Creating a relaxing space requires knowledge of bathtub dimensions: style, pros and cons, and how it will affect your space.

What are average bathtub dimensions?

The most common type of tub is the alcove tub, which also serves as a shower. This is a great space-saving option for those who want access to both a bath and shower. The average size of these style tub is 60″x32″ although of course they come in all sizes.

Those over 6ft will want to choose one oversized tub averaging 72″x42″x23″ in size. If you’re going for an oversized tub, go for at least 70″ in length.

Oversized soaker tub dimensions

If you are a taller person, an oversized bathtub is a fantastic choice. For example, The dimensions of the TOTO Aimes Soaker Bathtub are approximately 71″x36″x24″. The average tub is around 60 inches, which means this tub is also suitable for taller individuals.
