How Much Water Does a Bathtub Hold?

Whether you are remodeling your bathroom or building it from scratch, there's something that matters more than the style and outlook of your bathroom. While the design and appearance of the tub make your bathroom look more attractive, it doesn't promise the functionality or longevity you'd want from a bathroom fixture.

Why Knowing the Bathtub Water Capacity is Important?

Knowing the amount of water your bathtub can hold may not be as important for most homeowners. It is fundamental for every bathroom build and renovation. Bathtubs can be heavy, especially when they are filled to the brim adding extensive pressure on the flooring. A standard bathtub with a 100-gallon capacity will exert a load of 800 pounds on the floor, excluding your own and the bathtub's weight.

What makes the information even more vital is the environmental aspect. Bathing in a bathtub usually requires more water than taking a shower, thus hurting the natural water reservoirs underground. As we move toward environmentally friendly living, people are getting more conscious about excessive water usage through a bathtub. Many have preferred installing a relatively smaller bathtub in their rooms to cope with the current circumstances.

If you are one with a similar ideology and preferences, you might be wondering how much water a bathtub holds. And that leaves us with four common types of bathtubs and their water capacity.
