Description

The BlueCube D1 Cold Plunge Tub is a compact, upright unit designed for full-body immersion up to the neck, with a contoured interior intended to support natural body alignment during use. The proprietary RiverMode™ circulation system uses an Iwaki America magnetically coupled centrifugal pump to maintain continuous water flow to break thermal layer.

The unit runs on a standard dedicated outlet and arrives fully assembled.

Built on the exact same compact frame as the D1, this version upgrades your experience by introducing "RiverMode+™"— a dual-pump system that creates even stronger active current to break thermal barrier.
