Hot water immersion vessels come in all shapes, sizes, and forms. There are different types of hot water therapy, but most terms are often used interchangeably. When someone refers to a hot tub, spa, or jacuzzi, for example, are they talking about the same thing? What about whirlpools and jetted tubs? They are used for leisure or parties and entertainment. Some of these vessels share similarities, but here’s a look at the difference between hot tubs and spas.
Differences Between Hot Tubs And Spas
Spa
The word “Spa” is often associated with a wellness resort. Spas or day baths are also commercial establishments where people receive aesthetic services such as facials, deep-tissue massages, salt glows, manicures, pedicures, and body wraps, among other services. Since prehistoric times, there has been a belief in the curative powers of mineral water.
However, the spa is also an American term for a hot tub equipped with strong jets that mix air in water for massage purposes. There are two types of spas and hot tubs: portable and in-ground or custom-built.
In-ground or custom styles are referred to as spas. They can be adjacent or attached to an in-ground swimming pool, while others are standalone units, custom-built or set into the ground. Some versions are sturdy, portable models designed to look like custom-built in-ground models that can be positioned on a raised platform. Some hot tubs are custom-built using the same materials as pools, such as fiberglass, gunite, and concrete, and may also include copper and stainless steel. In-ground spas are most likely what you’re going to see at a gym or hotel.
Hot Tub
A hot tub, on the other hand, is more specific in describing a tub with many massaging jets placed strategically. Such an item is typically a small pool of heated water or a large tub used for hydrotherapy or pleasure. As such, the term “hot tub” is often used to refer to an above-ground portable spa. While there are a wide variety of accessories for hot tubs, all the components, including the electrical system and plumbing, are built inside the tub. A hot tub is usually filled with a garden hose and can be drained anytime or relocated to your new premises when you move.
Hot tubs range from simple models with a few jets to sophisticated acrylic shells with a high jet count. Hot tubs have advanced significantly since their inception as rounded redwood vessels. Today’s hot tubs are highly sophisticated and generally offer a much better experience than in-ground spas because they’re easier to care for, more energy-efficient, more comfortable, and provide better massage and hot tub therapy for you and your family. It helps in reducing stress and anxiety when needed.
Portable models can be designed to accommodate anywhere from two to eight or more occupants. They can be made of cheap materials like vinyl or latex or plastics like polyethylene, fiberglass, or acrylic. Some hot tubs are built with recycled materials such as barrels or metal bins, while others are made from traditional wood.
Bottom Line
There sure are plenty of different terms to describe hot water immersion vessels. The pointers should provide some clarification on the similarities and differences between hot tubs and spas. Traditional hot tubs are made of wood, whereas spas can be portable or adjacent to an in-ground swimming pool, while others are standalone units, custom-built, or set into the ground.
