Can it be gross? Of course. Shit is shit, and shit is pretty gross. But it's the shit room. The shit room for shits. If you have one shit room and someone you care about desperately needs to shit while you are bathing or showering in the shit room, you either get out of the shit room so they can shit, or they enter the shit room for shits.
