This Instructable is a step by step description of the process of adding a sink to the top of a toilet allowing the use of the clean water before it goes into the bowl.
Water is a precious resource and our everyday lives are immersed in consuming it. The average toilet uses excessive amounts of water. This hack allows you to minimize some of that water consumption.
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.
Step 1: Materials
9inchx20inch piece of sheet wood
Small plastic funnel
Copper tubing half inch outside diameter
Metal bowl approximately 8 inch diameter
4 feet of Vinyl tubing 1/8 inch inside diameter
4 "L" brackets and small wood screws
Silicone latex caulking glue
Steel binding wire
1/2inch spade drill bit
1/8inch drill bit
Hole saw 3 inch
