What is the Most Common Standard Bathtub Size?

The most common standard bathtub size in Australia is 1700mm in length, 750mm in width, and 550mm in height, which is suitable for most bathroom sizes, making it a popular option for homeowners.

The 1700mm length is long enough for most people to stretch out comfortably while bathing, and the 750mm width provides ample space for movement. The height of 550mm is a comfortable depth for soaking and ensures that the water does not overflow. Additionally, this standard size is readily available in a range of styles and materials, making it easy for homeowners to find a bathtub that fits their design preferences and budget.

If you’re looking for a bathtub that will provide you with a calming soak after a long day, the standard bath size should do the trick. Of course, there are variations in size, and some people prefer bigger or smaller tubs. Find more bathtub sizes in the next section.

Typical Bathtub Sizes

To ensure that you get the right fit, we take an in-depth look at four typical bathtub dimensions in Australia, so you can confidently maximize the space and design aesthetic when purchasing your new tub.

Freestanding Bath Dimensions

The freestanding bath is becoming an increasingly popular choice, providing a stylish and luxurious centerpiece to any bathroom. Generally, freestanding bathtubs tend to be larger than traditional built-in bathtubs. The most common size range for a freestanding bathtub in Australia is between 1500mm to 1800mm in length, and 700mm to 800mm in width. It’s also important to keep in mind the height, and the standard bath height ranges between 600mm and 700mm. 

It’s essential to consider the size of the bathroom and the space available when selecting a freestanding bathtub, as they can take up a significant amount of floor space. Additionally, the size of the bathtub can impact the amount of water required to fill it, and homeowners may need to upgrade their water heating system to accommodate for this.

Back-to-Wall Bath Dimensions

The back-to-wall bathtub is a popular option in Australia as it provides the look of a freestanding bathtub but can be installed against a wall, saving space. The typical size of a back-to-wall bathtub in Australia is slightly smaller than a freestanding bathtub, with a length of around 1500mm to 1700mm, a width of 700mm to 800mm, and a height of 600mm to 700mm.

It’s important to note that back-to-wall bathtubs require a wall to be installed against, which means that the bathroom layout and design will need to be taken into consideration when selecting a back-to-wall bathtub. In addition, the installation process can be more complicated than that of a freestanding bathtub, so it’s recommended to seek the advice of a professional plumber or builder.

Corner Bath Dimensions

The corner bathtub is also an excellent choice for those who want to maximize space in their bathroom while still enjoying a relaxing soak. The typical corner bathtub measurements in Australia can vary depending on the brand and model. Generally, the bath length ranges from 1300mm to 1500mm, the width from 1300mm to 1500mm, and the height from 500mm to 600mm.

The corner design allows the bathtub to be positioned in the corner of the room, which saves space and provides a unique look. Thus, you should consider the dimensions of the space where the bathtub will be installed, including the height of the walls and any adjacent fixtures or furniture. This can help ensure that the bathtub fits snugly in the corner and allows for safe entry and exit. 

Drop-In Bath Dimensions

The drop-in bathtub, also known as the built-in bathtub, is very common in Australian homes as it offers a versatile and customizable design. However, drop-in bathtubs tend to be smaller than freestanding and corner bathtubs. The most common size range for a drop-in bathtub is between 1200mm to 1700mm in length, 700mm to 800mm in width, and 400mm to 500mm in height.

Drop-in bathtubs are designed to be installed into a frame or structure built into the bathroom floor and can be customized to fit the available space. Therefore, it’s vital to ensure that the drop-in bathtub fits comfortably in the space provided, and that the bathtub is level and securely fastened to the frame to prevent any movement or instability.

Conclusion

After knowing the standard bathtub size and four typical bathtub sizes, selecting a satisfying bathtub is no longer a difficult task. And remember that when remodeling or installing a new bathtub, consider checking the available space and other standards to ensure you meet any necessary requirements. We hope this comprehensive guide on standard bath tub sizes provides you insight and helps you choose the perfect tub for your bathroom!

FAQ

Can two people fit in a standard tub?

Technically, two people can fit in a standard tub, but it may not be the most comfortable experience. Standard tubs are designed to accommodate one person comfortably, and adding a second person can be a tight fit, especially for larger individuals. Additionally, filling a standard tub with enough water to cover two people may require more water than the tub can hold, making it challenging to keep the water at a comfortable temperature. A two-person bathtub should be greater than 1700mm long, 800mm wide, and 600mm tall.

What is a good depth for a soaking tub?

A good depth for a soaking tub is generally around 300mm to 400mm. This depth allows for enough water to cover the bather’s entire body and provides a comfortable and relaxing soak. However, the depth of a soaking tub can also depend on personal preferences, and some people may prefer a deeper or shallower tub.

How much space should I have in front of my tub?

The amount of space you should have in front of your tub depends on the specific type and model of the bathtub you have. For example, a freestanding bathtub typically requires more space than a built-in bathtub. Generally, it’s recommended to have at least 30 inches (76cm) of clear floor space in front of the tub to ensure safe entry and exit. This space should be free from any obstacles or furniture that could cause accidents or make it difficult to maneuver.
