How much does a bathroom renovation cost in Sydney in 2025?

Planning a bathroom renovation is exciting but the big question on everyone’s mind is often, “How much will it cost?” Renovating your bathroom can increase your home’s value and create a more comfortable space but understanding the costs involved can feel overwhelming for a homeowner. With so many factors affecting the price, knowing what to budget for can be challenging. In this guide, we’ll walk you through the average costs of bathroom renovations in Sydney, break down the main factors that influence prices, and offer tips for managing your budget. Whether you’re considering a simple refresh or a complete remodel, this post will help you understand what to expect and how to make informed decisions for your project.

What is the Average Cost of a Bathroom Renovation in Sydney?

When it comes to renovating a bathroom, costs can vary widely depending on your vision and the choices you make along the way. The average cost of a bathroom renovation in Sydney typically falls between $15,000 to $30,000. For a basic makeover, you might be looking at around $10,000 to $15,000. This is the usual price range for small bathrooms or a simple refresh with standard materials and minimal layout changes. Mid-range renovations consist of a more comprehensive update using mid-range materials and upgraded features, with possible minor layout adjustments and typically fall between $15,000 to $30,000. The price of high-end renovations starts at around $30,000 and this covers larger spaces, custom design, and high-quality materials and may include extensive changes to the layout.

Every bathroom is unique so the final cost will depend on factors like the size of your bathroom, the quality of materials and fixtures you choose, and any structural or plumbing changes needed.

What Factors Influence the Cost of Bathroom Renovations?

The cost of a bathroom renovation isn’t a one-size-fits-all. Several factors come into play with each impacting the final price differently. Here are the key elements that can influence the cost of your project:

large bathrooms tend to have more expenses

Size and Layout of the Bathroom

The size of your bathroom directly affects both material and labour costs. Larger bathrooms require more materials and take longer to renovate, which naturally increases the costs. If you will also need to change your layout, particularly with plumbing or removing internal walls, expect an increase in labour since these changes require professional knowledge and can be time-consuming. 

Quality of Materials and Fixtures

The materials you choose also play a huge role in the final renovation costs. Standard options like ceramic tiles are more affordable than premium options like natural stone tiles. Additionally choosing custom vanities, high-end bathtubs, or designer fixtures will drive the costs higher compared to more budget-friendly options.

Complexity of the Design

A straightforward and simple design is generally more affordable, while custom features, intricate tiling, and built-in storage can add complexity and cost. Unique layouts or custom work often require more skilled labour which comes at a premium rate.

Labour costs in Sydney

Labour costs in Sydney can vary but generally tend to be higher than in some other regions due to demand and cost of living. Hiring licensed tradespeople like plumbers, electricians, and tilers will ensure quality but can make up a significant portion of the budget. On average, you can expect around $50-$90 per hour for basic trades while specialised services will cost more.

Permits and Compliance with Local Regulations

Extensive renovations may require council approval if you’re making structural changes or altering plumbing significantly. This can add to the upfront cost as applications and inspections involve fees. It’s important that you check local regulations to understand what approvals are necessary before starting your bathroom renovation project. To get a clear understanding of what approvals you might need, refer to the NSW Fair Trading guidelines.

How Does Retaining or Changing the Bathroom Layout Affect Costs?

One of the biggest decisions in a bathroom renovation is whether to keep the existing layout or go for a fresh configuration. Layout changes can bring a new level of functionality to your space but they will come with added costs.

If you’re happy with your bathroom’s current setup and don’t need to move fixtures like the toilet, shower, or sink, you’ll find it cheaper to renovate your bathroom. Retaining your layout allows you to avoid relocating plumbing and electrical systems which are some of the most expensive aspects of a renovation. By keeping the same footprint, you’ll also reduce the time and labour involved which helps keep your budget in check. 

reconfiguring the bathroom entails more costs

However, if you’re looking to reconfigure your bathroom layout to improve flow, add more storage, or change the positioning of key features, costs can significantly increase. Moving a toilet or shower for instance requires extensive plumbing work, while relocating lighting or electrical outlets will need a licensed electrician. For some, there might be a need for structural changes such as moving walls to accommodate new features. These adjustments can quickly add thousands to the project cost, and add time to the project as well. But having a well-designed layout can optimise your space and functionality which makes it a worthwhile investment.

Before you decide on a major layout change, consider whether the benefits of a new layout design outweigh the additional costs. In some cases, small adjustments to the current layout can still improve the bathroom’s functionality without the need for a complete reconfiguration. Consult with a professional bathroom renovator or designer to help you decide on the best approach to achieve your desired results while staying within your budget.

What is the Cost of Breakdown for Different Renovation Components?

When planning a bathroom renovation, it’s helpful to understand the breakdown of various components, each having its own costs and variables. Here’s a detailed breakdown of where your budget is more likely to go:

1. Demolition and Waste Removal

demolition and proper disposal are the first stages in a reno

Demolition is the first major step in a bathroom renovation. The cost in Sydney usually ranges from $900 to $1,400 for a complete strip-out. This involves removing old fixtures, tiles, and cabinetry to prepare the space for new installations. If some elements are kept intact like tiles or fixtures, the costs can be lower.

Proper waste disposal is also important. According to the NSW Environment Protection Authority (EPA), construction and demolition waste must be managed responsibly to avoid fines and adhere to best practices. Skip hire fees in Sydney start around $590 for a 2-cubic metre bin for general waste while larger bins can cost up to $1,030. These fees vary depending on the type of waste and the size of the bin needed. In some cases, hazardous materials like asbestos may be present in older homes which requires specialised removal. This can increase the demolition costs due to safety regulations and additional handling.

2. Plumbing and Electrical Work

Plumbing and electrical updates are essential parts of most bathroom renovations with costs often falling between $1,500 to $5,000 or more depending on the extent of the work. Plumbing services generally charge between $100 to $150 per hour. Moving fixtures such as sinks, showers, or toilets will increase costs due to the need for extensive plumbing adjustments. Electrical work adds to the budget especially if you’re installing new outlets, lighting, or underfloor heating. Electricians charge similar hourly rates, with fees of around $100 to $150 an hour. 

Hiring licensed professionals is important for safety and compliance with building standards, making it a necessary investment if you want safety, quality and durability.

3. Tiling and Floor Installation

Tiling and flooring are visually impactful elements in a bathroom renovation. The cost of tiling and flooring generally ranges from $2,000 to $6,000 or higher depending on the material and complexity. Basic ceramic tiles are budget-friendly starting at around $30 per square metre while high-end materials like porcelain or natural stone will drive up costs upwards of $100 per square metre or more. Tiling labour in Sydney can vary widely from $50 to $120 per square metre depending on the complexity of the pattern and tile size. If you want high-quality installation, you need to allocate a portion of your budget to skilled tilers if you want a durable, moisture-resistant, and long-lasting finish.

4. Fixtures and Fittings

custom fixtures are more expensive than standard ones

Fixtures and fittings like bathtubs, vanities, and showers make up a significant portion of a bathroom renovation cost. The prices can range from $2,000 to over $10,000 depending on your choices. Standard options are more affordable, while designer or custom fixtures like freestanding tubs, frameless glass showers, and custom vanities come at a premium. For example, a basic shower screen installation starts around $400 with frameless options costing up to $600. These elements form the bathroom’s look and functionality so choosing quality fixtures can make a lasting impact on aesthetics and usability.

5. Painting and Finishing Touches

The final touches, including painting and small fixtures like towel racks, generally cost between $500 to $1,500. Using quality, moisture-resistant paint is highly recommended to help prevent mould and mildew buildup over time. This stage also includes other finishing touches like putting up a feature mirror or custom hardware which can elevate the space without a significant expense. 

What Are The Hidden Costs to Be Aware Of?

Unexpected costs can arise during a bathroom renovation, especially in older homes where underlying issues are more common. These hidden costs can make a difference in your final budget so planning ahead and setting aside a contingency fund can help you handle these surprises smoothly and avoid delays. These are some hidden costs you need to watch out for:

older homes may have rotten wood underneath

Structural Repairs

Sydney’s property landscape includes many older homes which may reveal underlying structural issues like rotting wood, unstable walls. These issues often appear only once demolition begins. Addressing these issues is essential for a safe, long-lasting renovation but it can increase the costs. The expense will vary depending on the extent of repairs needed so it’s wise to set aside a contingency fund to cover any unexpected findings.

Asbestos Removal

Homes built in Sydney before the 1990s are likely to contain asbestos in materials like flooring, walls, or ceilings. Asbestos removal is highly regulated and must be handled by licensed professionals which can add significant costs with often a few hundred dollars to several thousand dollars depending on the affected area. Proper removal ensures the safety of your household as asbestos poses serious health risks when disturbed.

mould growth may be found in hidden areas

Water Damage or Mould Remediation

Due to the frequent presence of water and steam, bathrooms in Sydney are especially prone to moisture issues. Renovations may uncover water damage or mould growth in hidden areas like behind walls or under flooring. Mould remediation and water damage repair can add to the costs particularly if the problem has spread. Investing in moisture-resistant materials can help prevent future issues.

Plumbing and Electrical Upgrades for Compliance

Older Sydney homes may have outdated plumbing or electrical systems that no longer meet modern standards. To ensure safety and compliance with current codes, these systems often need updating during renovations which can add to the overall cost. Licensed professionals should handle these upgrades to avoid safety hazards and to ensure compatibility with your new fixtures.

How Does the Age of My Home Affect Renovation Costs?

some old houses might have underlying issues or outdated systems

The age of your home can significantly impact the scope and cost of a bathroom renovation, especially for older properties in Sydney. Many older homes often have outdated plumbing and electrical systems which would require upgrades to meet current standards. These updates will add to the renovation costs. Another issue of older homes is the potential for hidden structural issues. Rotting floorboards, weakened walls, and poor waterproofing often come to light once the demolition begins. You will need to address these issues to ensure your renovation lasts but this could lead to unplanned expenses. Older Sydney homes are also more likely to contain hazardous materials like asbestos or lead paint which will require special handling and removal.

If your property is heritage-listed, you may also face additional regulations and approvals as heritage guidelines often require preserving certain architectural features. This can increase both the time and cost of the renovation. Lastly, the layout of an older bathroom may not be optimised for modern use as old spaces might have cramped spaces or awkward fixture placements. All these factors can make renovations in older homes more complex and costly, however, it’s always on a case-by-case basis. Many older homes do not pose any of the issues mentioned earlier and the bathroom renovation is simple and straightforward.

Can I Get Financing for a Bathroom Renovation?

consider various financing options for your renovation

A bathroom renovation is a valuable investment but not everyone has the funds readily available for it. Fortunately, several financing options can make the process more affordable and manageable for homeowners. 

Personal Loans and Home Equity Lines of Credit (HELOCs)

Personal loans are a popular option to finance a bathroom renovation as they offer a lump sum without requiring collateral. These loans are unsecured which means you won’t need to use your home as a security. However, this could entail higher interest rates. For a mid-sized renovation, you might look at a personal loan with a fixed interest and repayment term of three to five years which allows you to pay off the loan steadily over time.

A Home Equity Line of Credit (HELOC) may be more advantageous if you have significant equity in your home. HELOCs allow you to borrow against your home’s equity with flexible terms and often lower interest rates than personal loans. This could be more beneficial for larger renovation projects since it provides access to funds with lower payments and can be drawn upon as needed. To explore various available lines of credit options, consider visiting RateCity’s comprehensive comparison page.

Government Grants or Energy-Efficient Rebates

In some cases, government grants or incentives may be available for renovations that include energy-efficient updates. Installing water-saving fixtures like dual-flush toilets or low-flow showerheads can potentially qualify for rebates or discounts under environmental initiatives. Many of these programs, provided by local councils or state governments, can help offset costs, especially when sustainability is a priority in your project. To see which current rebates and grants might be available for your renovation, you can explore NSW’s current programs. While these grants may not cover an entire renovation, they can offset some costs.

Payment Plans Offered By Contractors

Many contractors and renovation companies offer in-house financing or payment plans, making it easier to manage costs over time. Payment plans allow you to break down the total cost into monthly payments over six months, a year, or even longer depending on your contractor’s terms. Some contractors may even offer interest-free options if you pay within a set period but others may have interests or fees attached. You can discuss these options with your contractor before starting the project and can help you determine which flexible financing approach suits your budget and timeline.

What is the Return on Investment (ROI) for Bathroom Renovations in Sydney?

a well-made bathroom yields a stronger ROI

Bathroom renovations can significantly increase a property’s appeal and value. While it’s difficult to quantify an exact return on investment as it’s highly dependent on the local property market, type of renovation and the total costs. However, generally speaking, homeowners can expect to see a return on investment (ROI) of about 60% to 70% on average but this could still depend on the quality and scale of the upgrades. Properties with modern, well-designed bathrooms often attract more buyers and even lead to faster sales. If you live in a high-demand suburb, having a well-executed bathroom renovation with quality finishes can set your property apart. Buyers are generally more willing to pay a premium for homes that are move-in ready and don’t require immediate updates.

Several factors can influence the ROI of bathroom renovations. High-quality workmanship and materials are essential as buyers like renovations that are durable and visually appealing. A modern look and eco-friendly features are some elements that buyers expect in Sydney’s market. Location within Sydney is also a key factor since suburbs with higher property values yield a stronger ROI on premium finishes while more affordable areas benefit from mid-range upgrades. Matching the style and level of finishes to local market expectations helps the renovation to appeal to buyers and maximises returns.

How Can I Save Money on My Bathroom Renovation?

The good news for some homeowners is that a bathroom renovation doesn’t have to break the bank. You can reduce costs with a few strategic choices while still achieving a high-quality result. Here are some practical tips for saving money on your project:

choose cost-effective materials like porcelain tiles

If you’re on a budget, you can choose affordable yet durable materials to give your bathroom a fresh look without stretching your budget. If you love the look of marble or granite, you can explore other options like quartz or porcelain slabs that mimic these premium materials at a fraction of the cost. Check out these porcelain slabs from Avant Stone.

Choose Cost-Effective Materials Without Compromising Quality

Shop Around for Deals and Factory Seconds

When planning a bathroom renovation in Sydney, exploring factory seconds can be a cost-effective strategy. Retailers often offer discounted items with minor imperfections that don’t affect functionality. Or they may heavily discount discontinued product lines. These products, including vanities, shower screens, and lighting fixtures, provide high-end aesthetics at reduced prices.

DIY the Finishing Touches

While you’ll likely require licensed professionals for plumbing and electrical work, there are still plenty of finishing tasks that you can handle yourself. Painting, adding new cabinet hardware, installing towel racks, or assembling shelving are all achievable DIY projects. You may also apply a self-adhesive splashback which can make a big impact on the look of your bathroom, saving on installation fees and adding a personalised touch.

every design detail should be planned beforehand

Plan Each Detail to Avoid Last-Minute Changes

Renovation changes after the project starts often lead to delays and added expenses. Before you start, you need to map out every detail of the design, from fixture placements to colour choices. If you’re unsure about certain elements, you can consult a designer or contractor to create a solid plan and minimise the risk of expensive adjustments once work is underway.

Invest Where It Matters Most for Lasting Value

Investing in quality can help you save more over time, especially in areas like waterproofing, plumbing, and structural work. Spending a little extra on these essential areas reduces the need for future repairs which makes your bathroom more resilient and cost-effective over the long term. 

Should You Pay Extra for High-Quality Materials?

When planning a bathroom renovation, it’s tempting to cut costs on materials. But in some cases, investing in high-quality materials can pay off in durability and overall value. Here are some reasons why spending a little bit more might be worth it:

high-quality materials offer long-term durability

Long-Term Durability and Lower Maintenance Costs

High-quality materials such as porcelain tiles, stone countertops, or brass fixtures are designed to withstand daily wear and tear. These materials are less prone to chipping, staining, or warping over time, making them a better choice for a space that experiences heavy use. While they come with a higher initial price, they often need less maintenance and fewer replacements which can save you money in the long run. 

Enhanced Aesthetics and Property Value

Premium materials can elevate the overall look and feel of your bathroom. These features can add a level of sophistication that potential home buyers notice. A high-end bathroom renovation can also add to your property’s resale value as buyers appreciate quality finishes and they are more willing to pay a premium for homes with aesthetically pleasing, durable and well-designed spaces.

marine-grade steel fixtures are perfect for coastal climate

Better Resilience in Humid and Coastal Environments

The coastal climate can lead to higher humidity levels which affect materials like wood, metal and even the tile grout. By choosing quality materials that can withstand humidity, the risk of warping, rusting, and mould buildup can be significantly reduced. Marine-grade steel fixtures can prevent rust, while waterproof vanity tops like ceramic provide better protection against moisture infiltration compared to cheaper alternatives like laminate, helping you avoid costly repairs in the future.

Peace of Mind and Overall Experience

Quality materials can also improve your day-to-day experience. High-quality taps, showerheads, and cabinetry perform better and add a sense of luxury to your bathroom. Knowing that your bathroom is built to last gives you peace of mind, letting you enjoy the space without worrying about frequent repairs or replacements.

How Can I Ensure My Renovation Stays Within Budget?

plan and review your expenses to stay within budget

Detailed Planning

You need to start with a comprehensive plan that outlines each aspect of the renovation. From materials to labour and fixtures, every detail should be considered to avoid unexpected costs later. Research the costs of your desired materials and finishes, and get quotes from contractors to set a realistic budget. If possible, you should request itemised quotes for each part of the project since this can help you identify areas where you may want to adjust quality or scope to save costs. Include a 10-15% contingency fund for unexpected expenses like repairs or upgrades to outdated plumbing. This will provide you peace of mind and keep your budget intact if surprises arise.

Regular Monitoring

During the renovation, keep track of your expenses closely. Regularly review your spending against the budget so you can spot areas where costs are rising. If one aspect exceeds your initial estimate, look for ways you can save in other areas. Staying engaged with your budget at each stage of the renovation is key to preventing overspending.

Open Communication

Clear communication with your contractor can make a big difference in controlling the costs of the renovation. Before you start the work, discuss your budget in detail and ask for regular updates on expenses. If there are unexpected costs that will come up, it’s important that your contractor also has transparent communication with you so you can make informed decisions regarding adjustments without risking budget overruns.

Conclusion

A bathroom renovation is a valuable investment that will enhance your home’s functionality and market appeal, especially in a competitive city like Sydney. By understanding the costs involved and planning strategically, you can manage your budget effectively and make informed choices that align with your goals. From choosing high-quality materials to incorporating eco-friendly features, each decision can contribute to the value and longevity of your bathroom renovation.
