Combining both function and eco-friendly design, the Spanish Innovation Lab - Roca, has created a neat L-shaped sink and toilet combo. By combining the two elements of a bathroom house owners can save a significant 25% of the water that is normally used in the bathroom.

This would be great for some of the older buildings in Europe which have small apartments with smaller bathrooms and with this unit you save some serious space. Only obstacle is the EUR 2,731 price tag that comes with it.

None the less it's a great example of using design to solve everyday problems i.e. space and waste water. Two thumbs up to the Spanish!
