A cupboard with sealed bottom. Luckily the dish washing machine reduces the need of the cupboard.
It's strange how come this innovation has not become popular globally. Maybe it's due to the big kitchen dealers and their bad adaption of the cupboard: for example Ikea and Kvik have sealed the bottom of the cupboard - which means that the water stays in the cupboard and air cannot flow freely. Which again leads into one thing only: mold.
