This is the industry standard. Can we say "state of the art"? Forget the brand name toy hot tub and spas you see advertised that move water around and have a variety of gimmicks. Here are the facts. Those tiny jets and annoying spinning jets do nothing for your health and often hurt. This is true hydrotherapy...large jets giving you a real deep massage every time you use it. These tubs are deep soakers for the Japanese health club experience. And speaking of health clubs, you won't find a better tub there, in fact these tubs are most commonly used. Once again creme de la creme plan on passing it on to the next generation because when spas are built right they are bulletproof. I know government buildings that have these spas, billionaire health clubs and five star hotels. Quality, service and the special satisfaction knowing that your bought the best spa ever made.
