A cold plunge is a big purchase. These are the five things that separate a great one from a headache.
1. Chiller or ice?
Ice-only tubs cost less upfront but need bags of ice every session. A chiller keeps water cold on its own and pays off fast if you plunge often.
2. Cooling power
Hot climates, outdoor setups and multiple users need a stronger chiller to hold temperature. Putting one outside? Read Outdoor Cold Plunge in Hot Weather first.
3. Filtration and sanitation
Look for a filter plus UV or ozone sanitation so you're not draining and refilling constantly.
4. Size and fit
Measure doorways, stairs and the final spot. Check the filled weight if it's going on a deck.
5. Cover and warranty
An insulated, lockable cover saves energy and keeps kids and pets out. Compare warranty length on the chiller.
