What Is the Standard Size of a Bathtub?
The standard size of a bathtub is 60 inches long, 32 inches wide and 18 inches tall. Standard-sized tubs are designed to fit into an alcove, surrounded by three walls. Alcove tubs are available in a wide variety of materials.
A tub or tub-shower combination takes a significant space, especially in a small bathroom. Installing a shower instead of a bathtub helps to increase the remaining space. If space is less limited, larger sizes and styles of tubs are available. When replacing a standard tub with a newer model, many consumers are surprised to learn that a jetted tub requires no more space than the standard tub.
