The Renu Therapy Cold Stoic 2.0 is a cold-only plunge tub with its 0.25 HP chiller, filter and ozone system built into one body, in Meterous Black with a California Redwood deck.
Renu rates it to 39°F, and it holds 95 gallons in a 40 by 25 by 31 inch tank inside a 70 by 33 by 35 inch body with 4 inches of perimeter insulation. It plugs into a standard 120 V 15 A outlet, uses simple built-in controls, and comes with a matching step stool and a protective lid.
It weighs about 350 lb on its page (365 lb dry on its cut sheet) and ships curbside. Ambient lighting is an option at $10,319.00 and a Pacific Cedar deck at $10,199.00. The tub carries five years and the chiller one year; an extended chiller warranty to five years costs $299.99.
