i would add the bulkhead directly into the main prompt so archsynth doesn t accidentally tile or clad it scene create a magazine quality photorealistic rendering of a luxurious spa inspired primary ensuite shower and sauna retreat the overall atmosphere should feel deeply calming sophisticated warm and restorative with natural materials muted earthy colors and beautifully restrained detailing the design should embody quiet luxury and high end wellness retreat aesthetics creating the feeling of a private boutique spa within the home preservation of existing layout use the existing image or model as the exact geometry and composition reference maintain all existing shower dimensions wall locations shampoo ledge stub wall configuration bench location sauna location bulkhead location and dimensions plumbing locations glass placement openings ceiling height camera angle and perspective do not relocate resize redesign or reinterpret existing architectural elements the rendering should function as a finish material lighting and styling study only shower feature tile above the existing shampoo ledge stub wall install a sophisticated mid tone muted green tile the green should feel earthy calming and natural rather than bright or saturated with muted sage moss and soft grey green undertones and gentle natural variation the tile should feel handcrafted and luxurious while remaining calm and sophisticated bulkhead maintain the existing bulkhead exactly in its current location size depth and configuration the bulkhead is to have a smooth painted finish and is not to be tiled clad in stone wrapped in marble or finished in wood finish the bulkhead in a soft warm neutral painted color that integrates quietly with the surrounding walls and architecture the painted bulkhead should provide a visual pause above the richer shower materials and maintain a clean refined architectural appearance shampoo ledge stub wall maintain the existing shampoo ledge and stub wall exactly as designed the ledge should feel integrated into the architecture rather than appearing as a recessed niche style the ledge minimally with sophisticated spa products in refined bottles shower bench wrap the shower bench completely in a beautiful green and white veined marble look stone the material should feature soft white and cream undertones muted green veining gentle grey green movement and sophisticated natural variation the marble should wrap cleanly across the top front and visible sides of the bench creating a monolithic custom stone appearance shower floor ensuite flooring finish the floor in a soft white and warm cream textured tile with subtle natural variation and a matte or honed appearance avoid stark bright white or cool grey flooring the floor should provide a soft calming foundation for the richer green and oak materials shower glass maintain the existing shower glass configuration the enclosure should feel seamless and frameless allowing uninterrupted views of the green tile marble bench and surrounding spa materials keep the hardware minimal and sophisticated plumbing fixtures finish all shower plumbing and hardware in a luxurious soft brushed nickel this includes the shower head handheld wand controls shower glass hardware handles and other visible metal details the brushed nickel should have a soft satin appearance rather
