PRODUCT FEATURES
The Delta® MultiChoice® Integrated Shower Diverter consolidates custom shower design with its consumer-preferred streamlined style eliminating the need for an additional diverter valve. The contemporary round style is a smooth take on modern geometrics, offering a fresh look which can complement a wide range of decor. With three popular style choices to coordinate with any bathroom décor, it provides you the flexibility to select the type of custom shower functionality you prefer. With the MultiChoice® Universal system, you have the freedom to upgrade style and functionality later. And, because there’s no need to alter plumbing behind the wall, you save time, effort and money on future renovation updates. Delta's dual-function thermostatic valve cartridge keeps water temperature consistent (within 3.6°) by actually measuring and monitoring the temperature of the water. Temperature can be set in order to remain consistent shower after shower.
  • 3-Setting diverter trim
  • 2-handle trim with separate temperature dial
  • Control volume and water temperature independently with two separate handles for more refined control of your shower experience
  • TempAssure Thermostatic cartridge measures and monitors the temperature of the water and automatically adjusts to maintain a more precise water temperature
  • Trim kit only, must order MultiChoice® Universal Valve separately to complete the unit
  • Meets standards set by Americans with Disabilities Act (ADA)

Rated 5 out of 5 by from Set the temperature and enjoy I installed this product more than a year ago, the valves were easy to install for a DIY, the trim was easy to put on. I really enjoy the fact that all you have to do is set the temperature one time, and every time you turn the water on no matter how high the pressure is. The temperature is the same. The finish is great, and a terry cloth wipe down after every shower, and it looks like new even a year later, with no watermarks.

Q&A

Can this valve be used for tub, showerhead and handheld? 

Asked by: Krista
Hi, Thank you for your question. We do not recommend using a diverter valve with a tub spout as it will decrease the pressure and amount of water available to fill a tub. For tub spout installations, we recommend using a Univeral Multichoice rough in valve like the R10000-UNBX. This valve will allow you to install a diverting tub spout on the bottom port as well as connect to a diverter trim on the top port. https://www.deltafaucet.com/bathroom/product/R10000-UNBX https://www.deltafaucet.com/bathroom/product/R11000. Please feel free to contact us directly for technical information at 800-345-3358. 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. Thank you for being a loyal Delta Faucet customer.

Can you use this with shower head and handheld shower combo?  I’d rather have one piece that does everything instead of the two separate diverters but haven’t seen this shown in any photos/configurations.

Is the cartridge "guts" plastic or ceramic. Can this be used for a combination shower head and hand held shower system?

Asked by: Kenn
Hi Kenn, Thank you for your question about the Delta Faucet model T27T859. The included cartridge has a thermostatic valve that uses a wax element to read the temperature. The cartridge materials also include brass and plastic. The integrated diverter is for up to two shower features.

Can this diverter be used in a configuration of  1 setting to control a shower head, 1 setting to control a hand held body sprayer and 1 setting for another shower head ?

Asked by: JayTeasey
Hi JayTeasey, Thank you for your question about the Delta Faucet model T27T859. The 3-setting diverter is used with two shower features. For three shower features, I recommend the similar model T27T959. A 6-setting diverter has three individual settings and three shared settings. https://www.deltafaucet.com/bathroom/product/T27T959.html Please reach out with any additional questions!

I'm looking for a rough-in valve and diverter combination that would allow me to push water to 1 shower head, 1 hand-held wand and tub spout. I want tub spout with NO integrated diverter - so that all the controls would be wall mounted. Is this possible?

Asked by: Mike
Hi Mike, thank you for your interest in the T27T859! We do not recommend installing a tub spout with the R22000 Integrated rough valve as the flow rate from the spout would be lower than a standard installation. Alternatively, you can install an R10000 and R11000 valve with corresponding trim kits. The tub spout should be connected to the bottom port of an R10000 valve to provide sufficient flow to fill a tub. Please view the links below of the valves. https://www.deltafaucet.com/search-results?q=r10000&lang=en_US https://www.deltafaucet.com/parts/product/R11000.html Please contact us directly if you have any questions or need additional assistance.

We want a shower head, hand-held shower, & rain shower (ceiling) that will work individually, not at the same time. Can we use this rough-in valve (R22000) & T27T859-BL trim for this application. Is there a cartridge or trim kit that would work for this.

Asked by: FredZ
Hi FredZ, Thank you for contacting us at Delta Faucet! Please accept our sincere apology for the inconvenience you are experiencing. Here is what we can do to resolve your issue for you. For this custom installation we actually recommend model T27T959-BL Contemporary TempAssure® 17T Series Valve Trim With 6-Setting Integrated Diverter In Matte Black as this will allow you to switch between showering components without them running at the same time. You will still need to install the R22000 integrated rough-in valve. Please see the following link for more information. https://www.deltafaucet.com/bathroom/product/T27T959-BL.html https://www.deltafaucet.com/bathroom/product/R22000.html Please contact us directly by phone at 1-800-345-3358 or email at customerservice@deltafaucet.com if further assistance is needed at this time.   We appreciate your loyalty to Delta Faucet Company.

After 6 months of use the hot water pressure began to drop to the point where had no hot water flow. Then cold water pressure dropped to almost nothing. What part do I need to replace?

Asked by: Wade
Hi Wade, Thank you for contacting Delta Faucet Company! Please accept our sincere apology for the inconvenience you are experiencing with your Contemporary Two Handle TempAssure® 17T Series Valve Trim With 3-Setting Integrated Diverter In Venetian Bronze MODEL#: T27T859-RB. Here is what we can do to resolve your issue for you. Low flow is caused by debris or blockage, we would recommend flushing the shower system, please see the step-by-step instructions below. To flush the open valve without the cartridge, please follow the directions below. 1) Remove the handle by loosening the set screw on the side of the base of the handle. The set screw is either a 1/8" or 3/32" Allen screw. So you will need to use the appropriate size Allen wrench to loosen it. Loosen it just enough to be able to easily pull the handle off. * Note. If there is calcium build-up at the base of the handle, it may be necessary to soak it in a 50/50 solution of vinegar and water. Simply saturate the rag with the 50/50 solution, wrap it around the handle base and place a plastic bag over it. I would recommend do this the night before removing the handle. 2) After removing the handle, remove the trim sleeve. 3) Then you will need to remove the bonnet nut. The bonnet nut is the threaded ring at the valve opening. It unscrews counterclockwise. You will need a pipe wrench or a pair of channel locks. 4) After removing the bonnet nut, you will need to pull the cartridge straight out. You may need a small, skinny bladed screwdriver to wedge in between the lip of the cartridge and the valve to help start it out. 5) Once the cartridge is removed, you will have an open valve body. 6) Next, shut the shower door or curtain and turn the water on to the valve. Water should gush out, much like an open fire hydrant. Have someone observe if there is good water pressure coming out of the valve and let it flush for 30 seconds. 7) Re-install the cartridge and re-assemble in reverse of how it was disassembled. The Tub/Shower should then have a good flow. 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
