Revolutionizing cold water therapy for those who strive to be bold

Designed with every detail in mind, the Michael Phelps Chilly GOAT Cold Tub by Master Spas provides exceptional contrast water therapy, comfort, and convenience. The Chilly GOAT features moving water to prevent a thermal barrier, LED lights for ambiance, and more. It’s time to say goodbye to those runs for bag after bag of ice, and enjoy clean, ice cold water when you need it.

Cold to hot

It’s official: Carrying bags of ice is no longer your cooldown. With the Chilly GOAT’s seriously powerful chiller, you can cool the water to a chilly 40 degrees. The components, including the chiller, are self-contained.

The Valaris contrast therapy tub allows you to seamlessly move from the revitalizing coolness of cold water therapy to the comforting warmth of hot water therapy. With 16 strategically placed massage jets, your body will experience an invigorating and therapeutic massage. The gentle, yet powerful streams of water target your tension points, relieving stress and muscle aches, leaving you feeling relaxed and rejuvenated.

The hot tub side of the Valaris also features room for two. Choose your favorite seat or share your soak with with someone else — whether it’s your training partner, friend, or family member.


Got WiFi? The Chilly GOAT does. Set the temperature of your cold tub conveniently from your smartphone.

In the cold seat

How do you want to plunge? With built-in seat and armrests, the Chilly GOAT becomes a comfortable space to get uncomfortable. The design also features a top deck for submerging your lower body, resting your arms, or resting your phone. Streaming the coolest playlist is 11/10 recommended. And when it comes to the details, the SoftTread™ Nonslip Comfort Flooring adds comfort and safety to your cold tub.

Easy water care

Contrast water therapy begins with clean, clear water. A built-in filtration system, including UV, keeps the water clear and clean with minimal chemicals. Every Chilly GOAT Cold Tub comes with a year’s supply* of chemicals, too.

* The amount of chemicals required can vary depending on how many people use the tub and how frequently people are in the water.

Cool, calm, and protected

The Chilly GOAT is not just a tub. It’s something more. With a thoughtful, striking design, the Chilly GOAT Cold Tub will complement any space, indoors or out. The all-weather, durable cabinet is easy to clean, and the full foam insulation helps maintain that chill. An internal drain simplifies maintenance, making it easy to drain and refill your cold tub every three to four months.

Cold pursuit

Don't take our word for it


I have seen a lot of physical benefits from spending time in cold water. But I have also seen the mental benefits of being in the Chilly GOAT Cold Tub. It’s a part of my daily routine.
