Au contraire! I’d say there’s nothing good to be said about rubbing your hand down there, even with some toilet paper in it. Compared to using water toilet paper is downright dirty.
I have this unit as well as the fancy Toto Japanese toilet that warms the water first, and I expected to hate this, but hey for $22 it was worth a shot. Its installed in a cold environment, and even then I don’t particularly mind the cold water. Hell, its refreshing. Granted I prefer the warm water of my Toto, but it’s about 30 times the price at $650.
Conclusion: get a fancy Japanese toilet if you can, you won’t regret it. If you don’t want to drop that kind of $$ or just want to test the waters first (heh), get this one.
Fair warning though, the water pressure on it is off the charts strong, so be careful when you turn that dial up. I like to tell people to fire a “warning shot” first and increase the pressure slowly.
