A well-designed bathroom looks and feels beautiful, as well as optimises functionality. Here, we share our expert guide on bathroom dimensions Australia. This will help you to plan your bathroom or ensuite like a pro as you will know how much space you need to allow for your vanity, shower, bathtub and toilet. And while you are here, don’t forget to grab some bathroom inspirations along the way.
Shower Sizes Australia
In your bathroom allow 1,000mm for both the width and length of the shower cabin. In a tight space, you can consider going to a smaller 900 by 900mm, but anything smaller may feel too confined. The door to the shower cubicle is ideally 650mm wide to grant easy access to it.

Walk in shower dimensions Australia
Open walk-in showers with a single fixed glass panel are still on the wishlist of most bathroom renovators as they make the bathroom look and feel spacious. Aim for a screen of at least 1,400mm in width so that the bulk of the splashes is retained. A shorter glass panel may make you mop up the bathroom floor more often than you would prefer.
Shower screen size
When working towards the standard bathroom dimensions Australia, the height of a shower screen can be anything between 1,900 and 2,100mm depending on your stature. Also, take into account your floor-to-ceiling height. The rule of thumb is, that the higher the ceiling, the taller the screen should be to keep both in proportion.

By the way, if you need an additional bathroom in your house, check out how much space you need to allocate. Maybe it’s less than you think.
Shower head height Australia
It’s visually pleasing to align the installation height of the shower head with the height of the glass screen between 1,900 to 2,100mm. This doesn’t change whether the head is mounted on the wall or on the ceiling. Most importantly, tailor it to your family’s needs.
Shower taps should sit around 1,000mm off of the floor. This ensures that they are accessible to everyone including the kids that are using the bathroom space.
Shower niche height Australia
A shower niche recessed into a wall provides handy space for shampoos and body washes. A good niche size is 600mm wide by 300mm high as this works well with most wall tile dimensions. The recess should be at an accessible height ranging from 900 to 1,200mm off the floor. Also, keep in mind the placement of your niche and whether it’s something you want to make an aesthetic feature of or more for practical use.
Standard vanity height in Australia
Off-the-shelf vanities come in widths of 450, 600, 900, 1,200, 1,500 and 1,800mm whereas the last two sizes can fit two wash basins. A standard vanity depth is 450mm, but they also come in slim versions of only 350mm for narrow spaces.
Wall hung as opposed to floor-mounted vanities are still going strong. And there are good reasons for that as they make a bathroom look larger. In addition, it’s also easier to keep the floors clean and tidy.

Basin height Australia
You are spoilt for choices when it comes to selecting your wash basin. There is the under-mount sink that will sit at bench height, the above-counter basin and the semi-insert basin just to name a few.
But irrespective of the sink you choose, the top of the basin needs to sit between 860 to 880mm off the floor when you work towards standard bathroom dimensions Australia. This is a convenient height for most adults. You might need to dust off your calculator when you get a custom-made vanity where you pick basin, countertop and cabinet separately. From the overall height of 860 to 880mm deduct the height of your preferred basin, the thickness of your countertop and the targeted air space underneath the vanity which is recommended between 250 and 350mm. The result determines the correct cabinet height.
Tap position for bathroom dimensions Australia

The tap ware sits around 60 to 100mm above the wash basin depending on the shape of the spout. The distance should be big enough to comfortably wash your hands under the outlet, but close enough to avoid excess splashes.
Bathroom mirror height Australia
Mirrors should be installed at eye level of the person who is going to be using the bathroom. A good guideline is for the centre of the mirror to sit between 1,500 and 1,700mm of the floor.

How much space for a toilet Australia
On each side of the toilet you need to allow around 350mm space for the user to sit comfortably. With the width of the toilet pan measuring between 340 and 380mm depending on the model, a good rule of thumb is to allow for 1,000mm altogether. But if space is tight, you can go slightly narrower to 900mm or even 800mm for the total width. If you work towards standard bathroom dimensions Australia and are creating a separate toilet cubicle, aim for a width of 1,000mm minimum. Place the toilet roll holder at around 650mm off of the floor so it can be reached easily.

Bathtub sizes Australia
Bathtubs come in all sorts of shapes and sizes. A generous bathtub measures around 1,800 by 800mm, with its smaller versions measuring 1,700 and 1,500mm in length while their width varies between 750 to 780mm. These are guidelines only as every manufacturer offers different bathtub dimensions. If your space allows, it doesn’t always need to be a standard rectangular shape. What about a soaking tub in a round version? There is for instance a cute one by ABI Interiors with a diametre of only 1,280mm.

When it comes to bathtub types, there is for example the inbuilt or inset bathtub and the popular freestanding tub. The first one is a good choice if you have small children as its lower rim makes it easier to lift a toddler in and out.
For a freestanding bathtub, you wish to allow at least 100mm space all the way around it. This ensures that you can conveniently mop around to keep your bathroom clean.
Towel rail height
A good height to install your towel rail is between 1,600 and 1,800mm. Having said that, if you wish to place two rails on top of each other, consider installing the bottom one at around 1,000 to 1,200mm and the top rail at around 1,800mm. A good height to install a robe hook is between 1,400 and 1,800mm.
