With each flush of your commode, clean water that would otherwise go straight down the toilet is first routed up through a chrome gooseneck spigot to dispense pure water for hand washing. The Toilet Lid Sink installs easily without tools, is attractive for any bathroom and is a great space saver. Shuts off automatically. Porcelain-like white plastic replaces your existing tank top and adjusts to fit standard toilets up to 8in wide and 18-22in long. Built-in soap dish.
