With a freestanding tub, Jason Wu for Brizo tub filler, and warm shade palette, Sophia Bush’s Hollywood bathroom is soothing and sensational in equal measure. When it involves design, a guest bathroom doesn’t have to play second fiddle. In this Hudson Valley, N.Y., residence, designer Sheila Bridges lined this area with artwork from Earl Swanigan, Waterworks’ finishings, and partitions lined in a customized design by Bridges herself. Ernest de la Torre brings an unexpected color mixture to this Bel Air (L.A.) bathroom. Here, he pairs Schumacher’s yellow grass cloth wall covering with a custom—and undeniably striking— Brazilian quartzite sink.
