Average bathroom renovation cost breakdown
The average bathroom renovation cost in Australia sits between $18,000 and $28,000 for a standard-sized bathroom in 2026. This figure covers most urban areas including Sydney, Melbourne, Brisbane, Perth, and Adelaide, though regional variations do apply.
Here’s how that average breaks down across typical spend categories:
- Labour costs: $7,000–$12,000 (35–45% of total budget)
- Fixtures and fittings: $4,000–$8,000 (vanity, toilet, shower, tapware)
- Tiles and flooring: $2,500–$5,000 (materials plus installation)
- Plumbing: $2,000–$4,000 (relocations, new pipes, compliance work)
- Electrical: $1,500–$2,500 (lighting, heated towel rails, exhaust fans)
- Waterproofing: $1,200–$2,000 (membrane and compliance certification)
- Cabinetry and storage: $1,500–$3,000
- Painting and finishing: $800–$1,500
According to the Australian Bureau of Statistics, construction costs have risen approximately 4.2% annually over the past two years, which explains why figures from 2024 guides now need adjustment for 2026 planning.
These averages assume a bathroom measuring roughly 2.5m × 2.5m (6.25 square metres), which represents the typical main bathroom in Australian homes built from the 1980s onwards. Smaller ensuites typically cost 20–30% less, while large family bathrooms or those requiring structural changes can push well above $35,000.
What influences your bathroom renovation cost
Not all bathroom renovations cost the same, and understanding the variables helps you estimate more accurately for your specific project.
Bathroom size and layout changes
Larger bathrooms mean more tiles, more flooring, bigger vanities, and longer installation times. If you’re keeping the existing layout—toilet, shower, and basin stay in the same spots—you’ll save considerably on plumbing and waterproofing compared to moving fixtures around.
Relocating a toilet alone can add $1,500–$3,000 to your budget because of the waste pipe requirements and floor excavation involved. Moving plumbing in upper-storey bathrooms or older homes with outdated pipework compounds the complexity and cost.
Fixture quality and brands
The average bathroom renovation cost shifts dramatically based on your fixture selections. A basic vanity from Bunnings might cost $600, while a custom timber vanity with stone benchtop runs $3,500–$6,000. Similarly, shower screens range from $400 for a semi-frameless design to $2,500 for frameless 10mm glass.
European tapware brands (Grohe, Hansgrohe, Villeroy & Boch) command premium prices but offer superior build quality and longer warranties. Mid-tier Australian brands like Caroma and Methven deliver solid performance at more accessible price points.
Tiling choices and installation patterns
Tiles vary wildly in price—from $25 per square metre for basic ceramic to $200+ for large-format porcelain or natural stone. Installation costs typically add $50–$80 per square metre, but intricate patterns like herringbone, hexagonal mosaics, or feature walls with contrasting colours can push labour rates to $100+ per square metre.
Floor-to-ceiling tiling looks stunning but costs more than half-height tiling with painted upper walls. Many renovators balance aesthetics and budget by tiling wet zones fully and using moisture-resistant paint elsewhere.
Geographic location
Capital city tradespeople charge higher rates than regional counterparts. Sydney typically sits at the top end for labour costs, with tilers, plumbers, and electricians commanding daily rates 10–15% above the national average. Perth and Melbourne follow closely, while Adelaide and Hobart often offer better value.

Structural or compliance work
Older homes frequently need electrical upgrades to meet current Australian Standards (AS/NZS 3000), particularly around wet-area circuit protection. If your existing wiring lacks RCD protection or your switchboard needs upgrading, add $1,000–$2,500.
Ventilation is another compliance area—the National Construction Code requires adequate exhaust in bathrooms. Installing or upgrading an exhaust fan with ducting to the outside typically costs $400–$900.
Asbestos removal, if your home was built before 1990, can add $1,500–$5,000 depending on the extent of sheeting or backing boards that need professional removal.
Budget levels: economy, mid-range, and premium
Breaking average bathroom renovation cost into three tiers helps you understand what’s achievable at different investment levels.
Economy renovation: $10,000–$15,000
This budget suits cosmetic updates without layout changes. You’re keeping existing plumbing locations, choosing budget-friendly fixtures, and potentially handling some tasks yourself (demolition, painting, or simple installations if you’re competent).
Typical features include:
- Basic ceramic tiles
- Flat-pack or entry-level vanity
- Acrylic shower base with semi-frameless screen
- Standard Caroma or similar Australian-brand fixtures
- Minimal structural or electrical work
This tier works well for investment properties, first-home buyers, or anyone prioritising function over luxury.
Mid-range renovation: $18,000–$28,000
This is where the average bathroom renovation cost sits for most Australian homeowners. You get quality materials, professional tradespeople for all work, and some flexibility for minor layout tweaks.
Expect:
- Good-quality porcelain tiles with feature options
- Semi-custom or quality off-the-shelf vanity with stone or engineered stone top
- Frameless shower screen
- Mid-tier tapware and fixtures
- Proper waterproofing with certification
- Modern lighting including LED downlights
- Heated towel rail
This bracket delivers a bathroom that looks contemporary, functions reliably, and adds genuine value to your home.
Premium renovation: $30,000–$50,000+
High-end renovations incorporate luxury materials, custom cabinetry, designer fixtures, and often involve some structural changes or expansion. Premium projects might include underfloor heating, smart-home integration, bespoke tiling designs, or high-end stone surfaces.
Common premium inclusions:
- Large-format porcelain or natural stone tiles
- Custom-built vanity with premium stone benchtop
- Freestanding bath or high-end built-in spa
- European designer tapware and fixtures
- Underfloor heating
- Advanced ventilation and humidity control
- Architectural lighting design
- Custom frameless shower enclosures
These bathrooms become genuine lifestyle features and significantly enhance property value, particularly in established suburbs or prestige areas.
Hidden costs that blow budgets
Even when you’ve researched the average bathroom renovation cost thoroughly, unexpected expenses emerge. Planning for these keeps your project on track.
Permit and certification fees: Most bathroom renovations require council permits for plumbing and electrical work, plus waterproofing certification. Budget $500–$1,200 for compliance documentation. Some councils charge additional fees for building permits if you’re altering the structure.
Poor substrate conditions: Once demolition starts, you might discover rotted timber framing, damaged concrete, or previous water damage requiring repair. Structural timber replacement can add $800–$2,500, while concrete floor repairs cost $600–$1,500.
Temporary bathroom arrangements: If you only have one bathroom, you’ll need alternatives during the 2–3 week renovation. Some homeowners rent portable toilets ($150–$250 per week) or arrange gym memberships for showering.
Waste removal: Skip bin hire for a bathroom renovation typically costs $300–$600 depending on size and your location. Some contractors include this; others don’t, so clarify upfront.
Accessories and finishing touches: Towel rails, toilet roll holders, mirrors, shower caddies, and bathroom storage add up quickly. Budget an additional $500–$1,200 for these items that often slip through initial quotes.
Material wastage and cuts: Tiles require 10–15% extra for cuts and breakages. If you’ve calculated tile quantities exactly to your bathroom’s square metreage, you’ll likely come up short and face delays or mismatched batches if you need to reorder.
Common mistakes to avoid
Understanding the average bathroom renovation cost is one thing; avoiding costly errors is another. Here are the pitfalls that catch even experienced renovators.
Underestimating labour costs: Many first-time renovators focus on material prices and forget that labour typically consumes 35–45% of the budget. Always get detailed quotes that separate materials and labour so you understand the true cost breakdown.
Choosing fashion over function: That matte black tapware looks incredible in showrooms but shows water spots immediately and requires constant cleaning. Similarly, frameless glass may suit Instagram but needs regular maintenance in hard-water areas. Consider your lifestyle and maintenance tolerance when selecting finishes.
Skimping on waterproofing: This is not the place to cut corners. Inadequate waterproofing leads to structural damage, mould, and expensive rectification work. Insist on a licensed waterproofer who provides a compliance certificate—it’s legally required and protects your investment.
Ignoring ventilation: Poor ventilation causes mould, peeling paint, and premature fixture corrosion. An undersized or poorly positioned exhaust fan won’t adequately remove moisture. Specify a fan rated for your bathroom’s volume (measured in cubic metres) and ensure it vents directly outside, not into ceiling cavities.
DIY plumbing or electrical work: In Australia, plumbing and electrical work must be performed by licensed tradespeople. DIY attempts void your insurance, breach building codes, and can create dangerous situations. Even simple tasks like installing a new toilet require a licensed plumber’s certification.
Not planning for storage: Bathrooms accumulate towels, toiletries, cleaning products, and personal items. Inadequate storage leaves benchtops cluttered and the space feeling cramped. Include sufficient cabinetry, recessed niches, or shelving in your design from the outset.
Overlooking lighting design: A single ceiling light creates harsh shadows and unflattering illumination. Layer your lighting with task lights near mirrors, ambient ceiling lights, and possibly accent lighting for features. Dimmers add flexibility for different times of day.
Ignoring the bigger picture: If your kitchen is dated or other rooms need attention, pouring your entire renovation budget into a luxury bathroom creates imbalance. Sometimes a mid-range bathroom renovation plus updates elsewhere delivers better overall home improvement. Our kitchen renovation cost guide can help you compare and prioritise.
FAQ
What is the average bathroom renovation cost in Australia in 2026?
The average bathroom renovation cost ranges from $18,000 to $28,000 for a standard bathroom, with economy renovations starting around $10,000 and premium projects exceeding $35,000. Location, bathroom size, fixture quality, and layout changes all influence final costs.
How long does a typical bathroom renovation take?
Most bathroom renovations take 2–4 weeks depending on complexity. Simple cosmetic updates might finish in 10–14 days, while projects involving layout changes, structural work, or custom elements can extend to 5–6 weeks. Weather, material delivery delays, and tradesperson availability affect timelines.
Can I renovate a bathroom for under $15,000?
Yes, economy renovations are achievable in the $10,000–$15,000 range if you keep the existing layout, choose budget-friendly materials, and potentially handle demolition or painting yourself. Stick with standard fixture locations to avoid expensive plumbing modifications, and select mid-range Australian brands rather than premium imports.
Do I need council approval for a bathroom renovation?
Most bathroom renovations require plumbing and electrical compliance certificates, and waterproofing certification is mandatory in wet areas. Full building permits are typically needed if you’re altering the structure, moving walls, or significantly changing the layout. Check with your local council early in planning—requirements vary by state and municipality.
What adds the most value: bathroom or kitchen renovation?
Both add substantial value, but kitchens typically deliver slightly higher returns in Australian property markets—often recouping 60–80% of renovation costs at sale. Bathrooms return 50–70% on average. However, a dated or dysfunctional bathroom can actively deter buyers, so addressing serious bathroom issues often makes more sense than upgrading an already-adequate kitchen. The optimal strategy balances both spaces for a cohesive home presentation.
Should I renovate the bathroom before selling?
If your bathroom is genuinely outdated (1980s or earlier finishes), a mid-range renovation usually pays dividends by broadening buyer appeal and potentially lifting sale price. However, if your bathroom is reasonably modern and functional, a cosmetic refresh—new paint, updated fixtures, professional cleaning, and regrouting—might deliver better return on investment than a full renovation. Consider your local market and property price point.
Planning your bathroom renovation with a clear understanding of the average bathroom renovation cost puts you in control of the process. Allocate your budget wisely across quality fixtures, skilled tradespeople, and proper compliance work, and you’ll create a bathroom that serves your household beautifully for years to come. Get multiple quotes, verify licenses and insurance, and don’t rush decisions on finishes—a well-planned renovation beats a rushed one every time.
