How Much Does a Bathroom Renovation Cost in Sydney in 2024?

Thinking about a bathroom renovation? It’s exciting, but figuring out the costs can be tricky. Whether you want a spa-like retreat or just a fresh look, knowing the expenses is key.

Here’s a guide to help you understand what goes into the cost of bathroom renovations in Sydney so you can plan your budget wisely.

Types of Bathroom Renovations

When renovating your bathroom in Sydney, you usually have three options: complete renovations, remodelling, and makeovers. Each option has its benefits and things to consider.

Complete Bathroom Renovations

This involves a full overhaul, including changes to the layout, and updates to electrical, plumbing, and flooring. It’s more expensive and takes longer, but you get a fully transformed, custom bathroom. Some bathroom renovation specialists, like Swish Plumbing, even offer a 7 year warranty on all full bathroom renovations.

Bathroom Remodelling 

Remodelling focuses on updating the existing plumbing features, like the toilet, bathtub, and overall look, without major structural changes. It’s quicker and cheaper, with updates like painting, re-tiling, and installing new fixtures in the same positions.

Bathroom Makeovers 

A makeover is budget-friendly and focuses on improving the look without structural changes. This might involve painting, resurfacing tiles, replacing mirrors, and adding new fixtures in the existing layout. It’s popular for those wanting to spruce up their bathroom before selling their home. 

Average Bathroom Renovation Costs in Sydney

Several factors affect the cost of a bathroom renovation in Sydney. Knowing these can help you set a realistic budget.

Standard Bathroom Renovation Costs 

For a standard renovation, expect to pay between $20,000 and $30,000. This covers new taps, vanity, basin, shower screen, mirrors, and bathroom door screens, as well as replacing lighting, ventilation, toilets, and bathtubs. It includes labour costs but not the fixtures or tiles, which can add to the budget.

Luxury Renovation Costs 

A luxury renovation can exceed $35,000. This includes professional design services, moving walls, and redesigning the floor plan. High-end items like freestanding bathtubs, custom vanities, premium tiles, and advanced lighting and heating features can add to the cost.

Factors Affecting Bathroom Renovation Costs

Several factors can influence the overall cost of your bathroom renovation:

Bathroom Size and Area 

The size of your bathroom affects the cost. Larger bathrooms need more materials and labour, increasing expenses. The scope of work, like demolition and rebuilding, also impacts the cost per square metre.

Labour Costs 

Labour is a significant part of renovation costs. Charges vary based on work complexity, trades involved (e.g., plumbing, tiling, electrical), and expertise needed. Tasks like moving fixtures, structural changes such as removing walls as well as choice of tiles patterns or style such as herringbone or subway will add to labour costs.

Materials and Fixtures 

The choice of materials and fixtures greatly affects the budget. Costs for tiles, flooring, vanities, basins, and fittings range from budget-friendly to high-end. Balancing quality, brand, and customisation helps manage costs. At Swish Plumbing, we work with the best bathroom suppliers and can assist you in choosing the best options for your style and budget.


Waterproofing is critical to prevent leaks and mould. Costs vary depending on bathroom size, depth, layout, and waterproofing method used.

Design and Planning Costs 

Hiring a professional designer adds value by maximising space, creating functional layouts, and achieving your desired look. Though it adds to the cost, it ensures a well-executed, appealing bathroom.

Location and Market Conditions 

Where you live affects renovation costs. Labour rates and material prices vary across suburbs and regions, while your property type (unit vs house), and access to your property will also affect the price of your bathroom renovation project. Finally, mMarket conditions like supply chain issues or material cost changes also impact the budget.

Unexpected Costs and Considerations

When planning a bathroom renovation, it’s important to be prepared for potential hidden costs or challenges that can come up:

Structural Issues 

Common hidden costs include unexpected structural problems like cracked pipes or water damage. These issues may need extensive repairs or replacements, adding to your budget.

Asbestos and Hazardous Materials 

Older homes may have hazardous materials like asbestos. Safe removal and disposal can be costly and time-consuming, requiring specialised contractors.

Electrical and Plumbing Upgrades 

Older homes may need extensive electrical or plumbing work to meet current safety standards. This includes rewiring, replacing pipes, or reconfiguring layouts for new fixtures.

Customisation and Upgrades 

Personalising your bathroom with high-end finishes or custom designs can increase costs. While these upgrades create a unique space, weigh the benefits against the financial impact.

Permits and Regulatory Compliance 

Depending on the renovation scope, you may need permits and must comply with local building codes. Fees and inspection costs add to the budget.

To handle unexpected costs, allocate a contingency budget of about 20% of the total renovation cost. This helps cover unforeseen expenses and ensures a smoother renovation experience.

Maximising the Value of Your Bathroom Renovation

While bathroom renovations can be expensive, they are an investment in your home’s value and your living experience. Some 

Increased Home Value 

A well-designed bathroom renovation can increase your home’s value by up to 75% of the renovation cost. This makes it one of the most valuable home improvements, offering a strong return on investment.

Improved Quality of Life 

A beautifully renovated bathroom enhances your daily living experience, providing a relaxing and luxurious space for rejuvenation and well-being.

Long-term Durability and Efficiency 

Investing in quality renovations ensures long-term durability and efficiency, saving you from future repair and maintenance costs.

Budgeting and Financing Options

Planning a bathroom renovation in Sydney requires careful budgeting and consideration of your finances. Assess your budget, explore financing options, and allocate funds wisely for a successful, stress-free project.

Assessing Your Budget 

Evaluate your finances and set a comfortable budget aligned with your renovation goals. Consider savings, home equity, and additional funds. Set aside a contingency budget for unexpected expenses.

Financing Options 

If personal funds are insufficient, consider financing options like home equity loans, personal loans, or renovation financing programmes. Research terms, interest rates, and repayment schedules to find the best fit.
