Bathtub Sizes in Australia: A Comprehensive Guide

When it comes to designing or renovating your bathroom, choosing the right bathtub size is crucial. A bathtub that is too small can be uncomfortable, while a bathtub that is too large can take up too much space. In Australia, standard bathtub sizes vary depending on the type of bathtub and the manufacturer.

Typically, the standard size of a built-in bathtub in Australia is around 1500mm to 1700mm in length and 700mm to 750mm in width. However, larger bathtubs are becoming more common and are available for those who want a more spacious bathing experience. Keep in mind that if you are over 180cm tall, the standard size bathtub may be uncomfortable for you.

When choosing a bathtub size, it is important to consider the size of your bathroom and your personal preferences. A smaller bathroom may require a bathtub that is more compact, while a larger bathroom can accommodate a larger bathtub. Additionally, if you enjoy soaking in the bathtub, you may want to opt for a larger size to ensure maximum comfort. Overall, selecting the right bathtub size can enhance your bathroom experience and add value to your home.

Understanding Bathtub Sizes

When it comes to choosing a bathtub for your bathroom, the size is an important factor to consider. Choosing the right size can ensure that your bathtub fits perfectly in your bathroom and provides you with the comfort and relaxation you need after a long day. Here’s what you need to know about bathtub sizes in Australia.

Standard Bathtub Size

The standard bathtub size in Australia is 1700mm in length, 750mm in width, and 550mm in height. This size is suitable for most bathrooms, and you can find a wide range of styles and designs in this size. However, if you have a larger bathroom, you may want to consider a bigger bathtub for added comfort.

Common Bathtub Sizes

Apart from the standard bathtub sizes, there are other common bathtub sizes that you can choose from. Here are a few examples:

• Small Bathtubs: Small bathtubs are typically 1200mm in length and 700mm in width, making them perfect for small bathrooms or ensuite bathrooms.
• Large Bathtubs: Large bathtubs can be 1800mm or longer in length and 800mm or wider in width, providing ample space for a luxurious soak.

Bathtub Size Considerations

When choosing a bathtub size, there are a few factors to consider. These include:

• Bathroom Size: The size of your bathroom will determine the maximum size of the bathtub you can install. A small bathroom may not be able to accommodate a large bathtub, while a larger bathroom can accommodate a variety of sizes.
• Water Usage: A larger bathtub will require more water to fill, which can increase your water usage and bills.
• Comfort: Choosing the right size bathtub can ensure that you are comfortable while soaking. A bathtub that is too small can be cramped, while a bathtub that is too large can be uncomfortable to use.

Types of Bathtubs in Australia

When it comes to choosing a bathtub in Australia, there are several types to consider. Each type has its own advantages and disadvantages, so it’s important to know what you’re looking for before making a purchase.

Freestanding Bathtubs

Freestanding bathtubs are a popular option for those looking to make a statement in their bathroom. They are not attached to any walls and can be placed anywhere in the room. They come in a variety of shapes and sizes, from classic clawfoot tubs to modern, geometric designs. However, they do require more space than other types of bathtubs and can be more expensive.

Inset Baths

Inset baths, also known as alcove baths, are the most common type of bathtub in Australia. They are installed between three walls and are a great option for those with limited space. They come in a range of sizes, from small to large, and can be made from a variety of materials.

Built-in Baths

Built-in baths are similar to inset baths, but they are not enclosed on all sides. They are typically installed against one wall and are a great option for those who want a bathtub but don’t have a lot of space. They come in a range of bathtub sizes and can be made from a variety of materials.

Corner Baths

Corner baths are designed to fit into the corner of a room, making them a great option for those with limited space. They come in a variety of sizes and shapes, from triangular to rectangular, and can be made from a variety of materials.

Soaking Tubs

Soaking tubs are deeper than standard bathtubs and are designed to provide a more immersive bathing experience. They come in a variety of shapes and sizes and can be made from a variety of materials. They are a great option for those who want to relax and unwind after a long day.

Compact Baths

Compact baths are designed for small bathrooms and are typically shorter and narrower than standard bathtubs. They come in a range of shapes and sizes and can be made from a variety of materials. They are a great option for those who want a bathtub but don’t have a lot of space.

Drop-in Baths

Drop-in baths, also known as platform tubs, are a space-saving option made for smaller bathrooms and ensuites. They are installed on a platform that fits against the wall and sits on top of the floor. This makes them movable for when you move house or renovate your bathroom.

Bathtub Dimensions and Space Considerations

When it comes to choosing a bathtub for your bathroom, there are a few factors to consider, such as the size of your bathroom and the available floor space. In Australia, standard bath sizes range from small to large, with dimensions varying depending on the size of the tub.

A small bath is typically considered one that measures 1400mm in length and 600mm in width, while an average bath is approximately 1700mm in length and 700mm in width. A large bath is 1800mm in length and 800mm in width and above. These dimensions can vary slightly depending on the manufacturer.

It’s important to consider the dimensions of the bathtub in relation to the size of your bathroom. If you have a compact or small bathroom, a smaller bathtub may be a more practical option. On the other hand, if you have a large bathroom, a larger bathtub may be a better fit.

Another consideration is the height of the bathtub. The standard height, or depth, of a built-in bathtub in Australia is about 380mm, while freestanding baths can be deeper, with grand claw-foot baths reaching up to 600mm or more.

When planning your bathroom layout, it’s important to take into account the space required for the bathtub, as well as any additional fixtures such as a shower or vanity. You’ll want to ensure that there is enough space to comfortably access and use the bathtub, without it feeling cramped or overcrowded.

Installation and Plumbing Requirements

When it comes to installing a bathtub in your bathroom, there are a few things you need to consider. Here are some installation and plumbing requirements to keep in mind:

Water Supply

Firstly, you need to ensure that there is a water supply available near the location where you want to install the bathtub. The water supply should be able to provide enough water pressure to fill the bathtub quickly. If you’re unsure about the water pressure in your home, you can contact a plumber to check it for you.

Plumbing and Piping

You’ll need to have plumbing and piping installed to connect the bathtub to the water supply and drain. The plumbing and piping should be installed according to the relevant Australian standards. It’s important to ensure that the plumbing and piping are installed correctly to avoid any leaks or other issues.

Taps

You’ll also need to choose the right taps for your bathtub. There are different types of taps available, including mixer taps, which combine hot and cold water, and separate hot and cold taps. Make sure that the taps you choose are compatible with the plumbing and piping in your bathroom.

Tank

If you’re installing a freestanding bathtub, you may need to install a tank to provide enough water pressure to fill the bathtub. The tank should be installed according to the relevant Australian standards and should be able to provide enough water pressure to fill the bathtub quickly.

Material Choices for Bathtubs

When choosing a bathtub, one of the most important factors to consider is the material it is made from. Bathtubs are available in various materials, including acrylic, cast iron, pressed metal, and natural stone. Each material has its own advantages and disadvantages, so it is important to choose the one that best fits your needs.

Acrylic

Acrylic is a popular choice for bathtubs in Australia due to its lightweight and affordable nature. It is a type of plastic that is reinforced with fiberglass, making it durable and easy to maintain. Acrylic bathtubs are available in a wide range of colours and styles, making it easy to find one that matches your bathroom decor.

One of the main advantages of acrylic bathtubs is that they are easy to install. They are lightweight, which means they can be installed on any level of a house without the need for additional support. Acrylic is also a good insulator, which means that the water in the bathtub will stay warm for longer.

Cast Iron

Cast iron bathtubs are known for their durability and classic look. They are made by pouring molten iron into a mould, which creates a solid and heavy bathtub. Cast iron bathtubs are available in a variety of styles, including clawfoot and freestanding.

One of the main advantages of cast iron bathtubs is their durability. They are resistant to scratches and chips, and they can last for many years with proper maintenance. Cast iron is also a good insulator, which means that the water in the bathtub will stay warm for longer.

Natural Stone

Natural stone bathtubs are a luxurious choice for bathrooms. They are made from a variety of materials, including marble, granite, and travertine. Natural stone bathtubs are available in a variety of colours and styles, making it easy to find one that matches your bathroom decor.

One of the main advantages of natural stone bathtubs is their unique and luxurious look. They are also incredibly durable and can last for many years with proper maintenance. However, they are also the most expensive type of bathtub, and they require special care to prevent damage.

Pressed Metal

Pressed metal bathtubs are a popular choice for those who want a vintage or retro look in their bathroom. They are made from sheets of metal that are pressed into shape, creating a lightweight and durable bathtub. Pressed metal bathtubs are available in a variety of styles, including clawfoot and freestanding.

One of the main advantages of pressed metal bathtubs is their lightweight nature. They can be installed on any level of a house without the need for additional support. Pressed metal is also a good insulator, which means that the water in the bathtub will stay warm for longer.

Comfort and Personal Preferences

When it comes to choosing a bathtub, comfort and personal preferences are important factors to consider. After all, you want to enjoy your bath time and feel relaxed and comfortable. Here are some things to keep in mind.

Shape and Size

The shape and size of your bathtub can greatly affect your comfort level. Some people prefer a deep and narrow soaking tub, while others prefer a wider and shallower tub. You should also consider the shape of the tub. Rectangular tubs are the most common, but oval and round tubs can offer a unique and comfortable experience.

Shower or Soaking Tub

Another important factor to consider is whether you want a shower and bathtub combination or a standalone soaking tub. If you prefer to take quick showers, a shower and bathtub combination may be the best option for you. However, if you enjoy long and relaxing baths, a standalone soaking tub may be a better choice.

Hot Water System

Your hot water system can also affect your comfort level. If you have a small hot water system, you may need to choose a smaller bathtub or consider upgrading your hot water system to accommodate a larger tub.

Personal Preferences

Everyone has their own personal preferences when it comes to bathtub size and shape. Some people prefer a larger bathtub for extra comfort, while others prefer a smaller bathtub to save space. You should also consider your age and mobility. Elderly individuals may prefer a bathtub with easy access and safety features.

Measurements and Fixtures

When choosing a bathtub, it’s important to take accurate measurements of your bathroom to ensure the tub will fit properly. You should also consider the fixtures you want, such as a built-in or freestanding tub. Built-in tubs are typically the most popular choice, but freestanding tubs can offer a unique and stylish look to your bathroom.
