Rated 5 out of 5 by from Quality products as always! Awesome quality and beautiful in my shower.

Rated 5 out of 5 by from works well, they need to return to a plaster shield. Diverter worked well with only a few bugs. Diverter no longer comes with plaster shield making getting it flush more difficult, the was also no way to reach thru from the front to put screws into back wall. Basically wound up screwing the valve to a board then nailing the board in flush.

Q&A

Does this come with the valve, as well as the cartridge? Or must the valve be purchased separately?

Asked by: IHK_67
Hello IHK 67, Thank you for your question. The Delta Trinsic T11859-BL 3-Setting Diverter Trim comes with the RP51918 3-functions diverter cartridge assembly. This cartridge will allow you to switch between two shower components individually as well as a shared setting. The Rough-In Diverter Valve R11000 does need to be purchased separately. https://www.deltafaucet.com/bathroom/product/R11000 Best regards, Tanya

We want to use a rain head, hand head and regular shower head with these but we want them to work individually. Will we need the non shared cartridge or would we need to go up to a 3 port diverter trim instead of a 2 port?

Asked by: trey
Hi, trey! Thank you for your question. The Delta T11859-BL will work with only two shower components. We recommend to use T11959-BL, this will allow 3 shared settings and 3 individual settings, 6 settings in all. Best Regards, Rosanna

Does this diverter come with a backplate?  If not does it require a backplate?  

Asked by: Cilla
Thank you for your question, Cilla! Model T11859-BL does include the back escutcheon plate with this trim. We strongly recommended installing this plate to keep a water-tight seal between the trim and the wall. https://media.deltafaucet.com/PartsDiagram/DPD-B-T11800_B.pdf Best regards, Edward

What size hex key is needed for assembly and is there a temperature regulator that can be adjusted?

Asked by: bbbq
Thank you for your question, bbbq. This should take a 3/32" Allen wrench. Most of our set screws are either 3/32" or 1/8". Best regards, Jon

Hello, does it come with a cartridge included? And if it doesn't, which one would be the correct one for a Shower head and Handshower? Thank you!

Hi! Im trying to install this diverter in my shower but in my case my hand shower is at my right side and the 3 positions diverter only works on my left where I don't have anything, It's possible to use it on the center and the right positions?

Asked by: nmbatino
Hello Nmbatino, Thank you for your question. To have the Delta 3-Setting Diverter Trim T11859-CZ function properly, you would need to cap off the right side port of the diverter valve. If you decide to cap off the left port instead of the right port, you will need to purchase separately the 6-setting RP51919 diverter cartridge. This would provide you with your three function settings and a few dead spots. Best regards, Tanya
