What is the approximate height of a built-in bathtub above floor level?

The approximate height of a built-in bathtub above floor level is generally around 16 inches, which aligns with the selected answer. This height is designed to provide comfort for users while maximizing functionality in a bathroom setting. It allows for easy entry and exit from the tub, which is particularly important for safety and accessibility.

When determining the height, considerations include standard plumbing requirements, ergonomic design for users, and the overall aesthetics of the bathroom. A 16-inch height is practical as it accommodates a wide range of body types and allows for sufficient water depth while remaining at a manageable level for users to step over when entering or exiting.

Other options may not reflect typical standards encountered in bathroom design, where practical considerations for user experience play a significant role in determining dimensions.
