Arlington clients contacted Rebecca Penno for an overhaul of their primary bath (above). The designer conjured a bright and airy feel via cabinetry painted a light-neutral hue and pale-gray marble tile, which clads both the floor and shower enclosure. “Our preferred surface material in a primary bath is natural stone,” Penno relates. “It’s the most organic way to create a one-of-a-kind space, because no stone is like the next.” A heated floor imparts a luxurious touch.
