Rated 4.3 out of 5 by 8 reviewers.
Rated 5 out of 5 by Like the design but champagne color doesn't match other Dryden products. We really like this faucet including the shape and water flow but the champagne color doesn't match the other products in the dryden line including the roman tub faucet and shower faucet. October 31, 2012
Rated 5 out of 5 by Great looking faucet We bought 3 of these faucets to go with our new Kohler Archer sinks. They look great together. Love how easy the faucets turn on and off. Would recommend them to everyone. June 30, 2013
Rated 2 out of 5 by Plumbing line collapsed on two faucets Our professional plumber installed two of these faucets and both had the lines collapsed. Can Delta respond if this is a systemic issue? Or possibly due to a common an installation error? December 10, 2013
Rated 5 out of 5 by Classic! I chose this faucet for my remodeled bathroom because I wanted only one hole in the countertop, I wanted a far enough "reach" into the sink bowl to keep excess water off of the counter top, and my swanstone top has a rectangular bowl shape and this square looks nice with it. I think one hole makes for easier cleanup. The faucet is very sturdy feeling and I am glad I chose it. December 13, 2014
Rated 3 out of 5 by The Pop Up drain does not close tightly, thus leaks! We bought both this tap and it's similar touch model for 2 bathroom renovations in the colour oil rubbed bronze. The touch model works great and has a pop up drain that is different than this model and it seals great! This model's pop up drain does not seal properly and it leaks water slowly through it. Both of these taps were installed by a plumber and he said that this one has a poor design! To note, we had the same 2 Kohler Archer under mount sinks installed in both bathrooms, thus this is not a sink issue, but rather this tap's poor design on the pop up drain! We love the design of this tap, but with this current pop up drain problem, we are not happy with the leaky pop up drain! This is unfortunate since we spent time researching and spent a lot of money on these taps! September 1, 2015
Rated 4 out of 5 by I really like the faucet. The design of the drain lever makes it very difficult, if not impossible, to raise or lower, for this reason I would not recommend it. It's a beautiful faucet and, like all Deltas, it works great. But this pop up drain issue is a big deal. May 29, 2013
Rated 5 out of 5 by Well Made Faucet This item was part of a complete update of my master bath. Very happy with the style and performance. Easy to keep clean. Another plus is the fact that it is metal - not plastic. March 5, 2015
Rated 5 out of 5 by Money well spent Works great, looks stylish, price was right for bathroom remodel December 10, 2013
