The Sun Home Cold Plunge Pro gets to a real ice bath, with an advanced cooling system that builds thick floating ice down to 32°F.

The premium pricing and power requirements will put it out of reach for some.

How they stack up

Plunge All In

The Plunge All In adds app-controlled temperature setting and session tracking, which the Plunge Original's chiller lacks, and the two share an acrylic and fiberglass shell. It cools to 37°F and at 270 lbs without water it is lighter than the 345 lb Sun Home Cold Plunge Pro. It costs far less than the Pro and is for residential use only.

Sun Home Cold Plunge Pro

The Sun Home Cold Plunge Pro is described as reaching 32°F with floating ice, colder than the 39°F of the Plunge Original and the 37°F listed for the Plunge All In. It shares app control and a 1HP chiller with the Sun Home Portable Cold Plunge, but uses a 316-grade stainless steel tub holding 150 gallons where the Portable is a 128-gallon inflatable. It costs far more than the Plunge All In and the Plunge Original.
