About Cold Therapy Lab
Cold Therapy Lab exists to make one decision easier: which cold plunge should you actually buy? The cold therapy space exploded over the last few years, and with it came a flood of look-alike tubs, confusing chiller specs, and thin "best of" pages that recommend whatever pays the most.
We do it differently. For every product we cover, we dig into the real specs — temperature range, chiller power, filtration, materials, footprint, warranty — and lay out honest pros and cons for different buyers: athletes, biohackers, small-space apartment dwellers, and budget-first DIYers.
How we make money
Cold Therapy Lab is free to read and reader-supported. When you buy through some of our links, we may earn an affiliate commission at no extra cost to you. This never changes our verdicts — we'd rather lose a commission than send you to the wrong tub. See our full affiliate disclosure.
A note on safety
Cold water immersion is a powerful tool, but it carries real risks (cold shock, blood-pressure spikes, after-drop). Nothing on this site is medical advice. Talk to a qualified healthcare professional before starting cold therapy, especially if you have a heart condition.
