Description

The Plunge (sold as The Plunge: Original Cold Plunge Tub) is a 105-gallon acrylic and fibreglass lay-down tub sold with the Pro Chiller Gen 2, here in the Cold Only configuration.

The Pro Chiller page rates the chiller at 0.75 HP and 37°F, while comparison cards on Plunge's tub pages show 1/2 HP and 39°F for this configuration.

The chiller needs a dedicated 120 V 15 A circuit, uses ozone and a filter given as 20 micron in one place and 30 micron in another, and connects to the Plunge app over 2.4 GHz Wi-Fi.

The tub measures 66.6 by 31.5 by 26 inches, 144 lb empty on its spec list and 175 lb in the comparison table, and fits users up to 6 ft 8 in. An insulated spa cover, a six-month maintenance kit, a skimmer net, a phone holder and curbside delivery are included.

The Add Heater option ($8,990.00) heats to 104°F; the Pro Chiller alone is $3,990.00 and the tub alone $3,690.00.
