Setup, start to finish

Six steps. That is the whole setup.

No plumbing. No remodel. The chiller rolls up to the bathtub you already own, the arm goes over the rim, and it plugs into a standard outlet.

Roll it up to the tubIt is on wheels. Nothing is plumbed in and nothing is permanent.
Quick-connect the hose-arm into the chillerOne arm carries both hoses, and they stay concealed inside it.
Dip the arm into the waterThe arm bends and stays where you set it, so it fits over the rim of the tub you already have.
Plug it in. Turn it on.A standard household outlet. There is nothing to wire.
Set your temperatureSet it on the unit or schedule it from the Tuya app. The H3 goes down to 34°F.
Get inThat is the whole setup, and it takes minutes.
