Bathroom renovation costs? 

Anywhere from $9,000 to $40,000 depending on a number of factors. If you want an approximate average, the Housing Industry Association (HIA)’s 2017/2018 Kitchens and Bathrooms Survey concluded the average bathroom renovation cost is approximately $17,000. 

Renovation Cost factors: 

  • Bathroom size
  • Chosen materials
  • Chosen fittings
  • Labour costs
  • Permits (if required) breaks the cost of renovating a bathroom into three ranges; high, medium and low. Let’s discuss. 

High Range $30,000 + 

The over $30,000 range provides luxury bathroom renovations, including the use of premium materials and fittings. For this higher price, you are able to add any design elements you desire and are not restricted to the current layout. You will be working with an industry leader, with years of experience specialising in such projects. You are able to indulge on porcelain tiles, double showers, hanging vanities and glass tubs. Essentially, you are paying for the best of the best. 

Medium Range $15,000 - $30,000 

The medium range is what most people budget for with their bathroom renovation. You can expect a large range of tiling, shower designs and gorgeous bathtubs to choose from. You may be slightly more restricted when it comes to changing plumbing or electrics but as a whole the medium range assures a great bathroom renovation. Particularly for those who know where in the bathroom is best to invest their budget. 

Low Range under $15,000 

It is to be expected that a lower budget will restrict your choices. You will likely have to opt for large format porcelain tiles, framed shower screens and simple designs. While some professionals may offer low range prices, you may have to work with a less experienced professional depending on how low your budget is. 

WARNING - always encourages our readers to beware of falling victim to low prices that promise a lot. While it can tempt the best of us, often long term issues can arise as the job has not been properly carried out. 

What Factors Influence the Cost of Bathroom Renovation

Bathroom Plumbing Costs 

Plumbers can charge anywhere from $100-$150 per hour, when receiving a quote from a plumber you should ask for an itemised quote so you know exactly what costs what.

Bathroom Tiling Costs 

Most bathroom tilers quote by the square metre, the price ranges between $35 to $180 per square metre. Be sure to account for floor and wall tiles and your chosen material. 

Bathroom Bathtub Costs 

A plumber is likely to charge anywhere from$350 to replace and fit a bathtub, bearing in mind that your choice in tub may affect this price. Brand new tubs begin at $400 upwards. 

Bathroom Showerscreen Costs

This price of a showerscreen will vary depending on your choice in size and design, however a basic showerscreen can cost as little as $400 to install. The cost of purchasing a shower screen begins at $600. 

Bathroom Toilet Costs

Again, depending on your choice in toilet the price can vary. Toilet prices range between $150  to $750. 

Bathroom Vanity Costs

If you are chasing a 900mm wall hung vanity with hidden handles expect to pay $467, a 750 mm floor standing console vanity will be closer to $849, a 1500 mm double bowl vanity costs around $1000 and a 1200 mm wall hung vanity with integrated ceramic basin will be approximately $1360. 

Bathroom Waterproofing Costs

Absolutely essential! The average sized bathroom will cost anywhere from $500 to $750 to properly waterproof.


Labour costs for Bathroom Renovations

Labour costs also have to be taken into consideration. Depending on the service provider, they might either charge an hourly rate, day rate or an overall cost for the project. You can expect to pay around $100 an hour for a qualified professional.

Paying a fair price for the services of a qualified tradesperson ensures that you will be receiving high quality workmanship, so it’s important not to only base your decision on the cheapest quote you receive, as this may be indicative of the level of service provided.

It’s best to compare bathroom renovation quotes from several qualified tradespeople to get an idea of the price range, and select one based on their past customer reviews, photos of their work and their experience. Make sure you clarify whether the cost of their services is inclusive or exclusive of materials used, so there is a clear understanding of the costs involved from the outset.

You can potentially save costs by hiring individual contractors to handle each component of the bathroom renovation separately, as opposed to hiring a bathroom renovation specialist or builder to manage the separate tradies. However, you have to be cautious of job schedules and ensure each tradesman will complete the bathroom renovation in the required timeframe. Further, you have to ensure each service provider can undertake their work without interfering with the other.

Bathroom fixtures

Another important factor that determines the cost of bathroom renovation is the fixtures you select for the design of your bathroom.

Bathroom Fixtures include:

  • bathtubs 
  • vanities 
  • toilets
  • sinks

Depending on the type of quality and design, this will also affect the overall cost of the project.

Fixtures will also require installation and electrical and plumbing lines connected. If these lines are not already in place this will also increase the cost of your bathroom renovation. If the plumbing is not conducted properly, this can cause immense issues and cost you greatly in the long run. It’s best to do your research on how to hire a professional plumber. When it comes to plumbing, we recommend hiring a highly skilled plumbing professional with the appropriate plumbing licence in their state.


When it comes to fixtures, tiles will have a prudent impact on the renovation. To save money on your renovation opt for ceramic tiles rather than marble, stone or decorative tiles. However, you should keep in mind cheaper tiles won’t have the same impact as more expensive, decorative tiles. There are a variety of shower screen options that will also vary in price depending on whether they are framed or frameless, but for inspiration it’s useful to have a look at these shower screens that will leave you breathless.


Bathroom Countertops

People with tight budgets can opt for a single-sink vanity or a pedestal sink made from acrylic or laminate timber. These countertops will cost less than marble or stone benchtops.

Once you have determined an accurate overall cost, you can choose to splurge on a feature piece likes a marble benchtop or decorative tiles to give your space a beautiful finish. 

Make sure you plan carefully and be creative with your choices. At the end of the day, all you need is a beautifully renovated bathroom that fits to your budget.
