Is "Adia" a shower valve manufacturer?

[tflood]

Hi all,


I’m hoping to get help identifying and sourcing replacement parts for a 3-handle shower/tub valve system in my home.

The house was originally built in the late 1930s, but the bathroom in question was added during a later remodel—unfortunately, I don’t have a date for the addition. The shower has a 3-handle setup with a tub spout and diverter. The handles are chrome, and the escutcheon/knob centers are stamped with “ADIA.” I haven’t had any luck finding a manufacturer or model info related to this name.

Here’s what I know:

• The hot and cold valve handles are spaced approximately 12 inches apart, which seems less common than modern 8-inch or single-handle setups.
• The diverter stem broke off and needs to be replaced.
• I’ve attached photos showing the valve layout and a close-up of the handle.
• I haven’t removed the escutcheons yet to examine the valve body or stems behind the wall but can do so if that helps with ID.

Any help identifying the valve body or diverter stem—or suggestions for compatible replacement parts—would be much appreciated. If this is a private label or discontinued brand, I’m open to retrofitting with a universal diverter stem or swapping the valve system if necessary.


Thanks in advance!

Dornbracht made a line called Adia.. The hot and cold stems are very similar and inter changeable with Grohe. I don't know if the diverter stem is inter changeable.
