Need HELP in Identifying this Rough-In Shower Valve. Grohe #34-124

Hi folks,

I am finally getting around to installing the shower trim kits in my master shower (dual-head, dual valve). I'm really hoping that someone can help me identify the rough-in, as I believe it to be mainstream. My rough-in work was done by my plumber who unfortunately is no longer in the business nor the area and is unreachable, so I'm reaching out to this forum, which has been incredibly helpful in the past to see if someone can help direct me.

My guess is Moen or Delta, but not sure.

The third photo (kinda blurry) is one of the handles only. On each of the two faucets, there is a Cold and a Hot shutoff and the main temp control valve.

Can anyone tell by the photos or is there more info I can provide?

Thanks in advance,
Chris

It is NOT Moen, Delta, Kohler, or any other "mainline" manufacturer, but will check with my "weird faucet" expert to see what he says.

Does anyone have any clues then on what this is? Or where I can go for trim kits?

TIA,

It is a Grohe #34-124, which is being discontinued, but for now their thermostatic trim kits will fit it.
