How Much Does an Average Bathroom Renovation Cost?

Bathroom renovations are one of the most popular upgrades for Australian homes. Whether it’s modernising an outdated space, creating a luxurious retreat, or adding value before selling, a bathroom renovation is often at the top of a homeowner’s wish list.

But how much does it actually cost to renovate a bathroom? The answer depends on the size of the bathroom, the quality of finishes, and the complexity of the work involved. On average, costs can range from a few thousand dollars for a budget-friendly makeover to tens of thousands for a full luxury transformation.

In this guide, we’ll explore the factors that influence bathroom renovation costs, give you average price ranges in Australia, and provide tips for saving money while achieving the bathroom you want.

What Factors Affect Bathroom Renovation Costs?

There are several key factors that determine how much your bathroom renovation will cost:

Size of the bathroom: Larger bathrooms cost more to renovate simply because they require more tiles, fittings, and labour. A compact ensuite will always be cheaper than a spacious master bathroom.

Level of finish: The quality of materials and fittings has a huge impact on cost. Basic renovations use standard vanities, tiles, and tapware, while high-end projects feature designer fittings, premium stone tiles, and custom cabinetry.

Plumbing and electrical work: Keeping your layout the same will save money, while moving showers, baths, or toilets adds extra plumbing costs. Similarly, new lighting, underfloor heating, or heated towel rails will increase electrical expenses.

Waterproofing and tiling: These are some of the most labour-intensive aspects of a renovation. More tiling — especially with small or mosaic tiles — requires extra time and skill, which raises costs.

Labour rates and location: Where you live affects the price. Renovations in metropolitan areas generally cost more than in regional locations due to higher trade rates.

Structural or compliance issues: Older homes may reveal hidden problems, such as rotten timbers, poor ventilation, or even asbestos, all of which add to the budget. Waterproofing also needs to meet Australian standards and must be completed by a licensed professional.

Design complexity: Simple bathroom designs are quicker and cheaper to complete. Custom layouts, feature walls, or luxury additions like freestanding baths or walk-in showers require more time and skill, which raises the final bill.

Average Bathroom Renovation Costs in Australia

Bathroom renovation costs vary widely depending on the size of the room, the finishes you choose, and the complexity of the work. Here’s a general guide to what you can expect:

• Budget bathroom renovation: From $5,000 – $15,000. This typically covers small bathrooms or simple updates using standard fittings, tiles, and fixtures, with minimal changes to plumbing or layout.

• Mid-range bathroom renovation: Between $15,000 – $30,000. This is the most common range and includes higher-quality finishes, new vanities, shower screens, tiling, and some layout changes.

• Luxury bathroom renovation: $30,000 – $50,000+. At this level, you’re looking at premium tiles, designer fittings, underfloor heating, custom cabinetry, frameless shower screens, and possibly structural changes.

Small bathrooms like ensuites tend to be cheaper, while larger spaces such as master bathrooms cost more simply due to the greater amount of tiling, waterproofing, and fittings required.

Bathroom Renovation Cost Breakdown by Project Type

Breaking down the costs by project type helps you see where most of your money will go:

• Demolition and preparation: $1,000 – $3,000. Includes stripping out old tiles, fixtures, and fittings, plus waste disposal.

• Plumbing: $2,000 – $5,000. Moving or adding water outlets and drainage is one of the most expensive parts, especially if you change the bathroom layout.

• Electrical: $800 – $2,000. Covers new lighting, power points, exhaust fans, or heated towel rails. More complex systems like underfloor heating will cost more.

• Waterproofing: $1,000 – $2,000. Essential for protecting your home from leaks and required by Australian standards.

• Tiling: $5,000 – $15,000 depending on the size of the bathroom, tile type, and whether full-height tiling is chosen. Mosaic and stone tiles are more expensive to lay.

• Fixtures and fittings: $3,000 – $10,000. Includes vanity, toilet, bath, shower screen, and tapware. The cost depends on whether you choose standard or designer items.

• Cabinetry and storage: $1,500 – $5,000 for vanities, shelving, or custom joinery.

• Painting and finishes: $500 – $2,000. Final touches to walls and ceilings.

• Labour: Typically 40% – 60% of the total renovation cost, covering all trades required to complete the job.

Hidden or Additional Costs

Bathroom renovations often come with expenses that aren’t immediately obvious. For older homes, asbestos removal can significantly increase costs if it’s found behind walls or under flooring. Unexpected plumbing or electrical issues can also add to the budget, especially if pipes or wiring need to be replaced to meet modern standards.

Other hidden costs include waterproofing certification, which is mandatory in Australia, as well as council permits for structural changes. Don’t forget to budget for waste removal and disposal fees after demolition, as these are often billed separately. Even small items such as mirrors, towel rails, and accessories can add up quickly if not included in your initial plan.

Benefits of Renovating a Bathroom

A bathroom renovation is one of the most rewarding home improvements you can undertake. From a lifestyle perspective, it creates a space that is more functional, comfortable, and visually appealing. Modern designs often include better storage, improved lighting, and water-efficient fixtures that make everyday use easier and more enjoyable.

Financially, a renovated bathroom can add significant value to your property, making it one of the best investments for resale. Buyers are more attracted to homes with updated bathrooms, as they won’t need to take on the expense themselves.

Renovations can also improve energy and water efficiency with low-flow taps, dual-flush toilets, and efficient hot water systems — reducing ongoing household costs. Finally, a new bathroom ensures compliance with current waterproofing and safety standards, giving peace of mind that your home is protected from leaks and damage.

How to Save on Bathroom Renovation Costs

Bathroom renovations don’t have to break the bank if you plan carefully. One of the most effective ways to save is to keep the existing layout. Moving plumbing points for baths, showers, and toilets is one of the most expensive parts of a renovation, so leaving them in place can cut thousands off your budget.

Choosing mid-range fittings and tiles instead of premium designer brands can also help you save without compromising style. For tiling, consider using large-format tiles, which are quicker to lay and reduce labour costs compared to small mosaics.

Another way to cut costs is by handling some of the cosmetic work yourself, such as painting or installing mirrors and accessories. And as with any major project, always compare multiple quotes from local tradies to ensure you’re getting the best value for the work required.

Finding the Right Bathroom Renovation Specialist

Bathroom renovations require the skills of multiple trades — plumbers, electricians, tilers, and waterproofers. Choosing the right renovation specialist helps ensure that everything is coordinated properly, meets Australian standards, and is completed on time and within budget.

When selecting a bathroom renovator, consider the following:

• Licensing and insurance: Make sure your renovator and trades are licensed for plumbing, waterproofing, and electrical work, and carry the appropriate insurance.

• Experience and portfolio: Ask to see examples of previous bathroom projects to ensure their style and workmanship match your expectations.

• Detailed quotes: Request itemised quotes that cover demolition, plumbing, electrical, waterproofing, tiling, and fittings so you can compare accurately.

• Warranties and guarantees: A professional should stand behind their work with warranties on both labour and materials.

• Communication: Bathroom renovations can take several weeks, so working with a responsive, reliable specialist is key to a smooth project.
