My friends Bill & Liz have a great old house in Oakland, CA. The kitchen bathroom was installed in (literally!) a closet, so there was only room for a toilet or a sink, not both. This ingenious product solved that dilemma. The Toilet Lid Sink
refills the toilet tank by flowing the fresh water (yes, it’s right from the pipe) through a sink faucet and bowl atop a lid that replaces your regular lid.  A built in soap dish holds the soap, and the water flow lasts as long as it takes the toilet to fill. Saves space and water, and turns your commode into a very unusual conversation piece.
