What is a JetPak? JetPaks are modular jetted seat backs that can be moved and interchanged between other JetPak-ready seats in your Bullfrog Spa.* JetPaks may be interchanged in under one minute to quickly address your personal massage needs. This revolutionary modular technology is hailed by experts as the most significant advancement in home spas since the invention of the portable hot tub. This means JetPaks are Customizable – Design your spa to perfectly suit your needs, with the jetting choices and the arrangement that works best for you.
