The Spanish company Roca has won several awards for its eco-friendly design W+W that combines sink and toilet. W+W reuses the water from the wash basin for the water closet. The water that falls into the wash basin gets filtered before being recycled to prevent the formation of bacteria and unpleasant odours.
The L-shaped design that forms a single body provides great freedom of movement, perfect for small space living.
Roca claims that their design can reduce water usage by up to 25% compared to a standard toilet.
The design was created by the Roca Innovation Lab and designed by Gabriele and Oscar Buratti.
