Dimensions in the chart are external measurements of standard bathtub not actual in tub sizes. Capacity is a factor which defines the interior tub space in gallons. In-side dimensions will vary even comparing the same external tub sizes and will be identified by bathtub shape and style. Some of the free standing bathtubs might have legs which will add another 4” – 5” to the total bathtub height. All sizes in the chart are imperial characteristics of a bathtub length width, and height in inches. The least important number is a bathtub height which does not affect installation much and even for a standard 60”x30” bathtub might vary a couple inches both ways.
