Sun Home Cold Plunge Horizontal review

The Sun Home Cold Plunge Horizontal is the cheapest way on this list to get a chiller that reaches 32°F. Sun Home sells it for $3,899 on sale against a regular price of $4,099, with free US shipping and a free infrared sauna blanket during its Black Friday promotion. The tub is inflatable, 77.2 in long and holds 128 gal of water, so it weighs only 15.5 lbs before filling; the chiller adds 88 lbs. Sanitation is by ozone injection, and the system plugs into a standard NEMA 5-15 outlet on a dedicated 15 amp GFCI circuit. Sun Home's setup guide asks owners to let the chiller stand upright for 4 hours before first use and to confirm water is flowing from the jets after filling. The compromises are the soft-sided tub, a warranty listed only as 1+ Year and no UV stage. For buyers who want near-freezing water without spending $5,000, it is the value pick.
