A cold plunge on this page means a tub made to be filled with cold water and sat in. The Ice Barrel 400 publishes its dimensions and water volume. It does not include a chiller in the spec we read.
Ice Barrel no longer sells the 400 (checked Nov 5, 2026). The cold plunges page has its successor, the 500, and tubs in stainless steel and cedar.
