One chiller powers both cold and warm modes. You are not buying or storing two separate units.
App scheduling lets you set cold mode for the morning and warm mode for the evening without touching the unit.
The built-in 3-stage ozone sanitation system handles water cleanliness on its own; no chemicals to measure or add.
Double-walled marine-grade PVC shell holds temperature in both cold and warm modes without working the chiller harder than it needs to.
No plumbing needed; fill with a hose, plug into a standard wall outlet, and it is ready to go.
The insulated lid keeps the water at your set temperature between sessions so you are not waiting every time.

What Cold Water Immersion Does for Your Body

Reduces Muscle Soreness

Cold water immersion constricts blood vessels and reduces inflammation in muscle tissue after intense physical effort, helping you feel ready sooner.

Sharpens Focus and Alertness

Cold exposure triggers the release of norepinephrine in the brain; a natural driver of alertness and attention that can last several hours after each session.

Builds Mental Strength

Choosing to enter cold water is a deliberate act of discomfort. Done consistently, it trains the part of the brain that controls impulse and stress response.
