A history made by innovation
In the 1980s, David Ludlow, the son of a pool builder, had convinced his father to start selling hot tubs as popularity increased. However, a condition of doing so meant he would have to take every service call. This lead to the eventual repair of many leaks and malfunctions. There had to be a better way to engineer a more reliable spa. Dave, who would go on to found Bullfrog Spas, set his mind to innovative problem solving, a spirit we’ve had in our DNA ever since.
Dave imagined a hot tub with modular jetted seat backs that would contain the jets and the bulk of the spa’s plumbing. This design placed most of the hoses and fittings inside the spa’s main body of water. If they happened to eventually develop a small leak, it wouldn’t affect performance or require costly repairs. These seat-back jet arrays would become what’s know today as the JetPak. By 1997, Bullfrog Spas secured the first 6 of many patents to come.
Many more innovations in reliability and performance have come about since, leading to dozens of patents. Our legacy of innovation pales in comparison to the potential of our future. Watch as Bullfrog Spas continues to invent, design, engineer, and improve products and experiences that create peaceful lives.
