Back at my old job (I haven’t really worked in an office since, remote and all that) the newer building across the street had restrooms with stalls that closed all the way and went down to the floor, no gaps. And there were an absolute ton of stalls. (One of the issues I’ve had since gender transition is the continued need to use a stall but there are usually way less in the men’s room, but the restrooms in that building had so many stalls, it was incredible.)
