Standard Bathtubs. The two most common tub sizes are 60 inches long by 30 inches wide and 60 inches long by 32 inches wide. A standard rectangular-shaped tub, however, will have a smaller dimensioned bathing well, measuring 55 inches by 24 inches at the top and narrowing to 45 inches by 22 inches at the very bottom. These are general bathtub dimensions for both cast iron and fiberglass tubs.
