Cold water immersion is no longer a niche recovery tool — it is one of the fastest-growing amenities in luxury wellness, biohacking facilities, and high-performance fitness clubs. Aquatics International Group designs and builds commercial-scale cold plunge and contrast therapy systems with precision temperature control, high-capacity chilling, advanced filtration, and integrated hot/cold circuits. Our systems operate continuously at 39–50°F under heavy commercial use, day after day, without failure.
