  • Material: Brass
  • Finish: No finish

This Delta unit is a 1-way control unit that is one of the best mixer shower valves when it comes to price to performance ratio. You also get quite a lot of versatility with this model as you can purchase it in different numbers in the form of “packs” depending on your need.

Since this shower valve is made from brass metal, it is heavy-duty, durable and long-lasting. It is also made in the USA so you are getting a lot of quality with this purchase. One good thing about this shower valve is its shape that has a flat back that will allow you to easily make the connections inside your wall without much difficulty.

The threaded connections are also standard as this model uses regular 1/2 inch plumbing threads so you will have no problem installing it to your plumbing system. For versatility, this unit also accepts thermostatic cartridges to regulate the temperature of your shower or dual cartridges for shower head flexibility.

Pros:

  • Good price. Value for money
  • Versatile. Accepts single, double or thermostatic cartridges
  • Easy to install because of the flat design that allows it to sit flush to the wall

  • Finish: Polished Chrome

Not everybody can afford a very expensive shower valve. This is where models like the KES K1140B comes into action. Here we have a very inexpensive shower valve that has a 1-way control and made from a single piece of brass.

So, you will have no problem when it comes to the durability of this shower valve. It uses a regular G 1/2 male and female threads for installation so no problem there as well. When it comes efficiency, you get provided with rubber gaskets that will prevent it from leaking, even if you have a high-water pressure in your shower.

For control, there is a small lever on this shower valve that will allow you to easily perform a quarter turn so as to switch the water supply on or off. Base on the price, and since this is a barebones valve that does not come with a handle or trim plate, we rate this KES unit as the best rough in shower valve in this review. It is simple and works beautifully well!

Pros:

  • The most affordable shower valve in this review
  • Easy to switch the water supply on or off

Types of Shower Valves

Types of Shower Valves

There are 3 main types of shower valves on the market. Here is an overview of those different types of valves so that you can choose the best shower valve for your need:

Thermostatic Valve: The thermostatic valve is a type of valve that will prevent the temperature of the water from changing. In a common shower without a thermostatic valve, any change in the water pressure will directly result in an increase in the temperature of the water.

For example, if you flush your toilet while showering, the temperature of the shower will rise sharply which can cause scalding. This is a problem that the thermostatic valve will prevent from happening.

Pressure-Balancing Valve: Most showers are at the mercy of the water pressure delivered by the plumbing system. Sometimes you get a high-water pressure when no one else is using water in the house, and sometimes you get a low water pressure when the demand for water is high.

What a pressure-balancing valve does is help stabilize the pressure of the water. This results directly in not only getting a consistent and constant water flow but also a more stabilized water temperature regardless of water usage in the house.

Diverter Valve: As its name suggests, the diverter valve is a type of valve that will divert the flow of water to a specific outlet. For example, if you want to switch between your hand-held shower head and your fixed showerhead using your faucet, you can quickly and easily do it with a diverter valve.

A big advantage of the diverter valve is that it prevents you from instilling complex plumbing infrastructures or having to install the diverter that usually comes with your shower kit. Most of the time, the dedicated diverter valve will be superior both in durability as well as efficiency to the diverter that comes with your shower head unit.

How to Buy a Shower Valve

How to Buy a Shower Valve

1. Compatibility

First and foremost, you need to make sure that the shower valve is compatible with your plumbing system. Specifically, look for the size of the connectors. Most of the time, a typical shower valve will use a 1/2 inch connection.

2. Controls

Eventually, the price of the shower valve will depend on its controls. The more controls it has, the more versatile it will be but it will also be more expensive. Controls in a shower valve range from 1 to 3. As a general rule, a model with more controls will provide you with more versatility.

As an example, a shower valve that has one control will be able to control the amount of hot water flowing through the valve. If it has 2 controls, it will not only be able to control the amount of hot water flowing but also the pressure of the water. For a model with 3 control units, it will do any of the above as well as give you control on which outlet you want the water to flow.

3. Outlets

The number of outlets that the shower valve can control is also important. Especially if you have more than one shower head that you need to provision with water. For example, you may want the shower valve to supply your handheld showerhead as well as your fixed rainfall showerhead.

In this case, you will need a shower valve that comes with 2 outlets. Similarly, if you use 3 showerheads in your bathroom then you will need a model that has 3 outlets.

4. Material and Design

The material and the design of the shower head will dictate 2 things. The durability of the showerhead as well as its efficiency in controlling the water flow as well as the water temperature.

In most cases, some of the best mixer shower valves on the market are made from brass which is an excellent material that does not corrode, has good temperature resistance and is highly durable. However, the main disadvantage of Brass is that it is generally more expensive.

If you are on a budget, you can still go with a shower valve made from an ABS plastic and it will still get the job done. However, it will not be as efficient, performing or durable as a model made from brass.

In addition to the material used in the construction, the design of the shower valve is also extremely important because it will dictate how efficient it is.

A well thought and good design will prevent your shower valve from leaking even under high water pressure or high-water temperature. It will also have a superior temperature control over the water flow as well as deliver the water in a more consistent manner to the outlet.

5. Handle Options

A few shower valves come as a kit that includes accessories like a stainless-steel handle that will allow you to quickly and easily interact with the shower valve. The handle is also usually made from stainless steel but can come in different colors so as to match the color scheme on your bathroom. If you don’t want to purchase those accessories separately, then it is best to go with a shower valve kit that includes everything.

6. Easy to install

The shower valve is a plug-and-play pumping accessory that does not require a lot of skill to install. If you can connect 2 water pipes together then you will have no problem installing the shower valve. However, it is still good to see if the manufacturer makes any mention of how easy it is to install and if it comes with an instruction manual for the installation. This is especially important if you have no experience installing a shower valve before.

7. Brand

In order to ensure that you are getting a quality, durable and performing shower valve, it is important to choose the best shower valve brand that you can find. This is because a branded model will use quality materials in its build construction as well as provide you with a form of a warranty that you will never get if you choose to go with a no-name brand.

How to Install Shower Valve

How to Install Shower Valve

Installing the shower valve is not a very difficult task and it still remains quite big and a friendly. Here is a stepwise manner and how to install the shower valve in your bathroom.

Step 1 - Remove the Handle

Your shower valve should normally come with a handle. Remove that handle using either a screwdriver or an Allen-wrench so as to gain access to the innards of the shower valve. It is at this point that you should also shut down your water mains to prevent water from flowing during the installation.

Step 2 – Remove Trim Plate

You now need to gain access to the plumbing system behind the escutcheon trim plate of your shower. This plate should normally use a clicking system so you can open it by placing a flat head screwdriver between your wall and the escutcheon trim plate. However, there are some models that are secured with a bolt or an Allen-wrench. Use the appropriate tool to remove this trim plate.

Step 3 – Access Your Plumbing System

Once the escutcheon trim plate has been removed, you should now see the plumbing system. However, it may be too tight to work with comfortably so you need to create a hole large enough so you can gain access inside for the installation.

Step 4 – Connect the Shower Valve

Now that you have gained access to the plumbing system and water pipes, remove your old valve if you have one. If not, simply connect the new shower valve to the pipes using the appropriate fittings. Don’t forget to use plumbers tape on the threads of the shower valve so as to prevent any leaking. Additionally, you may want to replace any fittings if they are old to further prevent the possibility of leakage.

Step 5 – Let the Water Flow

Once you have made all the connections to the shower valve, open the water mains and see if there is any leakage. Let it flow for around 5 minutes just to make sure there are no leakages. Once done, place the escutcheon trim plate again on the wall and connect the handle to the shower valve. The shower valve is now installed and good to go.

Conclusion

As we have seen, the shower valve is an important shower accessory that will not only regulate the flow of water but also allow the shower to deliver the same water temperature every time you switch your shower on. Indeed, this is an important safety accessory that drastically reduces the risk of scalding during a shower.

Best, it is very easy to install and even if you have no plumbing experience, you will have absolutely no problem installing the shower valve.

Finally, our shower head review above provides you with a list of some quality and popular models. If you are still uncertain which shower valve to choose at this point, we recommend you read our review again.
