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.

Rated 1 out of 5 by from There are better options If you have children, I wouldn't suggest this. This faucet has the most sensitive shut off lever and is always dripping. You'll spend 5 minutes just trying to figure out the correct position for the lever so it stops dripping. Not worth it.

Q&A

My faucet when installed was working fine. 2 wks Now it barely flows. I took the aerator off and cleaned it, I checked the pressure, it's fine, no kinks in the hose. I ran a wire up the faucet, no obstruction. Could it be my cartridge is faulty?

Asked by: Kgriffis
Good afternoon Kgriffis! Thank you for contacting Delta Faucet Company. We are sorry that you are having a concern with your faucet and will be happy to help you. Reduced flow is typically caused by debris. If only one side is affected, there is debris in the supply line. To flush the supply line, first shut off the hot and cold water supply. Remove the hot supply line from the shut off valve and place the line into a bucket. Open the handle to the middle position, fully open, then turn the cold supply back on for one minute. The cold water should flow through the faucet and out the hot supply tube. Reconnect the supply line and turn on both supplies. Check flow from the faucet. If this does not help, please let us know. We appreciate your business and look forward to continuing to serve you! Please contact us back if you have any questions or need further assistance. Best Regards! Frank CSR Agent

We have this faucet in Venetian Bronze. The finish is pealing very badly and the faucet leaks when turned off. It was new in 2015 when the house was built. Is any of this under warranty?

Asked by: Konrad

I have a double vanity in my guest bathroom. One Lahara faucet works fine. The other works fine for hot water but has a very low flow for cold water. The valve under the sink appears to be completely open

Asked by: Sandy
Hi Sandy, Thank you for your question about the Delta Faucet model 538-MPU-DST. Please accept our sincere apology for the inconvenience you are experiencing. We are happy to help! The issue is likely caused by water debris trapped in the cold supply line or the faucet. Flushing should help fix the issue. Turn the supply off to both the hot and cold-water lines. Once off, turn the handle on the faucet to the on position and leave it there to bleed the lines of any excess water. Next, disconnect the cold water supply line and place it inside a bucket. Once the line is securely positioned into the bucket, turn on the hot-water supply. Since the handle was left in the on position, the water will flow up the hot supply line, through the faucet cartridge, and back down the cold water line into the bucket. Leave this flowing for at least 30 seconds. After flushing, reconnect the cold water line and this process can be repeated with the hot water line to ensure all particles have been removed from both supplies. Please contact us directly if you have any additional questions or need assistance! Best Regards, Bryan Digital Communications Specialist
