This house is located only steps from the beach in the famed Hamptons, so architect Frederick Stelle made certain to exploit its million-dollar views of the Atlantic Ocean. The master bath juts out from the house and is encased in floor-to-ceiling glass, capturing plenty of natural light along with that panorama. A soaking tub commands the best views, while the shower features a half wall that maintains sightlines but offers a modicum of privacy. The space is outfitted in a rich palette of “carefully cerused oak” millwork, Calacatta gold marble countertops, and limestone floors and shower tiles.
