駅の公衆トイレ：高頻度利用と迅速な清掃

Design a railway station toilet built for very high frequency use and rapid cleaning between peaks. Show a layout with a completely separate entry and exit so passenger flow is one-way, each opening wide and door-free with a baffled screen for privacy. Detail the cubicles as a long run with an occupancy indicator light above each, and a luggage shelf inside every cubicle at 900 millimetres because passengers carry bags. Show the wash counter as a continuous seamless run with sensor taps, integrated soap and dryer in a single unit per position, so a user completes the sequence without moving — the single biggest reducer of queueing. Detail the floor as a large-format porcelain with a fine texture, falling to concealed drains, and the walls in the same material to full height. Show a cleaner's cupboard opening directly off the space with a hose point. Detail the finishes as light and hard with one strong accent colour on the cubicle doors for wayfinding. Include commuters with luggage. Photorealistic, bright, efficient, eye-level view along the counter.
