Riker’s toilet would be placed right in the middle of a room … so that he could walk up to it, swing his leg over and sit down
The Riker Maneuver
Do it somewhere on the holodeck.
I can’t find the exact timestamp but Jonathan Frakes does point out the single bathroom on the Enterprise D in the 1994 documentary “Journey’s End: The Saga of Star Trek — The Next Generation.”
But why would you use it when you can just use the holodeck? (crude humor warning)
Can’t you just go onto the transporter?
pretty sure you can, would be strange if transporters can’t handle gases…
The smell won’t stay on the transport pad, you’d have to transport the whole room.
And here’s me about two hours away from my copy of the Star Trek: The Next Generation Technical Manual to debunk this obvious joke with a picture of all the architectural diagrams where it calls out places where one might find a head, including, IIRC, the Ready Room, of which I imagine Riker probably avails himself on the regular.
Why yes, I am fun at parties…
