Is Moen Doux Upgrading to M-CORE Valves?

Doux M-CORE Update

Moen is upgrading their tub and shower valve system, and for most homeowners and all contractors, this is great news. M-CORE valves are easy to install and give you so much flexibility to upgrade down the road. Some people who may have concerns are homeowners with their Doux showers built on the old Moentrol system. What happens if you need to replace your Doux trim? Do you have to replace the valve, too? Or maybe you want a Doux shower with M-CORE. Is that available? These are questions that need to be answered.

Can I Upgrade Doux Trim to the M-CORE Valve System?

Doux moentrol trim vs m-core trim

Yes! But only with M-CORE Series 3. You can see all Doux M-CORE trim options here. You can get Doux valve trim, transfer trim, valve with transfer trim, as well as complete shower and tub and shower trim options. The designs aren't exactly the same, but they remain true to the spirit of the Doux collection. On the left, we have old Doux, and on the right, we have the new:

Is the New Trim Backwards Compatible?

No. If you want to install new Doux trim in your shower, it will have to be on an M-CORE valve. The reason is it's a completely different connection and cartridge system.

Will Moen Still Make Doux Trim for Moentrol Valves?

No. If you want to install new Doux trim in your shower, it will have to be on an M-CORE valve.

What's Different About the New Doux Trim?

It looks very similar to the old trim, except the new Doux designs pop a little more. They also do a better job of concealing hardware and the other parts of the valve that you don't want to see.

How Do I Know if My Doux Shower Is Built on M-CORE Valves or Moentrol?

m-core valve vs moentrol

Although you may not know much about what you're looking at when you examine a valve, it's pretty easy to tell the difference. Both valves are made with brass bodies, but M-CORE (pictured on the left) has more of a polished sheen to it. Whereas, Moentrol (pictured on the right) has more matted brass color.

Note: the pictured valves are for valve and transfer assemblies, which allow you to divert water from the tub to the shower, and vice versa. If you don't have a tub, it's just a shower installation, then the valve configuration won't include the top part (diverter).
