Is this about that throw-rug that looks like a toilet overflow? Or about the fact that the shower and toilet seem to be in the same place?

there’s no shower. the hose thing is for cleaning your ass, like a bidet, if that’s what you’re referring to

How can you guarantee that all that water ends up in the toilet? Plus there’s no drain in the room. And there’s a fucking shag rug that’ll get soaked with poo water

Same way that you usually guarantee that all the poop and pee ends up in the toilet

take a blacklight into this bathroom of yours
