The Conoflat shower tray is for modern and design-oriented bathrooms, its manufacturer Kaldewei says. This is code for “the product is expensive.” Cost aside, the eye-catching unit is sleek and inconspicuous and offers a level of hipness that cannot be achieved with a traditional shower pan. Made from steel enamel, the tray is extremely flat and extra-shallow so it’s hard to tell where the floor ends and the shower begins. It even has an enamel steel cover to hide the unsightly drain. The unit comes in 17 dimensions so it will fit most baths and eight colors. Priced from around $1,400. www.kaldewei.com.
