A Short History of Spa Parts Plus (SPP) “The Original Spa Parts Company


  • In 1986 Spa Parts Plus (SPP) was founded by Barry & Paulette Knickerbocker in Riverside, CA and moved to Prescott Valley, AZ in 1991. Barry had been working with Hawkeye Spas when he realized there was demand for replacement spa parts in the portable spa industry. Barry and the SPP team soon discovered they had created a loyal following through sheer hard work, determination, and invaluable industry knowledge in the quest for rare spa parts.
  • In 2012 Spa Parts Plus (SPP) acquired California Specialty Distributors (CSD) which was founded by David & Susan Stern in 1974 in San Luis Obispo, CA which provided access to more spa accessories and an international clientele.
  • In 2019 Spa Parts Plus (SPP) merged with Allied Innovations, an injection molding manufacturer of Len Gordon, Brett Aqualine, and Spa Builder products, and a spa parts wholesale distributor, founded by Len Gordon in 1986 in Las Vegas, NV. This increased the amount of specialized spa parts made available through SPP.
  • In 2024 Spa Parts Plus (SPP) was acquired from Activcarts, a vertically integrated entity to be returned to a wholesale only distributor of spa parts serving the US and International markets by ASPS, a well-established wholesale only spa parts distributor serving the Canadian spa industry. This represents a revival of the “Original Spa Parts Company” to cater and serve the wholesale spa industry trade with friendly service, technical expertise, and unwavering customer care.
