Renovating your bathroom can be one of the most rewarding home improvement projects. A modern, functional bathroom not only makes daily routines more enjoyable but can also significantly increase the value of your home. However, one of the first questions homeowners ask is: “How much does a bathroom renovation cost?”
The answer isn’t straightforward, as costs can vary widely depending on the size of your bathroom, materials, fixtures, and the complexity of the renovation. In this guide, we’ll break down bathroom renovation costs in Australia, explore what influences these costs, and provide tips to help you save money while achieving your dream bathroom.
Average Bathroom Renovation Costs in Australia (2025)
Bathroom renovation costs in Australia have been rising steadily due to labour rates, material costs, and the growing demand for high-quality fixtures. On average:
- Budget renovations: $8,000 – $15,000
- Mid-range renovations: $15,000 – $30,000
- High-end renovations: $30,000 – $50,000+
These ranges include labor, materials, plumbing, electrical work, and fixtures. Your city or suburb can also affect pricing, with major cities like Sydney and Melbourne typically being more expensive than regional areas.
Factors That Affect Bathroom Renovation Costs
- Size of the Bathroom:The size of your bathroom is one of the most significant cost factors. A small powder room or ensuite will cost less than a large master bathroom with a bathtub, double vanity, and walk-in shower. Larger bathrooms require more materials, more labor hours, and potentially more plumbing or electrical work.
- Materials and Finishes:The choice of materials has a big impact on costs. Some common considerations include:
- Cabinetry: Laminate cabinets are budget-friendly, while custom timber cabinetry can be costly.
- Benchtops: Laminate is cheaper; stone, engineered quartz, or marble costs more.
- Tiles: Ceramic or porcelain tiles are affordable, while natural stone or large-format tiles are premium.
- Fixtures: Standard taps, showers, and toilets are less expensive than designer or water-saving models.
Tip: Mixing budget-friendly materials with a few high-end features can create a stylish look without breaking the bank.
- Plumbing and Electrical Work:If your renovation involves moving plumbing or electrical systems, costs can rise significantly. Adding a new shower, bathtub, or vanity requires careful planning and professional installation.
Tip: Retaining the current layout of your bathroom is a simple way to save thousands of dollars in plumbing and electrical work.
- Labor Costs:Labor is a significant part of bathroom renovation expenses. Hiring licensed plumbers, electricians, and tilers ensures quality work and compliance with Australian building standards. Labor costs can vary depending on your location, the complexity of the project, and the reputation of the tradespeople.
Typical Bathroom Renovation Costs by Project Type

High-end renovations are perfect for homeowners who want a luxurious, spa-like experience and are prepared to invest in long-lasting quality.
Tips to Save Money on a Bathroom Renovation
- Retain Your Existing Layout: Avoid moving plumbing or electrical lines unless necessary. Keeping the current setup can save thousands.
- Mix Materials Wisely: Use budget-friendly materials for large surfaces and splurge on key features like benchtops or vanity cabinets.
- DIY Where Possible: Simple tasks like painting, installing shelves, or adding accessories can be done yourself to reduce labor costs.
- Shop Smart for Fixtures: Look for sales, clearance items, or gently used fixtures to save money without compromising style or quality.
- Prioritise Functionality: Focus on improvements that make the bathroom more usable and efficient, such as storage, lighting, or ventilation, rather than purely aesthetic changes.
- Get Multiple Quotes: Comparing several contractors and tradespeople ensures competitive pricing and better value.
Planning Your Bathroom Renovation
- Set a realistic budget based on your needs and desired finishes.
- Determine which features are essential and which are optional.
- Obtain multiple quotes from licensed contractors.
- Factor in a contingency of 10–15% for unforeseen costs.
- Plan for timelines, especially if materials or fixtures have long lead times.
