Picture your bathroom looking fresh, airy, and chic. You don't have to spend thousands on a complete bathroom renovation to make that dream happen. With the correct planning, a cheap bathroom renovation can look every bit as sophisticated as a full fit-out.

What Does a Cheap Bathroom Renovation Actually Cost in Australia?

When planning a budget-friendly bathroom renovation, having some guide prices is helpful. According to the HIA Bathroom Renovation Cost Guide 2025, a small ensuite bathroom renovation is $10,000 to $25,000 plus in Australia. However, the bathroom renovation cost depends on your state or territory. Generally, costs are higher in Sydney and Melbourne, where $11,000 to $11,500 is typical for an average bathroom. You will find cheaper averages in Adelaide and Hobart, ranging from $9,000 to $9,200.

Some of the biggest items that push up your bathroom renovation cost are waterproofing, tiling, and plumbing relocation. Waterproofing cannot be skimped on, and needs to be included in your planning from the get-go, at $50 to $80 per square metre. Tile supply runs from $35 to $120 per square metre with tiling labour costing another $50 to $70 per square metre. A licensed plumber will bill between $80 to $120 per hour and you can expect to pay between $80 and $130 per hour to a licensed electrician.

You can get away with just doing a few cosmetic changes — painting the walls a different colour, replacing accessories, fitting a new vanity, or swapping a showerhead. It costs significantly less than a complete bathroom renovation and is worth it if your layout works and plumbing does not need moving. That is where your budget goes furthest.

Smart Material Swaps That Cut Costs Without Cutting Corners

Once you are clear on your budget, you need to consider what materials you are using in your bathroom renovation, where you are spending, and where you can substitute.

Ceramic wall tiles start from as little as $12 per piece and are ideal for bathroom walls, with hard, easy-to-clean surfaces available in all kinds of textures and finishes. Porcelain tiles are lower porosity and more hardwearing, so are better for floors. Make sure you check the AS 4586 slip resistance P-rating before buying floor tiles, as the cheapest option may not be the wisest one.

For your vanity top, laminate benchtops will save you a serious amount compared to engineered stone. These days the finishes have come a long way — you get the look without the price tag. Whatever you do, don't cut corners on the waterproofing membrane. NCC 2022 requires shower walls to be waterproofed to at least 1800mm above the floor substrate, with a compliant membrane system throughout. Let the membrane fail and you're looking at mould, structural damage, and a repair bill that dwarfs what you saved.

Swap to an acrylic bath and you'll get something lighter, warmer underfoot, and far cheaper than cast iron — the visual difference is barely noticeable.

Bathroom Renovation Jobs You Can Do Yourself

Cheaper materials will only get you so far — rolling up your sleeves on some jobs yourself is the other big lever for keeping your diy bathroom renovation costs in check.

There's actually quite a bit you can legally take on yourself. You don't need a licensed trades (NCC 2022, ABCB Housing Provisions, Part 10.2)person to paint, fit towel rails and toilet roll holders, hang mirrors, swap a toilet seat, put together flat-pack vanity units, or change a showerhead. Every one of those tasks is worth $80 to $200 in labour savings, so it stacks up fast.

That said, plumbing connections, tapware installation, electrical work (including LED mirror wiring, heated towel rails, and exhaust fans), and waterproofing membranes are all jobs that need a licensed tradesperson — no exceptions across any Australian state or territory. Once those jobs are done, your licensed tradesperson must hand over compliance certificates. Have a go at this work yourself and you're not just risking injury — your insurance cover could be void if anything goes wrong.

Budget Bathroom Vanities Worth Considering

Your vanity has the biggest influence on the aesthetic of your bathroom, so it is worth focusing on even on a tight budget. low cost bathroom vanities have improved considerably in recent years. When selecting the cheapest bathroom vanity that still performs well, opt for a PVC cabinet rather than MDF, which is not waterproof.

Standard vanity widths of 600mm, 750mm, and 900mm will suit most spaces, so measure carefully before purchasing. Shaker-style doors tend to photograph well and make a cheap vanity look more expensive than it is. Lukka offers a broad range of PVC vanities from $300 to $600, and all perform very well.

Budget around $56 to $200 for a basin mixer and waste fitting to complete the installation. A counter-top basin with a wall-mounted mixer can deliver a boutique finish without the boutique price.

Small Bathroom Renovation Ideas

For a small bathroom renovation, design decisions are just as important as your budget. Australian bathrooms are typically under 5 square metres, so making the most of every centimetre matters. A wall-mounted vanity takes up minimal floor area and makes the room appear larger. Neutral, light colours such as off-white, cream, and light grey will brighten a small space visually. Larger wall tile formats can also make a bathroom appear more spacious. When a separate shower and bath cannot fit, a shower-over-bath is the most space-efficient option, and a recessed shower niche adds storage without consuming floor space.

Lighting is also worth considering in a small bathroom renovation. An LED shaving cabinet starting at $390 combines storage and lighting in one fixture. Alternatively, tile resurfacing (sometimes called re-enamelling) can work well on walls in good structural condition, typically costing $300 to $700 for a small bathroom.

FAQs

From start to finish, how long should a cosmetic-only bathroom refresh realistically take?

For a competent DIYer, a cosmetic refresh — fresh paint, a vanity swap, new accessories, and a showerhead change — should come in at one to two weekends, provided everything's ordered and on-site beforehand. If a licensed plumber is needed for tapware connections, tack on at least an extra day — trade availability alone can blow out your timeline.

Could resurfacing your existing tiles be a smarter move than ripping them out and starting fresh?

On walls that are structurally sound, tile resurfacing (sometimes called re-enamelling) can be a solid option — expect to pay $300 to $700 for a small bathroom. Floors are a different story — the coating wears fast under foot traffic and turns into a slip hazard, so new floor tiles are the smarter long-term call.

Is it possible to split a cheap bathroom renovation across two separate budgets instead of doing it all at once?

Yes — and plenty of Australians do exactly that. Get the waterproofing, tiling, and plumbing done first — they're the messy, compliance-driven jobs that need to happen early. Mirrors, lighting, and accessories can all wait for a second stage when the budget allows — none of it means touching the walls again.
