Thinking about home?
Unlimited here is about $150 a month, or about $1,800 a year. A hard-shell plunge with a chiller runs about $4,990 to $7,990, so daily use pays it back in roughly 2.8 to 4.4 years. Plunge less than a few times a week and the membership usually wins. Compare home cold plunges or home saunas.
