For those who like this sort of thing, it's 1000 iterations, built-in denoiser on at 990 iterations. Light source is a bright sunlit sky HDRI outside a fully enclosed room with a single window and a single emissive surface light just out of the camera's view to the left. The water is three stacked planes, not a full volume so it rendered pretty quickly, the faint steam effect is also a simple textured plane. The models skin is Bambina 8, and her body is GF8 with a bunch of random morphs.
