FAQs
How does it work?
HomePlunge rolls up to the edge of your bathtub and the hose-arm dips into the water. The chiller's internal pump will draw the bath water out, chill it to your set temp, and cycle the chilled water back into the tub.
How long does it take to cool?
30 minutes to 1 hour for most users.
Can I schedule it to turn on and off?
Scheduling is a great way to plan ahead and can be done with the Tuya Smart Home app.
How much will my electric bill go up?
Unlike the other cold plunges that need to run 24/7, HomePlunge only runs 1-2 hours a day. Turn it off when you're done cold plunging and come back the next day.
I'm worried about condensation and mold
Rest assured, condensation regularly occurs with every day hot shower and bathtub use with the temperature delta between hot water and ambient air. HomePlunge is no different. Mold is prevented from having air flow in the bathroom. Best practices include keeping the door open and running the exhaust fan during use to maximize air flow.
What's your warranty?
One year manufacturer's warranty
Can I finance it?
Use Shop Pay at checkout to see your available finance options.
Does it work on standard power?
Yes. 110V 15A standard electrical outlet.
Does it require custom plumbing or installation?
No. HomePlunge is 100% modular and does not require any installation. Set up takes literal seconds.
