Whirlpool tubs
Whirlpool tubs first became popular in America during the 1960s and 70s. A spa or hot tub is also called a "jacuzzi" since the word became a generic after plumbing component manufacturer Jacuzzi introduced the "Spa Whirlpool" in 1968. Air bubbles may be introduced into the nozzles via an air-bleed venturi pump.
