Am I buying the official Cold Plunge?
Why should I buy the official Cold Plunge?
The official Cold Plunge is rated the best overall cold-plunge tub by thespruce.com, a trusted home-improvement website with more than 32 million users per month. The website lauds the Cold Plunge Standard for itsÂ
- “attractive, self-contained design;Â
- “powerful cooling, sanitation, and filtration; and Â
- “water [that] lasts up to six months.” Â
A review on mindbodygreen.com touts the Plunge’s sleek design, its sturdy, insulated-acrylic composition, and its easy setup.Â
Can I put the Plunge outside?
How long or difficult is setup?
Setup is truly plug-and-play. All you’ll need is a sturdy surface on which to place the Plunge and (depending on the model) a dedicated, standard 15- or 20-amp GFCI 110 outlet nearby. Most of the setup time consists of waiting for the tub to fill with water.
Is the Plunge loud?
I'm a large person. Will I fit?
We recommend considering the XL if you stand 6 feet or taller so that you’ll have ample room for easy submersion. You want to be able to dunk your head right away to activate the body’s natural-heating mechanism. Â

My Plunge has no power
​If your Plunge is plugged into an extension cord it make sure it’s the 12-gauge, heavy duty outdoor kind. Anything rated lower than that can lead to power issues.
​​​​​​​​
- Check the breaker switch on the power strip inside the electrical box.Â
- Check the GFCI outlet the Plunge is plugged into to make sure it has not tripped.
- Check the house breaker to make sure that has not been tripped.
- Plug the Plunge power cord into a different outlet.
- Test each component individually by plugging them into an outlet on their own.
Why is my water not cooling?
- Use only a 12-gauge, heavy duty, outdoor extension cord if you use one at all.
- Leave at least 10 inches of space between the right side of the chiller and the closest wall or surface. Without adequate space, the chiller will not have proper air flow to work appropriately, and this will void the chiller warranty.
- Clean the chiller vents every no less often than every 90 days.
- Unplug your chiller from the power strip in the electrical box and plug it into a separate outlet. This can be the same outlet into which the Plunge is plugged.Â
- Check the air coming out of the back of the chiller.
- If the air is warm or hot, all is good.
- If the air is cool air, contact customer service.
- Perform an Air Purge in case air is trapped in the chiller, causing it not to properly cool the water. (Click here to watch our Air Purge video.)Â
- Let the Plunge run for 2 hours to see if water starts to cool.Â
- Plug the chiller into a separate outlet if the water isn’t cooling. This can be the same outlet the Plunge is plugged into.
- Test for another 2 hours.Â
My Plunge has sprung a leak!
My Plunge has little or no flow
- Check your pump settings.
- Make sure that you have a clean filter. A dirty filter will decrease water flow.
- Perform anAir Purge. Air can sometimes get trapped in the system, causing decreased flow.
- Commercial customers only; Clean out your commercial hair catch
- Clean out your pump.
- If your Plunge has had little flow, the chiller reservoir could be partially frozen, restricting your water flow.
- Do a deep clean. Sediment built up in the hoses can impede flow. We suggest a deep clean every 3 to 4 months. (Reference the deep-clean video as needed.
Â
- Check to see if your pump is getting power.
- Check the power connections.
- Â
- If that does not work, then unplug the pump from the power strip and plug it into a separate outlet. It can be the same outlet the Plunge is plugged into.Â
- Check the power connections.
- Commercial customers only: Clean out the commercial hair catch. (Do step 3 at the same time, while your Plunge is drained)Â
- Clean your pump. There could be an issue with the impeller.
- If your Plunge has had little or no flow the chiller reservoir could be frozen.
- Do a deep clean of the system. Sediment built up in the hoses could block in the system. We suggest a deep clean every 3 to 4 months. (Reference the deep–clean video as needed.)Â
My power keeps tripping off.
Why is my heater not working?
- Pro tip: Low water level creates less pressure in the system. Making sure your Plunge is “full” can help increase pressure.Â
- Indoors, full is a waterline 4.5 inches from top.Â
- Outdoors, full is a waterline 3 inches from top.Â
- If your heater works plugged into a separate outlet, contact customer service and let someone there know.Â
