FAQs
Have a question ? We are here to help.
How long does the HomePlunge take to cool your bath?
Cooling time depends on how warm your tap water is and how cold you want the plunge. The H3 cools at 1–6°C per hour (manufacturer specification), so it will take longer in warmer climates and in summer. You can schedule it in the app so the plunge is ready when you are.
What are the benefits of cold plunging?
Cold-water immersion causes blood vessels near the skin and extremities to constrict, helping the body conserve heat. When you warm up again, those blood vessels dilate and peripheral blood flow increases. Research also suggests that cold-water immersion can help reduce muscle soreness and support short-term recovery following exercise.
Cold exposure also activates the body’s natural stress response, temporarily increasing physiological arousal. Some research suggests that cold-water immersion may influence the body’s response to stress and support feelings of wellbeing, although evidence for longer-term effects on cortisol and mental health is still developing.

How is HomePlunge more energy efficient than other cold plunge alternatives?
The H3 only runs when you schedule it, rather than keeping water cold around the clock. It runs on a standard 240V outlet and draws up to 9A.
Can I pre-schedule a chill?
Yes. Scheduling is available via the Tuya smart app — set it before leaving for a workout and come back to a ready plunge.
