This is what I’m referring to. They’re little hand held shower-like attachments that are fitted next to the toilet. After you’re done with your business, you lean forward, use the attachment to direct a jet of water at your nethers, and then wipe dry with toilet paper(which comes away nice and clean on the first go). They’re quite common in much of SE Asia, India, and possibly other parts of the world that I haven’t visited.
Every American I’ve met who has used one(and with whom the subject has come up) is a convert. I know there are a few posters here who have used it in their travels and have gotten them installed at home. How is it that this is a product that isn’t more widely installed?
