Cold Therapy Chiller & Insulated Tub

Cold plunging (cold water immersion) offers a cascade of benefits for both body and mind. Research shows it can:
• Improve Circulation & Muscle Recovery: The rapid constriction and dilation of blood vessels helps flush out inflammation and reduces muscle soreness. This process supports faster recovery and better cardiovascular efficiency.
• Boost Metabolism & Activate Brown Fat: Regular exposure can trigger brown fat activation, increasing your metabolic rate and enhancing insulin sensitivity—supporting healthy weight management when combined with a balanced lifestyle.
• Enhance Immune Function: Cold exposure can stimulate white blood cell production, with studies noting up to 29% fewer sick days when cold showers were taken consistently.
• Elevate Mood & Mental Clarity: The release of endorphins and norepinephrine during a cold plunge can improve your mood, reduce stress, and sharpen focus.
Remember: Always start slowly and consult a healthcare provider if you have underlying condition

No—our cold plunge tubs come with powerful built-in chillers that maintain your set temperature, so there’s no need to add ice. Simply fill the tub, set your desired temperature, and let the chiller work its magic.
However, if you desire an extra frosty experience, you can add ice temporarily:
• Initial Cool-Down: A few ice cubes can help bring tap water down faster before the chiller takes over.
• Ultra-Low Temps: If you’re aiming for near-freezing water, a bit of ice can push the limits further.
• Backup Option: For models without a built-in chiller or during power outages, ice remains a viable option.

The ideal temperature depends on your experience and comfort:
• Beginners: Start at 50–59°F (10–15°C) for a gentle introduction.
• Intermediate Users: Once acclimated, try 41–50°F (5–10°C); many find around 45°F (7°C) to be the sweet spot.
• Advanced Users: Those well-adapted may venture into the high 30s°F (~4°C), but going below 39–40°F isn’t recommended for safety.
Pro Tip: Choose a temperature that gives you a sharp inhale but remains tolerable for 1–2 minutes. Start warmer and gradually dial it down as your body adapts.

Even brief sessions can be effective:
• Start Short: For beginners, 30–60 seconds is a great starting point to build tolerance.
• Typical Session: Most users find 2–3 minutes to be the ideal duration to trigger the benefits without overdoing it.
• Maximum Duration: Generally, sessions shouldn’t exceed 5 minutes continuously in very cold water to avoid potential risks like numbness or excessive core temperature drop.
Always listen to your body—if you experience prolonged shivering, dizziness, or discomfort, exit the tub and warm up.

No special plumbing is required. Our cold plunge tubs are self-contained with built-in pumping and filtration systems. Simply fill the tub with a standard garden hose and plug it into an electrical outlet. This plug-and-play design means you can set it up on a deck, patio, garage, or gym room without any remodeling or the need for a plumber.

Routine water maintenance is key:
•Standard Use:Change the water every 2–4 weeks if you use the tub frequently.
•With Filtration & Sanitation:If you utilize built-in filtration and sanitation methods (like ozone or UV purification), you might extend the water change cycle to every 2–3 months.
•Without Sanitizers:If you prefer pure water with no additives, you may need to change it more often (about every 2 weeks).
Watch for signs like cloudy water or odor. A simple drain and refill will ensure a fresh, inviting plunge every time. See our Maintenance Guide for more details.

Yes—you can use a cold plunge indoors. Here are some tips:
• Choose a Suitable Spot: Place the tub on a water-resistant surface (tile, concrete, etc.), ideally near a floor drain, and consider using a waterproof mat or tray.
• Ensure Proper Ventilation: Cold water can cause condensation; open a window or use a fan/dehumidifier to manage humidity.
• Check Floor Support: A filled tub is heavy (700–1000+ lbs), so ensure your floor can support it, especially on upper levels.
Indoor use offers privacy and protection from weather extremes, making it a convenient option for many.

Many of our premium cold plunge models include a built-in chiller unit that maintains your desired temperature (often down to 39°F).
If you prefer a model without an integrated chiller—or already have a tub—we also offer standalone chiller units that can be purchased separately. This gives you the flexibility to customize your cold therapy setup based on your needs and budget.
Chiller vs. Ice: Traditional ice baths are less consistent and more costly over time. An electric chiller provides steady, precise control for a reliable, on-demand cold plunge experience.
