“Talk Now! Klingon” addressed the restroom issue:

   be' puchpa'                         ladies' toilet (TNK)

   loD puchpa'            gents' toilet (TNK)

loD be' ghap might be better, though nowadays joq and/or may be more politically correct!  <g> 

Using le'be' be unexceptional/nonspecific/general is another option.

I've been asked to supply Klingon text to label restrooms at a hotel. 

I presume {loD} and {be'} will suffice, but I figured I'd start a discussion as this list has enjoyed discussing restrooms in the past. 

They also need a label for a gender neutral restroom. 

People who use this restroom may object to {loD be' je}. I presume {Hoch} works for this?
