A hallmark of Shingle-style architecture, this guest bathroom’s oval window was fitted with a Roman shade made from Fabricut’s Tella Birch linen. Schumacher’s cornflower Haruki Sisal wallcovering and a circa-1960 Eero Aarnio wicker Juttu stool, purchased at Bloomberry in the Netherlands, impart texture and warmth. The polished nickel Vendome Single sconces are by Visual Comfort & Co.
