RevX Wellness is a founder-led California brand focused on one thing: cold plunge systems for the home that hold their temperature and stay clean. It was built by a cold plunge user, Mike Nigai, around a simple idea, that the chiller, the tub, and the filtration should be three separate parts that each do their job well.

The flagship X Tub reflects that. It is an acrylic shell 34 inches deep with three inches of foam insulation, paired with a 1.5 horsepower chiller on a Panasonic compressor and a titanium heat exchanger that holds water anywhere from 34 to 104 degrees Fahrenheit. A separate filtration loop runs the water through a 20-micron filter with UV and ozone, no chemicals, cycling the full tub about four times an hour.

Ellara carries RevX for that engineering, and stands behind it with the hands-on delivery and support a unit this size deserves.
