For over 40 years L.A. Spas has a rich history of innovation. The company was an early pioneer in utilizing modern day spa manufacturing techniques, including vacuum forming spa shells from acrylic, utilizing vinyl ester resin to strengthen the spa shell, developing “Reverse Mold Technology” (RMT), recessing therapy jets, and integrating fiber optic lighting and audio systems for mood and style. All of these elements lead to the development of the modern day “hot tub” or “spa.” In 2003, L.A. Spas solidified its position as the leader in filtration technology by developing its patented Aqua Klean® filters. These innovations forever changed hydrotherapy.
