What is the Average Bathroom Renovation Cost in Australia?

The average cost of a bathroom renovation in Australia falls between $10,000 and $50,000+, depending on the size of your space, the quality of materials you choose, and how much work is involved.

Let’s look at what three price brackets can realistically achieve:

Budget Bathroom Renovation ($8,000–$15,000)

If you’re working with a tighter budget, this range is perfect for small bathrooms, powder rooms, or simple upgrades to an old bathroom. You’ll be sticking to the existing layout and focusing on affordable changes that still make a big difference.

What you can typically do:

Replace the vanity, tapware, and showerhead
Paint over old bathroom tiles or regrout them for a fresh look
Use budget-friendly ceramic tiles or vinyl flooring
Install basic LED lighting and new bathroom accessories
Save with flatpack furniture or ex-display items

Best for: Quick updates, first homes, investment properties

Standard Renovation/Mid-range Renovation ($15,000–$35,000)

This is the most common renovation range for Australian homes. It gives you the flexibility to upgrade materials, make some minor layout changes, and create a space that feels more modern and functional.

What’s included:

Retiling floors and walls with stylish, durable tiles
Frameless or semi-frameless shower screens
Mid-range fixtures and fittings from trusted brands
Improved lighting, ventilation and waterproofing
Possibility to reposition fixtures like the toilet or vanity

Best for: Family homes, long-term updates, practical design upgrades

Premium or Luxury Bathroom Renovation ($35,000–$50,000+)

If you’re going all out, this is your category. Whether you’re creating a high-end ensuite or expanding your bathroom entirely, this range opens the door to custom design, smart features, luxury elements, and premium fittings that elevate the space.

What’s possible at this level:

Full layout redesign or expanding the space
Premium tiles like natural stone or porcelain slabs
Underfloor heating, spa bath, or smart toilet
Custom-built vanity with stone benchtops
Designer fixtures, recessed lighting, and more

Best for: Forever homes, high-end builds, or anyone after a resort-style finish

Factors That Influence Bathroom Renovation Costs

Bathroom renovations can cost anywhere from $8,000 to $35,000+, depending on:

The size of the bathroom
Whether structural work is needed
The cost and quality of tiles, fittings and fixtures
Additions like skylights or new windows
If plumbing or fixtures are being relocated
Whether it’s a renovation or a completely new build
Labour rates in your area
Permit or strata approval requirements
The extent of electrical work involved
Inclusion of premium features like underfloor heating or custom bathtubs
The number of trades required, such as electricians, tilers, or cabinetmakers

Bathroom Renovation Cost Breakdown

The average spend on a bathroom remodel in Australia is around $26,000, according to the Housing Industry Association of Australia. However, your bathroom renovation project can cost anywhere from $8, 000 for a small-budget renovation to over $35,000 for a premium transformation, depending on size, materials, and the extent of the work.

Below is a breakdown of the main costs involved in a bathroom renovation project, to help you plan and budget with confidence.

Demolition & Tile Removal (incl. Asbestos & Pest Risks)

Before the renovation, the existing bathroom must be stripped out, which includes tile removal and the disposal of old fittings. If asbestos or termite damage is discovered, costs can increase significantly.

Basic demolition: $500 – $1 500
Tile removal: $45 – $60 per square metre
Skip bin hire: $300 – $600
Asbestos removal: $35 – $50 per square metre

Plumbing costs

Plumbing typically accounts for 20–35% of the total project cost. Keeping the existing bathroom layout helps reduce expenses while moving plumbing for a premium layout increases labour and materials.

Licensed plumber: $100 – $150 per hour
Minor updates (such as tapware replacements): $800 – $1 500
Relocating plumbing for a vanity or shower: $3 000 – $7 000+
Toilet installation: $150 – $400 (excluding supply cost)

Waterproofing (AS3740 Compliance)

Waterproofing protects your home’s structural integrity and is legally required under AS3740 standards. For an average-sized bathroom, expect to pay between $500 and $900, depending on the size and complexity.

Rate range: $50–$100 per m²

Tiling (materials + labour)

Floor tiles and wall tiles form a major part of the total cost and add to the room’s visual appeal. Costs vary depending on whether you choose budget materials or higher quality products.

Cost of Bathroom Tiles (Supply Only)

Bathroom Size	Approx. Area (m²)	Budget Tiles	Premium Tiles
Small	15 m²	$525	$900
Medium	17 m²	$595	$1,020
Large	22 m²	$980	$1,680

These prices are based on an average tile cost of $30–$55 per square metre for budget options, and up to $75 per square metre or more for higher-end tiles.

Cost of Bathroom Tilers (Labour Only)

Bathroom Size	Approx. Area (m²)	Budget Labour	Premium Labour
Small	15 m²	$1,125	$1,800
Medium	17 m²	$1,275	$2,040
Large	22 m²	$2,100	$3,360

The major cost of tiling labour usually depends on:

The type and size of tiles (e.g. ceramic, porcelain, mosaic, large format or smaller tiles)
The difficulty of the layout and cuts required
Whether feature walls or patterned installations are involved

Total Estimated Tiling Costs (Tiles + Labour)

Bathroom Size	Budget Total	Premium Total
Small	~$1,650	~$2,700
Medium	~$1,870	~$3,060
Large	~$3,080	~$5,040

These totals combine supply and labour, giving a clear idea of how much tiling might cost in different-sized bathrooms.

Hidden Costs to Watch Out For

Waterproofing repairs: Old or damaged membranes can lead to extra labour and delays.
Structural issues: Rotten floors, termites or slab cracks may require urgent repair before installing new tiles
Delivery and waste removal: Costs for skip bins, debris removal and delivery of large items can quickly add up.
Extra permits: Major layout changes or strata work may require additional permits and incur extra call out fees from certifiers or consultants.
Mid-project design changes: Switching fixtures or layout after work begins adds time, labour and cost.

Common Bathroom Renovation Mistakes to Avoid

Small mistakes can lead to big problems during a renovation. Avoid these common pitfalls to keep your project smooth and cost-effective.

Not budgeting for contingencies: Set aside 10 to 15% of your total budget as a contingency budget for unforeseen events.
Buying fittings before measuring: Always measure your space before choosing vanities or fixtures.
Skipping ventilation: Poor airflow can cause mould and moisture damage over time.
Overcapitalising: Spending too much on high-end finishes in a lower-value home may not pay off.
Ignoring waterproofing compliance: Use a licensed waterproofer and always get certification for peace of mind.

How to Reduce the Cost of Bathroom Renovation

Renovating your bathroom doesn’t have to break the bank. With a little planning, smart product choices and a clear focus on priorities, you can reduce the total cost of your bathroom renovation without sacrificing quality, compliance or style.

To keep your renovation process cost-effective:

Keep your existing layout to avoid expensive plumbing and major structural changes.
Reuse what’s in good condition, like vanities or tiles, by resurfacing or regrouting.
Choose affordable materials such as ceramic or porcelain tiles over stone.
Buy fittings and fixtures yourself to save on contractor markups.
Use framed or semi-frameless shower screens instead of costly frameless ones.
Pick ready-made vanities rather than custom-built units.
Plan everything upfront and avoid changes mid-renovation to prevent extra costs.

How to Get an Accurate Bathroom Renovation Quote

Getting a detailed quote upfront helps you avoid hidden costs and plan your renovation with confidence. A proper quote should reflect the real scope of work, not just rough numbers.

To get the most accurate pricing:

1. Create a clear layout

Even a basic floor plan or sketch helps. It shows what’s being moved or updated and gives tradies a clear picture of plumbing, electrical and structural changes.

2. Define your renovation scope

Be specific about what work needs to be done, whether it’s a complete bathroom renovation, updating tiles and bathroom fittings, or changing the layout.

3. Choose your materials and fittings early

List the tiles, tapware, vanity, lighting and new bathroom accessories you want. Having these details upfront gives you more accurate pricing and better control over the look and cost.

4. Use a renovation cost calculator

Before getting quotes, use a cost calculator to estimate your approximate costs for bathroom renovation based on size, materials and layout. It sets a solid baseline.

5. Book a site visit

A proper inspection helps the renovator check access, plumbing, and any structural issues that could affect cost or timing. This avoids surprises and makes your quote more accurate.

6. Ask for an itemised, fixed-price quote

Get a quote that breaks down labour costs, materials, waterproofing, tiling, demolition and clean-up. Also, choose fixed-price quotes rather than hourly rates as it gives you more cost certainty.

7. Check what’s included (and what’s not)

See if things like permits, waterproofing, and strata approvals are covered. Also, confirm any exclusions, so there are no unexpected add-ons down the track.

8. Be upfront about your budget

Sharing your budget helps tradies tailor the quote to suit your needs and recommend options that fit without wasting time or overspending.
