The Pool & Hot Tub Alliance is a 501(c)(6) nonprofit trade association that has supported the pool, hot tub, and spa industry since 1956, representing 4,000 members worldwide across manufacturers, builders, retailers, service companies, distributors, commercial facilities, and professional affiliates. PHTA provides education and certification (including the Certified Pool & Spa Operator program and GENESIS design/engineering/construction training), standards development (ANSI/PHTA standards for pools and spas), government advocacy at the federal, state, and local level, market research, and industry events including the Pool | Spa | Patio Expo and the MasterMind Summit. Hot tub dealers can join through PHTA’s IHTA division for category-specific benefits, or as part of general PHTA retailer membership.

IHTA is the dedicated trade organization for hot tub and swim spa dealers, giving them a direct network of manufacturers, retailers, and suppliers built specifically around their category. Membership includes a free Certified Hot Tub Technician (CHTT) course each year, helping dealers validate technician expertise and stand out in the service market. Dealers get free, on-demand training through PHTA Class Pass covering topics like customer service and water chemistry, plus discounted enrollment in Retail Professional 101 to sharpen sales skills. IHTA also runs advocacy specific to hot tub dealers at the local, state, and federal level, provides access to ANSI-accredited safety and energy standards for hot tubs, and issues regulatory alerts and compliance updates so dealers stay ahead of code changes. Members can post unlimited job listings on the Work in Aquatics job board, receive one free industry standard PDF per year, and are eligible for recognition as IHTA Retailer of the Year. IHTA also negotiates member discounts on liability insurance, POS systems, marketing tools, and inventory management software, and runs marketing and public awareness campaigns that promote hot tub ownership to consumers.
