Hot Tub is typically used to refer to an above-ground portable spa. A hot tub or portable spa is a completely self-contained vessel. All of the plumbing, as well as the electrical control system and other components, are built inside the hot tub cabinet. This means that there is no plumbing required. A hot tub is filled with a garden hose, can be drained anytime, and can even be relocated to a new home if you move.
One of the best thing about hot tubs is their ability to hold a set temperature. Thanks to advancements in technology, you can set a selected temperature and expect your hot tub to be hot and ready to use anytime you are. There is no need to wait for the hot tub to heat up.
Hot tubs can range from very simple designs with a few jets to intricate acrylic shells with an extremely high jet count. Hot tubs today have come a long way from the round redwood vessels of the past, and generally offer a much better experience than in-ground spas because they are more comfortable, more energy efficient,esaier to care for , and provide better massage.
