Indigo Bath House

Photograph a small Japanese-inspired bath room with deep indigo tiles, a low cedar soaking tub and a tall narrow frosted window. The window admits cool morning light that falls in one vertical band, revealing gentle steam above the water. A folded white towel sits on a plain wooden stool; a tiny copper dipper catches the only warm reflection. Leave most of the tiled wall empty to emphasize the low tub and room height. Show real grout, uneven glazed tile reflections, saturated wet wood and subtle condensation. Balanced quiet geometry, no person, no text, no hotel branding. Generate exactly one finished image.
