Passionately Handcrafted Using Sustainable And Ethically Sourced Materials

Handcrafted in San Diego from selected redwood, the Kooru Cold Plunge arrives completely set up — the system is simple to maintain and runs on a standard 110V outlet. A beautiful, ready-to-use centerpiece for a consistent cold plunge practice.

Each tub is built with premier craftsmanship for the discerning buyer. We go that little bit extra in every step: from hand-selecting every board to carefully firing and sanding each one in the Japanese tradition of Shou Sugi Ban — the venerable method used to protect wood for centuries. The result is an unmatched depth of color and exposed grain — charred, protected wood against bright, clean water.

Description:

• Size approximately 64” L x 34” W x 35” H — at least 33 inches of clearance through doors/passages is needed for delivery placement. Due to the hand-crafted nature, dimensions may vary up to ¼”.
• Weight around 400 lbs (can be moved by two people via the corner posts, or with moving trolleys)
• Holds approximately 60 gallons; water height is adjustable based on body displacement — shoulder to neck/chin height for most users
• Chiller is 1/4 HP; pump is 950 GPH
• Water sanitation via Ozonator (O3)
• Typical power usage 350-500 watts at 3-5 amps on a regular 110-volt plug; outlets should be GFCI/grounded as required by state law
• Tub compartment 36” L x 24” W x 30” H, made of high-density polyurethane
• Filter replacement roughly every 1-2 months depending on usage
• Each tub is made to order; production time is about 2 weeks

Features:

Shou Sugi Ban burning:

• An ancient Japanese technique that preserves wood by charring the surface with a hot flame — enhancing durability and beautifying the grain for a stunning finish in modern and rustic settings alike.

Adjustable temperature control:

• Simple to use and maintain, with a programmable chiller and water treatment.

Natural water purification:

• Ozone is a potent oxidant that breaks down contaminants in water, eliminating the need for added chemicals without leaving harmful byproducts — an effective and environmentally friendly treatment method.
