Our vertical design is an intentional engineering choice to maximize both effectiveness and practicality.

1. Enhanced Therapeutic Effects: The upright position allows for full-body immersion up to the neck while making it easier to practice deep, diaphragmatic breathing. Research shows this posture promotes more efficient blood circulation and faster cold adaptation compared to lying down.

2. Space Efficiency: A vertical tub has a much smaller footprint than a horizontal one, making it ideal for any space—a home gym, a balcony, or the corner of a patio.

3. Ease of Access: Getting in and out of a vertical tub is safer and requires less effort, which is a significant advantage when your body is stiff from the cold.

Absolutely. The Still Plunge tub is designed to comfortably accommodate users up to 6'6" (198cm) tall. The internal dimensions are approximately 31.5 inches (80cm) in diameter and 24 inches (61cm) in height, providing ample room for full-body immersion and a comfortable experience.

The system is designed for a true "plug-and-plunge" experience. The entire process is tool-free and takes just 15-20 minutes.

1. Inflate the tub using the included high-speed pump (5-10 mins).
2. Connect the chiller's two hoses to the tub's inlet and outlet ports using the hand-tighten quick-connect fittings (1 min).
3. Fill the tub with a garden hose, plug the chiller into a standard outlet, and set your desired temperature on the intuitive touch panel or via the Wi-Fi app.

Our 1 HP Still Plunge Chiller is a performance powerhouse. In a standard 90-gallon tub at an ambient temperature of 77°F, it can cool the water down to a crisp 32°F in approximately 3-4 hours. This is up to 3x faster than many underpowered or inefficient units on the market that can take 12+ hours. The combination of a powerful compressor and the tub's thick insulation means less time waiting and more time plunging.

Yes, the system is designed for continuous 24/7 operation. It's highly energy-efficient, with running costs comparable to a modern refrigerator. After the initial cooling period, the chiller only cycles on intermittently to maintain the set temperature. Thanks to the tub's excellent insulation and our efficient 1 HP compressor, the estimated monthly cost is between $25 and $35 USD, depending on your local electricity rates and climate. This is significantly cheaper and more convenient than the daily cost of buying ice bags.

Yes, both the tub and chiller are engineered for robust indoor and outdoor use. The chiller features an IPX4 weather-resistant casing, protecting it from splashes and rain. It operates flawlessly in extreme heat and down to freezing temperatures. However, if ambient temperatures are expected to drop below 14°F for a prolonged period, we recommend draining the unit to prevent any risk of damage from ice expansion.

To get the best performance and efficiency from your system, follow these simple placement tips:

• Level Surface: Ensure both the tub and chiller are on a flat, stable surface.
• Proper Airflow: Leave at least 12 inches (30cm) of clear space around the chiller's vents for ventilation.
• Power Access: Place the unit within 5 feet (1.5m) of a standard, grounded power outlet.
• Shade is Key: If outdoors, placing the chiller in a shaded area (like under a patio or awning) will significantly improve cooling efficiency and reduce energy consumption.

Consistency is more important than duration. For optimal benefits, aim for a total of 11-15 minutes per week, spread across 2-4 sessions.

• Beginners: Start with 1-3 minutes per session at a warmer temperature like 50-55°F.
• Intermediate/Advanced: A session of 2-5 minutes at 37-45°F is highly effective.
• Recovery: Allow at least 24 hours between sessions for your body to adapt.

Controlling your breath is key to mastering the cold. Follow this guide for an optimal and safe experience:

1. Set Temperature: 32°F-39°F is optimal for advanced users; beginners should start at 45-55°F.
2. Enter Calmly: As your body first touches the water, perform a long, forceful exhale to override the gasp reflex.
3. Breathe Intentionally: Immediately begin a controlled breathing pattern like "Box Breathing": Inhale for 4 seconds, hold for 4, exhale for 4, and hold for 4.
4. Submerge to Shoulders: Keep your head above water.
5. Embrace the Shiver: Do not fight the natural shiver response. Continue your steady breathing.
6. Exit Safely: After your planned duration (2-5 minutes), exit calmly.
7. Rewarm Naturally: Pat yourself dry with a towel. Avoid a hot shower immediately; allow your body to rewarm on its own for maximum benefit.

Yes, you can use an intermittent protocol to maximize the activation of Brown Adipose Tissue (BAT), a type of fat that burns energy to create heat.

The Metabolic Boost Protocol:

• First Set: Enter the water and stay in until you begin to shiver consistently (typically 1-3 minutes).
• Rewarm Phase: Exit the tub but do not towel off. Allow your body to shiver in the air for 60-120 seconds.
• Subsequent Sets: When the shivering subsides, re-enter the water.
• Repeat: Perform 2-4 total sets based on your tolerance.

Our advanced Purity-Flow™ Dual-Stage System ensures your water stays pristine for weeks without harsh chemicals. It works in two powerful stages:

1. Particle Filtration: A replaceable 20-micron filter cartridge continuously circulates water, trapping physical debris like hair, skin cells, and dust before they can break down.

2. Ozone Sanitization: An integrated high-output Ozone generator automatically runs on a cycle, neutralizing 99.9% of invisible bacteria, viruses, and other microorganisms. This powerful, chemical-free combination guarantees crystal-clear and safe water at all times.

Ozone (O₃) is a natural, powerful oxidizing agent that is 50 times more effective at killing bacteria and viruses than chlorine. Our system generates ozone and injects it into the water, where it instantly neutralizes contaminants on contact.

Within about 20 minutes, the ozone naturally reverts back to pure oxygen (O₂), leaving zero chemical residue in the water.

The advantages over chlorine are immense:

• No Chemical Smell: Enjoy a completely odorless experience.
• No Skin Irritation: It's gentle on your skin and eyes.
• No Harmful Byproducts: Unlike chlorine, it doesn't create chloramines.
• Fully Automated: No need to buy, store, or handle harsh chemicals.

Our system is designed for minimal maintenance. The sealed heat pump system requires no professional servicing for 10+ years.

Your simple routine is:

• Replace Filter Cartridge: Every 1-2 months, depending on usage. Your bundle includes a 6-month supply.
• Change Water: Thanks to the advanced purification, you only need to change the water every 4-6 weeks.

Our Ironclad Promise is designed to give you complete peace of mind.

Your safety is our absolute priority. While cold plunging is highly beneficial, it must be approached with respect and awareness. Always follow these essential guidelines:

• Consult Your Doctor: Before beginning any cold plunge practice, consult with a healthcare professional, especially if you have pre-existing conditions such as cardiovascular issues, high blood pressure, diabetes, are pregnant, or have a history of seizures.
• Never Plunge Alone: Always have someone nearby who can assist you in case of an emergency, especially when you are new to the practice.
• Listen to Your Body: There's a difference between uncomfortable and unsafe. Learn to recognize your limits. If you start to feel dizzy, light-headed, severe numbness, or uncontrollable shaking, exit the water immediately.
• Keep Your Head Above Water: Unless you are a highly experienced practitioner following a specific protocol, always keep your head out of the water to prevent the dive reflex from affecting your heart rate and breathing.
• Start Slow: Do not rush the process. Begin with shorter durations (1-2 minutes) and warmer temperatures (50-55°F) and gradually increase the intensity as your body adapts.
• Avoid Alcohol: Never use a cold plunge after consuming alcohol, as it impairs your body's ability to regulate temperature and your judgment.
