About This Collection
Three ways into cold water.
Cold plunge chillers solve the ice problem: they cool (and on the Basic model, also heat) your plunge water to a set temperature and hold it there, with WiFi control from your phone. No ice runs, no guesswork — just a plunge that's ready at your target temperature every morning. Both chillers pair with the rigid tubs in our cold plunge collection and ship free from an authorized Dynamic Cold Therapy dealer.

Common Questions
Cold plunges, answered plainly.
How cold do these plunge tubs get?
Most models cool the water to 37–60°F and hold it there with a built-in chiller, so your plunge is ready whenever you are. Filtration plus ozone or UV sanitation keeps the water clean between sessions.
How do I install and fill a cold plunge?
Most plug into a standard 120V household outlet and fill with a garden hose — no plumbing required. Set it on a level surface indoors or outdoors, plug in the chiller, and it's ready in a few hours.
How often should I cold plunge?
Many users plunge 3–5 times a week for 2–5 minutes. Start short and not-too-cold, then build up over time. Always listen to your body, and check with your doctor first if you have heart or blood-pressure concerns.
Inflatable, barrel, or chiller-equipped — which should I buy first?
If you're new to cold exposure, start with a $499 inflatable and prove the habit before spending more. If you already plunge regularly, skip to a chiller-equipped model — hauling bags of ice gets old fast, and a chiller holds your exact temperature around the clock.
Do I need a chiller, or can I just use cold tap water and ice?
Tap water and ice work fine in the barrel and inflatable tubs — that's how most people start. A chiller earns its price in summer, when tap water runs warm and holding 39–50°F by ice alone takes several bags per session. Chiller models also filter continuously, so the water stays clean between plunges.
