Motherfucker, you just shat out of your delicate asshole. Tap water ain’t gonna hurt it.
I think it’s more… What other people did with the bidet hardware that might result in it spraying other things with said tap water.
You do know that toilets are like, the easiest to clean piece of furniture ever invented. Like the thing is designed to withstand being sprayed with chlorine on the regular. It’s literally a porcelain basin that has a built in water flushing system. If it’s your home’s private toilet, no one else but you will ever use it and you can make it as clean as you want it to before using it.
Even then, epidemiologically, in any given public bathroom, you’re several orders of magnitude more likely to catch an illness from the door handle than the toilet.
See “the cons”. I’m lightly convinced for private residences… Public restrooms as awful as I’ve seen them, I don’t know about.
