I have installed many bathroom and kitchen faucets in my time.  So installing this one was a breeze! My old faucet had the big plate underneath, to cover the holes since it was a single handle faucet, I was surprised when I pulled it up. There was rust and gunk underneath there, that I had no clue about.!  Yuck!  I have never changed out the drain on a faucet, so I ended up turning to the tune and watched how to do it, super simple. And taking my old elbow out and cleaning it, was a much needed chore.  The  Brushed nickel finish looks stylish, in my bathroom. Going from chrome to brush nickel really did update the look of the bathroom   Everything was included in the box and the instructions were simple to follow.
