IcyBull is a high-performance, stock-tank-based cold plunge system designed for those who want the durability of a Rubbermaid® commercial tank paired with professional-grade cooling technology. Available as a fully assembled Plug & Play system or a comprehensive DIY Kit, it offers the most versatile ice bath experience on the market.

Two Ways to Plunge

The Plug & Play: Fully assembled and tested. We do the heavy lifting; you just add water and find your grit.
The Kit: All the same premium components; the 1/3 HP chiller, pump, and insulation; for the hands-on athlete who wants to build their own elite setup.
Chiller is optional: This set-up is compatible with most 1/3HP chillers which means you don't have to go with ours

🌊 Revolutionizing Flow: The "River Mode" Advantage

Most cold plunges allow a "thermal layer" of warm water to form around your body, insulating you from the cold. The IcyBull™ features a proprietary variable-speed pump with an integrated speedometer, allowing you to choose your intensity:

Boost Cool Mode: A whisper-quiet, low-flow setting perfect for maximum filtration and maintaining temperature while you sleep.
River Mode: Our most powerful setting. It creates a continuous, high-velocity "river flow" that breaks the thermal barrier, ensuring your skin is constantly hit with fresh, chilled water for the most effective metabolic spike possible.

🛡️ Superior Neoprene Insulation Sleeve

Stop wasting energy. Our custom-engineered IcyBull™ wraps your stock-tank in nearly one inch of high-density neoprene and thermal underlayment.

Elastic Pressure Fit: The sleeve hugs the tank's curves to eliminate air gaps.
Condensation Management Performance: Drastically reduces condensation and keeps your water at 5°C (40°F) even in hot & humid environments.
Aesthetic & Durable: A rugged, printed exterior that turns a utility tank into a centerpiece.

What is the benefit of a "River Mode" in a cold plunge?

"River Mode" prevents the formation of a thermal boundary layer. When you sit still in cold water, your body heat warms the water immediately touching your skin. IcyBull's powerful flow breaks this layer, forcing your body to work harder to maintain its core temperature, which may increase the metabolic and anti-inflammatory benefits of the plunge.

Is a 1/3 HP chiller powerful enough for a stock tank?

Yes. Because the IcyBull™ uses a nearly 1-inch thick neoprene insulation sleeve, the 1/3 HP chiller operates with extreme efficiency. This combination provides faster "pull-down" times and maintains sub-50°F temperatures more consistently than uninsulated systems with larger, louder motors.

How difficult is it to maintain the water?

Maintenance is minimal. The system features an easy-swap filtration unit with ozone generator and a powerful pump that ensures 100% of the water is cycled and cleaned frequently. The included submersible LED and floor mat ensure the environment stays as clean as it is functional.
