Hack Your Toilet and Save Water

We have shown toilet lid sinks before; it makes so much sense to get a wash out of the water before it goes into the toilet tank. They are common in Japan and there are a couple of versions that you can buy, but Gregory Lavoie provides instructions in how to build one yourself. He says "I wanted this instructable to be simple enough that anyone could build it with basic tools and materials. I also tried to be material conscious with this project in that: many of the materials are recycled from other things (sheet wood and copper tubing) or second hand (metal bowl), and that it is put together using screws and friction fittings so when the sink has finished serving its purpose it can easily be taken apart and the parts can be recycled." ::Instructables via ::Lifehacker
