Rated 1 out of 5 by from Dissapointed! Love the color, but only purchase if you don’t mind water spots. Installed this in my newly remolded bathroom and am beyond frustrated with cleaning it daily to look decent. We installed the Delta tetra model in the other bathrooms and they do not have this issue.

Rated 2 out of 5 by from Made cheaply despite not-cheap price Very plastic and the pieces don't all fit together right. The temperature knob wiggles back and forth! Also the two knobs do not move independently; I have to hold one to move the other one. I spent way more money on this set than it's worth.

Is this metal or non-metal?

Are the tub spout, lever, backplate and shower head made of metal or plastic (non-metal)? Thank you!
Asked by: mango19
Hi, Mango19! Thank you for your question. The T17438 unit escutcheon plate and handle are metal. The diverter tub spout assembly is non-metal. Best Regards, Rosanna

Can I use this kit for a shower only? If so will I need to buy a stopper to disable the tub spout?

Hi, Craig! Thank you for your question. The Delta Monitor T17438 Tub and Shower Trim Kit can be used as a shower only unit. However, we do have the shower only trim kit, Delta Monitor T17238 Shower Trim Kit. Here is a link to this: https://www.deltafaucet.com/bathroom/product/T17238 Best Regards, Rosanna

what is a rough valve?

Asked by: mark
Mark, thank you for your question! We often say that the rough-in valve is the part of the shower unit that you do not see as it is behind the wall. The trim is all the pieces that are visible to the eye. Our most popular rough-in valve is Delta Faucet model #R10000-UNBX. Information surrounding it can be found by following this link: http://www.deltafaucet.com/bath/details/r10000-unbx.html

I bought Tub and Shower system with separate hand held shower--parts T17438, T11800,57014, 50560, R100000-UNWS, and R11000. It appears that the only way to make it work is to lift the tub diverter each time. True? Alternative suggestion?

Asked by: mjbphx
Hello, mjbphx. Thank you for your question! Water will flow to the tub spout first and can then be diverted to the shower head or hand shower. This is the recommended installation for a tub and shower setup. The T11900 6-Setting Diverter Trim Kit will allow you to use the third port of the R11000 Diverter Valve. You may connect a non-diverter tub spout to the R11000, but the flow rate will be reduced by about 1 GPM when compared to the bottom port of the R10000 valve. Best regards, Jon

I have T13220 Monitor 13 Series Shower Trim (fits Multichoice Universal Valve). Brand new build, but I would like to replace with T17438-CZ series. Will this work with the existing rough valve? Documentation just shows R1000-UNBX or R1000-LBX.

Asked by: coz123
Hello coz123, Thank you for your question. A Multi-choice Universal rough-in valve like the R10000-UNBX/LBX allows you the choice of easily swapping out any of our current shower trim kits. Any current T13/14, T17 or T17T trim will work with this type of rough-in valve. Best regards, Edward

We have the R1000-UNBX universal mount with this faucet. Why are we getting water out of the shower piece when we turn on the hot? We don't have

the shower activated but we are getting water out of the shower valve. The hot water is not hot. It is hot coming out of other faucets.
Asked by: Angie
Hi Angie, We are sorry that you are experiencing a problem with your faucet. Most likely, you are experiencing "shower-rise" where the water can’t get out of the spout as fast as it flows through the valve. This causes the water to back up and come out the shower head. There can be one of several reasons for this: The valve could be upside down The length from the valve to the tub spout is outside of the 8" to 18" rule There is more than one 90-degree angle Something other than copper or galvanized pipe was used going to the spout The most common reason is that there is something restricting the water flow to the spout, e.g. solder or something lodged in the pipe. Something is impeding the flow of water to the spout and causing it to back up and go out the shower head. If this is the cause of shower-rise it is possible to remove the blockage by removing the tub spout; then, feeding a plumber’s snake or a speedometer cable up through the tub drop. The act of feeding it causes it to twirl and loosen the blockage. Be sure to flush the valve before reinstalling the tub spout. Be sure to check the tub spout itself for blockage. If none of these help, you may need to call a plumber. After the shower has been installed and the wall has been closed, there is little that can be done to remedy this situation yourself. Your faucet is equipped with a rotational limit stop that allows you to set the max hot water temperature on your faucet. Making the adjustment to this piece will raise the water temperature in the faucet. Here is a link to the How to adjust the rotational limit stop video. The 17 series portion of the video starts at 1:50 into the video. http://www.deltafaucet.com/shopping-tools/research/video-gallery/video.html?v=n2_uZ7wgV1I&cat= Thanks, Dave

Is there a longer attachment for the shower head

Asked by: george
Hi, George! Thank you for your question. The Delta Monitor T17438-RB Shower Arm measures 5 1/2" in length. We do have longer shower arms and all work with the shower head. For example, our Delta U4993-RB that measures 6" or the Delta RP40593RB that measures 7". We also do have 16" shower arms such as the RP46870RB. Best Regards, Rosanna

What diverter trim is needed for T-17438-ss Lahara Monitor17 series?

I am having a new tub and shower installed. I would like to add the 57021-ss handheld with bar as well. I believe that I need to also purchase the 50560-22 elbow along with the R1000-unbx valve and the R11000 diverter valve so that I can have the hand held work in tandem or separately. My question is, what diverter trim is needed for the R11000 valve to have everything match? I also will purchase the RP693-ss waste assembly but would like to know if that is everything I need or am I forgetting to purchase a part needed to finish this project? Also, I was told at one of the big box stores that even if I purchase the R11000 diverter, I still need to have the diverter at the tub as well. Is this true? Please explain. Thank you.
Asked by: Vicki
Hi Vicki, If you are adding just the Delta Faucet model # 57021-SS to your T17438-SS, you will need the T11800-SS diverter trim to complete your faucet. If you add another feature, like jets or another showerhead, you will need the T11900-SS. We recommend that you use a tub spout diverter when hooking everything up because if you divert the water using your R11000 diverter rough to your tub spout, there will be times when your showerhead and tub spout are on at the same time. Thanks. Jody

For a $300 trim set and using the Universal Rough In Valve, how long will it take to fill 60 gallons in an 80 gallon tub for a good soak? What is the flow rate out of the tub spigot? Thanks!

Asked by: Anonymous
Thank you for your question, Anonymous! The flow rate will depend on the trim kit used with the rough-in valve, the pressure in the home, and other factors. However, at 60 PSI the maximum flow rate will be about 6.0 GPM with the Delta Lahara Tub and Shower T17438-SS model. Best regards, Tanya

I just had the monitor model number T17438 installed in my new home. It’s one day old. And it’s showing dark water spots and turning dark colors. Is there a film covering that needs to be removed? This problem is in both bathrooms .

Asked by: Susan
Hello Susan, Thank you for your question about the Delta Faucet model T17438 Lahara® Monitor® 17 Series Tub & Shower Trim In Chrome. I apologize the faucet is showing water spots. I know that can be frustrating. We are happy to help! There would not be a cover on the faucet finish. Always blot dry any water from the faucet surface. Allowing water to evaporate on the surface can lead to a 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.
