Window between two rooms

Yes, it depends on what kind of room it is. We are getting a skylight above the bathroom doors towards the hallway and it will be approximately this size. I do think it helps with lighting the hallway. You probably won’t be able to read a book by it, but it’s enough so that you’re not standing in the dark during the day.

Common next to the room door to the living room to the hallway, e.g. in apartments. Also above doors, yes. Nowadays often used in internal bathrooms

I think something like that is great, but I don't have it myself

Ok, one more thing, since it has already made its way onto the internet anyway. My clients tell me something different when I make their facility public

Looks great. Unfortunately, we didn't come up with this idea. We could have installed a skylight from the utility room to the hallway. Now it's too late.
