Transform the uploaded empty bathroom into a sophisticated, photorealistic dark bathroom. Preserve the exact room dimensions, architecture, door and window openings, plumbing locations, camera angle, and perspective.
Use matte charcoal-black porcelain tiles with subtle stone textures, a dark oak floating vanity, a black stone countertop, a charcoal vessel basin, matte black fixtures, and a wall-hung black toilet where existing plumbing allows. Add a large backlit mirror and a clear glass shower partition only if space permits.
Balance warm concealed lighting and recessed ceiling lights with natural window light. Keep dark surfaces richly detailed and clearly visible. Use realistic textures, reflections, proportions, and practical spacing. Add minimal, coordinated accessories.
Make it look like a real architectural photograph of the same room after renovation. Do not enlarge the room or move structural elements. No people, text, logos, watermarks, or artificial CGI appearance. Return one finished image of the redesigned bathroom.
