Cold Plunges FAQs

Regular cold-water exposure can boost mood and energy levels, enhance mental acuity and focus, build resilience, aid in muscle recovery and soothe sore muscles, and promote overall wellness.

When shopping for a cold plunge, factors to consider include quality, durability, temperature range, energy efficiency and insulation, water care, filtration, and comfort.

Electric cold plunges have the unique advantage of being temperature controlled through a control panel or other connected device. Without constant temperature control, ice baths can make it hard to maintain a certain temperature without having to repeatedly add ice or wait for the ice to melt.

The temperature range is 40°F–80°F or 4°C–27°C.

Yes, it’s designed with energy efficiency in mind. The unit is fully insulated using a multi-density, closed-cell polyurethane foam, and comes with a custom-fitted cover featuring a 1 lb. core for added thermal protection. Together, these features help maintain consistent temperatures and minimize energy costs.

Our cold plunge is energy efficient, using roughly the same amount of electricity as a large household refrigerator or chest freezer. Under typical conditions—around 70°F ambient temperature with 50% humidity—it runs quietly and maintains low energy consumption. In more extreme temperatures, especially prolonged heat, the unit may run more frequently to maintain the desired water temperature, but overall electricity use remains relatively low for most environments.

The cold plunge can be installed indoors or outdoors, as long as the area is properly ventilated, with at least 24 in (61 cm) of clearance around the back and sides. The unit should sit on a reinforced concrete pad that is at least 4 in (10 cm) thick. Be sure to place it at least 5 ft (1.5 m) from any metal surfaces. Avoid shimming the unit to prevent cabinet warping and potential warranty issues. Refer to your Pre-Delivery Instructions for further guidance. Cold plunge is certified for indoor use only in Canada.

The cold plunge requires a dedicated 115-volt, 15-amp outlet. The 17 ft long GFCI cord must plug directly into the outlet; extension cords should not be used.

Yes. IMPORTANT: Because of shipping orientation, wait 24 hours to fill and start your cold plunge once it is installed. This allows internal components and refrigerants to settle properly

Avoid using bath salts and essential oils in the water, as they can clog or damage filters and pumps, disrupt water chemistry, and potentially void your warranty.

Cooling time depends on factors like ambient temperature and humidity. For example, in an environment where the ambient temperature is around 98°F, it takes approximately 10.5 hours to lower the water temperature from 80°F to 40°F. Cooler ambient conditions will generally allow the unit to reach the target temperature faster.

Cold plunge duration is highly individual and depends on your health, tolerance, and goals. Beginners should start with 1–2 minutes and may work up to 3–5 minutes for recovery and resilience. Before starting any cold plunge routine, consult your doctor to ensure it is safe for you, especially if you have underlying health conditions, circulatory issues, or sensitivities to cold exposure.

To maintain clean and fresh water, owners should drain and refill their cold plunge every 3–6 months.
