I don't think that's normal, seems like a number of issues that could stem from that.. mold due to moist air being vented right onto wood/drywall/plywood, outside air filling that area, etc.
"Why is this exact spot on the kitchen floor so cold every winter?!"
Why would they NOT vent it if it seems like it's possible/easy?? I've only ever seen something like that when venting outside would have been expensive.

Yeah, there is no mold or anything, but the bathroom is basically never used.
My theories are that it was originally just a toilet/sink bathroom and at some point a remodel happened and a shower added, but the floor drain kind of kills that idea.
However, this house has a crawlspace beneath the basement floor and then a concrete foundation, so maybe not out of the realm of possibility.
My other theory is it was just f'n lazy housebuilding.
