Moen is known for original and reliable shower valves. So, it’s tempting to consider the shower valves whenever you want to upgrade or replace your shower valve. But are Moen shower valves interchangeable?
Unfortunately, No! Moen shower valves are not interchangeable, neither within the brand nor with other brands. Essentially, that’s because their trim plates and designs are different.
So, before you can upgrade your shower valve with a Moen fixture, you should ensure the replacement matches the older version in trim plate and design.
The shortcut is to look for the model number on your existing shower valve. If it’s a Moen and then look for its replacement online.
To help you with that, I’ll provide you with a few tips for identifying a Moen shower valve so that you can get the ideal replacement. But before I do, let me explain more why Moen shower valves are not interchangeable.
2 Reasons Why Moen Shower Valves Aren’t Interchangeable
Here are two reasons Moen showers are non-interchangeable:
1. Trim Plates Are Different
For shower valves to be interchangeable, their trim plates have to match. Sadly, that’s not the case with Moen valves. Moen shower valve trim plates are different from other brands, making them non-interchangeable.
In that case, you’ve to take note of the model number of your Moen valve and look for a matching replacement. If you don’t, you’ll likely buy a replacement that may never fit.
2. Overall Designs Are Different
For a long time now, Moen has been making shower valves that assume three different types of designs;
- Standard Moen shower valves – Though Moen doesn’t make these valves anymore, they remain among the most popular choices on the market. Standard Moen shower valves are distinguished by the corrosion-free body featuring a sleeve, O-ring, and stem.
- Moentrol Moen shower valves – These Moen shower valves work by pulling out the control knob to allow the shower water to flow out. On average, Moentrol valves enjoy a flow rate of about 7.5gpm.
- Posi-Tempo Moen shower valves – These shower valves by Moen enjoy a slightly lower flow rate than Moentrol, about 6.3gpm. The difference is that they have a unique temperature control knob to allow you to switch hot water on by a quarter turn.
So, generally, since these valve designs are different, you cannot swap one for another and expect it to fit perfectly. Yes, it may work sometimes, but it’s never a given.
Thus, unless you know your way around shower valves and can manipulate them expertly, you should get a perfect replacement.
Are Moen Shower Valves Universal?
Moen shower valves look alike, especially those of the same design. Their trims, however, are very different, which means you cannot interchange them. So, no, Moen shower valves are not universal.
In that case, you cannot change Moen shower valves with other brands, for their designs are different. Additionally, you cannot interchange them within the same brand unless they accept the same trim kits.
Overall, shower fixtures like shower valves are rarely interchangeable. You have to find a matching replacement within the same brand. So, in the case of Moen, the replacement should also be Moen.
How to Identify Moen Shower Valves
Remember, it’s critical to fit the correct Moen shower valve, and it starts with identifying it. Here are the steps to follow:
- First, ensure the old shower valve is a Moen type. In that case, look for the letter M on the escutcheon plate. If it is, then proceed to the next step.
- Note down the year of introduction. It should be around 19 something. That’ll help you find a matching replacement.
- Note down the handle operation and then the location of the escutcheon screw.
- Now use the Moen valve chart below to determine what Moen shower valve you have.
