Luxury Spa Bathroom with Indoor Pool

Create a photorealistic ultra-luxury modern spa bathroom interior in a wide horizontal 4:3 architectural render. The room is clad almost entirely in warm gray limestone or travertine, with seamless large-format stone floor and wall slabs, soft beige-gray tones, and calm resort-like atmosphere. In the left foreground place a large freestanding oval white bathtub with a minimal brushed-metal floor-mounted faucet; beside it add exactly 1 small round dark stone side table holding exactly 4 bath items: 2 amber pump bottles, 1 small jar, and 1 folded towel or soap dish. Along the left wall create a long floating stone vanity with under-cabinet warm LED lighting, two tall rounded-rectangle backlit mirrors, minimal faucets, and sparse decor including small bottles and branches in vases. In the center background show a glass-enclosed shower with transparent frameless panels, a rainfall shower head pouring visible water from the ceiling, a recessed niche with toiletries, and three wall-mounted controls or outlets. Slightly right of center include a separate toilet alcove behind a stone partition with a wall-hung white toilet, a small shelf, and a towel. On the right half of the image create an indoor rectangular turquoise plunge pool running from foreground to background, with clear rippling water, submerged steps at the near end, a slim metal handrail, and continuous underwater edge lighting. Beyond the pool, use floor-to-ceiling glass walls revealing a private courtyard garden with exactly 1 slender tree, low green plants, and stone walls; include reflections on the glass. Near the back right add exactly 1 cushioned lounge chair with pillows in front of a softly lit vertical ribbed wall panel. The ceiling should be smooth and sculptural with a large rounded rectangular cove light glowing warmly, small recessed downlights, and thin black linear ceiling slots. Use warm ambient lighting, hidden LED strips, soft reflections, balanced natural daylight from the garden, cinematic architectural photography, eye-level wide-angle lens, crisp details, realistic materials, no people, no text, no clutter. Optional customization: make this a {argument name="room type" default="ultra-luxury modern spa bathroom"} with {argument name="stone material" default="warm gray limestone or travertine"}, a {argument name="pool color" default="turquoise"} indoor plunge pool, {argument name="lighting mood" default="warm ambient resort lighting"}, and a courtyard containing {argument name="courtyard tree" default="one slender tree"}.
