Kooru Cold Plunge Tub

Passionately handcrafted using sustainable and ethically sourced materials.

Each Kooru cold plunge is handcrafted from hand-selected redwood, arrives completely set up, and requires only a standard 110V outlet to operate. A beautiful, low-maintenance tub that removes every barrier between you and the mental and physical benefits of cold therapy.

Every board is carefully fired and sanded using the Japanese tradition of Shou Sugi Ban — an ancient technique that enhances durability, deepens color, and exposes the natural grain for a stunning finish suited to both modern and rustic settings. The result is an unmatched depth of character in the wood, and a tub built to last.
