The Plunge All-In Gen 2 is a 105-gallon lay-down cold plunge with its 0.75 HP chiller built into the tub cabinet, sold here in the Cold Only configuration. Plunge rates it to 37°F, says it holds that in 120°F ambient air, and gives a cooling rate of 10 to 12°F per hour; no BTU/hr figure is published.
It runs on a dedicated 120 V 15 A circuit through a built-in 7-foot cord with a GFCI plug. Water care is ozone plus a filter that the comparison table calls 20 micron and the filter pack listing calls 30 micron, NSF-50 rated.
The tub measures 76.75 by 31.5 by 28.75 inches; the spec list gives 238 lb empty and the comparison table 270 lb. An insulated spa cover, a six-month maintenance kit, a carbon hose filter, a skimmer net, a phone holder and in-home delivery with debris removal are included.
The Add Heater option ($10,490.00) heats to 104°F; Plunge does not state what the shell is made of.
