Bathrooms come in all shapes, sizes and layouts, meaning that each and every bathroom renovation throws up its own unique problems.

One of the issues you'll probably have to tackle is where and how to position your bath. So it's no wonder one of the questions we're frequently asked is "What is a standard bath size?".

Whilst things like bathroom plumbing, electrical equipment and heating all come with industry standard sizes, it can often appear that baths do not come with similar standard dimensions. But is this actually true?

What is a standard bath size?

Before the widespread use of the metric system, it was generally accepted that the standard bath size in the UK was 5 foot 6 inches in length. Of course, this now translates as a bath size of 1700mm in length x 700mm in width, which is the most common bath size we sell at

As the average UK bathroom is around 2.3m x 2.7m in size, this would make sense, as it still leaves at least 0.7 metres or 1 metre of clear space, depending on the orientation of your bath.

One important thing to remember when measuring for your straight bath is that tiles may give you a false impression of the space you have available. If you measure from tiled wall to tiled wall, you may have a measurement of, say 1685mm, whereas, in fact, the total space will more than likely be 1700mm.

No matter what type of bath you're installing, whether it's a freestanding tub or a straight bath, find out how to measure correctly with this quick video:

Small baths

Despite there being a standard bath size, you will sometimes find baths or spaces that do not fit with these dimensions. For example, when was approached by the BBC's DIY SOS to help with a project on a family home near Hull, we found that the bath actually measured an incredibly short 1400mm in length. This was so short in fact, we were forced to order a specially constructed bath from one of our suppliers which would fit such a small gap.

Small baths are generally considered to be around 1500mm or 1600mm in length, however, in most cases, the width generally won't deviate from the standard 700mm. If you do have a space as small as this, why not consider a corner bath?

Large baths

At the opposite end of the scale, whilst humans are, on average, getting larger, baths have now increased their proportions, especially in new builds and renovations, resulting in large baths that exceed the standard bath size.

The largest bath we stock is 1800mm in length and up to 850mm wide. That's 5 foot 9 inches, which is just shy of the average height of a male in the UK today. If you have the luxury of space in your bathroom, why not opt for a larger size?
