I’m Italian and I must support @FaceDeer 's point, these are standard in my country (and they should be standard everywhere, damn barbarians) and they are definitely better than a spray nozzle attached to a toilet. You can also use them for other things, like washing your feet.
So you have a dirty crack, you got to get up, and waddle through the bathroom with pants on your ankles?
Yeah, I’m wondering about that. I’m a filthy TP barbarian but, how exactly does one make this style of bidet work?
