This is a beautiful faucet and really transforms the sink and room.  The instructions are very clear.  The sink drain does not fit securely into our sink so we needed to add some clear caulking to insure no leaks. We are not plumbers and we’re able to set it up!  Be sure you position the hot and cold tap handles correctly so you have the correct range and direction you want to turn. (This took a bit of trial and error for a DIYer). The inner fixtures hang low so fitting the p trap took a bit of work as well.
