Beautiful bathroom addition!
This Faucet and handle set from Delta is so sleek and beautiful. It will complement any bathroom. I love that the neck is so long and high up than most bathroom faucets. It really elevated my boring bathroom with its simple design. It also wipes down very easily to remove any smudges. It comes with everything you need besides the tools and could not be easier to install.

Hard to Keep Clean
This faucet gives a nice, sleek look. No surprises with installation. The only negative I have is that it shows fingerprints and water droplets on the handles. That goes with the sleekness and the indentations on the handles.

Sleek and modern!
This is a very nice faucet. Sleek and modern! It’s extremely well made, durable, and made of metal. Water flow is great without being excessive. I knocked off a star because it’s extremely prone to smudges, which I’m not a fan of. Otherwise, highly recommended!

Great bathroom sink faucet
Delta is a favorite brand of mine. They make products durable. Easy-to-install, from my husband's calculation. The color is lumicoat chrome,which doesn't leave fingerprint or water droplet. This is a wide spread faucet. It comes with a sink stopper that is easy to put in.

Doesn’t fit standard sink vanity
Such a beautiful product but unfortunately doesn’t fit a standard vanity. Called customer support and they said to make the handle hole larger to fit this product but it should have fit my standard vanity. Unfortunately the item doesn’t look complete and wi have to uninstall.

Amazing!
We really like the finish of this new sink handle and faucet as it is shiny, sleek, and modern! It was so easy to assemble for my Fiance, we wished we had done it sooner. The sink is so quiet now and even better, the coating makes it water stain proof!

Smooth and luxury
It looks so luxury by the high end design and polishes finish. The handle turns smoothly with good control over water temperature. I also like that it resists water spots pretty well. It is easy to install by myself. I love it!
