A there are 4 main bath tubs groups: alcove bath tubs, corners tubs, walk-in and freestanding bath tubs. The average bathtub measurements of the wall to wall bath are as follows. The length is 60″, the width is 30″-32″ and the height is 17″-20″. Smaller and larger variants are not as wide spread as 60″x32″x17″ bath tub dimensions, but also exist. The longest standard bath tub is 72″, while she shortest is 48 inch long.
The standard bathtub height varies from 14″ to 25″. The corner bath tubs differ a bit in their dimensions. They have 2 sides of the same length- 48″, 60″ and 72″ and height of 19″, 24″ and 20″. Most of free standing bath tubs have 60 inch in length and 20″26″ in height. The walk-in bath tubs are always tall (38″), but their length does not differ from the other bath tubs types: 48″ and 60″. The standard tub spout height is 4-6 inch above the apron top.
