The BlueCube C3 Cold Plunge Tub is designed for indoor and outdoor installation and comes in 2 interior length configurations. The tub is constructed from marine-grade 316-L stainless steel with a 14-gauge thickness, and features a contoured interior at a 20-degree slope.
The exterior is finished with Line-X® weatherproof coating and is available in 4 standard colors or any Sherwin-Williams custom color. A handcrafted wooden side deck is included for entry, with wood options like walnut, mahogany, white oak, white maple, and cherry.
RiverMode™ Plus — a dual-pump system using 2 Iwaki America magnetically coupled pumps — delivers continuous water movement to disrupt the thermal layer that forms around the body in still water.
Filtration runs through a 20-micron system, and automatic ozone sanitization handles pathogen and contaminant control without relying on added chemicals. The unit ships fully assembled, operates on a standard dedicated outlet, and is controlled via iOS and Android app.
A commercial upgrade package is available that adds AOP or chlorine drip sanitation, an integrated skimmer, and DOH compliance documentation.
