Whats 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.
