SPA:

According to wikipedia; a Spa is a term associated with water treatment ~ also known as balneotherapy. Spa resorts (including natural hot springs) typically offer various forms of hydrotherapy.

The belief in the curative powers of mineral waters goes back to prehistoric times. Popular worldwide, but are especially loved in Europe and Japan. Day spas are also quite popular in the U.S..

But a spa is also used to refer to the American term for a hot tub that is equipped with strong jets which mix air into the water for a more pronounced massage effect. They can be above ground, like one of our portable spas shown here, or they can be sunk into an indoor floor or outdoor deck, or be a small part of an inground swimming pool, known as a pool and spa combo.

HOT TUB:

According to wikipedia: a Hot Tub is a large tub or small pool full of heated water and used for hydrotherapy or pleasure. Some have jets for massage purposes. Hot tubs are sometimes also known as spas.

A perfect example of the confusion that exists – a hot tub to me, is not a spa. A hot tub is a wooden tub, first of all. If you are talking about a swirly, acryclic finish with molded seats and a million jets, that’s a spa.

A hot tub is a (usually) round wooden tank, with a simple bench seat, and 4-8 jets around the side. Blowers and high speed pumps? Not in my hot tub, thank you. To me, a hot tub is a hot soak, without noisy equipment and turbulent bubbles bouncing me off the seat.
