Tiny Palace

“I wanted it to feel like a jewel box,” says designer Andrew Brown of this bathroom that’s accessed through a jib door. He coupled richly veined Calacatta Arabescato marble with a warm mural wallpaper; the unlacquered brass showerhead will darken over time. Marble: Triton Stone, fabricated by Will Casey/ Cottage Supply Company. Wallpaper: Procession, Iksel for Schumacher. Plumbing and fixtures: Waterworks.
