The LED Susan by Royal Toto is a smart faucet that does the thinking for you. This innovative bathroom faucet features a color temperature indicator that lets users know whether the water is cold or hot without getting burned. The modern faucet features a contemporary look with an LED-lit black button that turns blue when the water temperature is less than 26 degrees, red when the temperature is more than 38 degrees, and green anywhere in between. Within three seconds of heating up or cooling down, you’ll know it just by viewing the indicator. The faucet’s high-polish chrome finish and chic shape makes it an interesting addition to any modern bath. Royal Toto.
