What's the difference between a Hot Tub and a Spa?

The term "Hot Tub" originally referred to the wooden, barrel-shaped tubs, which became popular in the late 1960s. Early hot tubs were fairly simple devices, which basically held hot water and had enough room for one or two bathers at a time. When the industry began building tubs of molded fiberglass or with thermoplastic shells, they were given the tag "spa" to differentiate them from their wooden cousins. The wooden hot tub has evolved over time to include such amenities as seating, jets, filters, and most of the features associated with a spa. In fact, the phrase "hot tubbing" can be taken to mean soaking in either type of vessel.

How do I find a quality brand of spa?

Take the time to look at various brands. Ask about warranties. Quality products will carry ironclad warranties against defects that will cover the shell, motors and control units. Reputable manufacturers will will not be shy about disclosing specifications. Check for either the ETL or UL rating. "Look under the hood." We cannot stress this enough. If the workmanship inside the access door of the spa looks shoddy, this tells you a lot about what you cannot see. In these time of rising energy costs, insist on a spa cabinet that is full-foamed, and has other energy saving features. Make sure the spa has 2x4 framing, not 2x2.
