About us

Born in California. Changing lives 


Plunge was born out of a garage in 2020 when the world shut down. There were a lot of things Michael Garrett — and the rest of us — didn't know. But what he did know was COVID-19 shut down his brick-and-mortar float spa business, and he was determined to build the world’s best cold plunge. Enlisting the help of his dad, he got to work. After countless iterations and improvements, he knew they had created something truly special. 

Shark Tank Spotlight

Our appearance on Shark Tank marked a pivotal moment for Plunge. The show catapulted our vision into the national spotlight, helping us connect with thousands who are now part of our growing community. If you discovered us through Shark Tank, we warmly welcome you to the Plunge family! Make sure to check out our Shark Tank page.

A new partnership

A friendship turned into a powerful partnership when Ryan Duey came on board. Michael and Ryan share a passion for wellness, giving back, and changing lives through cold plunging. Three years, an appearance on Shark Tank, and a 150,000 sq ft. warehouse later, they’re still following that passion, crafting innovative cold plunges and high-heat saunas in Sacramento, California.  


When the people obsessed with cold plunging and saunas are the ones making the plunges and saunas—something special happens. From the engineers behind our designs to the people building them in our warehouse, our passion leaves its fingerprints all over our products and drives us forward to keep innovating. 

Giving Back
