The idea of immersing in a deep and relaxing bathtub evokes the image of steam rising from an exotic spa, but the experience can be recreated in a bathtub at home. But what exactly is a bathtub? There are no hard and fast rules about the composition of a bathtub, but water depth is the main feature to consider.
The bathtub has an overflow function that prevents water from accidentally overflowing the bathtub and causing flooding. Therefore, even if the tub is as full as possible, it will not be completely covered. Rather than simply measuring the depth of the tub from the bottom to the rim, the depth of the tub, you can go a step further and ask how deep the water is from the inner bottom to the overflow of a particular tub. A special overflow drain can be used to close the overflow and get deeper water into regular tubs. Be careful not to flood the bathtub!
So how deep is the bathtub? Remember the water depth measurements. Aim for at least 14 to 15 inches of water. This level should be deep enough to cover most of a person's frame. Some tanks, such as Japanese immersion tanks, offer depths over 22 inches. You might think the deeper the better, but first, make sure your home and lifestyle are compatible with the tub.
