How Much Does an Average Bathroom Renovation Cost?

Planning a bathroom renovation can be exciting, but before you start choosing tiles and fixtures, it’s important to understand what it’s likely to cost. Bathroom makeovers are among the most common home upgrades in Australia, yet they can quickly become one of the most expensive if not budgeted properly. Costs depend heavily on the size of your bathroom, the quality of materials you choose, and how much structural or plumbing work is involved. Having a realistic budget from the start helps you make smarter design decisions and prevents costly surprises once work begins.

Average Bathroom Renovation Cost in Australia

On average, Australian homeowners spend between $10,000 and $30,000 to renovate a standard bathroom. A basic renovation focused on cosmetic changes — like replacing taps, repainting, or swapping out fittings — might sit around $10,000 to $15,000. A mid-range renovation, which usually includes new tiles, vanities, and upgraded fixtures, often ranges from $15,000 to $25,000. If you’re after a high-end designer bathroom with custom finishes, luxury fittings, or layout changes, expect costs to exceed $25,000 to $40,000 or more.
These figures serve as a general guide; every project is unique, and your final cost will depend on materials, tradie rates, and the complexity of the design.

Key Cost Factors

Several factors can significantly influence how much you’ll spend on your bathroom renovation. Bathroom size plays a major role — a small ensuite costs less to update than a large family bathroom. Layout changes that involve moving plumbing or electrical points will also increase costs because they require licensed trades. The choice of materials—from tiles and vanities to tapware and shower screens—can make a huge difference, with premium products often doubling your spend.
Other cost drivers include labour, which typically accounts for 40–60% of the total budget, and compliance requirements like waterproofing and permits. In short, even two bathrooms of the same size can vary in cost based on design choices and how much professional help is needed.

Cost Breakdown by Category

To help you visualise where the money goes, here’s a general breakdown of common renovation expenses. Demolition and waste removal typically cost between $1,000 and $2,500, depending on how extensive the strip-out is. Plumbing and electrical work—often the biggest expense—can range from $1,500 to $4,000. Tiling and waterproofing generally make up another $2,000 to $6,000, depending on the size of the room and tile selection. Fixtures and fittings, such as toilets, showers, and vanities, can add $2,000 to $6,000, while painting and finishing touches usually sit around $500 to $1,000.
Altogether, these elements build the total cost, and knowing how each component contributes allows you to prioritise what matters most — functionality, style, or long-term durability.

Hiring Professionals vs DIY

When it comes to bathroom renovations, knowing when to bring in professionals can make all the difference between a smooth project and an expensive mistake. While small tasks like painting, changing cabinet handles, or updating mirrors are DIY-friendly, major work such as plumbing, waterproofing, and electrical installations must legally be done by licensed tradies in Australia. Attempting these jobs yourself not only risks safety issues but can also void insurance or fail council inspections.
Hiring experienced professionals ensures your renovation meets Australian building standards and avoids costly rework later. Most homeowners find that paying for quality workmanship upfront delivers better long-term value — fewer leaks, cleaner finishes, and a bathroom that stands the test of time.

Ways to Reduce Bathroom Renovation Costs

A beautiful new bathroom doesn’t have to break the bank. The key is smart planning and prioritising where your money goes. Start by keeping the existing plumbing layout wherever possible, as moving pipes or drains is one of the biggest expenses. Next, choose mid-range materials — there are plenty of stylish yet affordable tiles, vanities, and fixtures that offer the same modern look as designer brands.
Mix and match surfaces, such as using feature tiles on one wall instead of all four, or repainting existing cabinetry for a fresh update. Finally, always get multiple quotes from verified tradies on The Tradie List. Comparing at least three estimates can help you find fair pricing without sacrificing quality. Setting aside a 10–15% contingency budget is also wise, as small surprises often appear once work begins.

Average Bathroom Renovation Cost by City

Renovation costs can vary significantly depending on where you live in Australia, largely due to local labour rates and material prices.

• In Sydney, bathroom renovations tend to be the most expensive, averaging between $18,000 and $30,000, thanks to higher labour and compliance costs.

• Melbourne homeowners usually spend between $17,000 and $28,000, with mid-range finishes being the most popular.

• In Brisbane, Adelaide, and Perth, prices are slightly lower, typically between $12,000 and $25,000, depending on bathroom size and material quality.

• Regional areas may see lower labour costs, but transport and material availability can balance out savings.

No matter where you’re located, getting quotes from local licensed tradies ensures accurate pricing for your specific area and project scope.

Bathroom Renovation Cost Checklist

Before you start tearing out tiles or ordering fixtures, it helps to have a clear checklist to keep your project on track and within budget. Here’s a quick guide to what you should prepare and consider before booking tradies:

• Set your total budget — include a 10–15% buffer for unexpected expenses.

• Plan your design and layout — decide whether plumbing or walls will move.

• Gather multiple quotes from licensed plumbers, electricians, and tilers.

• Confirm permits and compliance — especially for waterproofing or structural changes.

• Choose fixtures and materials early to avoid delays or stock shortages.

• Schedule trades efficiently — demolition, rough-in, waterproofing, tiling, and finishing.

• Inspect and sign off each stage before making final payments.

Using a checklist like this helps streamline your renovation, ensures accountability, and keeps costs transparent from start to finish.
