Not feeling particularly, well, flush? Take a seat: You can save yourself a couple of hundred bucks by modding your own toilet/sink combo-one that redirects the flow of fresh water so you can wash your hands as the cistern refills.

Most of the materials used in this Instructable were reused or recycled; screws and friction fittings were used so you can take the sink apart at a later date and recycle all the parts. And if you're still confused about the mechanics of the setup, the above video will elucidate, but consider yourself warned. ::Instructables
