The staircase features a smooth, spiral curve that creates a harmonious visual connection with the undulating ceiling design. The steps are crafted from white natural marble with a fine, smooth texture, paired with translucent, curved glass railings and dark metal posts—a perfect balance of contrasting materials. Spot lighting is integrated into the tops of the posts, casting a soft, non-glaring glow. The overall design is clean and crisp, preserving the sense of order characteristic of modern minimalism while also aligning with the relaxed and healing atmosphere required for a spa space.
