A bathroom renovation can cost anywhere from $10,000 to $30,000 or more, depending on the size of your bathroom, and how much your materials, fittings and labour costs are.

Most people spend somewhere in the middle of this range – in fact, the Housing Industry Association (HIA) found $17,000 to be the average cost of a bathroom renovation in Australia.  As you can expect there are a lot of variables that impact how much your bathroom renovation will cost. Factors that will affect the cost of your project include:

  • The size of your bathroom

  • The materials you choose

  • The fittings you select

  • Labour costs

  • Permits costs, if these are required for your job

Let’s take a more detailed look at costs, which we have broken down into three price brackets.

You can break down the cost of a bathroom renovation into three price brackets:

  • Budget cost: $5,000 – $15,000

  • Standard cost: $15,000 – $30,000

  • Premium cost: $30,000+

As a guideline, expect to spend in the region of:

  • $5,000 – $15,000 for a budget or cosmetic renovation of a smaller bathroom using budget materials and fittings.

  • $15,000 – $30,000 for an average sized mid-range bathroom renovation using mid-range materials and fittings.

  • $30,000+ for a high end, premium or luxury bathroom renovation using top of the range materials and fittings.

Let’s take a look at this in more detail, and what you get for your money.

Budget bathroom renovation cost: $5,000 – $15,000

It is possible to do a bathroom renovation on a budget for around $5,000, but this will largely be cosmetic or involve swapping out a few items. Spending up to $15,000 will also involve some compromises, such as keeping all your plumbing and electrics in place. To stay in this budget you will also need to choose large format porcelain tiles in the $30 per square metre range – which are durable and available in a wide range of colours. If you are installing a new shower you will need to stick to a framed shower screen, as well as a standard back to wall toilet and floor mounted vanity.

Standard bathroom renovation cost: $15,000 – $30,000

Budget $15,000 to $30,000 for your project – which is what most people spend, and you get better materials and fittings. You will have a larger range of tiles to choose from in the $50 per square metre range, and could even stretch your budget to more labour intensive mosaics in the shower cubicle. You could also upgrade to a semi-frameless or frameless shower screen, and choose a larger or fancier freestanding bathtub, and bathroom vanity. In terms of moving services, you can make some changes but not major alterations to plumbing or electrics.

Premium or luxury bathroom renovation cost: $30,000+

Budget $30,000 and more and you are likely to want to completely overhaul your bathroom and make major changes to the layout and services. You may want to install a frameless shower screen, in wall cistern and wall hung vanity, as well as a luxurious freestanding bathtub. If you want the best tiles for your walls or floors then look at ranges of porcelain tiles in the $60 per square metre range.

Some of the major costs to plan for in a bathroom renovation include:

  • Plumbing, especially if you are moving plumbing or installing new elements

  • Tiling, which could include floor and wall tiles

  • Frameless shower screen, semi-frameless shower screen or standard shower screen

  • Bath, which could be integrated or freestanding

  • Toilet, which could be a standard version or have an in-wall cistern

  • Vanity, standard or wall mounted which looks cleaner and gives you more floor space

  • Lighting, which could be task, general or mood

  • Waterproofing, to ensure your bathroom doesn’t leak

New baths can range from as little as $400 to thousands of dollars, with stone freestanding versions at the upper end of the scale.

Shower screen costs

Shower screens vary in price according to their size and if they are framed, semi-frameless or frameless, with the latter being the most costly. Expect to pay in the region of $400 to have a basic framed shower screen installed.

It’s good to know what to expect when such a large project is happening in your home. Having a bathroom renovation checklist to carefully plan the project will be a great starting point. This can also help you keep track of your costs. Here is a step by step guide so you have a better idea what jobs happen when. 

1. Design your bathroom

The first step is to work out how your new bathroom will look and work. It needs to be laid be practical if you are going to enjoy using it and spending time in it. There needs to be a logical flow to all the major elements, including the bathtub, vanity, toilet and shower. This can be done on paper, or there are some really nifty apps or 3D modelling tools that can help you nail your bathroom design. Your bathroom builder can help design your bathroom for maximum convenience.

2. Strip out your old bathroom

When your tradies arrive on site the first task is for them to strip out your old bathroom. This is a noisy and often messy job, especially if you are removing the existing wall and floor tiles. They will have to be jackhammered off, which can take a few days depending on how much tile you have.

3. Plan your plumbing

If you are making changes to your plumbing this is when the plumber and/or electrician will relocate all the services. They will mark up all the locations for your new plumbing and make sure all the dimensions are right. You will have to have chosen all your fittings by this stage so they can ensure everything fits and goes in the right place. Moving plumbing can add quite a bit to your overall cost, so think about it before you go ahead with your job.

4. Render those wall

Once the services – plumbing pipework and electricals conduits – are installed the walls will be rendered. This gives your walls a smooth finish ready for tiling or painting. You will generally need to render a wall after old tiles are removed as jackhammering normally takes big chunks out the wall.

5. Prep for tiling

Your tiler will then lay the cement bedding for your tiles. This is crucial if your water is to drain to the waste, and an expensive fix if they get this wrong. Waterproofing comes next, which is not only mandatory according to Australian Standards, but crucial to ensure there are no leaks after tiling is laid. Waterproofing needs to be done by a someone appropriately qualified – usually your tiler, plumber or a dedicated waterproofer.  

6. Tiling

Your tiler can now lay bathroom floor and wall tiling. If you are thinking of laying mosaics tiles, just be aware that tilers will charge more for these as they are more fiddly and take longer to lay.

7. Fit out

Once tiling is done you will begin to see a lot of changes as your bathroom begins to take shape. Your toilet, bathtub, vanity, basin, & tapware will all now be installed by the plumber. An electrician will then install the lighting, exhaust fans and any other electrical items. This is also when your shower screens get installed.
