Rated 3 out of 5 by from Loved it, for 2 years This faucet was wonderful for 2 yrs, until the calcium in the hard water ruined it. Delta only warranties the faucet, not the labor, so it cost me over $1K to replace it. It's so complicated most plumbers don't know how to install it, and the instructions are terrible. Had to pay for 3 plumber visits, and be without a shower for 2 weeks, and the temperature part is still not fully functional. I'll buy a cheaper faucet next time.

Rated 4 out of 5 by from Poor Set Screw Placement I just installed two of these (T17T238 and T17T438). My only complaint is that the set screw on the water volume control handle is positioned on the top (12 o’clock) when the valve is closed. The installation kit included a small (tiny) button to cover the opening. Because of its position, it invites little ones to pick at it — whoops, down the drain. It’s difficult to find replacement buttons because they are not shown on the faucet’s parts diagram. A better design would be to move the set screw hole from the left side of the knob to the right side such that it’s positioned on the bottom of the handle when installed. Other than that, the faucets work great.

Rated 1 out of 5 by from Poorly designed We installed two of these in a shower and the temperature knob rubs metal to metal and is not smooth. We ordered the same style delta with out the temp assure and it went in perfectly.

Rated 5 out of 5 by from Delta 17T Mixing Valve [This review was collected as part of a promotion.] Works great. Better water volume makes for a better shower.

Rated 2 out of 5 by from Falls apart The screw under the temperature control keeps coming loose. I have had to replace numerous parts on 3 different occasions. Thankful for the lifetime warranty. Nice looking, functions are fine, but poor design.

Rated 5 out of 5 by from Great concept, but... UPDATE This is an update to my previous review. Customer service saw my review & contacted me shortly after the review went live. They concluded that the valve was defective & promptly sent me a new one. After install, all issues were resolved & the unit is functioning as it was designed. I regained full temp control and full pressure (feels like even more than the first one ever did). Thank you Delta Faucet.

Rated 1 out of 5 by from Great concept, but... I bought this last year as we planned to renovate our bathroom. We finally installed this late in the year as the valve trim is one of the last pieces to go on. For the first few months,(winter time) the valve worked great. Always the same temp, but the pressure would be a little lower on the second shower of the morning. It kept getting worse. Then after a few months, the pressure was a trickle, barely enough to rinse shampoo out of my short balding hair. Now I get 2 options, either pure cold @ full blast or hot @ a trickle. Since I have full blast cold, their is obviously nothing clogged in the showerhead, so that's not the issue. This unit is fed after the hall bathroom sink, but before the master sink, & both of those faucets work perfectly fine with both temp & pressure, so that's not it. This is shower only, no tub so there's nothing else in the way except this faucet. So I started reading the bad reviews for the unit, there are a lot of the same issues, people complaining of low or no pressure. A few said that the temp controlling cartridge gets stuck, so I took the palm of my hand & gave it a whack. Now I get more pressure, but if I turn on shower at a temp & leave it for a few seconds, now o can no longer change the temp of the water. It's stuck at that temp. If I turn off water & wait a couple minutes, still no change in water temp no matter where you set control lever. Why is this even possible, I get either cold full pressure or hot trickle or better pressure but at whatever temp it feels like giving me. There are a not of good reviews, but pay better attention to all the bad reviews also before you purchase. I'm now stuck with a useless shower unless it's super hot outside or if I don't actually want to rinse off. Oh yeah, I can also play roulette & gamble on getting frozen or scalded.

Q&A

One handle or two?

I am trying to choose between this and Trinsic. The picture shows two handles but the product search says one. Which is is it?
Asked by: tomluoma
Hi, tomluoma! Thank you for your question. The faucet, T17T038, has one volume handle that turns the water on and off and a second knob control that changes the temperature when turned. Best Regards, Rosanna

One of my T17T438 (Lahara) temperature control handles has a lot of play and seems loose. It appears to need tightening but I don't see a way to do that. I have two of these controls in separate bathrooms and only one has this problem. Is there a fix?

Asked by: jmd55
Hi, jmd55! Thank you for your question. I am sorry to hear that you are experiencing an issue with your Delta faucet. To tighten the temperature knob control, simply pull the temperature cover straight off. Tighten the screw with a Philip's screw driver. Best Regards, Rosanna

We just remodeled 2 bathrooms and installed all Delta faucets. I was always pleased with Delta's reliability and reputation, but I am very disapointed in the quality of Lahara TempAssure 17T. It is covered in water spots. Why? We used no cleaners!

Asked by: judie
Hello Judie, Thank you for your inquiry! Here are the cleaning care procedures for the Delta Lahara Thermostatic Valve Trim T17T038 model and our other Delta faucets. Always blot dry any water from the faucet surface. Allowing water to evaporate on the surface can lead to build up of mineral deposits. Cleaning with a damp non-abrasive sponge and buffing it dry with a clean soft cloth should help keep your product looking beautiful. To remove water spots, use warm water and a soft, damp cloth. Hard water stains may be removed using a 50/50 solution of white vinegar and water. Make certain that you rinse the surface thoroughly with water afterward. If additional cleaning is required, all of our finishes may be cleaned with the following household cleaners: Formula 409® Antibacterial All Purpose Cleaner, Fantastik® All Purpose Cleaner, or Windex® Original Glass Cleaner, when used according to the manufacturers' instructions for use. Avoid using the following which can damage your finish: Avoid industrial cleaners and abrasive cleaners, such as those used for toilet bowls, green Scotch-Brite heavy duty scrub sponges, Scrubbing Bubbles Bathroom Cleaner and Lysol Basin Tub, Soft Scrub, and Tile Cleaner. Avoid products that state on the label that they remove tarnish and rust and those containing hydrofluoric, hydrochloric and/or phosphoric acids and caustic agents. Avoid harsh abrasives or polishes. Avoid bleach-based cleaners. Best regards, Tanya

depth of valve trim

What is the depth of this valve trim from back of cover plate to end of valve? You don't document that. Looks like it sticks out further in the room than pressure type valves.
Asked by: JimS
Hi JimS, Thank you for your question. The end of the trim projects approximately 4" from the wall, but may vary up to 1/4" depending on the installation depth of the rough-in. Best regards, Jon

Do the TempAssure valves control the temperature over the entire range of volume (trickle to full flow)?

Asked by: BrianJ
BrianJ, Thank you for your question! Our TempAssure thermostatic models allow you to control the volume and temperature independently. The temperature can be adjusted at any volume setting. Best regards, Jon

If I plan on using the In2ition w/H2Okinetic shower head only (no tub faucet), do I need the rough in to switch from head to hand held?

Asked by: Kim
Hi, Kim! Thank you for your question. You will not need a diverter rough for any of our In2ition w/H2Okinetic shower head as they have a built-in diverter in the back of each shower head to change from shower head to hand shower to both on at the same time. Best Regards, Rosanna

If I want to use this trim with just a tub spout to fill a soaker tub would I get more flow with a High Flow Rough-in (piping the top port to the tub spout) or with the standard 10000UNBX (using the bottom port for the tub spout, capping the top port)

Asked by: Jim21
Hello Jim21, Thank you for contacting Delta Faucet Company! I am sorry this information was not readily available, and I am happy to help you! Our Delta Faucet Lahara® TempAssure® 17T Series Valve Only Trim In Chrome MODEL#: T17T038 would work best for your specific setup using the R10000-UNBX and capping off the top port. The top port has a flow restrictor and the bottom port does not, by plumbing the tub spout off the bottom port, allows for the full 8-10 GPM. Thank you for being a loyal Delta Faucet customer. We appreciate your business and look forward to continuing to serve you. Please contact us back with any further questions. Best Regards, Nicole

I have a Lahara shower faucet model T17038 that has started to leak how do I receive warranty parts it was installed in January of 2015 in a bathroom remodel 

Asked by: Carl
Hi Carl, Thanks so much for contacting Delta Faucet Company! It is possible that flushing the LAHARA® TempAssure® 17T Series Valve Only Trim MODEL#: T17T038 could resolve this issue. To do this, turn off the water supplies, remove the cartridge, and turn the supplies back on for one minute. Please make sure that you are getting good flow through both the hot and cold sides while flushing. You can also shake the cartridge back and forth to make sure the back half of the cartridge rattles. This means that the pressure-balancing spool is moving freely, as it should. If you would like installation help, you may contact our residential warranty line directly at 800-345-3358 (prompt 2, then 4). We are available Monday through Friday from 8 a.m. to 8 p.m. and Saturdays from 9 a.m. to 6 p.m. Eastern Standard Time. We also have how-to videos on our website and on our YouTube channel. https://www.deltafaucet.com/service-parts/how-to-videos Please reach out with further questions!

I have the T17T TempAssure shower/bath valve. When running bath water it causes the hot water pipe to vibrate clear back to the hot water tank. Is this normal operation? This will eventually cause the hot water pipe to break!
