Kestly Floating Plunge Thermometer — Built-in Timer | Waterproof IP67

A waterproof floating thermometer with a built-in session timer, designed specifically for cold plunge and ice bath use.

Knowing your water temperature before you step in — and tracking how long you have been under — is one of the simplest ways to keep a cold plunge practice safe and progressive. Most kitchen or pool thermometers are not built to float in a tub, read clearly through condensation, or survive repeated submersion. This one is.

What it does

• Displays water temperature continuously on a clear digital face readable at arm's length
• Built-in countdown and count-up timer supports structured session management
• IP67 waterproof rating withstands full submersion and repeated ice bath conditions
• Floats upright in any plunge tub — no mounting, no clips, no setup required

Who it's for

Anyone running a regular cold plunge practice who wants reliable, at-a-glance data without the complexity of a connected device. Equally suited to beginners calibrating their first sessions and experienced practitioners tracking progressive cold exposure over time.
