Product Overview

Convenience just got more convenient with this Dryden Single Hole 1-Handle Bathroom Faucet in Stainless with Touch2O.xt Technology. TempSense Technology measures the water temperature in the faucet. The LED light at the base of the faucet changes from blue to magenta to red depending upon the temperature of the water to let you know when the water temperature is right for you. A/C adapter EP73954 is available to purchase separately as an option to avoid changing batteries. Even if the adapter is used, batteries are still recommended as a back-up if power goes out. Once power is restored, the solenoid valve will automatically revert back to using A/C power. With Touch2O Technology, it doesn't matter if you have two full hands or ten messy fingers. Tap anywhere on the spout or handle of the faucet with your hand, wrist, or forearm to start and stop the flow of water. Delta's exclusive DIAMOND Seal Technology uses a valve with a tough diamond coating. InnoFlex PEX waterways keep water inside the faucet out of contact with potential metal contaminants. Delta is committed to supporting water conservation around the globe and has been recognized as WaterSense Manufacturer Partner of the Year in 2011, 2013, and 2014.

Customer Questions & Answers

Pedestal Sink

I would love to install this faucet in my half bath. My only concern is that this would need to be installed in a pedestal sink. The faucet and water lines should not be an issue but the battery pack would have to stand up vertically to be hidden. Also I would hope that the solenoid assembly isn't large and obvious to see. Has anyone installed this on a pedestal sink? Does Delta recommend against it?
Asked by: astonman
Hi Astonman, Thank you for your question. Delta Faucet model # 551T-SS-DST can be installed on a pedestal sink. We offer decorative covers for the supply lines. We have two styles-one is copper which is model RP72130SS and one is vinyl which is model RP72131SS. The battery pack can stand up to be hidden. Thanks. Jody

I looked at this Dryden Faucet for months before finally making the purchase. My hesitation was that I planned to install it on a pedestal sink in our half bathroom. I wasn’t sure if everything would fit in the confined space of the pedestal. Despite having considerably more parts than a regular faucet, the installation was rather easy. I did however run into two issues. The first issue is minor in my opinion. I had to use the included escutcheon plate since my sink has three holes. The plate has a type of foam padding on the bottom. I had to trim the foam otherwise there would have been a substantial gap between the plate and the sink. Even after trimming the foam there is still a slight gap but again this is just a minor issue. The second issue is more design related. The last part of the install is the pop-up assembly. This faucet is very stylish but that style affects function. The lift rod for the pop-up is hard to reach, but the real issue is that the lift rod and lever for the pop-up are all in the same area as the solenoid assembly. I’m not saying it wouldn’t have worked but it felt like a bad design. My solution for all this was to ditch the pop-up assembly that came with the faucet and replace it with a push pop-up drain. I purchased a matching Delta push pop-up drain. This of course was an added expense. Personally I think this type of faucet (with touch function) should come with a push pop-up drain. As far as function, this faucet has worked perfectly. The sensing field is just right. You can stand in front of the mirror, even lean in towards it but the water only comes on when your hands are within a couple of inches of the spout. Being that this faucet is in a half bath, it’s mainly used for quick hand washing. The water runs just long enough to do the job. When you need the water to run longer you just touch the faucet. The touch has worked flawlessly thus far. There have been no phantom on/offs. Just to mention, this worked out well on our pedestal sink. The battery pack rest on the floor but hidden within the pedestal. You can see the water lines but only if you purposely kneel down and look behind the sink. In spite of the issues I mention, we are very happy with this faucet. I purchased the matching toilet lever and towel ring to complete the look and love it all.

Rated 4 out of 5 by from Liked it however... This is a beautiful faucet. The touch aspect of the faucet still works however, the motion sensor stopped working about 2mths into using it and we did have the problem of it turning on and off by itself when it did work.
