The drain should be within the shower area, with all the bathroom floor draining that way.

If it's in the centre of the room it's been done very badly. I've never seen this in Denmark, even in some very old apartment buildings.

I’ve lived in a newish apartment where the wet room drain was in the center. It didn’t seem weird at all. There wasn’t much separation between the shower and toilet and sink, though.
