Bath Sizes (Length, Height & Dimensions)

bath sizes australia

A bath is a container of water, typically large enough for one person to sit in. People often refer to it as a “tub”.

Bathrooms are the room found inside certain buildings where people can go to make use of an apparatus designed for the purpose of laundering the human body with water and soap. Inside this room are fixtures such as sinks, toilets, bidets, showers or baths, toilets etc., which are used together with other waterworks outside the building’s walls. This idea actually goes back into Ancient Rome but was not common until more modern times when plumbing became popularized through industrialization.

This bathroom has a large bath with both a shower and a separate toilet. The suggested bathroom could be around 2.5m×1.8m. This is an example of a small, compact bathroom but it also manages to fit in two things that are commonly found within bathrooms, namely the sink and the toilet/bidet. The latter is actually more common in Europe and Japan, but not so much in the Americas. This bathroom is a good example of a small compact bathroom because it shows how everything can be fitted into a limited space while still being functional.

A freestanding bath (also known in the UK and Australia as a roll-top bath) is a shallow freestanding bath where water depth can be adjusted to suit bathers.

This is not always the case with corner baths since some are actually ‘L’ shaped which means that they can fit into corners where space is less restricted.

People often take a bath to relax after having a stressful day. Some people like baths and others don’t, but whatever you want to do, this bathroom has got it covered. The suggested bathroom size is 3x3m. This bathroom contains both a shower and a tub/bath. One of the main differences between showers and baths is that the latter has a high chance of leaving the bather in a relaxed state (akin to meditation) for between 15 and 30 minutes. People may often buy bath salts, oils or bubble baths from the store, put them in their bathtubs and make the bath even more relaxing.

An inset bath is often the corner part of a bath. The minimum bathroom size for this could be 2.4x2m with a ceiling height of 1.8m and a door width of 90cm. An independently placed bath would not need to take up more than 1/3 of the bathroom space, even less if it were situated in the corner.

Small Bath Sizes

A shower is a common way to take a bath or a shower. A 3×1.8m bathroom is suitable for this kind of bathroom with the minimum ceiling height being 2.2m and a door width of 80cm. The normal size of a simple shower is 900mm x 900mm, but there are larger ones that can take up the same space as a bath.

Bath Length

The average length of a tub is around 170cm but depending on the bathroom layout, it can range anywhere from 150cm to 210cm. Check your design and maybe contact a plumber, and take everything into account when placing tubs of any kind in your brand new bathroom.

Average baths are around 170cm in length and up to 100cm wide. Any bathroom with a space of at least 2.4×2m is suitable for this kind of tubs. It also has a decent price. As always, read your design to see if you really need such a big tub, but in the case that you do, here are some pros and cons. The bigger the baths, the bigger the price.


A large bathtub can be a huge plus for your brand new bathroom. Large tubs may allow more people to get in it at once, which is nice if you have a family or a lot of guests who visit often. Large baths are also easier to wash in, you won’t have to squeeze your legs together as hard as with a small bathtub.


One of the cons is that the water may not fit inside. If this happens, don’t panic, just add some extra hot water from time to time and you’re good to go. Another thing to think about is the price, a bathtub this big may cost a lot more than an average size one. Another con is that you need large amounts of available space for such big tubs. Make sure your hot water system can pump out enough water for a big tub.

Standard Bath Sizes

A freestanding tub is usually made of cast iron, ceramic or stone. A minimum bathroom size for this would be 2.4×2m with a ceiling height of 2.3m and a door width of 90cm. The dimensions are not very important in the case that you have separate shower areas because these tubs are filled when needed by the bather(s) and then emptied again. They don’t need to be as big as other baths because you just fill them up with water and empty them afterwards, but they could still be comfortable enough for the bather to relax in.

A hot water system is an important aspect of your bathroom. You need to have enough capacity for the size of all your bathrooms. For example, if you have a medium bath size in your 3×3m bathroom, you’ll need at least a 12L tank because it takes about 13 minutes to fill up an average tub. However, if you have a larger bath size and your 3×3m bathroom also has a separate shower area, you’ll need at least a 35L tank because the shower may take longer than 13 minutes to fill up.

Standard Bathtub Size

Small bathtubs are the kind of baths that don’t take up too much space. A total bathroom size of 2m W by 3m L is suitable for this kind of tub, with a minimum ceiling height of 2.1m and a door width of 80cm (or 60cm if you’re installing in-between wall units). This specific style looks best when installed to the right or left in your bathroom because it may fit easier in smaller bathrooms.

Bathtub Measurements

Keep in mind that a bathtub could not take up the whole room. If it does, you’re going to have trouble using the shower and all other bathroom appliances.

If your little bathroom is more of a cloakroom with only enough space for a sink or vanity unit and maybe even a toilet, don’t worry because there are small baths available as well. Small-sized baths look good between two wall units where they can be filled from both sides at once or just next to a sink if floor space allows that. It may help if you keep the piping as short as possible and avoid having to cut through studs (particularly between shower and bath areas).

Bathtub Dimensions

A standard tub is around 170 in length, 70 cm in width and averages around 40cm in height. The standard depth is around 50cm which means you’ll be able to fit about 500l of water in it.

Bathtub Length

A small bathtub is one of the best options if you have a tiny bathroom. The tub can be as small as 150cm but anything below that, it’d be problematic to use, so take that into account for next time. Small bathtubs are not only great for small bathrooms, they’re also ideal for young children, elderly people or even people with reduced mobility. They are also often made of acrylic which is the best choice if you want to keep them clean without too much effort.

Standard Bath Size

Remember that baths are made to fit the room they’re being installed in, so measure your space carefully before deciding on a bath size and type. A good way to do this is by drawing up your bathroom on paper, how you do it just depends on the space you have available. If your bathroom is around 5×5m with adequate dimensions, you can have any bathtub of your dreams as long as it doesn’t block access to other important parts of the room.

Standard Bath Height

Remember when measuring your ceiling height that the shower area is part of the building code, so you need to have a space between your ceiling and roof that allows for correct ventilation in case of a leak. This means that you’ll have to install something underneath your ceiling in order to be able to access it.

Standard length tubs are usually around 180cm in length and have a width of around 70cm. The average height can be around 50cm.
