Add a concealed warm LED strip light behind the beige marble panel(vertically) behind the bathtub. The LED strip must be oriented to face away from the marble surface, creating a soft indirect backlighting glow (halo effect) rather than illuminating the marble directly. Use a warm color temperature (2700K3000K) for a cozy ambient feel. Do not change any other elements in the imagekeep all materials, layout, lighting, textures, and camera settings exactly the same.
