One note about installing, though! The general concept is that you unscrew the water supply line at the toilet tank, lower it a couple inches, screw the Mini-Shower to the water supply line, and then screw the Mini-Shower to the toilet tank. This only works IF you have a flexible water supply line.
We had a rigid metal water supply line that wouldn't bend to make room for the Mini-Shower. I had to buy a whole new (flexible) water supply line and replace it when I installed the Mini-Shower. It wasn't a big deal. The new line was like $5 (and I only paid $17 for the Mini-Shower on the TP) and was easy to install. I did, however, have to have DH tighten everything when I was done b/c I'm too weak to tighten things tight enough to not get leaks. :LOL
