Design a retro-futuristic spa room with a metallic sheen, where polished chrome accents and geometric patterns evoke a sense of nostalgia for a bygone era. Walls adorned with a swirling pattern of turquoise and silver hues, reminiscent of vintage sci-fi illustrations. The floor is covered in a plush, emerald green carpet that contrasts with the space's metallic tones. A floor-to-ceiling LED light installation in a geometric shape, with pulsing blue and purple hues, casts a mesmerizing glow. A curved, chrome-plated tub sits atop a raised platform, surrounded by a crescent-shaped seating area upholstered in a bold, geometric pattern. Soft, retro-inspired seating areas with chunky, chrome frames invite relaxation, while geometric-patterned throw pillows and a faux fur rug add warmth to the space. The air is filled with the scent of eucalyptus and citrus, and ambient music plays a hypnotic, electronic soundtrack.
