Cold Plunge Tub, 110 Gal
The pragmatic on-ramp before you commit to a $5,000 chiller unit. The insulated walls hold cold water for hours, the footprint suits a garage or patio, and at this price you can find out whether you'll actually keep the habit. Reality check: without a chiller you're managing ice, so it's a commitment, not a plug-and-plunge. Ease in — cold exposure is a stressor, and more is not better.
