Michael Phelps’ Cold Water Journey
Michael Phelps wasn’t always a believer in cold water immersion. When his trainer first told him to step into an icy tub, his answer was simple: “No.” He got in—lasted all of 10 to 15 seconds—and swore he’d never do it again.
Then came the next day.
Five minutes in the tub. And a lifelong routine was born.
Since that moment, cold therapy has been a core part of Michael Phelps’ recovery routine. Whether it was during his record-breaking career or in retirement, he’s stuck to what works. “If something is working, I don’t change it,” Phelps says. “This helps my body feel good every single day.”
But after retiring from competitive swimming, home recovery came with its own challenges. He was often taking ice baths at home, not a training center. He found himself making weekly trips to the store, buying bag after bag of ice,
filling up coolers, and watching the effort melt away after just a few uses. The market offered few cold tubs that could meet his needs—none that could comfortably accommodate his 6’4” frame or match the performance he was used to.
A Shared Vision for Better Recovery
Phelps had already been working with Master Spas since 2010. After Beijing, where he cemented his place in history with eight gold medals, he began collaborating with the brand to create swim spas that brought performance training home.
So when he imagined a cold tub that actually delivered, he brought that vision to Master Spas—confident they could turn the idea into reality.
They did.
Built with Michael Phelps’ insights and the unmatched engineering of Master Spas, the Michael Phelps Chilly GOAT Cold Tub was born. Designed for elite-level recovery, built for everyday use, and shaped by the experience of a world-class athlete who knows what greatness requires.
As Phelps puts it:
