Thinking about renovating your bathroom? Smart move. But before you start pinning tiles and dreaming about rain showers, you need to know what it’s actually going to cost. Most Perth quotes you’ll find online are vague, and that doesn’t help you budget.
This guide breaks it all down: project size, tile choice, waterproofing, labour. All in real AUD figures. No fluff.
Average Bathroom Renovation Cost in Perth in 2026
Here’s the quick overview:
| Project Type | Estimated Cost (AUD) |
| Cosmetic refresh (no retile) | $3,000 – $5,000 |
| Standard bathroom (8–10 m²) | $8,000 – $15,000 |
| Small bathroom renovation | $5,000 – $10,000 |
| Full ensuite renovation | $10,000 – $20,000+ |
These are honest ranges. Your final quote depends on your specific bathroom, tile selection, and what’s already in place.
Standard Bathroom Renovation (8–10 m²) — What to Expect to Pay
A standard Perth bathroom reno typically covers:
- Demo and removal
- Waterproofing (mandatory in WA under AS 3740)
- Tiling — floor and walls
- New fixtures: vanity, toilet, shower screen
- Plumbing connections and finishing
Budget $8,000 – $15,000 for a quality result. Perth tiling labour runs roughly $50–$80/hr for experienced tradespeople in the metro area.
Small Bathroom Renovation Cost Perth
Small bathrooms (under 5 m²) cost less overall, but not always less per square metre. Tight spaces make for more complex, slower work.
- Standard small bathroom refresh: $5,000 – $8,000
- Full small bathroom renovation: $8,000 – $12,000
Going smaller doesn’t mean going quicker. Waterproofing, plumbing tie-ins, and fixture replacements take similar time regardless of floor area.
Full Ensuite Renovation Cost Perth
A full ensuite reno is usually the most expensive per square metre because:
- Wall tiling often goes full height
- Premium fixtures are typically chosen
- Layout changes can mean replumbing
Expect to budget $10,000 – $20,000+ for a quality full ensuite renovation in Perth.
What’s Included in a Bathroom Renovation Quote in Perth?
Tiling Costs — Labour and Materials
Tiles are one of the biggest cost variables. Here’s a rough guide:
| Tile Type | Material Cost Per m² (AUD) |
| Ceramic | $25 – $50 |
| Porcelain | $50 – $100 |
| Large format (600×1200+) | $80 – $150+ |
| Natural stone | $100 – $250+ |
Add tiling labour of roughly $50 – $90 per m² for standard wall and floor tiling in Perth.
Waterproofing Add-On Cost (AS 3740)
This is non-negotiable in WA. Under AS 3740 (the Australian Standard for waterproofing in wet areas), your shower and wet areas must be waterproofed by a licensed applicator — and it must be inspected before tiling starts.
Budget:
- Waterproofing labour and materials: $500 – $1,500 depending on the wet area size
Skipping or skimping on waterproofing is one of the most costly mistakes Perth homeowners make. It leads to leaks, mould, and expensive structural repairs. Don’t cut corners here.
Plumbing, Fixtures and Final Finishing
These add up fast. Don’t leave them out of your budget:
| Item | Estimated Cost (AUD) |
| Plumber (fixture swap) | $500 – $1,500 |
| New vanity | $400 – $2,000 |
| Toilet suite | $300 – $1,000 |
| Shower screen | $400 – $1,500 |
| Towel rails and accessories | $150 – $500 |
What Affects the Price of Your Bathroom Renovation?
Bathroom Size and Layout Complexity
Bigger = more materials. Complex = more labour.
Moving a wall or relocating a floor drain can add $2,000–$5,000+ to a quote compared to a straight tile-swap renovation.
Tile Choice — Ceramic vs Porcelain vs Large Format
- Ceramic — affordable, works well in most bathrooms
- Porcelain — more durable, moisture-resistant, ideal for Perth’s climate
- Large format tiles — fewer grout lines and easier to clean, but harder to install, which pushes labour costs up
DIY vs Hiring a Professional in Perth
Let’s be honest, some tasks are fine to DIY. Others are not.
| Task | DIY OK? | Why It Matters |
| Painting walls | Yes | Low risk |
| Installing accessories | Yes | Simple |
| Tiling | Risky | Poor prep = hollow tiles and cracking |
| Waterproofing | No | Must be licensed under WA law |
| Plumbing | No | Must be licensed in WA |
A bad DIY tile job can fail within 12 months. A bad waterproofing job can cost $20,000+ in water damage. Hire a professional where it counts.
Waterproofing Requirements
AS 3740 applies to all wet areas in Western Australia, regardless of bathroom size. Even a tiny ensuite needs properly applied, inspected waterproofing. Don’t let any tradie skip this step or quote around it.

FAQs — Bathroom Renovation Costs in Perth
Is a bathroom renovation worth it in Perth’s property market?
Yes, in most cases. A clean, modern bathroom adds real perceived value to a Perth home. Buyers notice bathrooms and dated ones are a red flag during inspections.
Can I renovate in stages to spread the cost?
Technically yes, but not always efficiently. Waterproofing and tiling need to happen together. You can’t tile now and waterproof later. Stage it logically: complete the wet area fully in phase one, do cosmetic upgrades in phase two.
What is the cheapest way to renovate a bathroom in Perth?
- Keep the existing layout (avoid moving plumbing)
- Use ceramic tiles over porcelain
- DIY the painting and accessory installation
- Get multiple quotes and compare
- Avoid peak summer timelines when Perth trades are busy
