Rated 4 out of 5 by from Nice shower/tub unit Selected this for the thermostatic control and dual controls in the one valve. Construction of the valve unit is very nice and solid, the shower head is plastic and feels 'cheap' compared to it, but if it sprays well, I'll be happy. I haven't installed this 100% yet, so I cannot speak of it's performance, but since the base valve components are universal, as long as the shower head puts out a good spray pattern, it should work just fine in our guest bathroom.

Rated 4 out of 5 by from Great faucets but.... Gosh, over spending more than $500.00 on a very similar set, I was absolutely sad to see the decorative plates and finials, the shower head, and lip pieces of the tub faucet were all plastic! I have to say, after 10yrs, it still looks very nice and I love them. KEY THING is to dry it off after use because after 5 or so applications of CLR, I finally got the hard water spots off, but they are coming off. I polished with a drop of olive oil with a soft cloth just to make it shine - perfect! I love the hand held shower head, we have a super large custom tile tub and that really helps not only with a great spa like shower, but cleaning too! We just purchased a chrome finish shower head and hand held additional head for a spare bath ($65) and it too was all plastic - works nice too, but what happened to good old metal?

Rated 2 out of 5 by from Not all metal I thought this price point would be all metal construction and the tub spout is all plastic. So I am disappointed.

Q&A

I have the older 1700 series valve and want to find a newer trim kit in bronze that will work, do I have any options

Asked by: Reed1639
Hi Reed1639, Thank you for your inquiry! As long as the screw holes on your original large round escutcheon plate are at the 1 and 7 o'clock positions and you do not have a push button shower diverter directly below the off and on handle, then any of the Delta tub and shower trim kits that start with a T17, except for the T17T series trim kits will interchange for you. The Delta Lahara 17 Series Trim T17438 is available is Venetian Bronze, Chrome, Stainless and Champagne Bronze finishes. The cartridges that come with the new trim kits will not fit your valve body (if top of original cartridge is white), so you will need to reuse your existing cartridge (RP32104, white top). https://www.deltafaucet.com/bathroom/product/T17438-RB Best regards, Tanya

Temp adjust not part of flow control ?
Asked by: LEN
Hi Len, Thank you for your question! The T17T series gives you the option to control your volume separate from the temperature. Best regards, Brandis

Will this work with an older 1700 series monitor rough in and valve or do you have to upgrade to the newer rough in valve setup?

Asked by: Reed1639
Hello Reed1639! Thank you for your question. The Delta Lahara TempAssure 17T Series Tub and Shower T17T438 faucet trim kit and cartridge will not install in an older Delta 1700 series valve that was installed before 2006. You would need to replace the rough-in valve with the newer Delta MultiChoice Universal Rough-In R10000-UNBX valve assembly. https://www.deltafaucet.com/bathroom/product/R10000-UNBX Best regards, Tanya

Is the on/off in the shower in the volume handle or in the temperature handle?

Asked by: LC
Dear LC, Thank you for your question. The bigger lever of the Delta Lahara TempAssure Tub and Shower trim T17T438 faucet, is the volume or the on/off handle.The front lever controls the temperature. Best regards, Tanya

What materials are used?

What materials are used in the construction of the handles and tub faucet? Is the plating over metal or plastic?
Asked by: buyer
Hello buyer, Thanks for your question! The T17T438 has a metal volume handle, temperature cap, and escutcheon. The tub spout and the shower head are non-metallic. I hope this helps!

TempAssure

Is this true thermostatic control? Is there more than one type of thermostatic cartridge? I like Linden best, but it doesn't look like the TempAssure is available with Linden.
Asked by: fsf
Thank you for your question. Delta Faucet model # T17T438-CZ has a true thermostatic cartridge. Once you set the temperature, it will not vary within 3 degrees of where you set it. I will pass along your suggestion to manufacture the Linden series with a thermostatic cartridge.
