Chilly GOAT Tubs
Cold plunge tubs by Master Spas with a dedicated commercial program for gyms and studios.
Regions: US
Chilly GOAT Tubs is the cold-plunge line from Master Spas, one of the largest US hot tub manufacturers, co-developed with Michael Phelps and sold with a dedicated commercial program for gyms, fitness centers, wellness spas, and physical therapy clinics. The commercial pitch rests on manufacturing scale: premium insulation, automatic filtration, and the dealer and service network of an established spa manufacturer rather than a venture-backed startup — a real consideration when a broken chiller takes a revenue-producing plunge offline. Multi-unit pricing is available for operators outfitting several locations, though all commercial pricing is quote-based. Confirm throughput and sanitation specs against your expected daily bather load, and compare the total installed cost against purpose-built commercial systems before deciding.
