Bathroom Renovation Cost: A Complete Pricing Guide for Australian Homeowners

Bathroom Renovation Costs in Australia: What Are You Actually Paying For?

Having worked on my fair share of bathroom renovations that have fallen apart because the clients didn't know exactly what they were paying for, let's have a quick breakdown here.
Bathroom Renovation Cost in Australia is a broad scope, from $8,000 and upwards, where a budget cosmetic refresh sits on the lower end, to $60,000 and above for a full-scale luxury renovation with structural modifications. There are a few key determinants to how much bathroom renovation cost will set you back, including room size, scope of works, and materials, to mention a few. For instance, a small ensuite under 5 square metres with a fresh coat of tiles and new fixtures will sit at the lower end. In contrast, renovating a medium-sized 10m² main bathroom involves a complete reconfiguration of the bathroom, plumbing and retiling, and high-end finishes. This is going to start from $30,000 up to $60,000 plus.
What often surprises people when it comes to bathroom renovation costs is the expenditure that goes below the wall. Waterproofing for example, depending on the scope, starts at $1,500-$3,500, and can cost more on a larger area. Plumbing is another one, as moving a single drain point can add $2,000 to your bill, whereas installing electrical wiring, for things such as exhaust fans, heated towel rails, and power points can set you back around $1,500-$3,000. You'll never see this in any "before and after" photos, but it's these types of hidden costs that often determine the quality and durability of your bathroom renovation.

Itemised Price Breakdown: Labour, Materials and Hidden Costs

In the event you had a budget bathroom renovation costing $25,000, your funds are most likely be utilised as follows: labour will account for around 45% ($11,250), materials 35% ($8,750), and the remainder 20% ($5,000) will be for permits, waste removal and contingency.
A breakdown of your renovation costs by trades will see the plumber charge $80-$120 per hour, the electrician charge $90-$130 per hour, the tilers charge $80-$110 per hour. One of the more labour-intensive jobs will be the tiling which will cost $2,500-$5,000, accounting for a large part of your bathroom renovation cost.
The tiling budget is separate from the plumbing and the electrical work mentioned above. As for materials, you can expect to pay anywhere from $1,500-$5,000 for a bath/shower unit, between $1,000 and $3,500 for your bathroom vanity, $500-$2,000 for tapware, and somewhere around the $1,500-$3,500 mark for your flooring. And then there's painting which, for a standard bathroom would cost around $500 to $1,000. Don't also overlook the extra bathroom renovation costs, such as asbestos testing ($300-$500, especially for homes built prior to 1990), the skip bin (approximately $400-$800), and building permits ($500-$1,500 if you are planning on making significant structural changes).

Budget-Friendly Renovations vs Premium: Where Your Money Goes

The biggest difference here between the $10,000 and the $40,000, I'd say is down to choice. Not necessarily quality or value, though they can play a part.
A low to mid-range renovation for $10,000 is more than realistic, and a standard $900 acrylic bath/shower unit, standard ceramic tiles at $40/sqm and basic tapware (between $200-$400) can be found and used to achieve your desired result. You keep existing plumbing in the same positions, use stock vanities and sinks, and choose to spend on the items that make a difference in your day-to-day use (the tapware and shower for instance), while economising on things that have no bearing or function on your lifestyle.
At the premium end, a $40,000 renovation typically features a designer bath at $3,000 or more, porcelain tiles which start between $60-$100/sqm, premium quality tapware that starts from around $1,200 upwards, floor heating, heated towel rails and custom vanities. That labour element goes up too, as it takes a higher level of skill to fit and fix more costly materials properly. This is what I consider essential spending: waterproofing (always), quality tapware (since you use it every day), and tiles (they influence the look of your bathroom for the next 15 to 20 years or more). It is possible to save your budget on things like accessories, mirrors and paint, and you can change these relatively quickly later if needed.

How to Renovate a Bathroom Without Exceeding Your Budget

I have seen many bathroom renovations fail when it comes to budget overruns, so over the years, I have learned and put together a few rules:
Know what your budget is before starting any work and be sure to set aside another 15 to 20 per cent in your budget to cover contingencies. This is an absolute must. Something always arises, such as a pipe that has corroded in the wall, unexpected asbestos, or a delivery delay pushing the start date for your tradespeople. If you have used your contingency to cover something and there is money left over, consider the money you have saved for something else, such as a higher-quality showerhead!
At least 3 fixed price quotes from licensed tradespeople. Not estimates, fixed price quotes. The two are very different when the bill lands on your doorstep. Get quotes, and compare the same line items across each contractor to ask, exactly how much does a bathroom renovation cost for a scope like mine?
Don't change the design or layout after construction starts. It is easy to decide to change your mind about your bathroom's design or layout once the tilers have started, but these decisions should be made before the builders and tilers commence. A bathroom is such a small space, so it can be hard to decide on what tiles, tapware, vanity, bath, and accessory combinations will best suit your tastes and budget!
Use standard sizes where possible. A standard bath tub is 30 per cent less expensive than a custom-made product. Standard vanities also connect to standard pipes so require less modification and less labour to install.

Regional Variations and Contractor Rate Comparison Across Australia

If you are getting quotes and wondering exactly how much does a bathroom renovation cost Australia-wide, that depends in large part on your location. For most trades, labour costs in Sydney and Melbourne sit at between $100 to $130 per hour. In Brisbane or Perth, this might be between $85 and $110. Regional and rural areas have a lower labour rate (perhaps $70-$90/hour) but expect to pay 10 to 15 per cent more for material freight to remote locations.
In other words, a medium scope bathroom renovation might cost you $25,000 in a regional Queensland town, but $35,000 to $40,000 in inner-city Sydney. Material costs are largely the same nationwide, but the labour differential is significant.
Supply chain also comes into play. If you are looking for a certain drop in bathtub, or freestanding bathtubs with a specific finish, there can be an 8 to 12-week lead time for these items in regional areas. This also will affect your schedule and therefore could push up your cost if your tradespeople are on standby while waiting for product delivery.
