April 22, 2024by admin

Bathrooms are one of the most significant parts of any household which needs care and maintenance from time to time. However, long term negligence can lead to several problems including leakage, drainage problems, mould which ultimately increase the risks of infectious diseases. Most of the time, when homeowners go for bathroom renovation, they discover many underlying problems which need to be fixed as soon as possible which eventually elevate the bathroom renovation costs.

Renovating a bathroom involves various elements, each with its own set of costs. This guide delves into the specifics of bathroom renovation costs in Australia, providing homeowners with detailed information to plan their budget effectively.

Average Bathroom Renovation Cost

The average cost of a bathroom renovation in Australia has seen a significant increase in recent years. According to Thomas Devitt, senior economist at the Housing Industry Association of Australia, the average spend on a bathroom renovation now stands at $26,000, up from $21,000 previously. This rise in cost can be attributed to several factors, including escalating labour costs and shortages of key materials in the market.

However, beyond these overarching factors, several other variables contribute to the total price of a bathroom renovation:

  • Size of the Bathroom
  • Location
  • Permit Costs
  • Structural Work
  • Luxury Elements
  • Involvement of Other Tradespeople

Understanding Bathroom Renovation Cost Breakdown

Bathroom renovations involve different professionals, each charging varying hourly rates. While bathroom renovators typically charge around $98.13 per hour, it’s essential to note that rates can fluctuate based on various factors. These factors include the size of your bathroom, the scope of work required, and the level of expertise needed. Expect hourly rates to range from $50 to $121, with the final cost contingent on specific project intricacies. Let’s first understand the hourly rates of bathroom renovators.

Plumbing Costs

Plumbers typically charge a call-out fee ranging from $60 to $150, alongside an hourly rate of $100 to $150. These rates may vary based on geographical location and the plumber’s expertise. Considering the intricacies of bathroom plumbing, it’s common to require the services of a plumber during renovations. Tasks such as installing new fixtures, rerouting pipes, or addressing existing plumbing issues contribute to the overall cost.

Electrical Costs

Similarly, electrical work is a vital component of bathroom renovations, encompassing tasks like installing lighting fixtures, outlets, and ventilation systems. Electricians often charge a call-out fee within the range of $60 to $150, coupled with an hourly rate typically falling between $80 to $100. While not every renovation project may necessitate extensive electrical work, ensuring proper wiring, safety measures, and compliance with building codes is paramount.

Tiling Costs

Tiling is another significant aspect of bathroom renovations, contributing to both aesthetic appeal and functionality. Estimating the cost of tiling involves considering factors such as the size of the area, labour expenses, and the price of tiles. While some tilers quote based on hourly rates, opting for a square metre rate provides a more transparent understanding of costs.

For instance, a tiler may charge between $50 to $130 per square metre for labour. Therefore, for a bathroom measuring 17 square metres, labour costs could range from approximately $850 to $2,000 or more. Additionally, tile prices vary widely, with luxury options costing $150 or more per square metre, while standard tiles fall within the $30 to $55 per square metre range.

To calculate the total tiling cost, one can add the labour expenses to the tile costs based on the bathroom size. For example, for a 17 square metre bathroom, the total tiling cost might range from $1,200 to $4,500 or higher, depending on the selected tiles and labour rates.

By understanding these cost breakdowns, homeowners can better plan their bathroom renovation budgets and ensure a smooth and successful project execution.

Trade Average Hourly Cost
Plumber  $100 – $150
Electrician  $80 – $100
Tiler $50 – $130 per sqm
General Labour $100 per hour

It’s crucial to request detailed quotes from contractors to understand the exact breakdown of labour and materials.

For those on a tight budget, opt for smaller vanities around the 600-millimetre mark. Both floor standing and wall-hung models are viable options, offering a range of styles and colours at affordable prices. Consider a flat wall mirror instead of a mirror cabinet to minimise costs.

Lighting Options

Basic lighting can be achieved with recessed halogen or LED downlights, typically installed in sets of two or four. Alternatively, consider a heat-light-fan ceiling light for a cost-effective solution. 

Basic Flooring

Ceramic tiles are the go-to choice for low-cost bathroom flooring, starting from around $50 per square metre. Vinyl and linoleum are also affordable alternatives, offering a variety of styles and patterns while ensuring slip and water resistance.

Mid-range Bathroom Renovation

Vanities and Fittings

Invest in double bowl vanities for added functionality and aesthetic appeal, with entry-level models priced between $1,500 to $2,000. Custom-made vanities offer a personalised touch, integrating innovative features such as extra-large drawers and built-in taps.

Lighting Options

Consider enhancing natural light with larger window openings or installing skylights for a light, airy atmosphere. Mid-range lighting options may include wall lights around the mirror or a statement chandelier to elevate the bathroom’s ambiance.

Mid-range Flooring

Porcelain tiles offer durability and versatility, making them a popular choice for mid-range bathroom renovations. Wood-look porcelain tiles create a striking feature floor, complementing a range of wall tile options for a stylish finish.

Luxury Bathroom Renovation

Vanities and Fittings

In case of luxury bathroom renovation, you can go for custom made vanities by incorporating luxurious materials such as stone, wood, or glass. Consider wall-hung vanities with large drawers and integrated features like touchless taps.

Lighting Options

For lighting, you can include wall lights, chandeliers, or custom lighting displays. Sensors can add a touch of convenience, automatically activating lights upon entry and offering customizable settings for added luxury.

High-end Flooring

Underfloor heating systems are common in luxurious bathrooms. Alternatively, electric underfloor heating systems offer a popular and accessible option for keeping your bathroom warm.

Additional Bathroom Renovation Costs

Some bathroom remodel costs are not immediately obvious but can significantly affect the budget. Unforeseen expenses can quickly derail your plans and budget if not adequately anticipated. Here are some common hidden costs to be aware of during the renovation process:

Unforeseen Structural Issues

One of the most prevalent hidden costs in bathroom renovations is the discovery of unexpected structural flaws. These issues can range from damaged flooring, walls, or ceilings to deteriorated pipes causing leaks and mould. Conducting a thorough inspection before commencing renovations can help identify potential problems early on, allowing for proper budget allocation and timeline planning.

Removing and Disposing of Old Fixtures

Often overlooked, the cost of demolishing and disposing of old fixtures can be substantial. Items such as asbestos, oversized fixtures, or outdated installations may require specialised handling and disposal, adding to the overall renovation expenses. It’s essential to budget for labour and disposal costs to ensure the safe and efficient removal of old bathroom elements.

Electrical Changes

Introducing new lighting fixtures or rewiring existing electrical systems can incur significant costs. Hiring a qualified electrician to assess the wiring and address any faulty components is essential for safety and compliance. Budgeting for potential electrical upgrades or rewiring ensures that these expenses do not catch you off guard during the renovation process.


Waterproofing is a critical component of any bathroom renovation to prevent water damage and mould growth. Ensuring proper waterproofing is essential for protecting the integrity of your bathroom floor and preventing costly repairs in the future. Allocating a portion of your budget to professional waterproofing ensures that this vital aspect of the renovation is not overlooked.

Hiring Additional Professionals

When working on a bathroom renovation project, it’s essential to consider the expertise of various professionals beyond plumbers, electricians, and tilers. While these core tradespeople handle the fundamental aspects of your renovation, additional professionals can increase the quality and functionality of your space, albeit at an extra cost. Let’s explore some key professionals you might consider hiring and how they can enhance your renovation experience.

Interior Designer

An interior designer brings invaluable expertise to your renovation, offering insights into colour schemes, material selection, and space optimization. With their guidance, you can achieve a cohesive and visually appealing bathroom design that reflects your style preferences while maximising functionality.


For renovations involving structural changes or complex designs, an architect’s involvement is indispensable. They ensure compliance with building codes, obtain necessary permits, and provide innovative solutions to enhance your bathroom’s layout and aesthetics.

Project Manager

A project manager plays a crucial role in streamlining the renovation process, coordinating tradespeople, and ensuring the project stays on track and within budget. Their expertise minimises delays and facilitates effective communication between all parties involved.

Waterproofing Specialist

Proper waterproofing is essential to protect your bathroom from moisture damage. Hiring a waterproofing specialist ensures thorough waterproofing of all surfaces, safeguarding your investment and prolonging the lifespan of your renovation.

Custom Cabinetry Maker

For tailored storage solutions that maximise space efficiency, consider hiring a custom cabinetry maker. While their services come at a premium, custom cabinets offer unmatched quality, fit, and design versatility tailored to your specific needs.

Glass Specialist

If you’re incorporating custom glass features such as frameless shower screens or mirrors, a glass specialist’s expertise is invaluable. They ensure precise measurements, flawless installation, and stunning visual impact, elevating the luxury and sophistication of your bathroom.

Lighting Consultant

A lighting consultant enhances your bathroom’s ambiance and functionality through strategic lighting design. They focus on creating a well-lit, energy-efficient space that complements your aesthetic preferences while optimising task lighting and mood lighting.

Heating and Ventilation Expert

To ensure year-round comfort and functionality, consult a heating and ventilation expert. They recommend and install systems such as underfloor heating, heated towel rails, and efficient ventilation systems tailored to your bathroom’s size and usage.

Selecting the Right Tradespeople

Choosing qualified professionals is crucial. Here’s how to ensure you hire the right people:

Check Credentials

Before hiring any tradesperson, it’s crucial to verify their credentials. Make sure that they are licensed to perform the necessary work in your area and that they carry adequate insurance coverage. This protects you from liability in case of accidents or damages during the renovation process.

Read Reviews

Take the time to research and read reviews from previous customers. Online platforms and review websites can provide valuable insights into the quality of workmanship, professionalism, and customer satisfaction levels of potential tradespeople. Pay attention to both positive and negative reviews to get a comprehensive understanding of their reputation.

Get Multiple Quotes

Don’t settle for the first tradesperson you come across. Instead, request quotes from multiple contractors to compare prices and services offered. This allows you to make an informed decision based on factors such as cost, timeline, and the scope of work. Be wary of unusually low quotes, as they may indicate subpar quality or hidden costs.


Planning a bathroom renovation requires a detailed understanding of bathroom renovation costs associated with different stages and components of the project. By educating yourself and carefully selecting your tradespeople, you can achieve a balance between cost, quality, and style, ensuring your renovated bathroom meets your needs and budget.

Whether you’re aiming for a budget-friendly upgrade or a luxurious spa-like retreat, informed decision-making and careful planning will pave the way for a successful and rewarding renovation experience.
