Are you installing a new bathroom with a nice new bath? You may be wondering “What is the standard bath height?” Hmmm, it’s a question that many people ask, and it’s an important one. The height of your bath is an important consideration, not only for comfort and safety but also because it can be the make-or-break factor in making a bathroom feel cosy. In this article, we’ll explore the idea of a standard bath height, as well as share a link to some products that might work for your home!

Standard Bath

What is the Standard UK Bath Height?

In the UK, the standard bath height is 510mm, although there are no industry regulations regarding a standard bath height in the UK, this is an unofficial standard, and is by far, the most common. If you are prepared to have a custom side panel made, you can have your bath at almost any height you wish providing there is clearance for the waste pipe underneath.

What is the Standard UK Bath Length?

The ‘standard’ and most common bath length in the UK is 1700mm. This is not governed by any regulation; it is just the most regularly used length. There are baths available that are shorter than this (1400mm) and baths that are much longer at 2000mm, but these are rarely found in the UK.

Often the largest and deepest bathtubs are freestanding as they are not required to fit neatly against walls or into alcoves.

What is the Standard UK Bath Width?

In the UK, the most common bathtub width is 700mm but again this is not a true ‘official’ standard due to the flexibility we now see in shape and design. Baths these days come in all sorts of shapes and sizes to fit the space you have available.

What is the Standard UK Bath Depth?

Different baths vary but the most common depth of a bath in the UK is 250mm. Again, this is not ‘standard’ as such but the most common.

Note: This measurement is from the waste to the bottom of the overflow.


Although there are no official standard bath dimensions in the UK, the most common is 1700 x 700 x 510mm. Looking for a New Bath?
