Handcrafted Cold Plunge Design Meets Everyday Performance

The Kooru Cold Plunge Tub brings together handcrafted redwood construction, thoughtful engineering, and an integrated cooling and water-care system to create a cold plunge that feels more like a piece of premium furniture than traditional recovery equipment.

Handcrafted in San Diego from selected redwood, each Kooru tub is individually finished using Shou Sugi Ban, a traditional Japanese wood-charring technique used to enhance the wood's durability while bringing out the natural depth and character of its grain. Because each tub is handcrafted, subtle variations make every piece unique.

Behind the exterior is a complete cold-plunge system featuring a 1/4 HP chiller, 950 GPH circulation pump, ozone water sanitation, adjustable temperature control, and standard 110V operation. The approximately 60-gallon tub arrives set up for a streamlined ownership experience without requiring specialized high-voltage electrical service.

Why You'll Love It

Handcrafted Redwood Construction

Each Kooru is handcrafted in San Diego using carefully selected redwood, creating a premium cold plunge designed to complement luxury home gyms, wellness rooms, patios, and other thoughtfully designed spaces.

Traditional Shou Sugi Ban Finish

Kooru uses the Japanese technique of Shou Sugi Ban, in which the surface of the wood is carefully charred, sanded, and finished. The process highlights the exposed grain and creates the rich character that distinguishes the Kooru from conventional acrylic or inflatable cold plunges.

Integrated 1/4 HP Chiller

The included 1/4 HP chiller actively manages water temperature, removing the need to continually add bags of ice before each plunge.

950 GPH Circulation Pump

A 950 gallon-per-hour pump continuously circulates water through the system during operation.

Ozone Water Sanitation

The Kooru incorporates an ozonator (O₃) into its water-care system to support ongoing water sanitation without relying solely on frequent water replacement.

Adjustable Temperature Control

A programmable chiller allows you to adjust the water temperature to suit your preferred cold immersion routine.

Approximately 60-Gallon Capacity

The tub holds approximately 60 gallons of water, with water level adjustable based on user displacement and preferred immersion depth.

Standard 110V Power

Despite its integrated cooling and circulation system, the Kooru operates from a regular 110V household outlet, with typical power usage listed at approximately 350–500 watts and 3–5 amps. A properly grounded or GFCI-protected outlet should be used as required by applicable electrical codes.

Multiple Premium Finishes

The Kooru is currently offered in several exterior finish options, including Natural, Oiled Leather, Spanish Oak, Dark Natural, and Teak, allowing the tub to complement a range of wellness-space aesthetics.

Designed to Be Seen

Most cold plunges are designed primarily as equipment. The Kooru takes a different approach.

Its handcrafted redwood exterior, visible wood grain, and furniture-inspired design make it especially well suited for homeowners who care about how their wellness equipment looks within the space.

Whether positioned in a dedicated home wellness sanctuary, gym, or appropriately prepared setting, the Kooru can serve as a centerpiece rather than something you feel the need to hide away.

Pair it with a sauna to create a beautifully coordinated hot-and-cold wellness space built around your daily routine.

Shipping & Installation

Each Kooru is handcrafted, and the current supplier states that production takes approximately two weeks, with shipping time varying by location and commonly adding approximately another two weeks. I would not promise those exact lead times on your store unless they match your own supplier arrangement, so I would keep your customer-facing shipping copy more flexible.

The assembled tub weighs approximately 400 lbs, so customers should plan its final placement and access route before delivery. At least 33 inches of clearance is recommended through doors and passages.

The Kooru operates on standard 110V power and should be connected to a properly grounded/GFCI-protected outlet in accordance with applicable electrical requirements.
