Biggest Plot Hole in Series

Colony House has 1 bathroom for 17 people or whatever it is. S3 E1 Famita is throwing up in the bathroom and a girl is banging on the door for her to hurry up. Then when Famita is done, the other gal says she almost peed on the floor. How the heck does Colony House have one bathroom? I guess the guys can piss outside to relieve some congestion, but that's not right. Image the morning line to take a shit.
