Check PriceFrequently Asked Questions
How cold should a cold plunge be?
Most home cold plunge systems are used well below room temperature; check your unit's manual for its supported range and always ease into cold exposure.
Do I need a chiller, or is ice enough?
Ice-based tubs are more affordable and simpler but require manual ice runs; chiller-equipped systems maintain temperature automatically with less day-to-day effort.
Can a cold plunge go outdoors in winter?
Many outdoor-rated units can, but check the manufacturer's freeze-protection guidance for your climate before leaving a plunge outside year-round.
