Frequently asked questions
What makes the The Barrel a standout choice?
The Barrel collection delivers a full cold immersion experience in a vertical, space-efficient form. Both the Cyber Barrel and the Star Treatment 2.0 are constructed from 316 marine-grade stainless steel, fully insulated, and paired with a 1.0 HP chiller capable of reaching 32°F. The Cyber Barrel is finished entirely in stainless steel for a minimalist, industrial profile. The Star Treatment 2.0 pairs a stainless steel interior with hand-finished wood paneling on the exterior. Each system includes steps, an insulated cover, and integrated filtration with ozone sanitation.
Who is The Barrel best suited for?
The Barrel is designed for anyone who values a compact footprint without compromising immersion depth. It suits patios, balconies, home gyms, and smaller outdoor spaces where a full-size rectangular system would not fit. Users who prefer an upright posture during cold immersion, or who find the aesthetic of a barrel-style system more aligned with their space, will find it particularly well suited. The Star Treatment 2.0 is the natural choice for those drawn to the look of wood. The Cyber Barrel is built for those who prefer a clean, all-metal finish.
Are the steps included with The Barrel?
Yes. A set of custom-fit steps is included with every Barrel purchase. They are engineered for safe, stable entry and exit at full barrel height. The barrel collection (excluding the black cyber barrel) also counts with an inner step that also works as a seat.
How much floor space does The Barrel need?
The Cyber Barrel requires a diameter of 34 inches. The Star Treatment 2.0 requires a diameter of 33.2 inches. Both fit comfortably in spaces where a traditional rectangular system would not. Allow at least 12 inches of clearance on all sides of the chiller for proper ventilation.
Does The Barrel chiller save money versus using bagged ice?
The savings are significant. A single session using bagged ice can cost $30 to $70, depending on volume. Over a year, that adds up to $4,000 to $9,000 or more. The included 1.0 HP ChillX chiller cools to 37°F on its own, with ice-making capability built in. It eliminates the recurring cost of bagged ice entirely.
Does The Barrel also function as a hot tub?
Yes. The chiller included with every Barrel system also heats water up to 107°F, making it a year-round tool for both cold immersion and warm water recovery or contrast therapy.
What are the electrical requirements for The Barrel?
The system plugs into a standard 120V dedicated outlet (15 Amps). No special wiring is required. A GFCI (ground-fault circuit interrupter) is included and should be used for electrical safety. Use a dedicated circuit breaker for the product.
Do I need special plumbing or a water line?
No. All Polar Monkey systems are fully self-contained. Fill it with a standard garden hose and the built-in filtration and sanitation systems handle the rest. No plumbing connection is needed.
