Design goal: Before the home’s construction, the owners were clear: They wanted a contemporary but comfortable vibe throughout the house, and the master bathroom was no exception. “They wanted lots of natural light, even though the bathroom faces the street,” says John Knudson, AIA, of Knudson Gloss Architects (Kgarch.com) in Boulder. Ceiling-high rectangular windows solved that problem. How did Knudson keep the space contemporary and warm? “Carrera marble, which is cool but not cold, is the predominant material,” Knudson says. And mixing such classic elements as marble, wainscoting and a neutral palette with minimalist lines keeps the room inviting. The homeowner, an artist and an art dealer, wanted a place to display modern art (note the Robert Rauschenberg above the soaking tub), making this bath simple yet elegant, classic yet contemporary.
