The MiHigh Cold Plunge Tub is an inflatable, barrel-style tub that The Spruce named its best inflatable pick after setting it up on a patio. The Spruce found it inflated quickly with the included hand pump and that MiHigh's optional electric chiller hooked up easily and chilled the water fast. Its reservations: the chiller only goes down to 41 degrees, the tub is tough to climb into for shorter people, and the control panel has no lockout.

Strengths
  • — Inflated quickly and easily with the included hand pump in The Spruce's setup
  • — MiHigh's optional chiller hooked up easily and chilled the water fast, per The Spruce
  • — Clip-on cover kept debris out and stopped a toddler from pulling it off, The Spruce found
Watch-outs
  • — The chiller bottoms out at 41°F and does not get as cold as others, per The Spruce
  • — Tough to get into for shorter people, The Spruce notes
  • — No way to lock out the controls, so the temperature can be changed by accident

Plunge Original
1 sourceall derived$6,790as of Oct 10

The Plunge Original is built to be used every day without becoming a chore. Michael Kummer, who has run one for over two years, reports the chiller holding its set temperature down to 39°F indefinitely with no fiddling, and a 20-micron filter paired with ozone sanitation keeping the water clear for months between changes. The acrylic and fiberglass shell suits an indoor or outdoor installation. The limits are that it does not go as cold as some rivals, that the chiller has no scheduling or app control, and that at six feet tall Kummer has to choose between his toes and his knees in the standard length.

Strengths
  • — Cools water to as low as 39°F with Pro Chiller
  • — Features advanced filtration system with 20-micron filter and ozone sanitation
  • — Requires minimal maintenance and offers clean, clear water for several months
Watch-outs
  • — Doesn't get as cold as some competing cold plunge tubs
  • — Standard model may not accommodate people over 6 feet tall

How they stack up

MiHigh Cold Plunge Tub

Like the Sun Home Portable Cold Plunge, the MiHigh Cold Plunge Tub is an inflatable tub with a separate chiller. It holds 92 gallons to the Sun Home Portable's 128, and its optional chiller goes down to 41°F where Garage Gym Reviews lists the Sun Home Portable's at 37.5°F. The Plunge Original and Plunge All In are rigid acrylic and fiberglass tubs rather than inflatables.

Plunge Original

The Plunge Original cools to 39°F, which is not as cold as the 37.5°F Garage Gym Reviews lists for the Sun Home Portable Cold Plunge. Its chiller has no scheduling or app control, where the Plunge All In sets temperature and tracks sessions through an app. It pairs a 20-micron filter with ozone sanitation, shares an acrylic and fiberglass shell with the All In, and costs far less than the Sun Home Cold Plunge Pro.
