Rated 5 out of 5 by from I love this faucet This faucet is beautiful. It is so easy to use which is perfect for someone older. The pop drain gives a good seal for the basin but allows swift drainage of the basin when open. I’m very pleased with this faucet.

Rated 3 out of 5 by from Looks good, but leaking I really like the look of these faucets. We are living in a newly built house, moved in 10/2024. One of these faucets has already developed a leak from the handle. The leak developed overnight, seeped down the installation hole in the counter top and flooded the bottom of the vanity cabinet, also spilling onto the floor. We currently have the water shut off in that bathroom.

Rated 4 out of 5 by from Well Designed, but Stainless Finish shows Water Spots We remodeled two bathrooms and installed Lahara faucets in both of them. In one bathroom, we installed the Champagne Bronze finish, which is lovely. In the other bathroom, we installed the Stainless finish. I really love the function/feel of this faucet in every other way, but was surprised that the Stainless finish shows water spots. It's not a big deal to me. It's our kids bath, and functionality/durability is more important to me in that room than a spotless appearance (it will NEVER be spotless anyway :p). All of the plumbing fixtures in that bathroom are Delta stainless finishes and they ALL show water spots badly.

Rated 5 out of 5 by from Smart Design We had the Delta Lahara single hole faucet in Champagne Bronze installed in a powder room renovation. It is a beautiful faucet with very smoothly functioning features. Maybe it sounds weird, but the handle feels really nice in my hand...smooth to the touch, well designed, smooth action. We also installed the same faucet in stainless, in another bathroom. But the stainless finish tends to show water spots.

Will the Brilliance Stainless Finish Resist Damage from Straight Vinegar?

My wife uses CPAP equipment and the hose and mask have to periodically cleaned with straight vinegar. Will the vinegar damage the Brilliance Stainless finish on the faucet and especially the drain assembly? I'm talking 26 cleanings per year for the foreseeable future. Thank you!
Asked by: Rick
Hi Rick, Thank you for your question. We recommend to clean the faucet with half white vinegar and water. Straight white vinegar should not damage the finish if rinsed off soon after contact. However, repeated soaking with straight vinegar for more than a couple minutes could damage the finish. Best regards, Jon

I ordered a facuet set in the champagne gold. It appears that it is going to fingerprint easily. Have you had any complaints?

Asked by: Gloria
Thank you for your question, Gloria! Our Champagne Bronze is a Brilliance finish and is designed not to corrode, tarnish or discolor for a “like-new” look for life. While this does not prevent fingerprints from getting on the surface, these can be easily cleaned by wiping the finish with a damp cloth. If additional cleaning is needed, we recommend using a 50/50 solution of white vinegar and water. Best regards, Jon
