What counts as a simple bathroom renovation
A simple bathroom renovation typically means you’re keeping the existing layout intact—no moving plumbing, no structural changes, and no major electrical rewiring. The focus is on cosmetic updates and replacing worn-out fixtures while working with the footprint you already have.
Common elements of a simple renovation include painting walls, replacing the vanity and basin, installing a new toilet, swapping out tapware and showerheads, re-grouting or replacing tiles in select areas, updating lighting fixtures, and adding new mirrors or storage. Because you’re not relocating the shower or toilet, you avoid the major plumbing and waterproofing expenses that push full bathroom renovations into five-figure territory.
The beauty of this approach is that you can achieve a dramatic visual transformation without the disruption and expense of a complete rebuild. Many homeowners use simple renovations to modernise dated bathrooms in preparation for sale, or simply to enjoy a fresher space without undertaking a months-long project.
Simple bathroom renovation cost breakdown
Across Australia in 2026, a simple bathroom renovation cost typically ranges from $5,000 to $12,000 for a standard-sized bathroom (around 5–7 square metres). This assumes you’re keeping the existing layout and focusing on surface-level updates and fixture replacement.
Here’s how the budget typically breaks down:
Vanity and basin: A quality pre-assembled vanity unit with integrated basin runs $600–$2,000, depending on size and finish. Wall-hung vanities with stone tops sit at the higher end, while freestanding laminate units are more affordable. Installation by a licenced plumber adds $300–$600.
Toilet: A new close-coupled toilet costs $200–$800 for the suite itself. Back-to-wall models with concealed cisterns are pricier. Plumber installation is typically $250–$450, assuming no drainage relocation.
Tapware and fixtures: Basin mixer taps range from $80–$400, shower mixers $150–$600. Budget $100–$250 for a handheld showerhead or $300–$800 for a rainfall head with arm. Installation is usually included in your plumber’s hourly rate.
Tiling: If you’re refreshing tired tiles, expect $40–$100 per square metre for basic ceramic tiles, or $80–$150/m² for porcelain or feature tiles. Labour for tiling is $45–$80/m². A typical simple renovation might re-tile the shower recess or a feature wall rather than the entire room, keeping costs in the $800–$2,500 range.
Painting: A professional paint job for a standard bathroom (walls and ceiling, not tiles) costs $400–$900 including materials. Use moisture-resistant paint with anti-mould additives—brands like Dulux Wash & Wear or Taubmans Endure are popular Australian choices.
Lighting and ventilation: Replacing an old exhaust fan with a modern low-noise model costs $150–$400 for the unit plus $200–$400 for electrician installation. LED downlights run $30–$80 each; budget $100–$200 per light point for installation by a licenced sparky.
Mirrors and accessories: A frameless mirror costs $150–$500 depending on size. Towel rails, toilet roll holders, and robe hooks add another $100–$300 for mid-range fittings.
Labour: If you’re hiring tradespeople for the full scope, allow $2,000–$4,500 for labour across plumbing, tiling, electrical, and painting. Rates vary by region—Sydney and Melbourne typically sit 10–15% higher than regional areas.
According to the Australian Bureau of Statistics, construction input costs have risen steadily, so always request updated quotes rather than relying on older estimates.
Factors that affect your budget
Several variables can push a simple bathroom renovation cost toward the higher or lower end of the spectrum.
Bathroom size: A compact ensuite (3–4 m²) will naturally cost less than a family bathroom (6–8 m²), particularly for tiling and painting where you’re charged per square metre.
Fixture quality: Entry-level fixtures from Bunnings or Reece trade ranges keep costs down, while designer brands (Caroma, Methven, Parisi) can double or triple fixture budgets. The good news: even mid-range Australian brands offer excellent quality and local warranties.
Tile choice: Simple white subway tiles are affordable and timeless at $40–$60/m². Large-format porcelain, hexagonal mosaics, or imported feature tiles can exceed $150/m². Your choice dramatically impacts material costs.
Location: Metro areas command higher trade rates. A plumber in Sydney might charge $95–$120 per hour, compared to $70–$90 in regional Queensland. The simple bathroom renovation cost in Melbourne or Sydney will typically run 15–20% higher than in Hobart or Adelaide for identical work.
Condition of existing surfaces: If your walls are already in good shape and just need paint, you’ll save considerably. Walls requiring patching, mould remediation, or moisture barrier upgrades will add $500–$1,500 to your budget.
Waterproofing requirements: Even in a simple renovation, if you’re re-tiling a wet area you must meet Australian Standards AS 3740 for waterproofing. Quality membrane systems and proper installation add $800–$1,800 depending on the area covered. This is non-negotiable—skipping it risks expensive water damage and failed building inspections.
Access and waste removal: A ground-floor bathroom with easy access is straightforward. An upstairs bathroom with narrow staircases or a unit on the fifth floor without a lift increases labour time and skip bin costs. Budget an extra $200–$600 for difficult access scenarios.
DIY vs professional labour costs
One of the biggest levers you can pull to reduce simple bathroom renovation cost is tackling tasks yourself. But it’s crucial to understand where DIY makes sense and where you legally need licenced tradespeople.
What you can DIY: In most Australian states, homeowners can legally paint, remove old fixtures (after a plumber has disconnected them), install mirrors and accessories, remove non-structural cabinetry, and prepare surfaces. These tasks can save you $1,000–$2,000 in labour if you’re handy and have time.
What requires licenced trades: Under Australian building regulations, all plumbing work must be performed by a licenced plumber, electrical work by a licenced electrician, and gas work by a licenced gas fitter. This isn’t optional—unlicenced work voids insurance, creates safety hazards, and can make your home unsaleable. Waterproofing in wet areas must also be certified compliant with Building Code of Australia standards.
Hybrid approach: Many homeowners save money by doing demolition, painting, and simple installations themselves while hiring professionals for plumbing, electrical, tiling, and waterproofing. This hybrid approach can reduce your simple bathroom renovation cost by 20–30% while keeping the project compliant and safe.

Common mistakes to avoid
Skipping proper ventilation: Many Australians underestimate the importance of bathroom ventilation. Without adequate exhaust, moisture leads to mould, peeling paint, and rotting timber. A quality exhaust fan ducted to the exterior is essential—don’t rely on a window alone, especially in humid climates.
Choosing style over function: That stunning but shallow vanity might look beautiful in the showroom, but if it doesn’t provide adequate storage, you’ll regret it daily. Similarly, a rainfall showerhead looks luxurious but may not provide enough pressure in homes with older plumbing.
Ignoring waterproofing standards: Cutting corners on waterproofing to save a few hundred dollars is false economy. Water damage can cost tens of thousands to remediate. Always insist on certified waterproofing compliant with AS 3740, and get a compliance certificate for your records.
Underestimating timeline: Even a simple renovation takes 1–3 weeks if you’re using multiple trades. Rushing tradespeople or trying to use the bathroom before grout and sealant have properly cured leads to poor results and costly rework.
Forgetting about lighting: Bathrooms need task lighting around mirrors and ambient lighting for safety. Many renovations focus on fixtures and finishes but leave the original single downlight, resulting in a shadowy, unwelcoming space. Budget for proper lighting from the start.
Not obtaining quotes from multiple trades: Prices vary significantly between contractors. Always get at least three written quotes that break down materials and labour separately. This helps you identify where you’re paying premium prices and where you might negotiate or substitute products.
Overlooking storage: After investing in a new vanity and fixtures, don’t leave towels and toiletries scattered on the floor. Plan for wall-mounted cabinets, recessed niches in the shower, or a mirrored shaving cabinet. Storage solutions are far easier to incorporate during renovation than to retrofit later.
FAQ
What is the average simple bathroom renovation cost in Australia?
In 2026, most Australian homeowners spend between $5,000 and $12,000 on a simple bathroom renovation that updates fixtures, surfaces, and finishes without changing the layout. Costs vary by location, bathroom size, and the quality of materials chosen. Regional areas typically sit at the lower end, while Sydney and Melbourne projects trend higher.
Can I renovate a bathroom for under $5,000?
Yes, with careful planning and DIY effort. Focus on painting, replacing the vanity and toilet yourself (with a plumber for connections), installing new tapware, re-grouting existing tiles, and updating lighting. You’ll need to shop budget ranges and do much of the non-licenced work yourself, but a fresh, functional bathroom for $3,500–$5,000 is achievable in a small space.
How long does a simple bathroom renovation take?
Expect 1–3 weeks for a straightforward renovation with no layout changes. The timeline depends on whether you’re re-tiling (which requires drying and curing time), the availability of tradespeople, and whether you’re doing some work yourself. Always allow a buffer—unexpected issues like hidden water damage or delayed product deliveries can add days.
Do I need council approval for a simple bathroom renovation?
Generally no, provided you’re not moving walls, changing the footprint, or altering structural elements. Cosmetic updates and like-for-like fixture replacement are usually exempt from council approval in most Australian jurisdictions. However, you must still comply with building standards for waterproofing and use licenced tradespeople for plumbing and electrical work. Check with your local council if you’re uncertain.
What’s the difference between a simple and full bathroom renovation?
A simple renovation updates finishes and fixtures within the existing layout—new vanity, paint, tiles, and fittings without moving plumbing. A full bathroom renovation typically involves layout changes, relocating plumbing fixtures, full re-tiling, new waterproofing throughout, and often structural work. Full renovations cost $15,000–$35,000+ and take 4–8 weeks, while simple projects are faster and more budget-friendly.
Should I replace my bathtub or keep it?
If your bath is in good condition and you use it regularly, keep it and save $1,500–$3,000. A simple re-enamel or professional clean costs $400–$800 and makes an old bath look new. If the bath is cracked, rarely used, or you prefer a larger shower, replacement makes sense—but remember that changing from bath to shower involves waterproofing, tiling, and plumbing changes that push you beyond a “simple” renovation budget.
A simple bathroom renovation strikes the perfect balance between impact and investment. By focusing on updates that matter—fresh fixtures, clean surfaces, and improved lighting—you can transform a tired bathroom into a space you’ll enjoy every day, all while keeping your simple bathroom renovation cost firmly within reach. Plan carefully, invest in quality where it counts (waterproofing and fixtures), and don’t hesitate to tackle appropriate tasks yourself. With realistic expectations and good tradespeople, your refreshed bathroom will deliver years of value and comfort.
