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.
  • Operate hands-free by placing your hands near the faucet, with just a touch anywhere on the spout or handle, or manually using the handle
  • Helps keep your faucet cleaner, because washing the mess off your hands shouldn't involve making a mess of your faucet

  • Battery operated 6 AA (included) with a battery life of approximately 1 year or 6 C (not included) with a battery life of approximately 3 years
  • Optional A/C adapter EP73954 may be ordered separately

  • Helps keep your faucet cleaner, because washing the mess off your hands shouldn’t involve making a mess of your faucet

Rated 4 out of 5 by from Beautiful, functioned well for seven years Double sinks, same faucet. One has lasted for seven years in good shape, the other has gone kaplut. Maybe seven years is a good return. It is a beautiful faucet!! I personally think it is a waste to have touch, motion, and timed functions. Just get the regular one, beautiful, functional, and less to go wrong.

Rated 5 out of 5 by from Faucet thru Build.com Faucet was competitively priced and delivered as promised. Installation was fairly standard and the faucet works as advertised.

Rated 4 out of 5 by from Great features I bought this faucet a couple of months ago. The installation was fairly straight forward. The only problem I had was that the faucet would randomly turn on/off for about 5 seconds several times per day. I contacted Delta and after sending several pictures of the installation and several back and forth emails, they sent me a new solenoid. I installed the new solenoid and the faucet so far has been working as it should.

Rated 5 out of 5 by from CLASSY FAUCET I just completed a powder room remodel and used this faucet on a granite counter top with white undermount oval sink. It looks great. I love the finish using the Champagne Gold and was able to match it close enough with a new light fixture. It is so easy to use with the touch control sensor control. I have had no problems with any of the features. I highly recommend.

Rated 1 out of 5 by from Awful finish!! We bought two of these faucets for our master bath and the matching faucet set for our Roman tub. We had the touch technology in our kitchen and it worked so well. The bathroom faucet that is used the most started to corrode within 6 months. I contacted Delta and they sent a replacement one. Six months later and we had the same problem. This time Delta offered one at half price. The other faucet was also corroding. I ordered the half price one and have waited until I can't stand the corrosion to replace it. The touch tech has worked well but the blue/red light stopped working on both faucets. I think the single lever is part of the problem. Not sure what to do next.

Rated 4 out of 5 by from NICE LOOKING FAUCET I LIKE THE LOOK OF THE FAUCET. IT IS WELL CONSTRUCTED OUT OF STURDY MATERIALS. THE FINISH WIPES DOWN EASILY. I THINK THE ONLY ISSUE THAT I HAVE IS WITH THE MOTION FEATURE TO WORK THE LEVER NEEDS TO BE UP. AND MOST PEOPLE JUST NATURALLY PLACE IT IN THE DOWN POSITION. I ORIGINALLY HAD THE VERSION WITH JUST THE TOUCH ON/OFF FEATURE (WHEN I THOUGHT I HAD ORDER THIS VERSION) AND AFTER TRADING OUT FOR THIS VERSION I THINK FOR THE PRICE DIFFERENCE I WOULD JUST HAVE STAYED WITH THE ONE WITHOUT THE MOTION FEATURE. THE TOUCH FEATURE ALSO REQUIRES THE LEVER TO BE IN THE UP POSITION. I THINK REALLY FOR THIS TO FULLY EFFECTIVE I WOULD HAVE LEFT THE LEVER OFF COMPLETELY. THAT WAY WHEN THE PERSON APPROACHES THE FAUCET EITHER THE MOTION OR TOUCH FEATURE WOULD TURN ON THE FAUCET.

Rated 2 out of 5 by from Still undecided Great features of both "touch and sensing" technology for turning on and off. My faucet has been installed for about 1 1/2 now and I'm beginning to experience some electronic issues with the "on/off" solenoids. The first issue is solenoid does not turn off when water temperature is running hot, by sense or touch. When I move the level over to cold for 10-15 seconds, the solenoid begins functioning again. Solenoid doesn't like hot. Second issue now is water mysteriously turns on and off. Blue light is flashing in series of two flashes. Next step will be a test of customer service. Will update later....

Rated 4 out of 5 by from problems with solonoid on 2 faucets Bought 2 of the Touch 20XT bath faucets and installed them. Instalation was very easy. One faucet the soloniod was bad and it dripped all the time. The 2nd faucet had problems with the sense function and would not turn on when placing hands under. Talked to customer support and they were great and sent me 2 new solinods. I installed them and the leak was fixed on the one, and the sense was fixed on the other. After about 2 weeks the sense stopped working again. I called Delta support and they had me check everything and decided the faucet had to be replaced. I'm waiting for the new replacement faucet. I like the faucet, it had the latest features. It was very easy to install. I worry about the reliability since I've had some problems. I've used Delta for a long time and they back up thier products, so I know they will take care of me.

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
