Traditional hot tubs have not seen much variation as far as the concept is concerned. Generally, hot water is maintained at a comfortable temperature in a small tub in which people tend to spend a long time relaxing. These hot tubs have been made famous in the excessively cold areas of the world, especially the northern hemisphere. The name "hot tub" was originally given to the earliest tubs that were round, made of wood, and located outdoors; now the term is commonly used interchangeably with the phrases "home spa" and "portable spa." However, if one gets more specific, home spas are generally made with a plastic shell; the surrounding cabinet may be made of wood or synthetic materials; and the term can be used to describe an above-ground, in-ground, indoor, or outdoor spa. However, "portable hot tub" is a name for any hot tub/home spa that is pre-assembled and sits above ground; actual size and features of a portable hot tub vary widely, from small portable hot tubs that weigh only a few hundred pounds and plug into a household outlet to large tubs that weigh several thousand pounds and require specific installation methods and electrical wiring.
