Take the guesswork out before getting in. The water-powered Temp2O LED digital temperature display shows the temperature of the water in your shower. Three color indicators signal different temperature ranges for an easy, visual indication of the water temperature. Blue represents below 80 degrees, magenta is between 80 and 110, red is greater than 110. Enjoy the convenience of jumping in the shower when the temperature is right for you and the peace of mind that the water temperature is a safe temperature for children and pets. Delta is committed to supporting water conservation around the globe and has been recognized as WaterSense Manufacturer Partner of the Year in 2011, 2013, and 2014. Upgrading to a new Delta showerhead is a great weekend DIY project. No special tools required.
