ThermoSpas

What ThermoSpas does

ThermoSpas Hot Tub Products, Inc. is a privately held US manufacturer and direct-to-consumer retailer of hot tubs, swim spas, and aftermarket spa care products. Founded in 1983 as a spa manufacturer, the company pivoted to a direct-to-consumer business model in 1995 and is headquartered in Irvine, California, with 51–100 full-time employees distributed nationwide and a field network of in-home service technicians.

The company's product portfolio centers on the ClearRay branded water care line (chlorinating granules, oxidizing shock, pH/alkalinity balancers, filter cleaner, stain and scale preventer, water clarifier, foam away, jet line cleaner), proprietary sanitization hardware (ThermoClear EPA-Approved mineral cartridges replaced every four months at $39.99, FROG @ease SmartChlor systems, dual-voltage ThermOzone corona discharge ozone generators), replacement filters, R-16 rated ThermoCover replacement covers, accessories (steps, safety rails, replacement pillows), and water testing consumables. Differentiated technical features include 20% better filtration efficiency versus standard filters, twice-industry-standard 2 lb foam density and 60% more efficient R-16 insulation on covers, and an Arthritis Foundation Ease of Use Commendation on the ThermoCover.

ThermoSpas generates revenue through a single-country, US-only DTC channel stack: a 24/7 e-commerce storefront (online.thermospas.com), phone-based inside sales (800-876-0158 / 888-743-8121), and a national in-home service technician network for repairs, drain/refill, openings/closings, and warranty work. Pricing is unit-based across chemicals, replacement parts, and accessories, with recurring-revenue consumables (filters, cartridges, test strips, sanitizers) layered on top of one-time hardware sales. The customer base consists of individual hot tub and swim spa owners, with no named B2B or enterprise accounts disclosed.
