Understand The Standard Bath Sizes That Suits Your Bathroom


After a stressful day, people like to take a bath. Throw in bath salts, oils, or bubble baths, you’ve got yourself a relaxing experience just waiting to get underway. But is there space in the bathroom to have one?

In the modern home, they tend to be more of a luxurious item than just the purely functional and space-limited shower recess in a bathroom. There are people who like baths and people who don’t, but no matter what you want to do, the bathroom is where you will find it – it is the only space suitable for it. There are many types of bathtubs when it comes to choosing a bath, not to mention whether to go with enamelled steel or acrylic. There are traditional tubs, clawfoot tubs, soaking tubs, pedestal tubs, and more. You need to decide what type of bathtub is right for you and your bathroom. You could even go the whole hog and get yourself a spa. Spa baths can make a great upgrade to a bathroom if you choose the right one. So there are a lot of factors to consider.

Choosing A Bathtub That Fits

Time to get our head around bathtub dimensions. There is about 3x3m space in a bathroom so you will need to choose a bathtub that fits in that space and leaves space for everything else you need. A small bath tub fixture is perfect for a small bathroom as it doesn’t take up much space and you can still get all the benefits of having a bath. A small bathtub can also be used in a larger bathroom as an extra feature or as a main bath.

If you have a large bathroom then you may want to consider a corner bathtub which takes up less space than a traditional bathtub. Corner bathtubs are perfect for families as they can fit more people in and they look great too.

If you have a very small bathroom then you may want to consider giving up on the idea of an installed or freestanding bath and go with a walk-in shower instead. Walk-in showers are becoming increasingly popular as they don’t take up much space and they’re very easy to use.

When it comes to choosing a bathtub, you need to match your floor space available to the bath dimensions. Sometimes, you may need to select a small bath in terms of the bathtub length you can fit into the bathroom layout. Baths are available in a range of different sizes and forms from freestanding bathtubs to extra deep baths and more.

What is a standard bath size?

This depends on what part of the world you live in, but the people who use baths are pretty much the same everywhere, so everything is pretty similar. A bathtub, or simply a tub, is a large or small container for holding water in which a person or animal may bathe. Standard bathtubs are generally oval in shape and are usually 1700mm in length by 700mm wide with a typical bathroom is around 2.3m x 2.3m. Tubs are usually made of enameled cast-iron, porcelain-on-steel, fiberglass-reinforced polyester, acrylic, and Mass filled with air or water.

What is the Perfect Ratio of Bath To Bathroom Size?

Assuming we are talking about the size of a typical domestic bathroom, the perfect ratio of the bath to bathroom size would be 1:4. This means that for every 1 square meter (1000mm) of bath, there would be 4 square meters (4000mm) of bathroom.

So, for example, if you had a 1500mm square corner bath, you would need a bathroom of at least 6000mm square to achieve the perfect ratio.

Bathtub Sizes Australia

Bath sizes in Australia vary depending on the size of the bathroom. The most common tub size is 180cm, but there are also smaller and larger sizes available. When choosing a bath, it is important to consider the size of the room and how much space you want the tub to take up. If you have a small bathroom, you may want to choose a smaller tub so that it doesn’t overwhelm the space.

Water And Power Consumption

Another consideration, when choosing bath sizes, is the power & water consumed by it. Remember that a “warm” bath means putting in around 65% hot water, so you need to ensure your current hot water system is capable of pumping out this much hot water. You also need to consider the positioning of your home’s plumbing, as you may be up for extra piping infrastructure, especially if the bath is a replacement for an old smaller one.

Some other things to think about when you are trying to decide what size bathtub to get include how much power and water it will use. Keep in mind that a “warm” bath is usually made with around 65% hot water, so you need to make sure your hot water system can handle supplying that much hot water. Another thing to consider is the placement of your home’s plumbing because you may need extra piping if the bathtub is a replacement for an old one.

Freestanding Baths

There is an issue with freestanding bathtubs and the need for adequate clearance around the bath so it can comfortably fit. Bathroom layout ideas can be tricky, but if you have the space for a freestanding bath, make sure you allow adequate clearance around the outside of the tub. If your bathroom is on the small side, consider a corner bathtub.

When it comes to baths, a freestanding bath is seen as one of the more luxurious options that can make a real design statement. It does, however, have benefits and drawbacks.

  • They tend to be larger than other types of baths, so you will have more room to relax in.

Freestanding Bath Cons:

  • They can be quite expensive.
  • They may not be suitable for small bathrooms as they take up a lot of space.

Small Bath Option

The bottom line is that if you have a small space, a small bath will be your only option. Small baths

have their own Pros And Cons.

Small Bath Pros:

  1. Smaller size means less water is needed to fill the tub, making it more environmentally friendly.
  2. The smaller size also makes the tub easier to clean.
  3. Smaller tubs take up less space in your bathroom, making them ideal for small bathrooms.
  4. They can be cheaper than larger tubs since they use less material.
  5. Some people find smaller tubs more comfortable since they fit the contours of their body better.
  6. Smaller tubs may be easier to get in and out of for some people with mobility issues.

And Some Cons:

  1. The size of these tubs may not work for some people. Some people are too tall or large to comfortably take a bath in a smaller tub. 
  2. Small bathtubs tend to be less comfortable than their larger counterparts and may not have all of the features that you want or need.
  3. You cannot fit as many people into your smaller-sized bathtub so if you enjoy baths with company this may not be the best size tub for you
