An indoor, dimly lit spa environment is depicted, specifically the thermal area of the REGENSIS Spa & Wellness at the Hyatt Regency Sofia, located at Vasil Levski Square, Sofia, Bulgaria. The scene centers on an irregularly shaped pool filled with dark blue water, featuring internal green accent lighting along its perimeter. The water's surface reflects ambient light, displaying ripples. The pool is bordered by a dark, possibly stone or tiled coping. The foreground floor consists of large-format dark tiles, visibly wet with numerous reflective puddles. A low, curved partition wall separates the pool area from the floor, illuminated by a continuous strip light integrated into its base. A prominent dark, rectangular pillar stands on the left, extending from floor to ceiling, equipped with a curving metallic handrail that descends into the pool. A gold-colored informational plaque is affixed to this pillar. Two additional narrower, dark, possibly mosaic-tiled vertical structures are positioned further back. The walls are clad in dark, three-dimensional geometric panels, possibly metallic, which are dramatically lit from above to highlight their textured relief. A decorative overhead fixture, comprising multiple suspended spherical lights, hangs from the dark ceiling towards the rear of the pool. No individuals are present in the depicted scene.
