Eco bath - reuse your water

Eco Bath by Jang Woo-seok » Yanko Design

"Here’s a lovely simple system that makes use of the fact that toilet water never needs to be as clean as it usually is. The “Eco Bath” concept uses 50% reused water and 50% new water for a toilet system half-ways to nature friendly."

The systen recycles the used water of the wash-basin, neat.
