International Hot Tub

What International Hot Tub does

International Hot Tub (legal name: International Hot Tub Company, dba IHT Hot Tubs & Fireplaces) is a specialty retailer established in 1978 and headquartered in Denver, Colorado. The company operates four retail showrooms across the Denver metro and Boulder area—Denver I-25 at 8th Ave (1035 Zuni St), Denver Broadway (4275 N Broadway A), Boulder (3550 Arapahoe Ave), and Highlands Ranch (2660 E County Line Rd, Littleton)—selling premium hot tubs (Hot Spring, Caldera, Freeflow Spas), Endless Pools swim spas, Tylo infrared saunas, cold plunges, and fireplaces from brands including Kozy Heat, Majestic, Osburn, and Valcourt. IHT is an authorized dealer rather than a manufacturer, pairing product sales with an in-house (non-subcontracted) service and repair organization, an inventory of spare parts, approved electrical and gas installation contractors, and financing through Wells Fargo and 1st Security Bank with terms of 12 to 144 months.

The company's go-to-market is direct-to-consumer and omnichannel: in-store test soaks, swims, and sauna sessions; free in-home consultations for site evaluation; Buy From Home virtual tours; a $100 gift certificate referral program; promotional campaigns (e.g., up to $2,000 off hot tubs, $5,000 instant rebate on swim spas); and a Costco visibility partnership. Revenue is generated across multiple streams—one-time hardware sales (Product Sales), recurring managed services (Silver/Gold/Platinum Valet Water Care plans with weekly to quarterly cadence), subscription delivery (Autoship for SilkBalance and silver ion cartridges), trade-in transactions, and professional repair/warranty service—giving the business a mix of transactional and contracted revenue on its installed base.

Ownership history: founded 1978 as a family-owned business, acquired by the Hiner family in 2005, and acquired by Leslie's Poolmart, Inc. in 2021, making IHT a subsidiary within one of the nation's largest specialty pool and spa retailers. The company holds an A+ Better Business Bureau rating maintained since 1999, has been an eight-time Watkins Wellness Territory Dealer of the Year and National Dealer of the Year, and is an AQUA 100 Hall of Fame inductee. The technology stack is a standard e-commerce and CMS platform (ihtspas.com) with an adjacent e-commerce store at denverhottubsupplies.com; there is no proprietary software platform, API, or AI/ML capability disclosed.
