Though once considered only a thing of recreation, hot tubs are more and more being recognized for their therapeutic qualities, and are perhaps more widely used now than they ever were. Many homes now boast a hot tub: either a simple or luxurious model, installed indoors or outdoors.
Hot Tub types
Hot tubs come in several varieties, and depending on the desired look, feel, and use of the tub, one type might be more suitable than others. They range from basic soaking tubs, to spas, to simple bathtub-style hot tubs.
A soaking tub is the oldest form of hot tub (though it's far from being obsolete) and looks a lot like a giant barrel. Compared to other types of hot tubs, it is much deeper and holds more water. However, it possesses little to no circulation properties and while it is very relaxing and luxurious, it generally lacks the jet nozzles that are standard on most newer types of hot tubs.
A spa is what most people have in mind when they think of a hot tub. It's a relatively shallow plastic dish that, in addition to heated water, has jet nozzles with massaging properties. The number of jets will vary depending on the model, as will the property of the jets; some must be adjusted manually, but, for an increase in price, a tub can come with jet nozzles that move automatically. Unlike the average soaking tub, a spa is more versatile in where it can be installed. So long as the area can support the added weight, a spa can be installed anywhere, either outdoors or indoors.
A less obtrusive and certainly more practical version of the hot tub exists in a bathtub-style model. It can be installed like a regular bathtub and, instead of keeping it constantly filled with water, the tub can be filled for each use, like drawing a bath. The major difference between a regular bathtub and one with hot tub properties is that the latter possesses jet nozzles. This allows for the enjoyment of the massaging properties of a hot tub while still having the privacy within the comfort of one's own bathroom.
Installing a hot tub
Setting up a hot tub is a much easier process than most people expect. There is a common misconception that buying a hot tub would mean the installation of complicated plumbing systems to keep the water cycling into and out of the tub. This, however, is not the case, as most new hot tub models are self-sustaining. That means a tub can be filled up, and the same water retained until a change is needed. Chemical treatment can help keep water cleaner for longer, so water changes don't have to become a frequent process.
