Kooru Cold Plunge Tub

The Kooru Redwood Cold Plunge Tub is a handcrafted cold plunge system made in San Diego from selected redwood. Each tub is finished using the traditional Japanese Shou Sugi Ban technique, which involves charring and sanding the wood surface to create a distinctive finish and highlight the natural grain.

The tub arrives fully set up and operates from a standard 110V electrical connection. It features an integrated 1/4 HP chiller and 950 GPH pump, along with an ozone water-treatment system and replaceable filtration.
