somewhere between $100 and $150 an hour, electricians sit around $90 to $130, and professional tilers are typically $60 to $100 an hour. A full bathroom strip-out and rebuild involves all three trades plus a waterproofer, which is exactly why labour dominates the budget rather than materials.

Ensuite Renovation Cost in Melbourne: Why It's Rarely Cheaper

A lot of homeowners assume an ensuite renovation in Melbourne should sit below a main bathroom because the footprint is smaller. In practice it often lands in the same mid-range bracket, because you're still paying for a full waterproofing job, a shower base or hob, and usually a vanity, regardless of whether the room is 3 square metres or 6. The fixed costs of getting trades on site and doing the wet-area work properly don't shrink much just because the tile count does.

Where ensuites genuinely save money is when you keep the existing layout and plumbing points untouched. Move a toilet or a shower drain even 500mm and you're into new drainage penetrations, which changes the whole cost and compliance picture.

The Permit Question Nobody Explains Properly

This is the part that catches a lot of Melbourne homeowners out. Plenty of renovations genuinely don't need a building permit. If you're doing cosmetic work only, replacing the vanity, toilet, tapware and tiles in their existing positions without touching the waterproofing membrane, you can usually get away without one.

But a building permit is required in Victoria once your renovation involves any of the following: structural walls or floor framing, replacement of the waterproofing membrane, relocation of the toilet, shower or floor waste, new drainage penetrations, or any change to the bathroom's footprint. Most full bathroom renovations, by their nature, tick at least one of these boxes, because ripping out old tiles almost always means redoing the waterproofing underneath.

That last point matters more than most quotes make clear. Old waterproofing membranes in Melbourne homes, particularly anything renovated before the mid-2000s, are frequently well past their usable life and won't meet current standards once inspected. If your renovator's quote doesn't explicitly mention waterproofing certification and, where relevant, a building permit, ask why. It's not a box-ticking exercise. It's the difference between a bathroom that's protected against water damage for the next fifteen years and one that starts showing damp patches in the bedroom next door within eighteen months.

Questions Worth Asking Before You Sign Anything

A few direct questions separate a good quote from a vague one. Ask whether the price includes a building permit if one is required, not as a variation later. Ask whether waterproofing is being replaced or just patched over the existing membrane. Ask for a written allowance for plumbing relocation if you're changing the layout at all, since this is the single biggest source of "unexpected" cost blowouts. And ask what happens if they find rot or subfloor damage once the old tiles come up, because in older Melbourne weatherboard and brick veneer homes in areas like Camberwell or Brunswick, this happens more often than renovators like to admit upfront.

Getting a Realistic Bathroom Renovation Melbourne Quote

If you're comparing quotes and one comes in dramatically below the others, it's worth asking exactly what's included before getting excited. A genuinely competitive mid-range quote for a full bathroom in Melbourne in 2026 should sit somewhere in that $12,000 to $25,000 band once you account for a proper vanity, full-height tiling, new waterproofing and standard fixtures. Anything well under that either assumes you're keeping more of the existing layout than you think, or it's missing a line item that will reappear later as a variation.

The most useful thing you can do before your first quote appointment is decide, honestly, which of the three tiers you're actually renovating for. A basic refresh, a solid mid-range family bathroom, or a genuine luxury rebuild. Walking in with that clarity means every quote you receive gets measured against the same yardstick, rather than three unrelated numbers that all sound like they should be comparable.
