Sun Home Cold Plunge Pro
Ranked #2 in Best Cold Plunge Tubs
Sun Home Cold Plunge Pro
3 sources$13,999as of Oct 10

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. Caine Wilkes, an Olympian and weightlifting coach, reviewed it and praised the whisper-quiet operation and smartphone connectivity. The premium pricing and power requirements will put it out of reach for some. Serious athletes who want high-performance cold therapy are the fit; casual users may find alternatives more cost-effective.

Strengths
  • — Next-gen ice generator creates thick floating ice that reaches 32°F for authentic ice bath experience
  • — Intuitive drainage system allows easy emptying with or without hose
  • — Smartphone-connected control via Sun Home mobile app enables remote operation
Watch-outs
  • — High price point with premium features
  • — Requires 120V, 12A power supply which may limit placement options

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

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.

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.
