This has been shown on HGTV, the Toilet topped sink from Sink Positive offers a simple way to use grey water from your toilet. After you flush, the touch free faucet will deliver the fresh water and let soapy water drain into the toilet tank for the next flush. I found the above information in this magazine. It is not often I find a product that is so interesting as to want to share it here. I’m thinking this would be a perfect solution to the need of a half bath in my AZ. home. I’ve seen something like this before in Motorhomes and thought what a concept!!!!! Now homeowners can use the same idea and be green at the same time.
