Turn your shower into a fun, mood-setting experience with the BathSelect 20" LED Rainfall Shower Head. As soon as you turn on the water, the built-in LED lights illuminate automatically, creating an ambient atmosphere. The color of the LEDs changes based on the water temperature, giving you a visually engaging shower experience. Best of all, the lights are entirely self-powered—no batteries required! The energy is generated by a built-in dynamo that uses the water pressure to power the LEDs, making it both eco-friendly and convenient.
