Cold plunges have so many great health benefits, but they can cost anywhere from $5,000 to $10,000. That’s why I created these easy-to-follow plans to build a beautiful cold plunge that efficiently chills to 39–41°F, while also including a sophisticated yet DIY-friendly filtration system that anyone can put together at home. I’ll walk you step by step through the entire process, using simple tools you likely already have, and I’ll also provide links to where you can source any additional parts needed for the build.
