What a cool addition to our shower!  The better your water pressure - the better the performance of this system.  It was a couple of weeks between delivery and installation - it looked so good, I showed it to friends just lying there in the box.  The Panel system works great - easy to install - more or less - I bought longer supply lines and fed them back through the single handle faucet hole & made the connections behind a vanity.  Think it through before you buy - I like it a lot!
