I put one of these in my guest bathroom, and now there is no way I would ever want to be without one. I put them into much the same category as a microwave oven, TV remote control, or a backup camera on a vehicle.
Once you have one, you'll wonder how the hell you ever lived without it. I'm sorry, but this is where the Europeans have us beat all to hell. They discovered long ago it is much better to have a system to wash your backside. Where as we still think taking dry paper and smearing crap all over it is, "clean enough".
You wouldn't wipe your sweaty armpits with toilet paper and call them clean. So why would you do the same with your butt? Sorry to be a bit crude, but there is no better way I can explain it.
This unit from Home Depot is well made, not expensive, easy to install, and works like magic. And if someone asks "what is that"? Just tell them, "You don't see any grass or plants in here, do you"?... Trust me, they'll be able to figure it out.
