I don't know whereabouts you are, but here in the UK, such an item is
commonly available as a shower extractor fan with a built in light

It is hooked into the normal lighting circuit, and as long as the light is
on, the fan runs. When you switch off the light, the fan continues to run up
to an adjustable time of 20 minutes
