What is the capacity of a tub measured in gallons?

The capacity of a tub can vary significantly depending on its design and size, but most standard bathtubs typically hold between 40 to 80 gallons of water when filled to capacity. Larger soaking tubs or whirlpool tubs can hold even more, often exceeding 100 gallons. It’s important to check the specifications of a specific tub model for its exact capacity.
