My friend has one of those Japanese ones. It also has a warmed toilet seat. When I came out, I said that seat is amazing and they said people never come out of there. I proposed that they were napping on the seat. Why do seat warmers feel so good? The thing is, I could never figure out how to make the actual bidet part work. I suspect the people who took a long time were also trying to test it out, but didn’t know how. Or maybe they did and enjoyed it?

It’s as easy as using two shells.
