Here’s a quick guide to setting up the Supertub. For more detailed instructions, you can refer to the Supertub setup and maintenance page, with video tutorials.

1. Unbox Everything You Need

Make sure you have all three kits: Supertub Kit, Permafrost™ Chiller Kit, and Water Balancing Kit. Start by unboxing the Supertub and its accessories.

2. Pick the Perfect Spot

Place your Supertub indoors or outdoors (in a sheltered area) on a flat, smooth surface. Make sure you have access to a power outlet and water source.

3. Quick Assembly

• Install water valves: Hand-screw the valves onto the marked connectors (A & B).
• Inflate the tub: Use the included air pump—just set to 10 PSI and let it run.
• Attach hoses and chiller: Connect hoses from chiller to Supertub (A to A, B to B). Ensure rubber washers are in place to prevent leaks.

4. Fill With Water

Fill to the marked level—don’t overfill.

5. Power Up & Set Temperature

• Plug in the chiller and test the circuit breaker using the “T Test” button.
• Power on, open water valves, and set your desired temperature (start at 50°F/10°C if you’re new). Allow several hours for water to reach target temp.

6. After Use

Always cover your Supertub when not in use. The chiller can stay on 24/7 for clean, cold water. If you turn it off, run for 30 minutes every 8 hours to keep water fresh.

Cold plunging offers a wide range of health benefits—from improved mood and resilience to faster muscle recovery and better metabolism. To get the most out of your practice, tailor your protocol to your specific goals:

The Søberg Principle

Dr. Susanna Søberg’s research found that just 11 minutes of cold water exposure per week—spread over 2 to 4 sessions at temperatures below 15°C (59°F)—can deliver significant metabolic, cardiovascular, and immune system benefits. Most users aim for 2–5 minutes per session, which is enough to trigger these positive effects without overexposure.

When to Cold Plunge?

Cold plunging triggers a powerful release of dopamine and adrenaline, making it an ideal tool for boosting alertness and energy—perfect for mornings or as a midday reset.

TIP: Avoid cold plunging within 2–3 hours of bedtime, as it can make it harder to wind down.

If muscle recovery is your priority, cold plunging immediately after intense exercise can help reduce inflammation and soreness.

However, if your main goal is muscle growth, wait several hours after your workout before plunging, as immediate cold exposure can temporarily blunt the muscle-building response.

Contrast Therapy:

Alternate between cold plunges (1–3 minutes) and heat (10–15 minutes in a sauna or hot shower), repeating the cycle 2–3 times.

Benefits:

Contrast therapy is popular for accelerating recovery, reducing swelling, boosting circulation, and providing a powerful mood lift.

BREATHING TIP:

The Wim Hof Method

Many cold plunge enthusiasts use Wim Hof’s controlled breathing technique to manage the initial shock and calm their nerves. Take a few deep, steady breaths before entering the water. Once inside, focus on slow, deliberate exhalations (in through the nose, out through the mouth). This helps keep your body relaxed and your mind centered, making the plunge feel more manageable—especially in those challenging first 60 seconds.

What to Expect on Your First Plunge

Before: You may feel nervous or even intimidated before your first plunge. That’s totally normal—anticipation is often the hardest part.

During: As you enter the water, expect an intense shock—your skin will tingle, and your breathing may speed up. Focus on slow, deep breaths to help your body adapt. After the first 30–60 seconds, the discomfort usually fades and you’ll start to feel more in control.

After: You’ll likely feel a rush of energy, increased alertness, and even a mild euphoria as your body warms up. Many people report a powerful sense of accomplishment and well-being.
