Hi,
Give this a shot - change your preset to medium (5 levels), and make sure it's not set to "Render by Time". Also - put a floor into the model to bring more indirect light underneath the sinks and to ground the people models. Post the results here. The way these indirect illumination renderers usualy work is by path-tracing photons from your light source as they bounce through the scene. Rendering by time, it should keep refining - but by rendering by levels, when it reaches the last level the renderer it should average the results (sort of like Mental Ray's Final Gather).
Hope this helps - if so mark it solved, and if not just post again and we'll take another look.
