How Much Does a Small Bathroom Renovation Cost in Australia?

Renovating a bathroom is exciting, until you start crunching the numbers. So, how much does a small bathroom renovation cost in Australia?

Whether you’re updating an ensuite or transforming an old bathroom design, understanding the cost breakdown can help you in planning your bathroom renovation with confidence. In this guide, we’ll explore everything from average prices to budgeting tips, all tailored to Australian homes.

What Counts As a “Small” Bathroom Renovation?

Before diving into numbers, let’s clarify what we mean by a “small” bathroom. Not all new bathroom renovation projects are created equal, and your renovation scope plays a big role in pricing.

What Qualifies As a Small Bathroom?

In most Australian homes, a small bathroom is typically under 6 square metres. These spaces often include:

• A toilet
• A shower or a small bathtub
• A vanity or sink unit

You’ll commonly find these layouts in apartments, second luxury bathrooms, powder rooms, or compact ensuites. While small in size the bathrooms still require all the essential fixtures, and that’s where significant costs can add up.

Full vs. Partial Renovation

Not all renovations require a full overhaul. Here’s a quick breakdown:

• Full renovation:Involves stripping everything back to bare bones, retiling, replacing all fixtures, and possibly altering the layout.
• Partial renovation: Focuses on cosmetic upgrades like repainting, changing tapware, or resurfacing tiles.

Naturally, a full renovation demands a bigger budget due to added labour, bathroom materials and fittings, and potential plumbing changes.

What Affects the Cost of a Small Bathroom Renovation?

Why do some bathroom renovations cost $10,000 while others cost $ 30,000 and above? It comes down to several factors.

1. Fixtures and Material Choices

The quality of your materials can cause big price swings:

• Tiles:Basic ceramic starts at $30 per square meter, while natural stone tiles can exceed $100 per square meter.
• Vanities: Flat-pack options are budget-friendly, while custom cabinetry costs more.
• Tapware: Expect a $100 mixer tap at the low end, or $700+ for designer options.

1. Labour and Contractor Rates

Licensed plumbers, tilers, and electricians are essential, and their rates vary by region. For example, tradies in Sydney may charge more per hour than those in regional NSW.

Hiring a reputable team might cost more upfront, but it can save you thousands by avoiding costly mistakes.

1. Changes to Layout or Plumbing

Moving a toilet or shower? That’s one of the most expensive changes you can make. Plumbing relocation not only adds labour but may require council approval, waterproofing updates, and inspections.

How to Renovate a Small Bathroom on a Budget

Renovating your dream bathroom doesn’t have to break the bank. With a few simple decisions, you can keep bathroom renovation costs down while still achieving a stylish result. The key is to prioritise what matters most, find cost-effective materials, and keep the renovation process as efficient as possible.

Prioritise Key Features

Focus first on the essential elements that impact safety and performance. These areas should always come before cosmetic enhancements:

• Waterproofing: This is non-negotiable. Poor waterproofing can lead to serious water damage, mould, and expensive repairs down the track.
• Ventilation: Proper airflow helps prevent moisture build-up and extends the life of your finishes.
• Functional Layout: Make sure the layout works for your daily routine. A good layout can improve both comfort and storage in small spaces.

It’s easy to get caught up in aesthetics, but skipping these fundamentals can result in higher costs later. Always address the foundation before the finishes.

Choose Affordable Materials That Look Great

You don’t need designer tiles or marble vanities to get a stylish finish. Plenty of affordable materials look fantastic and hold up well over time:

• Subway Tiles:Classic, versatile, and widely available. They offer a clean look and can be styled in various patterns for visual interest.
• Prefabricated Vanities:These off-the-shelf options can save you hundreds compared to custom cabinetry, without compromising on appearance.

Mix and match budget-friendly materials with one or two statement pieces if you want to elevate the space while keeping costs low.

Tips to Keep Labour Costs Down

Labour is often one of the biggest expenses in any renovation. Here’s how to minimise it:

1. Prep the Space Yourself:Clearing out the bathroom, removing old fittings, and cleaning the area before your tradespeople arrive can save billable hours.
2. Stick to the Existing Layout: Changing the position of the toilet, sink, or shower usually means moving plumbing, and that means a higher cost to renovate a bathroom. Keeping the layout as-is will drastically cut labour and material expenses.
3. Bundle Tasks Efficiently: Try to schedule similar tasks (like plumbing or tiling) back-to-back to minimise the number of call-outs and reduce downtime between trades.
4. Stick to the Plan: Last-minute changes can quickly increase labour costs and delay your timeline. Lock in your decisions early and keep communication clear to avoid extra work.

Small decisions during planning can lead to big savings once work begins. Always communicate clearly with your contractors and get quotes upfront to avoid unexpected charges.

Timeline and Disruption: What to Expect During the Renovation

Understanding how long a bathroom renovation takes helps you plan around the disruption more effectively. Even small renovated bathroom projects can feel disruptive, especially in homes with limited facilities. That’s why having a clear timeline and backup plan can make the process smoother and less stressful.

How Long Does a Small Bathroom Renovation Take?

On average, a small bathroom renovation in Australia takes 2 to 4 weeks to complete. However, several factors can affect this timeline:

• Drying Times: Winter can slow down drying time for waterproofing, adhesives, and paint, adding an extra 3 to 5 days to your schedule.
• Project Complexity:A cosmetic makeover is quicker than a full gut and remodel involving plumbing or electrical upgrades.
• Contractor Availability:Tradies often juggle multiple jobs, so availability can delay progress if not scheduled properly.
• Delivery of Materials:Waiting on tiles, vanities, or fixtures, especially custom or imported items, can push out your timeline.

Proper planning and clear communication with your contractor can help avoid delays and keep your project moving efficiently.

What to Expect Day-by-Day

While every renovation is unique, most follow a similar sequence. Here’s a week-by-week snapshot of what typically happens:

• Week 1: Demolition and Rough-In

This stage involves removing old fittings, tiles, and cabinetry. Once cleared, plumbers and electricians install or adjust the infrastructure to suit the new layout.

• Week 2: Waterproofing and Inspections

After the rough-in, the space is waterproofed to Australian standards. This step may include inspections, especially if you’re in a strata-managed building or making significant changes.

• Week 3: Tiling and Painting

Once waterproofing is complete and dry, tilers come in to install floor and wall tiles. Painting and other finishes often follow shortly after.

• Week 4: Fixture Installation and Final Touch-Ups

Your toilet, vanity, shower screen, and lighting are installed. The space is cleaned, any final tweaks are completed, and the family bathroom is ready for use.

Note: Some projects wrap up faster, especially if the layout is simple and materials are on hand. Others may stretch beyond four weeks due to surprises or availability issues.

Living in the House During the Project

If your home only has one bathroom, renovations can be especially challenging. Here are a few ways to cope:

• Arrange Access to Another Bathroom:If possible, coordinate with a neighbour, friend, or family member. Alternatively, consider short-term access to facilities at a gym or community centre.
• Use Temporary Setups:Portable smaller bathroom setups, outdoor showers, or hiring a temporary ensuite service can be helpful for short-term disruptions.
• Plan Shower and Toilet Access Wisely: Work with your contractor to understand when plumbing will be functional. You may be able to schedule around these windows.

The key is preparation. Speak with your builder early, plan, and make sure everyone in your household understands the schedule and any temporary arrangements.

Mistakes That Can Blow Out Your Renovation Budget

Avoiding a few key pitfalls can keep your overall costs on track.

1. Common Budgeting Pitfalls: Not leaving a contingency (add at least 10% to your budget). Ignoring hidden issues like water damage or outdated plumbing
2. Last-Minute Design Changes: Changing your mind mid-project? That’s when labour hours spike and the cost of a bathroom renovation may follow.
3. Choosing the Cheapest Quote Blindly: Instead, make sure to check licenses, read reviews, and ask for a detailed quote breakdown.
4. Rushing Waterproofing or Cheaping Out on Essentials: These shortcuts often lead to water leaks, mold, or could cost repairs down the track.

Should You Hire a Bathroom Designer or Manage the Project Yourself?

Some homeowners try to cut total costs by managing the project themselves. It can work if you know what you’re doing.

Pros of Working With a Bathroom Designer

• Access to trade discounts and suppliers
• Streamlined planning and timelines
• Visual 3D mock-ups for design confidence

When DIY Project Management Is Possible

• For small, cosmetic changes
• If you’re experienced with trades or renovations
• When you’re not making layout or plumbing changes

It’s also worth exploring how much a bathroom designer costs before deciding which approach suits your renovation goals.
