How to build a hot tub was recorded at the Bullfrog manufacturing facility in Bluffdale Utah. This step by step process is detailed by Bill Renter from Long Island Hot Tub "Hot Tub Expert" to show the newest technology in the Hot Tub industry. The newest innovation is the revolutionary new H2AIR Jet Pak, which reduces the pluming in the spa by 90%. This means more powerful jets, more energy efficient, less possibility of leaks, and the ability to change or add more or different jets to your spa.
