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.

Q&A

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

Lahara model single handl sink faucet does not get lukewarm. I have limit stop set to prevent scalding but I would like it to get safely lukewarm.

Asked by: George
Hello George, Thank you for contacting us, I would be happy to help you. Our Delta Faucet product including 538-CZMPU-DST does not have a temperature adjustment, we recommend to make sure the water heater is set to 120 or lower and also to flush the faucet. To flush the unit, we recommend the following: 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 hot water supply line and place it inside of a bucket. Once the line is securely positioned into the bucket, turn on the cold-water supply. Lastly, you will follow these same steps for the cold supply line. Please contact us back if you have any questions or need further assistance. Best Regards, Nicole
