Best PEX Shower Valve

We have come up with the best PEX shower valve reviews to help you choose the most suitable valve according to your needs.

This article will also cover crucial factors to consider before buying a PEX shower valve.

See us revealing what these valves have to offer before you head to buy.

Let’s get started.

What to Look for Before Buying the Best Shower Valve for PEX?

Best Shower Valve for PEX

To be honest, you need to look for many different things before buying the best PEX shower valve. If you are new to this, things can seem overwhelming. We have simplified the necessary factors for your convenience.

Have a look.

1. Valve Type

Though all the PEX shower valves do the same thing, there are varieties in their types and working principles. Some valves have a pressure balancing feature to keep the water flowing at a constant pressure. This ensures smooth water flow out of the faucets.

Some valves are thermostatic, meaning they can control the temperature of the water. You can set the water temperature at your desired position, and the valve will take care of the rest.

Transfer valves are also used for PEX, but they aren’t that common. Some valves will combine the thermostatic and pressure balancing features, so you will get both in one valve.

2. Automatic and Manual Valves

Thermostatic valves can be easily controlled to get the optimum temperature. The biggest benefit is that you don’t need to alter the faucet position repeatedly. Once the water temperature has reached the desired position, the valve will automatically shut off.

But manual valves can’t do this. So, you need to turn the faucets on or off as required manually.

3. Number of Connections

It is crucial to ensure the valve can be used with different trims at the same time. If there are multiple inlet connections, you can use the valve to control both the water temperature and pressure.

Multiple outlet connections will allow you to use the valve with different showerheads without altering the plumbing system. Most valves have universal half-inch connections, but you can also get a 3/4 PEX shower valve.

4. Material and Build Quality

As PEX valves are installed in the water supply system, they should be made of high-quality material to sustain for a long time. Most PEX shower valves are made of brass as it is very durable in this specific use case.

No matter what valve you buy, it should have no leaks to maintain its performance throughout. The valve will continue to maintain a smooth water flow only if it is leakproof.

5. Price

This might not be a big factor in making your buying decision, but you should always get good value for your money. Some valves are unnecessarily pricey, so you can avoid them. Get something that offers solid performance at an affordable price.

How to Install Shower Valve With PEX?

How to Install Shower Valve with PEX

If you are doing it for the first time, it will be better to check our simple step-by-step guide on how to install a shower valve with PEX. Here you go.

  1. The first job is to wrap inlet ports with thread tape. Give them a good wrap so that the PEX fitting sits tightly.
  2. Then install the PEX crimp fitting in the inlet port to connect your PEX pipe.
  3. Once this is done, put the plastic flange of the valve on and mount it on the desired surface. Make sure the back of the valve is aligned properly.
  4. Take hot and cold supply pipes and use a crimp tool to connect them to the inlet ports of the valve.
  5. Then you can install cartridges and shower trims of your choice.


This section is all about finding answers to some frequently asked questions. Let’s check them out.

1. Can I use PEX for the shower valve?

Yes, you can use PEX for the shower valve. But you need to use proper fittings to connect PEX pipes to shower valves. Most valves will have a crimp-type PEX connection. So, use the right fitting to connect PEX pipes.

2. What size PEX for a shower?

There is no hard and fast rule for this. You can even use one-inch PEX if it matches the valve. But a lot of water will be wasted if you use bigger pipes. Using something from 3/8-inch to 1/2-inch will be good enough.

3. Can I use PEX for my tub spout?

Though you can use PEX for tub spouts, we don’t recommend doing so. This is because tub spouts are usually heavy, and PEX pipes might not always support the weight of the spouts. So, it’s better not to use PEX for tub spouts.

4. Does PEX lose water pressure?

PEX plumbing has been very popular lately. One of the main reasons behind their popularity is that PEX plumbing holds the water pressure. In fact, this system holds pressure better than any other system.

Final Word

Getting water from shower faucets at the right pressure and temperature feels satisfying. But we often overlook how many things go into making a system that works fine without any issues for years.

With the increasing popularity of PEX plumbing, PEX shower valves are taking over the place. Though there are many valves in the market, picking the right one needs a bit of experience, which most homeowners don’t have.

We hope our detailed guide will help you know the important factors you should consider while buying a shower valve. And the reviews will make it a lot easier to choose the best PEX shower valve.
