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

Sun Home Portable Cold Plunge
Ranked #4 in Best Cold Plunge Tubs
Sun Home Portable Cold Plunge
1 source$3,999as of Oct 10

The Sun Home Portable Cold Plunge pairs an inflatable, puncture-resistant tub with a standalone chiller that Garage Gym Reviews lists at 37.5°F to 104°F, so it doubles as a warm soak. Forbes named Sun Home the best cold plunge tub overall, calling the Portable 'A Durable, Inflatable Tub That Maintains Itself,' and found its 1HP chiller took water from hose temperature to sub-50 degrees in three hours. App control over Wi-Fi, ozone sanitation and a 20-micron filter keep upkeep light. It needs a dedicated 15-amp GFCI circuit, and the chiller only runs when ambient temperatures are above 40°F.

Strengths
  • — Inflatable tub sets up in about 20 minutes with no tools and deflates for storage, per Sarah Beth Yoga
  • — Ozone injection plus mesh and 20-micron filters keep the water fresh for weeks between changes
  • — Smartphone-connected control via Sun Home mobile app allows remote operation
Watch-outs
  • — Garage Gym Reviews rated cleaning and draining 3.5 out of 5; its tester notes the drain ports sit a few inches from the bottom of the tub
  • — Garage Gym Reviews lists it as expensive, sized for one person, and notes the external chiller weighs 88 pounds

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.

Sun Home Portable Cold Plunge

The Sun Home Portable Cold Plunge costs far less than the Sun Home Cold Plunge Pro and keeps a 1HP chiller and app control, but swaps the Pro's 316-grade stainless steel tub for an inflatable one holding 128 gallons to the Pro's 150. Garage Gym Reviews lists its chiller down to 37.5°F, colder than the 39°F of the Plunge Original, whose chiller has no app control. The MiHigh Cold Plunge Tub is also inflatable but smaller at 92 gallons.
