Hi Thank you for the detailed response. Initially I was considering an integrated diverter, Delta or Brizo and was advised some of the models would work with the tub and some would not, even though the specs on-line required the same rough-in! Interesting that the R22000 specifically states the longer fill times. I've heard back from the showroom and they say Delta confirms plumbing to the diverter is fine but they still did not explain the plumbing required . My easiest option is to get a diverter tub spout so the showroom is focusing on replacement products for that option.

I have a second bathroom due to be renovated with the same set up using Grohe valve and diverter. The specs for the Grohe diverter show a bathtub icon on one of the ports so clearly indicates it is intended for that plumbing. I haven't opened the box to determine if that port is larger. I was waiting for a Grohe technician to call me back to confirm in case I need to return all those products.

I’m following since I’ll need exactly same set up.

I'll try to update on the Grohe products but so far I have no answer for Delta products. I am resolving my issue by installing a diverter tub spout in that bathroom because even if Delta told me that plumbing the tub spout to the diverter will not cause a significantly slow tub fill, I'm not sure I would believe it at this point.

How did this all turn out???

J Marrow We had the plumber install a tub spout with diverter rather than redoing the plumbing from the skinny closet. I had lost all confidence in this plumber and was afraid he would make a bigger mess. It's a pain to pull down the diverter with wet hands. I still have the 3 Way/6 Function Diverter. The positions that intend to use the plugged port #3 (that should have been the plumbed to the tub spout) result in no water flow. A guest over Christmas was so confused as to how to use the shower. After hearing the water go off and on several times we had to knock on the door and explain how to use it.

I'm remodeling another master bath with a new plumber. He offered to replumb everything from the skinny closet at a cost of $800. I still don't know if plumbing the tub spout to the diverter will result in a slow filling tub. The showroom insisted that their contacts at Delta are more knowledgeable than the Reps that I would have spoken to and stand by their product configuration and that the tub flow would have worked fine.

I also asked my new plumber about changing out the diverter to the 2 way/3 function trim and cartridge and he said that wouldn't solve the problem. He also said he couldn't do that without disrupting the tile. He said the cartridge is installed before the wall is tiled and has installed the cartridge in the master bath with the wall open. So I'm really confused now. I thought I could at least correct the non working diverter positions so we wouldn't risk someone putting the diverter in the plugged port #3 position and thinking that the water was shut off.

Curious if you have any insight!

I'm in the same situation and even reading the above is making my head hurt. I started out wanting a rain shower, hand held, and tub spout but am almost ready to give in and just replace what is currently there.

Curious to hear the end of this story as I have the same questions about best diverter set up !

Hi Esme

Would love to help you out but not sure what additional information I can provide. What we have works, a diverter tub spout, but It is frustrating when guests use the shower because to send the water to the shower you must pull down on the bottom of the spout and it is not obvious that this piece is there or how to use it. I had wanted a single 3-way diverter that would have diverted the water to the 3 outlets but my plumber goofed from what he told me to purchase for fixtures to the way his workmen plumbed the pipes and valve.

I have replaced the 3-way/6 function trim/cartridge which had 3 positions with no water (what would have been tub only, Tub + shower head, Tub + hand held) with a 2 way/3 function diverter. My new plumber was refusing to install the 2-way diverter stating that it wouldn't work properly despite the install instructions that the same rough in valve worked with either the 3-way or 2-way. The Trim Kit included the cartridge so the new 2-way fixture included a compatible cartridge. He installed it, just to prove me wrong, and it worked as I expected! He said he had a customer with the same issue and took the instructions and box so he could recommend how to fix her problem. These are Brizo/Delta Valves and Trim.

I don't think the set up I ended up with is the best diverter set up. However, I received conflicting feedback from the Showroom, who consulted their Delta Rep, and the Delta Customer Service, that I contacted, on whether or not Option A (3-way diverter) would work.

Good Luck! I really felt like I was the first person to want a tub, shower and hand held configuration with the amount of confusion with the Showroom, Delta and my Plumber.

Thx for the follow up! It does seem like this should be a pretty basic question 😆

Boy do I need help from the original author! I purchased Grohe products: a shower head, a handheld shower and a divertor tub spout. I have a Grohtherm dual function 2 handle thermostatic trim piece and the Grohe Rapido Smartbox rough in valve. Grohe told me that I could use a 2 function trim if I had a tub spout with a divertor. The plumber installed the system but water does not flow to one of the items.. He blames me and says I needed a 3 function trim. I think he plumbed the pipes incorrectly for use with a two function trim. The tile job would have to be destroyed to redo the pipes to use the dual function trim. He said I need to buy the 3 funciton trim to make the system work. This has been a plumbing nightmare.

Hi Demo58

I sympathize with you. (You have the opposite issue that I had-sounds like your plumber plugged the bottom port and not Port #3.) If you had all the products on hand, as I did, I don't understand why your plumber didn't confirm the required plumbing based on the products purchased. I know how frustrating that is! Is there access to the plumbing from the wall behind?

Unless you have a particular reason for wanting a tub diverter, it's convenient to have all 3 water functions controlled by the one diverter, which is what I wanted. In my case, I had purchased the plumbing products from a supplier that the plumber works with all the time. He reached out to them and I was able to return my original non diverter tub spout, although I believe he made up some other reason why it didn't work. They would not refund me for the 3 function diverter trim for a 2 function because they said it still worked with the incorrect plumbing and they were not responsible for the plumbers error. (I purchased the 2 function and the plumber refused to install it.) Perhaps you can return your 2 function trim for the 3 function. Do they both use the same rough in?

Good Luck!
