Cold Plunge

Choose a cold plunge — tub type, chiller capacity, and temperature control.

Ice baths from bags work but require constant ice purchasing and imprecise temperature. A dedicated cold plunge with a chiller maintains consistent temperature, filters the water, and eliminates the logistics. This page covers what separates a $300 inflatable from a $3,000 chilled rigid tub — and whether that gap is worth it for your use case.

Guides

Practical cold plunge buying content — tub construction, chiller specs, temperature ranges, filtration, and what ice baths actually cost to run.

Buying guide How to choose a cold plunge: tubs, chillers, temperature control, and filtration Inflatable vs rigid tub construction, chiller capacity sizing, achievable temperature ranges, filtration requirements, insulation, and the honest economics of ice vs chiller over time. Troubleshooting & repair Why your chiller won't get cold, won't turn on, or can't hold temperature — it's flow, airflow, and a heat budget, not a dead compressor A chiller can't make cold — it only moves heat. Read "won't get cold," the silent-after-plug-in delay, and the hot-day plateau to the cheap fix (usually a $15 filter or a better spot), grounded in maker manuals and refrigeration basics.

Why this page exists

Cold plunge content skews toward aspirational lifestyle content or heavy-handed affiliate reviews. Neither tells you what chiller BTU capacity you actually need to hit 50°F in a given tub volume in your climate, or what filtration means for water change frequency.

The practical specs — chiller sizing, filtration capacity, insulation R-value — determine whether a unit works as advertised in your environment. Those details belong in the buying decision, not discovered after delivery.
