When it comes to shower valves, Delta and Moen are the current market leaders. Both offer high-quality shower products for high-end clientele including shower valves. But are Moen and delta interchangeable?

Most people ask this question when looking for replacement parts for their Moen or delta shower valves.

In this blog post, we’re going to talk about two of the most common types of shower valves – Moen and Delta – and whether or not they are interchangeable.

We will also look at some of their similarities and differences to help you decide which brand is best for your needs.

Are Moen and Delta shower valves interchangeable?

This is actually a very common question.

It seems like Moen and Delta shower valves should be interchangeable, but as it turns out – they’re not.

In fact, there are several important differences between these two types of shower valves.

Delta vs Moen shower valves differences

1. Different dimensions

The delta and Moen shower valves are not interchangeable because they have different dimensions.

  • The first difference between these two brands of shower valves is the placement of the handles on either side of their respective bodies. Delta’s handle will always be located at its top while Moen’s will always be located on its back left corner.
  • Another is their hose attachment points and overall size/shape.
  • Their installation mechanism is also different. For instance, a Delta valve will need to be installed on the left side of the tub while a Moen one needs to go in from the right side.

2. Different designs

Another reason is that these two products have different designs.

If you try to use a Delta shower valve in a Moen shower, for example, the water pressure may be too strong or too weak.

It’s important to make sure that you buy the correct type of valve for your particular shower so that you can enjoy a relaxing and refreshing experience under the spray.

3. Different mechanisms

Moen and delta shower valves have different mechanisms.

Delta shower valves use a cartridge system, while Moen shower valves use a ball system.

Because of this, the two types of valves cannot be swapped without potentially causing damage to either the valve or the plumbing.

If you’re looking to replace your shower valve and you have either a Delta or Moen model, it’s important to make sure you buy the correct type of replacement valve in order to avoid any problems down the road.

4. Types of fittings

Delta and Moen valves are not interchangeable because they use different types of fittings.

If you have a delta valve, it will most likely be made for 3/8″ pipe threading.

A Moen is more compatible with 1/2″ compression fittings in the United States and Canada, but may also come with both threaded and compression fittings in other countries.

This means that if you want to switch from one brand to another type of plumbing fixture or accessory without purchasing new pipes, then there’s no way around replacing your entire system.

FAQ about are Moen and Delta interchangeable? 

Q1. Is Moen better quality than delta?

Honestly, Delta and Moen are both reputable brands of shower valves that have been around since the early 20th century.

It’s difficult to say which is better because they’re so similar in quality. However, if you need a recommendation for one over the other, we would suggest going with whichever company has your preferred style of faucet set up.

Q2. Are delta shower valves universal?

Delta shower valves are not universal because they do not have a standard size.

They come in many different sizes, shapes, and colors which can make it difficult to find the right one for you.

However, if you know that your valve is round or square then this will help narrow down your search considerably.

Q3. Are delta and Moen shower cartridges interchangeable?

So, are delta and Moen shower cartridges interchangeable?

The answer is yes and no. In most cases, the cartridges will be interchangeable even with other brands, but there may be some exceptions.

But if you’re not sure whether your cartridge is compatible with another brand of shower valve, it’s best to consult a plumbing professional.

They should be able to help you determine if your cartridge can be swapped out and which replacement cartridge will work for your specific valve.

Q4. Do plumbers prefer Delta or Moen shower valves, and why?

When it comes to durability, Moen valves perform better than Delta valves, mainly because of their material.

Moen valves also resist corrosion and are not affected by hard water because of the nickel brushings.

In terms of the availability of repair parts, Delta parts are more recommendable.

The Delta universal kit is interchangeable between the Delta Trim Kits, while Moen parts are not interchangeable between the different models of valves.

Moen valves are also more challenging to repair because of the rough valve fittings. For instance, the Posi Temp control valve from Moen is notably more difficult to repair as compared to the other Moen models.

However, Posi Temp controls more water volume and lasts longer before it needs repair or replacement,

Both Delta and Moen valves are reliable and certified, hence equally preferable when it comes to efficiency.

Delta valves combine technology and versatility, whereas Moen gives durability and performance. Both Delta and Moen valves come with a product lifetime warranty.

So honestly, I don’t know why plumbers would prefer one over the other. Both are good brands and both have their advantages, so it’s really up to preference.
