No, actually, they’re not. Sevin Coskun’s entry to Treehugger’s Greener Gadgets Design Competition is remarkable in both it’s simplicity, fuctionality and message, but you have to wonder what would motivate someone to install a washing machine in their bathroom… or a toilet in their kitchen.

The Washup combines a washing machine with a toilet, with the grey water from the machine repurposed for flushing the loo. As the average toilet uses 8 litres of water per flush, and most people use the toilet an average of 35 times per week (according to USwitch), the water savings potential is huge.

Here at How Ethical! we can’t help but think it’s all a little impractical, and can’t see many people going out of their way to have this fitted, but the promotion of grey water reuse is commendable, and with a few design tweaks (like plumbing the components into different rooms!) this could be a winner!
