How Much Does a Bathroom Renovation Cost in Australia?

Renovating your bathroom can be one of the most transformative home improvement projects — both in terms of daily comfort and property value. But before you rip out tiles and fixtures, one of the first questions most homeowners ask is: How much will this actually cost? Let’s break it down.

Average Bathroom Renovation Costs in Australia

Bathroom renovation costs in Australia vary widely depending on the size of the space, the extent of the work, and the quality of materials you choose. According to industry data, the average bathroom renovation sits around $25,000–$50,000, but your actual spend could fall below or above this range based on your goals.

Here’s a snapshot of typical price ranges for 2025–2026:

Renovation Type	Estimated Cost (AUD)
Budget / Cosmetic Refresh	$10,000 – $20,000+
Mid-Range Renovation	$25,000 – $40,000+
High-End / Luxury Renovation	$40,000 – $55,000+
Premium Projects (mico cement, marble tiles)	$55,000 – $80,000+

Key takeaway: A basic refresh (new fixtures, paint, minor changes) is affordable, while a full overhaul with premium finishes and structural changes can be a significant investment.

What Determines Bathroom Renovation Cost?

A bathroom is deceptively complex — it’s one of the few rooms in your home that deals with water, electricity, tiling across walls and floors, and multiple specialised trades (plumber, electrician, tiler, waterproofing specialist, etc.). Here’s what drives the price:

1. Size & Layout

Larger bathrooms require more materials and labour. Changing the layout (e.g., moving the shower or toilet) adds significantly to cost due to extra plumbing and drainage work.

2. Scope of Works

• Cosmetic refresh: Just updating tiles, vanity, or fittings.
• Partial renovation: Re-tiling, replacing fixtures, minor plumbing.
• Full renovation: Strip-out, waterproofing, new layout, structural changes.

3. Materials & Fixtures

Fixtures and finishes vary dramatically in price:

• Budget tiles: $20–$40/m²
• Mid-range porcelain: $40–$70/m²
• Designer stone-look tiles: $80–$150+/m²
• Vanity units, toilets, showers & tapware can range from a few hundred to several thousand dollars each.

4. Labour & Trades

Labour often makes up 40–60% of your budget — involving plumbers, electricians, tilers, waterproofers, carpenters and sometimes designers.

5. Waterproofing & Compliance

Waterproofing is essential and legally required under Australian standards. Cutting corners here can lead to leaks and expensive repairs later — so budget at least several hundred to a few thousand dollars depending on bathroom size.

Typical Cost Breakdown

Here’s how costs can stack up in a typical renovation:

Component	Estimated Range
Demolition & waste removal	$500 – $3,000
Carpentry	$4,000 - $10,000
Plumbing work	$2,000 – $6,000+
Electrical work	$800 – $4,000
Waterproofing	$800 – $1,500
Tiling (walls + floors)	$3,000 – $10,000
Fixtures & fittings	$2,000 – $10,000+
Vanity & cabinetry	$1,500 – $8,000
Painting & finishing	$300 – $2,000

Examples by Renovation Type

Budget / Cosmetic Refresh

Ideal if you want to freshen up your bathroom without major changes. Typical work includes:

• Painting
• New tiles or re-grouting
• New vanity and tapware
  Budget: $10,000 – $20,000+

Mid-Range Renovation

A complete update without luxury finishes. You might:

• Retile walls/floors

Tips to Save on Your Renovation

Keep existing layout: Moving fixtures can add thousands of dollars.
Choose quality mid-range finishes: They look great and last longer.
Build a contingency buffer: Always budget 10–15% extra for surprises.

Final Thoughts
