A floating duck bath thermometer with a large LCD display that gives an instant digital temperature reading and flashes red when the water is too hot, removing the guesswork from getting the perfect bath. Simple to use, just tap against your palm to turn on and float in the bath, it is as useful for adults wanting to get an Epsom salt bath to the ideal temperature as it is for families with young children. Worth keeping the battery cover dry after each use to help with longevity. Recommended as an inexpensive, practical, and rather fun bathroom essential for anyone who takes their bathing seriously.
