Heads up: some links here pay us. If you buy through an EcoFlow or eufy link we may earn a commission, at no cost to you (that's Awin, in some countries). Amazon and other shop links pay us nothing right now. I haven't tested these products myself unless the page says so; the picks come from the specs and listings, and I'll tell you when I'm not sure.

Frequently Asked Questions
For an 80-100 gallon tub, roughly 40-60 lbs of ice is a common starting point to chill tap water; check the maker's guidance. Insulated tubs like the Ice Barrel 300 require less because they retain cold better. The Cold Pod may need a full 60 lbs due to minimal insulation.
Rigid tubs like the Ice Barrel 300 and Plunge Evolve handle outdoor placement well. Inflatable options like the Cold Pod should be brought indoors during freezing weather to prevent material cracking. In winter months, you may not need ice at all since ambient temperatures handle the cooling.
