how to light a indoor toilet scene with not much light

Hi, i have an indoor in public toilet scene that i want to light. it’s pretty much like when you go to the toilet in the morning and the toilet tiles seem a bit white-grey and light-blue to you. there are shadows near the sink and toilet doors. I have tried a few things, using directional light and sky sphere and lower the intensity down but doesn’t quite fit. How to light it in a better way?

Is the light coming through wall windows, or do you have a ceiling window?
I would use a pointlight and set the attenuation to encompass the entire room and set it to a rather low intensity and give the lightcolor a slight blue tint.
You can also experiment with either stting the light to not cast shadows , or place some smaller fill lights where you dont want shadows (like under the sink)…
