Sun Home Portable Cold Plunge

$3,999as of Jun 7

The Sun Home Cold Plunge™ Pro delivers an authentic ice bath experience with its next-generation cooling system that reaches 32°F, creating thick floating ice. Forbes Magazine called it a 'Formidable And Durable Powerhouse That's Fit For Olympians.' Business Insider noted it's 'the best cold plunge we've tested.'

How they stack up

Plunge Original

The Plunge Original balances performance and maintenance better than the complex Plunge Evolve Air Pro Chiller + Heater, offering reliable cooling to 39°F with advanced filtration. While it doesn't reach the freezing 32°F of the Sun Home Cold Plunge Pro, its sleek design and ease of use make it a superior daily driver compared to the no-frills 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.
