Why Are Bathroom Renovations So Expensive?
Bathroom renovations are expensive because they require multiple skilled trades, strict compliance with waterproofing standards, and a high level of detail in a relatively small space.
Unlike other areas of the home, bathrooms combine plumbing, electrical work, tiling, and structural considerations all in one area. Each stage must be completed in the correct order and to a high standard, which increases both labour time and overall costs.
This is why bathroom renovations are often one of the most complex and labour-intensive projects in a home.

How Many Trades Are Involved in a Bathroom Renovation?
A standard bathroom renovation typically involves a wide range of specialised trades, including:
- Demolition specialists
- Project managers
- Plumbers
- Electricians
- Tilers
- Waterproofers

- Glaziers
Each trade plays a critical role, and coordinating them correctly is essential to delivering a high-quality result.

Where Your Bathroom Renovation Budget Goes
This cost breakdown reflects how a typical bathroom renovation budget is distributed across different trades and materials.
As you can see, no single component dominates the cost. Instead, it’s the combination of labour, materials, and specialised work that adds up quickly.
Tiling and waterproofing are often among the highest-cost items due to the time, skill, and compliance requirements. Fixtures and fittings also play a significant role, particularly in mid-range to high-end renovations.
This is why bathroom renovations can feel expensive: there are many moving parts, and each must be completed correctly to ensure a high-quality, long-lasting result.
At Banana Bathrooms, we manage all of these trades under one roof to ensure your renovation runs smoothly from start to finish.

Why Do Some Bathroom Renovations Cost Less?
You may have heard of someone completing a bathroom renovation for under $20,000, and in some cases, that’s possible. However, there are usually key differences in scope, materials, and workmanship.
Lower-cost renovations often involve compromises such as:
- Keeping the existing layout to avoid plumbing changes
- Using lower-cost fixtures and fittings
- Reducing tiling coverage (for example, tiling only wet areas)
- Managing parts of the project yourself
- Shorter timelines or fewer trades involved
While these approaches can reduce upfront costs, they can also impact the longevity, functionality, and overall finish of the bathroom.
A full bathroom renovation, like those completed by experienced professionals, typically involves a complete rebuild with proper waterproofing, high-quality materials, and coordination across multiple trades
This is why it’s important to compare quotes carefully, not just on price, but on what’s actually included.
Why Professional Bathroom Renovations Matter
Bathroom renovations involve far more than just design and installation. They require strict compliance with Australian building standards, particularly for waterproofing, plumbing, and electrical work.
Mistakes in these areas can lead to costly repairs down the track, including water damage, mould, and structural issues.
Working with experienced professionals ensures that every stage of the renovation is completed correctly, safely, and to a high standard. It also provides peace of mind that your bathroom will perform well for years to come.

What Increases the Cost of a Bathroom Renovation?
Several key factors can significantly impact the cost of a bathroom renovation. Understanding these will help you make informed decisions when planning your project.
Changing the Layout or Plumbing
Moving plumbing points such as toilets, showers, or vanities can quickly increase costs. This requires additional labour, materials, and sometimes structural adjustments, making it one of the biggest cost drivers.
High-End Fixtures and Fittings
Premium tapware, custom vanities, freestanding baths, and designer basins can elevate the look of your bathroom, but they also come at a higher price point.
Tiling and Waterproofing
Tiling is one of the most labour-intensive parts of a bathroom renovation. Full-height tiling, feature tiles, and complex layouts require more time and skill, increasing both labour and material costs.
Electrical Upgrades and Lighting
Adding LED mirrors, feature lighting, heated flooring, or additional power points can increase costs due to extra electrical work and compliance requirements.
Custom Design and Finishes
Bespoke cabinetry, niche shelving, skylights, and unique layouts require more detailed planning and craftsmanship, which adds to the overall cost.

By understanding these cost drivers, you can prioritise where to invest your budget and where you can save without compromising quality.
How to Plan Your Bathroom Renovation Budget
Properly planning your bathroom renovation is one of the most effective ways to control costs and avoid unexpected expenses.
Start by setting a realistic budget based on your goals, the size of your space, and the level of finishes you want to achieve. Understanding your priorities early will help you allocate your budget more effectively.
Set Clear Priorities
Decide what matters most in your renovation. Whether it’s high-end fixtures, custom design features, or keeping costs under control, having clear priorities will guide your decisions throughout the project.
Keep Your Layout Where Possible
Retaining your existing layout is one of the easiest ways to reduce costs. Avoiding major plumbing changes can significantly lower your overall renovation budget.
Allow for a Contingency Budget
Unexpected issues such as water damage or outdated plumbing can arise during a renovation. Setting aside an additional 10 to 15% contingency helps ensure you’re prepared for any surprises.
A well-planned renovation not only keeps your budget on track but also ensures you achieve a result that suits your lifestyle and adds long-term value to your home.
Understanding Bathroom Renovation Costs
Bathroom renovations are one of the most complex and labour-intensive projects in the home. From multiple trades and strict compliance requirements to high-quality materials and detailed finishes, every element contributes to the overall cost.
By understanding what drives these costs, you can make informed decisions about your renovation and prioritise what matters most for your space, style, and budget.
