Setting Up Your Cold Plunge Tub

Installing a cold plunge tub at home can be simple or sophisticated, depending on the type of tub you choose. Here’s a practical breakdown to help you get started the right way:

1. Choose the Right Location

• Indoors: Great for consistent temperatures and privacy. Ensure proper drainage and ventilation.
• Outdoors: Offers natural ambiance but requires weather-resistant materials and stable flooring.
• Tip: Place your tub near a power source if it includes an electric chiller.

2. Fill With Clean or Filtered Water

• Use filtered water for a longer tub lifespan and skin safety.
• If using tap water, clean or replace water regularly to prevent buildup.
• Some high-end models feature built-in filtration systems, which are ideal for daily use.

3. Cooling Methods

• Manual Ice Baths: Add bags of ice for instant cold (budget-friendly, more effort).
• Built-in Chillers: Many premium tubs like The Plunge All-In come with electric chillers that cool and filter water automatically, great for consistent cold therapy without daily ice runs.

4. Keep It Clean

• Use bromine tablets, Hydrogen peroxide, or UV purification, depending on the type of tub.
• Clean surfaces weekly and replace water every 2–4 weeks unless it is filtered.
• Some units have self-cleaning or ozone sanitation built-in.

5. Set and Monitor Temperature

• Ideal cold plunge range: 37°F to 55°F (3°C to 13°C).
• Use an external thermometer for DIY setups or digital controls for electric chillers.
• Start with shorter sessions (1–3 minutes) and gradually increase the duration as your body adapts.

Shop for accessories like water filters, thermometers, and lids to complete your setup.
