How To Add Ice to your Barrel Cold Plunge Tub

The amount of ice you add to a traditional barrel cold plunge tub depends on your desired water temperature and the starting temperature of the water. A general guideline is:

1. Typical Amount: Use about 40-60 lbs. (18-27 kilograms) of ice for a standard 150-gallon (570-liter) barrel tub if the water starts around room temperature (70°F/21°C) and you aim to lower it to around 50°F (10°C).
2. Colder Target Temperatures: To reach temperatures closer to 40°F (4°C), you may need 80-100 lbs. (36-45 kilograms) of ice.
3. Adjusting for Warmer Water: If the water is warmer or if you're in a hot climate, you might need more ice.

Tips:
• Add ice gradually and stir the water to distribute the cold evenly.
• Start with less ice and add more as needed to achieve your desired temperature.
• A thermometer can help you monitor the water temperature precisely.

Always ease into cold plunges to allow your body to adjust to the cold safely.
