yes. the end stall has slightly larger as its for handicapped or people that want the seat in the shower. I had a regular gym buddy and after the jacuzzi he wonder down to the last shower stall, turn, and look in my direction. I'd follow in a minute or two.
I've started doing this more. At first I found it a bit weird joining another guys cube but if he's giving you eyes and the door is cracked, my new philosophy is might as well go try if you are in the mood. If they don't want it, they will close the door.
I think it you grab your cock or flash it and they don't get hard or start grabbing it, then maybe it's a different signal but I think 90% of the time if you are thinking they want it, they do, just everyone waiting for the moves to start.
It was a while ago, but yes, I have done this. The shower area traffic was pretty slow--the shower area had individual showers closed with a thick curtain (not see through). So when the way was "clear,"we jumped into a shower together. Very hot action......bodies coming together....belly to belly, hard dick to hard dick....lots of kissing, groping, mutual jerking and sucking..... ended with powerful orgasms.......
And yes.....knowing that occasionally there were other guys walking by or showering next to us---all without knowing that we were right there in the next shower jerking each other and sucking each others cock----was a huge turn on.....
