Typical bathroom renovation cost breakdown
In 2026, a typical bathroom renovation cost in Australia ranges from $15,000 to $35,000 for a standard-sized bathroom (roughly 5 to 8 square metres). This mid-range figure assumes you’re updating an existing bathroom with quality fittings and finishes, but not going for ultra-premium materials or significant structural changes.
The breakdown of where your money goes in a standard bathroom renovation typically looks like this:
- Labour: 40–50% ($6,000–$17,500) — includes plumbers, electricians, tilers, and builders
- Fixtures and fittings: 20–25% ($3,000–$8,750) — toilet, vanity, tapware, shower screen, bath
- Tiles and flooring: 15–20% ($2,250–$7,000) — wall and floor tiles plus waterproofing
- Plumbing and electrical: 10–15% ($1,500–$5,250) — relocating fixtures, new wiring, compliance upgrades
- Other materials: 5–10% ($750–$3,500) — paint, silicone, grout, adhesives, accessories
Regional variations do apply. Sydney and Melbourne homeowners often see costs at the higher end of this spectrum, while regional areas in Queensland and South Australia may come in 10–20% lower. According to data from the Australian Bureau of Statistics, building and renovation costs have risen steadily, making accurate budgeting more critical than ever.
How bathroom size affects renovation costs
Size plays a significant role in determining the typical bathroom renovation cost for your project. A small ensuite will naturally cost less than a spacious family bathroom, but the per-square-metre rate can actually be higher for tiny spaces due to fixed costs that don’t scale down proportionally.
Small bathroom (3–5 sqm): $10,000–$20,000. This includes powder rooms and compact ensuites. While the total spend is lower, you’re still paying for essential fixtures, labour, and waterproofing. If you’re renovating a particularly small space, check out our guide on small bathroom renovation costs for more specific advice.
Standard bathroom (5–8 sqm): $15,000–$35,000. This is where the typical bathroom renovation cost figures apply. You have room for a separate shower and bath, decent vanity space, and enough tile area to make an impact without blowing the budget.
Large bathroom (8+ sqm): $30,000–$60,000+. Master ensuites and family bathrooms at this size often include double vanities, freestanding baths, separate shower zones, and luxury finishes. Material costs increase significantly, and so does labour time for tiling and installation.
Keep in mind that layout changes—moving plumbing walls, relocating the toilet or shower—can add $3,000–$8,000 to any bathroom size. If your existing layout works reasonably well, keeping fixtures in roughly the same spots is one of the easiest ways to control costs.
Cost variations by scope and quality
The typical bathroom renovation cost depends heavily on the scope of work and the quality level you choose. Here’s how different approaches affect your bottom line:
Budget refresh ($5,000–$12,000)
This isn’t a full renovation—it’s a cosmetic update. You might replace the vanity, repaint, install a new shower screen, and update tapware and accessories. Existing tiles stay, and plumbing remains untouched. Perfect if your bathroom is structurally sound but aesthetically tired.
Mid-range renovation ($15,000–$35,000)
This is the typical bathroom renovation cost bracket for most Australian homeowners. You’re getting new tiles throughout, updated fixtures from reputable brands (Caroma, Reece house brands, Methven), proper waterproofing, and quality labour. Expect semi-frameless shower screens, stone or engineered stone benchtops on the vanity, and decent tapware. The result looks professional and will last 15–20 years with proper maintenance.
Premium renovation ($40,000–$80,000+)
Here you’re choosing designer fixtures, imported tiles, custom cabinetry, underfloor heating, rainfall showerheads, freestanding stone baths, and premium finishes like marble or large-format porcelain. Labour costs also rise because premium materials often require specialist installation. This tier makes sense if the rest of your home is high-end or you’re renovating to sell in a prestige market.
Material choices have the biggest impact on where you land in this range. A standard 600×600mm porcelain tile costs $30–$60 per square metre, while imported Italian porcelain or natural stone can run $150–$300 per square metre. Similarly, a basic acrylic bath is $400–$800, but a freestanding stone resin bath starts at $2,500 and climbs from there.
Hidden costs in typical bathroom renovations
Even when you’ve carefully budgeted for the typical bathroom renovation cost, unexpected expenses can appear. Being aware of these ahead of time helps you set aside a realistic contingency—most experienced renovators recommend adding 10–20% to your quoted price.
Structural issues: Once walls and floors are opened up, problems like rotted timber frames, subfloor damage, or termite damage may be discovered. Repairing these issues isn’t optional—it’s essential for a safe, compliant renovation. Budget $1,500–$5,000 as contingency for structural surprises.
Asbestos removal: In homes built before 1990, particularly pre-1980s bathrooms, asbestos-containing materials (fibro sheeting, vinyl flooring, textured paint) are common. Licensed removal costs $1,000–$4,000 depending on the extent. This is a legal requirement outlined by Safe Work Australia.
Compliance upgrades: Modern plumbing and electrical codes may require upgrading old systems. Safety switches (RCDs), waterproofing to current Building Code of Australia standards, and proper ventilation (exhaust fans) are non-negotiable. These compliance items can add $1,500–$3,000 to your project.
Access difficulties: If your bathroom is upstairs, has narrow doorways, or requires material hoisting, labour costs rise. Removing and disposing of old fixtures, tiles, and fittings from difficult-access properties can add $500–$1,500 to demolition costs.
Fixture lead times: Custom or imported fixtures may have 8–16 week lead times. If your tradies are ready but your bath hasn’t arrived, you’re paying for delays and potential rescheduling. Always confirm delivery dates before demolition begins.
One often-overlooked cost is temporary bathroom access. If you’re renovating your only bathroom, you may need to organise portable facilities ($150–$250 per week) or make arrangements to use a neighbour’s or gym bathroom for the 2–4 weeks of active work.
Common mistakes to avoid
Understanding the typical bathroom renovation cost is one thing; avoiding expensive missteps is another. Here are the most common mistakes that blow budgets and timelines:
Skipping the waterproofing: Proper waterproofing is legally required in wet areas and must be performed by licensed professionals. Cutting corners here leads to water damage, mould, and potentially having to redo the entire bathroom. Waterproofing typically costs $1,200–$2,500 and is worth every cent.
Choosing tiles before planning the layout: Falling in love with a tile before measuring your space often leads to excessive wastage or awkward cuts. Tiles should be selected after your bathroom layout is finalised, with careful consideration of where cuts will land. A good tiler can save you 10–15% in material costs through smart planning.
Underestimating ventilation needs: Poor ventilation leads to mould, peeling paint, and deteriorating fixtures. Australian building codes require either a window with adequate openable area or a mechanical exhaust fan. Retrofitting ventilation after tiling is expensive, so get it right from the start.
Ignoring storage: A beautiful bathroom that lacks practical storage becomes frustrating daily. Factor in recessed niches in the shower ($300–$600), adequate vanity drawers, and perhaps a mirrored shaving cabinet. These add $800–$2,000 to the typical bathroom renovation cost but dramatically improve functionality.
Going too trendy: While statement tiles and bold colours look great in magazines, they date quickly. If you’re planning to stay in your home long-term or sell within 5–10 years, neutral palettes with timeless fixtures offer better value. Save trend-led choices for easily changed elements like paint, accessories, and soft furnishings.
Not getting multiple quotes: Accept at least three detailed quotes from licensed, insured contractors. The cheapest isn’t always best—look for clear scope of works, itemised pricing, and realistic timelines. Check licenses via your state’s building authority and ask for references from recent bathroom jobs.
FAQ
What is the typical bathroom renovation cost in Australia in 2026?
The typical bathroom renovation cost for a standard-sized bathroom (5–8 square metres) ranges from $15,000 to $35,000. This covers mid-range fixtures, quality tiles, proper waterproofing, and professional labour. Smaller bathrooms may cost $10,000–$20,000, while larger or premium renovations can exceed $40,000.
How long does a typical bathroom renovation take?
Most standard bathroom renovations take 2–4 weeks once work begins. This includes demolition (1–2 days), rough plumbing and electrical (2–3 days), waterproofing (2–3 days including cure time), tiling (3–5 days), fixture installation (2–3 days), and finishing touches. Delays due to material shortages, structural issues, or poor weather can extend timelines.
Can I reduce the typical bathroom renovation cost without sacrificing quality?
Yes. Keep the existing layout to avoid costly plumbing relocation, choose quality mid-range fixtures rather than premium brands, do your own demolition if you’re capable, and shop around for tiles during sales. Avoiding structural changes and doing prep work yourself can save $2,000–$5,000 without compromising the finished quality.
Do I need council approval for a bathroom renovation?
Most bathroom renovations don’t require council approval if you’re working within the existing footprint and not altering the building’s structure or external appearance. However, you will need licensed plumbers and electricians, and all work must comply with the Building Code of Australia. If you’re adding a bathroom, moving external walls, or significantly changing plumbing, check with your local council.
Should I renovate my bathroom before selling my home?
A well-executed bathroom renovation typically returns 60–80% of its cost in added property value, but this varies by market and existing condition. If your bathroom is dated or damaged, a mid-range renovation can help your home sell faster and for a better price. However, over-capitalising with a premium renovation in a modest neighbourhood rarely pays off. Compare your typical bathroom renovation cost against recent comparable sales in your area.
Planning a bathroom renovation requires balancing your vision, budget, and practical needs. By understanding the typical bathroom renovation cost breakdown and the factors that influence pricing, you’re well-equipped to have informed conversations with contractors and make decisions that deliver lasting value. Start by getting detailed quotes, clarifying exactly what’s included, and setting aside a realistic contingency for the unexpected. Your refreshed bathroom is closer than you think.
