How they stack up

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.

Sun Home Portable Cold Plunge

This Sun Home model mirrors the cooling power of the Sun Home Cold Plunge Pro, reaching 32°F with floating ice, but is significantly heavier and less portable than the inflatable Hydragun Supertub. It offers more integrated performance than the shell-only Plunge Evolve, though its weight and power requirements make it less flexible than the compact Cold Pod XL.
