Conoflat is no ordinary shower tray. The product from Ahlen, Germany–based Kaldewei is made from 3.5 millimeter enamel steel and has an extra-shallow design that allows the pan to sit flush with the finished bathroom floor. Designed by Sottsass Associati in Milan, the tray also features a square, enameled cover that furthers the unit’s architectural look. It’s available in 17 dimensions and three colors.
