transform this conceptual powder room model into a high end photorealistic interior render while maintaining the exact room dimensions layout camera angle and proportions shown in the reference image this is an extremely narrow powder room so do not make the room appear wider deeper or larger than it actually is preserve the tight spatial feeling all walls including the side walls and back wall are wrapped in the same continuous watercolor inspired wallcovering the wallpaper features soft overlapping washes of pale blue misty sage warm grey and off white with subtle texture and translucency ensure the pattern wraps naturally across all walls with realistic seams and material depth do not introduce dark painted side walls the hanging fixture is not a pendant light it is a ceiling mounted faucet suspended from the ceiling similar to the attached reference image replace the current interpretation with a realistic matte white ceiling mounted sink faucet featuring a slim cylindrical stem descending from the ceiling and terminating in a clean modern spout positioned directly above the sink basin it should read immediately as plumbing not lighting the sink is a matte white fluted cylindrical pedestal sink with realistic ceramic texture subtle shadows and soft highlights the toilet remains a standard glossy white porcelain toilet with realistic reflections and ceramic sheen maintain accurate fixture proportions relative to the room and user silhouette the mirror should be a realistic vertically oriented oval mirror with proper thickness subtle reflections and realistic edge detailing the floating wood shelves should remain simple and minimal with realistic wood grain and accurate scale improve all materials with realistic rendering qualities including texture depth reflections ambient occlusion contact shadows and physically accurate lighting add soft indirect daylight illumination with realistic shadow gradients create a calm elegant spa like atmosphere remove the blue sky background grey void and any exterior abyss visible around the room the image should appear as a finished interior rendering with enclosed walls ceiling and realistic architectural boundaries clean up all model edges eliminate sketch like outlines and replace them with realistic construction details maintain the exact camera view fixture locations room dimensions ceiling height and overall composition do not move resize or redesign the layout the goal is to convert the existing design into a believable luxury residential powder room render while preserving the original design intent and proportions exactly
