Introducing RiverMode™, Our Signature Feature:
In still water, your body quickly creates an insulative layer of warm water around the skin—known as your thermal barrier—which reduces the intensity of the cold. RiverMode™ is engineered to eliminate that barrier by creating continuous water movement resulting in true immersion. The result is deeper full-body exposure, and a noticeably more effective cold experience.
Standard RiverMode™: This model features a ¼ HP pump with a flow rate of 25.6 gallons per minute. Dual-Pump RiverMode+™ not available for this model.
Iwaki America Pumps: BlueCube uses Iwaki America pumps featuring magnetically coupled centrifugal pump technology that is nearly silent and industry leading in power and energy efficiency. Chosen for their safety, efficiency, and reputation for extreme durability.
The C1 comes with a powerful 1.5 HP+ commercial chilling motor with precision Japanese compressors, delivering industry-leading cooling performance. Capable of bringing the water down to 37° faster than any cold plunge tub in its class.
