干湿分离与防水：卫浴的基本盘

Render a Taiwanese bathroom detailed around correct waterproofing and a clean wet-dry separation. Show a fully enclosed shower area with frameless clear glass to the ceiling and a slim pivot door, its floor falling to a linear drain set against the wall so the fall is imperceptible underfoot. Detail the threshold as flush, with a discreet upstand hidden beneath the tile and a fine metal strip marking the boundary. Show the dry area with a wall-hung vanity, a wall-hung toilet with concealed cistern, and a large mirror cabinet with integrated lighting. Use large-format porcelain tile with minimal joints throughout, running the same tile in the wet and dry zones so the room reads as one volume divided only by the glass. Include a recessed niche in the shower with a concealed light, a heated towel rail in the dry zone, and a ceiling extract fan set into a slim service plane with a matching grille. Show a small operable window with obscured glass. Bright even lighting with a warm strip behind the mirror. Photorealistic, wide view from the doorway.
