Incorporating commercial trends in the home kitchen is one thing, but Adamstein and Demetriou didn't stop there. “We were renovating our house at the same time that we developed a spa/gym concept called Somafit,” Demetriou says. Tired of running in different directions to exercise at the gym or to relax at the spa, the architects merged everything they needed into one spot—both for their commercial venture and for their own master bath.

A skylight angled to catch morning rays sends bathers a wake-up call, while an etched-glass wall between shower and master bedroom conveys the golden light of afternoon. Watery-green glass walls, beige limestone tiles, and a cream travertine counter establish a soothing tone for long soaks or a refreshing rinse under a rainfall showerhead.

“We're advocates of warm, comfortable spaces,” Demetriou says, “and we feel contemporary design can achieve that through lighting and material palette.”

Corralling toiletries into tidy niches quiets the visual noise, and a floating vanity with mirrored cabinets above keeps other necessities out of sight. It is, says Demetriou, “a sculpted space with an evocative atmosphere.”
