Small bathroom renovation cost breakdown
In 2026, Australian homeowners can expect to pay between $8,000 and $18,000 for a small bathroom renovation, depending on the scope and quality of finishes. This typically covers a bathroom of 3–5 square metres—think standard apartment bathrooms, ensuite spaces, or compact powder rooms in older homes.
Here’s how the typical small bathroom renovation cost breaks down by trade and element:
- Demolition and removal: $800–$1,500. This includes stripping out old tiles, fixtures, and disposing of waste.
- Plumbing: $1,500–$3,500. Moving pipes, installing new taps, shower mixers, and connecting fixtures. If you’re keeping the same layout, costs sit at the lower end.
- Electrical: $800–$1,800. Lighting, exhaust fan, heated towel rails, and waterproof power points.
- Tiling:$2,000–$5,000. Wall and floor tiles including labour. Budget tiles can drop this to $1,500, while premium porcelain or stone pushes it higher.
- Vanity and basin: $600–$2,500. Stock vanities start around $600; custom joinery can exceed $3,000.
- Shower screen: $400–$1,200. Frameless glass sits at the top end, semi-frameless or framed are more affordable.
- Toilet: $200–$800 for the suite itself; installation is usually included in plumbing costs.
- Painting and finishing: $400–$900. Includes ceiling, trim, and moisture-resistant paint.
- Waterproofing: $800–$1,500. Non-negotiable in wet areas and mandated by the Building Code of Australia.
These figures assume a standard refresh—new tiles, fixtures, and fittings—without major structural changes. If you’re considering a more modest update, our guide on low-cost bathroom renovation offers budget-friendly alternatives.
Factors affecting your renovation cost
Not all small bathroom renovations are created equal. Several variables can push your small bathroom renovation cost up or down significantly.
Layout changes
Keeping the existing plumbing layout is the single best way to control costs. Moving a toilet, shower, or basin means relocating drains and water supply lines, which can add $2,000–$5,000 in plumbing alone. If your current layout works, resist the temptation to shift things around.
Material selection
Tiles are a major cost driver. Standard ceramic tiles cost $30–$60 per square metre installed, while large-format porcelain or natural stone can reach $120–$200 per square metre. Similarly, tapware ranges from $150 for basic chrome mixers to over $800 for designer European brands. Choose mid-range fittings from reputable Australian suppliers—you’ll get quality and warranty support without the prestige markup.
Labour and location
Tradesperson rates vary across Australia. In Sydney and Melbourne, expect to pay 15–25% more than in regional areas. A tiler in metropolitan Brisbane might charge $60–$80 per square metre, whereas in a regional centre you could find quotes closer to $50–$65. Small bathrooms actually cost more per square metre to renovate than larger ones because tradespeople still need the same setup time and site visits.
Structural and compliance work
Older homes—especially those built before 1990—may need additional work to meet current building codes. Asbestos sheeting in walls or floors requires licensed removal ($1,500–$3,000). Poor ventilation demands upgraded exhaust fans or even new windows. Factor in a 10–15% contingency for unknowns if your home is more than 30 years old.
Custom features
Luxuries like underfloor heating ($800–$1,500), a niche shelf in the shower ($300–$600), or a floating vanity with integrated LED lighting can enhance the space but will lift your budget. Prioritise features that genuinely improve daily use over aesthetic flourishes.

Cost-saving strategies that work
You don’t need to compromise on quality to keep your small bathroom renovation cost under control. These practical strategies can save thousands without sacrificing longevity or style.
Stick with the existing layout
We’ve mentioned it already, but it bears repeating: avoid moving plumbing fixtures. Every time you relocate a drain or water line, you’re adding both labour and materials. If your current layout is functional, invest your savings in better tiles or fixtures instead.
Shop smart for materials
Big-box hardware stores often run seasonal sales on bathroom fittings. You can also find excellent deals on overstock tiles from importers and trade suppliers. Buy your own materials and supply them to your tradesperson—you’ll avoid their markup (typically 10–20%) and have better control over quality. Just ensure everything arrives on-site before trades are booked.
Tackle cosmetic tasks yourself
Demolition, painting, and even simple tasks like removing old silicone can be handled by a confident DIYer. Stripping out tiles and disposing of rubble yourself could save $800–$1,200. Just leave licensed work—plumbing, electrical, waterproofing, and tiling—to the professionals. For context on which jobs to DIY, our article on DIY vs professional bathroom renovation cost breaks it down in detail.
Choose cost-effective materials
Rectified porcelain tiles in neutral tones offer a premium look at mid-range prices ($50–$80 per square metre). Luxury vinyl planks are waterproof, affordable, and increasingly popular for bathroom floors—though always check they’re rated for wet areas. Laminate or polyurethane vanities cost half the price of solid timber and stand up well to moisture when properly sealed.
Bundle trades and book off-peak
If you’re managing the project yourself, try to book multiple trades through one reliable contact who can coordinate the schedule. Tradies are often more flexible on pricing during winter (June–August) when demand is lower. A well-organised timeline also minimises downtime, which keeps labour costs lean.
Common mistakes to avoid
Small bathrooms leave little room for error—literally and financially. Avoid these pitfalls to keep your small bathroom renovation cost on track and your sanity intact.
Skimping on waterproofing
Waterproofing isn’t optional. Australian Standards AS 3740 sets out strict requirements for wet area membranes, and any licensed plumber or tiler should comply. Cutting corners here leads to water damage, mould, and expensive rectification work down the line. Always insist on a waterproofing certificate before tiling begins.
Choosing style over function
A freestanding bath might look stunning on Instagram, but in a 3-square-metre bathroom it will dominate the space and limit storage. Prioritise layout efficiency, ventilation, and practical storage before aesthetic features. Small spaces reward smart design over showy fixtures.
Ignoring ventilation
Poor ventilation accelerates mould growth, damages paint and joinery, and makes the room unpleasant to use. Install an appropriately sized exhaust fan (rated for the room’s cubic metres) vented to the outside—not into the roof cavity. According to Choice, inadequate bathroom ventilation is one of the top causes of mould complaints in Australian homes.
Underestimating the timeline
A small bathroom renovation typically takes 2–4 weeks, depending on complexity. Delays in material delivery, council inspections, or trade scheduling can stretch this out. If it’s your only bathroom, arrange alternative facilities with family, friends, or budget for temporary amenities. Rushing trades to meet an unrealistic deadline usually results in poor workmanship.
Failing to get proper quotes
Never proceed on a verbal estimate. Get itemised written quotes from at least three licensed contractors, check their references, and verify insurance and licensing through your state’s building authority. Cheaper isn’t always better—especially if it means unlicensed work that won’t pass inspection.
FAQ
What is the average small bathroom renovation cost in Australia?
In 2026, most Australians spend between $8,000 and $18,000 to renovate a small bathroom (3–5 square metres). Basic refreshes with budget materials start around $8,000, while mid-range finishes and quality fixtures typically cost $12,000–$15,000. Custom work, high-end tiles, and layout changes can push costs toward $20,000 or more.
How can I renovate a small bathroom on a tight budget?
Keep the existing plumbing layout, source your own materials during sales, and handle demolition and painting yourself. Opt for mid-range tiles, laminate vanities, and standard fixtures. Avoid custom joinery and unnecessary features like underfloor heating. A well-planned small bathroom renovation cost can be kept under $10,000 without compromising quality or compliance.
Do I need council approval for a small bathroom renovation?
Most cosmetic bathroom renovations (replacing tiles, fixtures, vanities) don’t require council approval, but you must use licensed plumbers and electricians who will obtain necessary compliance certificates. Structural changes—removing walls, altering drainage, or modifying ventilation—may trigger a building permit. Check with your local council or a building surveyor before starting work.
How long does a small bathroom renovation take?
Plan for 2–4 weeks from demolition to completion. The timeline depends on the scope of work, availability of trades, and material delivery. Jobs requiring structural work, asbestos removal, or council inspections take longer. Always allow a buffer—unexpected issues like hidden water damage or delayed fixtures can add several days.
Is it worth renovating a small bathroom before selling?
A fresh, modern bathroom adds appeal and can improve your sale price, particularly if the existing one is dated or damaged. Focus on neutral tiles, quality fixtures, and good lighting. According to recent data from the Australian Bureau of Statistics, bathroom and kitchen updates rank among the highest-return renovations for sellers. Just don’t overcapitalise—keep your small bathroom renovation cost proportional to your home’s overall value.
Understanding the true small bathroom renovation cost helps you plan confidently and avoid costly surprises. Whether you’re working with a modest budget or investing in quality finishes, focusing on smart layout, reliable trades, and durable materials will deliver a bathroom that looks great and functions flawlessly for years to come. Get multiple quotes, plan thoroughly, and don’t be afraid to ask questions—your renovation is an investment in daily comfort and long-term value.
