Touch it on. Touch it off. Or go completely hands-free. Delta® Touch2O.xt® Technology helps keep your bathroom clean by giving you three ways to operate your faucet: manually with the handle, with a simple touch anywhere on the spout or handle, or by placing your hands near the faucet. The high-tech capacitance sensing capabilities of Touch2O.xt faucets allow the flow of water to be activated by breaking the capacitance field anywhere around the device, unlike traditional hands-free infrared sensors which require your hands be in a particular place and are sensitive to lighting conditions and clothing and skin color. Touch it on. Touch it off. Whether you have two full hands or 10 messy fingers, Delta® Touch2O® Technology helps keep your faucet clean, even when your hands aren’t. A simple touch anywhere on the spout or handle with your wrist or forearm activates the flow of water at the temperature where your handle is set. The Delta TempSense™ LED light changes color to alert you to the water’s temperature and eliminate any possible surprises or discomfort. Delta® faucets with DIAMOND™ Seal Technology perform like new for life with a patented design which reduces leak points, is less hassle to install and lasts twice as long as the industry standard*. You can install with confidence, knowing that Delta faucets are backed by our Lifetime Limited Warranty. Delta WaterSense labeled faucets, showers and toilets use at least 20% less water than the industry standard—saving you money without compromising performance. *Industry standard is based on ASME A112.18.1 of 500,000 cycles.

Rated 1 out of 5 by from Finish is deteriorating and pitting While I am quite happy with the function of the faucet, its exterior finish is pitting like a facial blemish. This is only 4 months after installation. A deciding factor in purchasing the Delta product, besides its technology, was its durability experienced with our kitchen faucet installed four years ago. Now I have go to trouble of contacting the company and paying again for the installation of a replacement

Rated 1 out of 5 by from This Faucet is Terrible This faucet is terrible. The touch and motion sensors go off randomly and cannot be adjusted! I bought this faucet because we just installed a similar Moen faucet in the kitchen which works flawlessly. Unfortunately Moen doesn't make a bathroom faucet with motion sensors.

Rated 5 out of 5 by from Lahara Single Handle Touch2Oxt Bathroom Faucet Typical high quality Delta fixture. It was my first Touch installation. No issues at all with install. However, the fixture has cost me extra money. Two days after install, bride declares Kitchen fixtures must now be Touch activated. Sigh.

Rated 1 out of 5 by from touch faucet design problem First the LED light for the sensor does not work. Delta is sending a replacement but I have to disassemble and install (again). Worse the design of the solenoid valve location interferes with the drain rod - rubs the plastic pipes and valve box. I cannot installed this rod (to the sink drain) because of the potential for a leak. You cannot move the box to either side without putting it in a bind. A touch drain for the sink doesn't work due to the tail piece is metal and interferes with the sensors. I you can live without a sink drain, you can use this faulty product. Also, Delta reps kept saying no manuf defect.---Right!

Rated 5 out of 5 by from Very nice product. We purchased this faucet as a replacement. The no touch technology is awesome and is really great for the grandkids since they do not need to touch anything when they wash their hands. They can simply waive their hand under the faucet -- it automatically turns off when they are drying their hands. It was a little tricky at first to get the hang of it but now it is second nature.

Rated 5 out of 5 by from Touch / motion works great Great looking. Touch turns on / off for about 60 seconds. Motion sensor turns on for about 5 seconds. Both work great. Kohler includes everything needed to hook up in box.

Rated 3 out of 5 by from Fanastic faucet when it works. I love this faucet when it works, but it has stopped working twice in the year that I've had it because of defective solenoids. Delta customer service has been excellent in supplying the necessary repair parts in speedy fashion, but it is frustrating to be without a bathroom faucet for a week or two every six months.

Rated 4 out of 5 by from Fun to use! This facet is fun to use and conserves water. The elongated spout makes bending over the sink a thing of the past. The facet was installed easily by a professional handyman. Easy to keep clean.

manual function

Can this faucet turn on manually. I am considering purchasing it for my mom's bathroom. She has Alzheimer's and I want to make sure she does not leave the faucet running all day.
Asked by: Delta fan
Hi Delta Fan, Thank you for your question. You can place the model 538T-RB-DST in manual mode by turning the faucet on and with the water running disconnect the battery pack. If the faucet is left on in the Touch mode it will only run for 1 minute with no activity before shutting itself off. Thanks, Dave

Does the Lahara bath faucet have a baseplate for an 8" 3-hole spread?

Asked by: Bill
Hi, Bill! Thank you for your question. The only escutcheon plate available for the Delta 538T-DST faucet is the RP51346 which is 6 1/2" (165 mm). There is not an 8" option available. Best Regards, Rosanna

Is there a way to adjust the motion sensitivity of this faucet?

I would like to extend the motion sensitivity of the faucet by a couple of inches. The water shuts off when people are soaping their hands and then takes a couple more waves of the hand (sometimes more) to get it flowing again. If the proximity can't be adjusted, can the motion sense be shut off completely so it becomes a touch faucet? thanks!
Asked by: Sean
question re: Delta1's answer... "is equipped with touch free and a hands free mode" What is the difference between Touch free and Hands free mode? Did you mean to say that the 2 modes are - touch - hands free (via proximity)

Why is supplied pop up needed?

I'd rather not pull apart the plumbing under my sink. The installation manual says that the supplied pop up is required for proper function. Why?
Asked by: SK
Hi SK, Thank you for your question! The pop up assembly supplied with the faucet is manufactured to work with the touch faucet. Other pop ups may interfere with the touch technology. Best regards, Brandis

Re-activate Sensor on 538T-SS-DST

How do you re-activate the sensor on the 538T-SS-DST? It appears the sensor was accidentally de-activated, however, I cannot find re-activating instructions. I tried the same de-activating instructions to 'undo' the procedure and the light flashes blue and red but the sensor still does not work. Removed and re-installed the batteries and it does not re-activate the sensor. The batteries are fully functional as displayed by the strong blue light. The faucet works fine when it is physically touched to start and stop the water flow. I have two of these faucets that were professionally installed at the same time and the other faucet is working ok.
Asked by: LoveDeltaFaucets
Hi Dave, You may delete the "Re-activate Sensor on 538T-SS-DST" question in its entirety. After several attempts, I was able to re-activate the sensor feature using the same de-activating procedures. I do however recommend the "Quick Tips" instructions which state the procedures for the sensor that came with the faucet be added to your website. I finally found my hard copy of these "Quick Tips" but would have been helpful if the website had them available. Thanks.

Please explain the differences between Lahara faucet 15938t and 538t?

Asked by: Richard
Hi, Richard! Thank you for your question. The 538T-DST faucet is a Touch Proximity faucet that you're able to 'wave' your hand at the faucet to turn on and off the faucet. You can also touch the faucet to turn on as well! The 15938T-DST is a Touch faucet only. It does not have the Touch Proximity where you can 'wave' your hand at the faucet to turn on and off. Best Regards, Rosanna

If this faucet it turned on manually and left on, will it turn off automatically, or just remain on indefinitally?

Asked by: SSgtGuy
Hi SSgtGuy, Thank you for your question! With the Touch2O feature on, the faucet will need to be activated by touch or proximity, and will automatically shut off after 2 minutes. In manual mode (power supply removed) the faucet will not automatically shut off. Best regards, Jon
