A standard alcove bathtub works in most bathrooms and usually measures around 60-inches long, 30-inches wide, and 14-18 inches deep. Since the bathtub size is closely related to the size of your bathroom, it should not be too small to accommodate your needs or too large to obstruct movement.

With that in mind, let us check out the standard bathtub dimensions that are right for your space and the type of bathtub you can invest in to create a unique-looking bathroom to make your cleanup experience wholesome and relaxing.
