Cold plunge cost calculator

Cold plunging is simple. Paying for it is where it gets interesting. A single studio session typically runs $20–$70 depending on your city and whether you book a private suite or a communal session — and monthly memberships at the studios in our directory commonly land between $150 and $300. Do that a few times a week and the habit quietly becomes one of your bigger monthly expenses.

At-home tubs span an even wider range. A DIY stock-tank setup can cost under $200. Inflatable tubs with a chiller bundle run roughly $600–$1,400. Premium all-in-one systems like the Plunge All-In ($7,990) and the Morozko Forge ($9,900) cool themselves, filter their own water, and live indoors or outdoors year-round.

This calculator answers the only question that matters: at your pace, when does a tub pay for itself? Start with the sessions-per-month slider — be honest about your real habit, not your aspirational one. Then pick your studio pricing model: per-session drop-in (the calculator defaults to $45, a typical mid-range drop-in) or a flat monthly membership (default $199). Finally, adjust the three tub price tiers to match tubs you're actually considering.

The result shows your projected yearly studio spend side by side with the break-even month for each tub tier, plus a plain-English verdict. A concrete example: at 8 sessions a month on $45 drop-ins, you're spending $360/month at studios — and a $2,500 mid-range tub pays for itself around month 7. On a $199 membership, the same tub breaks even around month 13. That crossover point is the whole decision.

Two honest caveats. First, a tub isn't free after break-even: budget roughly $10–$40 a month for electricity on chiller models, plus water changes and filters. Second, prices below are planning estimates from typical studio pricing in our directory, not quotes — always confirm with the studio or retailer before spending.
