For cold, start with the Ice Barrel 300 or 500 before paying for automation. For infrared heat, the Erommy two-person sauna is the strongest under-$2,500 cabin option currently on this shortlist.
Cold-plunge shortlist
Ice Barrel 300 — $1,149.99
A shorter, fully insulated tub with chiller ports. Ice Barrel lists a 35.5″ width and height, 77-gallon capacity, 61-pound empty weight, and fit for most users up to six feet.
Ice Barrel 500 — $1,749.99
The larger upright model adds an interior seat and built-in steps, fits users up to 6′9″, and measures 57.6″ × 30.7″ × 42.1″. At about 900 pounds full, placement still requires structural judgment.
Plunge Air — $1,190 tub-only listing
The inflatable Plunge Air is the lowest-cost entry on Plunge’s current product surface, but active chilling requires additional hardware. Compare the total package—not the tub price alone.

Budget traps
- Chiller, pump, hoses, covers, steps, and water treatment can change the real cold-plunge price.
- Electrical work, delivery path, flooring protection, and ventilation can change the real sauna price.
- Sale prices and financing can hide the total paid over time.
