Bring commercial-quality cold-water immersion into a beautifully handcrafted design with the Kooru Cold Plunge Tub, a premium refrigerated plunge system built from hand-selected redwood and designed for simple, everyday use.
Handcrafted in San Diego, California, the Kooru combines traditional woodworking with an integrated cooling and water-treatment system. Each tub is individually finished using Shou Sugi Ban, the traditional Japanese technique of carefully charring and finishing the wood surface to enhance its appearance and durability.
Unlike a basic plunge tub that requires bags of ice, the Kooru incorporates its own ¼ HP chiller, 950 GPH circulation pump, filtration, and ozone sanitation system, creating a complete cold-plunge installation in a single integrated design.
The approximately 60-gallon tub provides generous immersion depth while maintaining a relatively compact 64" L × 34" W × 35" H exterior footprint.
Best of all, the complete system operates from a standard 110V electrical connection, with typical power consumption of approximately 350–500 watts, making installation considerably simpler than many high-powered recovery systems.
Available in multiple handcrafted wood finishes, the Kooru is designed to look as much like a premium piece of outdoor furniture as it does a serious piece of recovery equipment.
Handcrafted in San Diego
Each Kooru Cold Plunge is handcrafted in San Diego from carefully selected redwood.
Rather than surrounding the plunge with molded plastic or a mass-produced synthetic cabinet, Kooru uses real wood to create a distinctive enclosure that can complement premium home gyms, patios, wellness spaces, and appropriately configured outdoor environments.
Because each tub is handcrafted from natural materials, subtle variations in wood grain, texture, and dimensions are a normal part of the product.
Traditional Shou Sugi Ban Wood Finishing
Kooru incorporates the traditional Japanese technique commonly known as Shou Sugi Ban into its woodworking process.
The surface of the selected redwood is carefully fired and sanded to accentuate the natural grain and create the distinctive depth and contrast visible across the available finishes.
The technique has historically been used as a method of preserving wood while creating a unique architectural finish.
Integrated Chiller — No Bags of Ice Required
The Kooru is supplied as a complete refrigerated cold-plunge system.
An integrated ¼ HP chiller actively cools the circulating water, eliminating the need to continually purchase and add bags of ice for normal temperature management.
Simply select the desired operating temperature using the system's controls and allow the integrated cooling system to manage the water.
950 GPH Water Circulation
A 950 gallon-per-hour circulation pump continuously moves water through the cooling and treatment system.
Consistent circulation helps distribute cooled water throughout the tub while moving water through the filtration and ozone-sanitation components.
Integrated Ozone Water Treatment
The Kooru incorporates an ozone sanitation system that introduces ozone (O3) into the circulating water.
Ozone is commonly used in water-treatment applications as an oxidizing agent and helps reduce reliance on more intensive manual water-treatment routines.
The ozone system works alongside filtration and circulation to help maintain the plunge water between routine maintenance intervals.
Approximately 60-Gallon Capacity
The Kooru holds approximately 60 gallons of water.
Actual fill level can be adjusted according to the user's size, displacement, and preferred immersion depth.
The tub's interior compartment measures approximately 36" L × 24" W × 30" H, providing enough depth for many users to achieve shoulder- or neck-level immersion depending on body size and water level.
Standard 110V Electrical Operation
Despite incorporating active refrigeration, circulation, and sanitation, the Kooru is designed to operate from a standard 110V electrical connection.
Typical operating consumption is approximately 350–500 watts at 3–5 amps, reducing the electrical-installation requirements compared with many larger heating and cooling systems.
An appropriately protected grounded/GFCI electrical connection should be used according to applicable installation requirements.
Integrated Equipment Compartment
The cooling, circulation, and water-treatment components are integrated into the Kooru's enclosure.
This creates a cleaner installation than systems requiring a separate external chiller positioned alongside the plunge.
It also allows the Kooru to arrive largely configured as a complete system rather than requiring the customer to design a separate tub, plumbing, pump, and cooling installation.
Designed for Straightforward Maintenance
The integrated filtration and sanitation systems are designed to simplify ongoing water maintenance.
Filter replacement is typically recommended approximately every one to two months, although actual replacement frequency depends on usage, water conditions, and maintenance practices.
