The Delta - 15840LF-SP faucet is quick & easy to install. I did a reno in my bathroom and we wanted a bathroom faucet  with a single hole design/single handle. The simple design on this was nice. Our vanity,  the vanity top had 3 holes, but this Delta faucet came with the  plate that installs with the faucet to cover the holes.  I was able to install the faucet,  and still have the look of the single handle faucet.  Looks great in the brushed nickel finish.
