Timeless Elegance: Classic All-White Bathroom

Design a classic bathroom with all-white walls, measuring 2 meters wide by 6 meters long. The shower area features beige tiles and includes an onion-style showerhead with a floor drain placed in one corner. Adjacent to the shower, place a white toilet with a small sliding window above it, positioned close to the ceiling for natural light. Next to the toilet, include a white sink, and above it, a square mirror framed in wood. The bathroom should have a warm, intimate, and cozy ambiance, enhanced by the centrally placed, recessed LED light in the ceiling to provide soft yet sufficient illumination."
