Cryospring Barton Cold Plunge

Cryospring builds the Barton around capacity and insulation rather than raw chilling power. The tub is rotomolded and hand-assembled in Minnesota, measures 86.75 by 33.5 by 35.5 inches externally with a 53.25 by 26 by 27.25-inch interior, and holds 150 gallons — which the brand says fits up to two adults and full immersion for anyone up to 7'4". Up to 4.5 inches of insulation and a tight-sealing, locking child-safety lid are claimed to cut chiller run time, while all equipment and plumbing sit concealed behind an integrated cover with a drip pan. The 1/2 HP chiller with "power boost" cools to 39 °F, circulates 1,200 gallons per hour, and draws a maximum of 620W (6.9A) from a standard 110V outlet. Water care pairs a 100 mg/hr ozone generator (scheduled via your own outlet timer) with oversized Cryopure 50-micron filters the brand rates for three times typical filter life.

What the page does not state matters too: there is no published noise figure, and Cryospring is a young direct-to-consumer brand without a public corporate history, so long-term support is less proven than legacy names. The 39 °F floor on 150 gallons means the Barton prioritizes steady, well-insulated cold over extreme minimums — buyers chasing sub-35 °F water should look elsewhere, while those wanting a rigid, family-safe two-person tub with unusually low visual clutter get a lot of hardware for $3,999. A 1-year home/commercial warranty is standard, with paid extensions to four years.
