Plunge All In

The Plunge All-In Gen 2 is described as the world's smartest cold plunge, featuring a plug-and-plunge setup with no plumbing required. Experts noted it cools 31% faster using 50% less energy, and includes ozone sanitation with double filtration. The device is app-controlled for temperature setting and session tracking.

This makes it best suited for home users seeking a high-end, smart cold plunge experience, rather than commercial or budget-conscious buyers.

How they stack up

Plunge All In

The Plunge All In stands out as the most energy-efficient and fastest-cooling unit compared to the Sun Home Cold Plunge Pro, while offering a plug-and-play setup that avoids the plumbing complexity of the Plunge Evolve Air Pro Chiller + Heater. Although it is residential-only and pricey, it provides a smarter, more integrated experience than the basic Cold Pod XL.

Sun Home Cold Plunge Pro

The Sun Home Cold Plunge Pro distinguishes itself by reaching a true 32°F with floating ice, a feat unmatched by the Plunge Original or Plunge All In which top out at higher temperatures. While it shares app connectivity with the Plunge All In, it offers a more authentic ice-bath feel than the inflatable Hydragun Supertub, though it demands a dedicated 120V power supply unlike the portable Cold Pod XL.
