Bathroom Renovation Costs in Australia: A Full Breakdown for 2025

There’s something about stepping into a freshly renovated bathroom that just feels right. Maybe it’s the gentle warmth of underfloor heating beneath your feet on a winter morning, or the quiet elegance of porcelain tiles that shimmer just so in the afternoon light, transforming your space into a new bathroom sanctuary. In 2025, more Australian homeowners are rediscovering the bathroom as a sanctuary—a place that blends beauty with function and brings a little more comfort to the everyday.

But before you start pinning your dream bathroom or collecting samples of wall tiles and tapware, there’s one big question to answer: how much does a bathroom renovation actually cost?

Introduction to Bathroom Renovations

Embarking on a bathroom renovation can feel like a daunting task, but with the right planning and execution, it can transform into a highly rewarding experience. According to the Housing Industry Association, the average bathroom renovation cost in Australia hovers around $26,000. This figure, however, can vary significantly based on factors such as the size of the bathroom, the materials chosen, and the labour costs involved.

In this guide, we’ll delve into the various aspects of bathroom renovations, from planning and design to selecting fixtures and fittings, and navigating permits and permissions. Whether you’re aiming for a budget-friendly update or a luxurious overhaul, understanding these elements will help you create a space that’s both functional and beautiful.

What Australians Are Spending in 2025

According to the latest figures, the average bathroom renovation cost in Australia is now around $26,747. That number might raise some eyebrows, but it reflects the rise in material and labour costs and a growing appetite for personalisation. Think heated towel rails, smart toilets, and custom cabinetry—not to mention the rising cost per square metre for even the most basic fixtures and fittings, which are among the major costs in a bathroom renovation.

Your Bathroom Budget: What to Expect

Bathroom renovations generally fall into three price brackets:

• Basic bathroom renovation (budget cost): $5,000 to $15,000
• Mid-range: $15,000 to $40,000
• Luxury bathroom renovation: $35,000 and up

The average spend for an average sized bathroom lands somewhere in the middle bracket. If you’re dreaming of a premium bathroom renovation, expect the total cost to reflect high-end finishes, major structural changes, and possibly a complete overhaul of your plumbing layout.

Planning and Design

The foundation of any successful bathroom renovation lies in meticulous planning and thoughtful design. Start by considering the size and layout of your bathroom. Are you working with a small bathroom or a more spacious area? The room size will influence your choices in fixtures, fittings, and overall design.

Next, think about the materials and fixtures you want to use. Are you drawn to the sleek look of porcelain tiles or the warmth of natural timber? Your choices here will significantly impact both the aesthetic and the bathroom renovation cost. Don’t forget to factor in labour costs, which can make up a substantial portion of your budget.

It’s also wise to set aside a contingency fund for unexpected costs. Water damage, electrical upgrades, or unforeseen structural work can quickly add up. Researching and selecting the right tradespeople and suppliers is crucial. A reliable team can ensure your renovation stays on track and within budget, turning your vision into reality.

Where the Money Goes: A Practical Breakdown

Here’s a real-life look at what you’ll be paying for:

• Plumbing costs: Call-out fees range from $60 to $100, with hourly rates from $100 to $150. If you’re moving pipes, costs rise quickly.
• Floor and wall tiling: Tiling costs vary from $20 to $150 per square metre. Labour adds another $35 to $120 per square metre rate.
• Vanities: A basic unit might cost $120, while designer vanities with custom cabinetry can exceed $1,500.
• Toilet cost: From $275 for a standard model to $1,200+ for high-end smart toilets.
• Shower screens: Expect to pay $400 to $600 for framed and up to $1,000+ for frameless shower screens.
• Underfloor heating: This luxury touch runs $30 to $120 per square metre.
• Bathroom lighting: Budget around $200 to $1,000 depending on style and placement.

Factor in labour costs, which typically make up 20–30% of your renovation budget, and you can see how it all adds up.

Fixtures and Fittings

When it comes to bathroom renovations, the fixtures and fittings you choose can make a world of difference. These elements not only define the look and feel of your bathroom but also play a crucial role in its functionality. From toilets and sinks to shower screens and bathtubs, the options are vast.

For instance, a basic toilet might set you back around $120, while a high-end smart toilet can cost upwards of $1,200. Similarly, shower screens range from $400 for a standard model to over $600 for a frameless design. Lighting fixtures are another essential consideration, with prices varying based on style and placement.

Balancing your budget with your desired style is key. Opt for a mix of budget-friendly items and a few standout features to create a space that feels both luxurious and practical. Remember, the right fixtures and fittings can elevate your bathroom from ordinary to extraordinary.

Warmth, Texture, and Everyday Luxury

Renovating bathrooms is more than ticking boxes. It’s about how the space feels. There’s something to be said for the pleasure of stepping out of the shower and wrapping yourself in a towel warmed by a sleek heated towel rail, or the quiet hum of a well-lit vanity while you get ready in the morning.

For some, it’s the joy of clean, matte black fixtures against cool concrete tones. For others, it’s the calm of natural timber and creamy stone that softens the harsh edges of the day. A bathroom reno is a rare chance to create a pocket of peace that’s entirely yours.

Planning for Unexpected Costs

Every bathroom renovation project comes with a few surprises, and key factors like water damage, electrical upgrades, or structural work can quickly add up. That’s why interior designers and seasoned renovators always suggest setting aside 10–20% of your renovation budget for unexpected costs.

And if your home is in a strata property, don’t forget to get committee approval before making any major structural changes. Most councils will also require permits for a complete bathroom renovation, especially if it includes plumbing or layout changes.

Permits and Permissions

Before you dive into your bathroom renovation, it’s crucial to secure the necessary permits and permissions. This step is often overlooked but is essential to ensure your project complies with local regulations. Depending on the scope of your renovation and your location, you may need permits from your local council.

If you live in a strata-titled property, you’ll also need approval from your strata committee. The costs for these permits can vary depending on the extent of the work and the specific requirements of your area. Ensuring compliance with building codes and regulations, particularly those related to waterproofing, electrical work, and plumbing, is vital.

Skipping this step can lead to fines, penalties, and even the need to redo the work, which can significantly increase your bathroom renovation costs. So, take the time to get the necessary approvals and ensure your renovation is smooth and hassle-free.

By following these guidelines and considering all aspects of your bathroom renovation, you can create a space that not only meets your needs but also adds value and comfort to your home. Happy renovating!

Who You Hire Matters

Renovating bathrooms isn’t a solo project. A successful bathroom renovation relies on licensed contractors—and the right ones can make a world of difference. Ask for itemised quotes, check licences, and get referrals. Having a good tiler, plumber, or interior designer on board turns what could be a stressful process into a smooth, even enjoyable experience, especially for tasks like toilet installations.

Smart Ways to Save

Even if you’re dreaming big, there are ways to keep costs in check:

• Stick to the existing floor plan
• Choose mid-range over premium bathroom fixtures
• Mix budget materials with a few standout features (hello, beautiful shower head)
• Shop during sales or in clearance sections
• Keep structural work to a minimum

It’s possible to achieve a budget bathroom renovation that still feels thoughtful, warm, and well-designed, making budget renovations a viable option for many homeowners.

A Note on Timeframes

A full renovation takes around 3–4 weeks of actual build time, with planning stretching anywhere from one to six months depending on the scope. The process usually includes demolition, rough-ins, waterproofing, tiling, and final fit-off. Allow extra time for materials, especially if you’re choosing bespoke or imported items.

In the End, It’s About How It Feels

At the heart of every renovation is a story: of a young family turning a tired bathroom into a functional space for busy mornings; of a couple creating their first grown-up ensuite with a skylight and terrazzo tiles; of a retiree finally giving their old bathroom the upgrade it deserves.

So yes, bathroom renovation costs are real, and yes, they can be daunting, but understanding the overall cost is crucial for making informed decisions. But they’re also an investment in how your home lives and breathes.

And when the dust settles and the last tile is polished, what you’re left with is a space that serves you daily—a space that feels just right.
