Sun Home Portable Cold Plunge
Higher ratedRanked #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

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 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.
