Featuring a stunning waterfall spout with a built-in Led, this faucet changes color by detecting water temperature for both visual appeal and safety. Blue indicates cold water (0-30degree(s)C), green signals warm water (31-42degree(s)C), red shows hot water (43-52degree(s)C), and when water is extremely hot, the red light flashes on and off to warn against scalding. This single-hole bathroom sink faucet is easy to install, designed to fit 1 or 3-hole sink installations with a 6-inch deck and includes two standard supply lines. The single lever handle allows effortless adjustment of both temperature and flow rate, making daily use simple and convenient. The Led lights are powered by 4 Aa batteries (batteries not included). Whether you're upgrading a powder room or a master bath, this faucet combines the elegance of a waterfall stream, the safety of temperature-indicating lights, and the practicality of easy installation for a truly modern and functional bathroom experience.
