MOEN 2510 Posi-Temp(R) Shower ValveEditor's Choice

Features
  • Material: Metal
  • Number Off Ports: Four
  • Connecting Size: 1/2-inch
  • Instructions: Comes with installation manual
  • More features: Brass construction, temperature controls, delivers generous water flow

If you remember those sudden changes in shower water temperature and find yourself shuddering, then this shower valve will really be your savior. This particular company has a patented system installed in their shower valves, which is called a Posi Temp valve.

What this does is regulate the temperature of the water running. Once a temperature adjustment has been fed into the system, the valve will hold on to the reading, and prevent any warming up or cooling down of the water.

It uses a temperature-sensitive mechanism to hold the temperature within fluctuations of just about 2 degrees in Fahrenheit. The window for fluctuation is so small that you won’t even notice it standing below the shower.

Another thing that will come of great use to you is the flexibility in the design of faucets that are compatible with this valve. Many valves have to be adjusted when you change the faucet. But not with this one.

This valve has a common pairing system that will work well with any type of faucet or fixture you want from the market.

One added benefit of this is that you are never going to have to call a plumber to get your shower changed again. It’s very simple to thread in the new faucet yourself when the valve is as adjustable as this.

This valve requires pipes that are about ½ inches in thickness. And this is the most common thickness that internal piping has in most houses, so you won’t have to do any extra hassle over this anyway.

Thankfully, the valve is made from a non-metal element that doesn’t rust. It has stainless steel as an ingredient as well. So, you can expect this valve to last you a long time without any trouble.

Pros
  • Has a brass body that resists corrosion
  • Keeps temperature fluctuations within 2 degrees
  • Requires pipes of the regular thickness of ½ inches
  • Compatible with a variety of faucets and other fixtures
  • The strength of the stainless steel makes it last a long time
Cons
  • Check for all the screws as some might be missing in the kit

In the case of adapters, you can choose anything from copper, iron, PEX, and CPVC to make the connections airtight and sturdy.

On top of all this, it comes with a plaster guard, which will snap into place by 90 degrees in any place on the wall. This feature makes it super easy for the valve to snap into place, and for anyone to change the fixtures even without having any sort of training to do so.

There is a pressure cap in the lower part of the fixture, which will allow you to get super easy access to the flushing system. Yes, there is a built-in flushing mechanism in the valve, which will prevent hard water from getting deposited in the pipes. Thus, the faucet will remain shining and good as new for longer.

And the most important thing is that, with this valve, you will not only be able to control the temperature of the water, but also the pressure at which the water comes out from the faucet.

Pros
  • Super easy to work with
  • You can choose any type of adapter you want
  • Comes with a plaster guard for easy placement
  • Can be used to control both the temperature and the pressure of water

Features
  • Size: Single

  • Item Weight: 3.52 ounces

Kohler products always have the most elegant look. They are known for their sleekness in appearance and also in quality. When this shower valve is installed in your bathroom, a whole range of gorgeous Kohler plumbing fixtures will be available for you to beautify your space.

So, when we say that you are going to love this fixture, you cannot disagree with us. It comes with the most effortless temperature-sensitive system. When you feed a number to the system, it will always stay constant there.

You won’t have to face any sort of sudden changes in the temperature. The valve system will monitor the temperature and prevent fluctuations.

Also, the kit has everything that you will need to complete the setup. It comes with aerators to keep the water flow out uniformly, a faucet, adapters, and other accessories required to keep the shower running.

The system weighs only about 3.52 ounces and will stick to the walls without weighing down the surrounding plumbing systems.

Another thing is that the system is very simple. You just have to follow some instructions in order to set this up all by yourself.

The temperature can be handled quite perfectly by this device, but it takes no control of the water pressure. Therefore, if you are looking for something that can do both for you, then this valve is not for you.

Pros
  • Can control temperature without fluctuations
  • Compatible with other elegant Kohler faucets
  • Comes with all the attachments required to complete the setup
  • Has a uniform weight that doesn’t pull the plumbing system down

  • Finish: Chrome
  • Color: Polished Chrome
  • Item Weight: 7.8 ounces
  • Product Dimensions: 2.64 x 1.77 x 2.64 Inch
  • Water Flow: No limits on water flow

Having this beautiful brass valve system will really be of a lot of convenience for you when you realize that this allows for the water to be diverted between a hand shower and a regular shower head.

It can do that by the grace of having one inlet that is fed by two different outlets. All three of them are of the same measure – G 1//2 inches. This is the universal thickness for fixtures and is used to ensure that they can be threaded into all types of connections and fixtures in different houses.

The other thing that you will be sure to notice is the appearance of the valve. It does not look like any of the other ones we have discussed above. Its body has a sleek and shiny construction, made entirely of solid brass metal. It resists corrosion and any signs of wear and tear.

Due to the brass on the body, this valve has an amazing capability of retaining the temperature at a constant level. It is built very sturdily, and won’t wear out with time. Overall, it is a reliable valve that will have your back for many years.

The flow of water will be constant – there is no curbing inside. As a result, the water flows in a steady abundance. You will never have to struggle with the water not rising up to the tap when you have this valve.

So, not only does it keep the temperature fixed, but it also regulates water pressure to enhance the user experience.

This valve will sit on the outside of the wall, and thus it can be used just by turning the handle. There is a lever that has to be turned to convert the water temperature from hot to cold.

Installation is super easy as well. All you need is a swivel nut to get the valve into its place. Then work with it, and you will be done.

Pros
  • Very easy to operate
  • Installation is super simple
  • Can divert the flow of water from the shower head to the tub
  • The whole body is made of brass metal which is resistant to moisture

  • Material: Metal
  • Weight: 8.4 ounces
  • Size: 15/16" x 15/16" x 1/2"
  • Convert : 3 way
  • Operation: Smooth and reliable

With this valve, you have less flexibility in options. This is compatible with only a specific set of bidets, so you really have to check the box and the labels to see whether this will work with your system.

When you do not have any use for running water, you can turn this valve off by simply using the lever. It will help the system to last longer and keep its functions working smoothly.

The handle that is used to turn off the valve can also be used to adjust the pressure at which water comes out of the pipelines. So, not only will it help you control the temperature like most valves, it will give you added control so that you can really customize the shower experience to meet your preference.

Many valves can easily be turned on by children. Not this one, though. It comes with a locking mechanism that can be switched on whenever there is no use for the water. It will keep the valve safe from the children as well.

This valve will work with adapters that have a ballcock thread of 7/8 inches in thickness. So again, make sure that you have the right threading measures in the fixture because if they don’t match, there will be leaks from the valves.

Last but not least, you will be really impressed with the exterior of this valve. There are two outlets and an inlet, which can be used to easily divert the direction of the water.

Moreover, the design is very elegant – it has a nicely polished brass body, which is so graceful in appearance that it will brighten up the interior of the whole bathroom itself.

Pros
  • Reliable and easy to operate
  • Very beautiful chrome-plated fixture
  • You can turn this on/off whenever it’s not in use
  • Allows you to adjust the pressure along with the temperature
Cons
  • The threading does not get airtight and therefore the pipes leak
Features
  • Color: Multi
  • Material: Metal
  • Model : 2570
  • Finish Type: Unfinished
  • Connection: Four ports
  • Temperature: Adjustable

This is another shower valve that will help you with nothing but the temperature adjustment. So often it happens that these valves promise a lot, but do the minimal. Not with this one though.

The company believes in quality over quantity. So, even if there are not so many features here, you will still find yourself satisfied with the valve because it’s really good at doing what it promises to do.

And what this promises is the most satisfactory showering experience, which it will provide by controlling the temperature of water in the face of the most challenging conditions. Even if it is blazing hot outside, this valve will be able to bring down the temperature of the water and keep you happy.

The power to do this comes from the rock-solid construction of this system. It is made completely of brass, which is a mixed metal alloy that has all the properties required to give you the most long-lasting and well-functioning machine.

Brass makes this valve wear-resistant, a good conductor, and gives it incredible strength, among other benefits.

Another thing that will make you happy is the flexibility that you will have in changing the look of your bathroom. This valve is a 4 port-system. Meaning that it is a diverter, a great adapter, and also a connector all at once.

You won’t need to get any extra attachments to have this sit well with your plumbing system. As a result, the installation is easy. You will be able to do it all by yourself. Anytime you want to change the look of your bathroom, you will be able to unthread the faucet and pull a new one into the ½- inch connection port all by yourself.

Grohe 35015000 Grohsafe Shower ValveMost Efficient

Features
  • Manufacturer: Grohe
  • Material: Metal
  • Operation: Smooth
  • Weight: 3.15 pounds
  • Size: 7.48 x 6.50 x 6.30 inches

This is a shower valve that is completely gold in color. It will not show, of course, because it requires an in-wall installation. But you should know that this gold color comes from the use of the brass, which is an element that is best suited for this purpose.

Brass is a mixture of copper and zinc – the properties of these two metals come together to make this a rust-free and wear-resistant element. Even if there are leaks through the wall, this valve system will remain intact and adhere to its duty.

Being a cartridge valve, it will be able to handle all sorts of pressure controls and manage the flow of water through the shower head. This is, of course, only an addition to the temperature-sensitive feature of the valve.

The main purpose of this valve is to make sure that the water temperature does not fluctuate. This makes it really safe for you to have control over your showering experience. If you have kids, they will benefit greatly from this temperature-monitoring device.

Other than that, you will also find that there are stop valves in this system. They will let you cut off the water supply whenever you want. This will prevent the pipes from getting worn out due to the building pressure of water inside.

Last but not least, Grohe is a prestigious company with plumbing fixtures of many types and styles. All of those fixtures will be compatible with this valve system, and this is a great bonus because it means that you can change the look of your bathroom whenever you want.

And due to the easy installation of the pipes, you won’t even have to call a plumber for that – you can do it all by yourself by following the simple guidelines.

Pros
  • Makes it safe for the kids to take a shower on their own
  • Compatible with the whole range of Grohe plumbing fixtures
  • The kit comes with everything that is required for installation

  • Size : 0.5
  • Build Material: Metal
  • Manufacturer: Moen
  • Connection Size: 1/2-inch

This one from Moen looks different and has a bunch of features that the previously discussed one doesn’t. For one, it has a temperature control limit. So, not only will it hold on to the temperature adjustment fed into the system momentarily, but it will also prevent accidental increases in temperature.

The feature will particularly help if you have children – they might accidentally turn the knob and set up the faucet to spew out incredibly hot water. But that wouldn’t be the case here, as the control system will not let the water heat up beyond the set limit.

There is a common valve system, which is compatible with the pipes and fittings in most houses. All the connections are ½-inches in size to aim for universality.

Because of this universal feature, you will also be able to install any type of plumbing fixture you want. This makes it very convenient for people who would like to change the look of their bathroom without getting involved in all the plumbing details.

And as time goes, you will see that this valve does not give way to any sort of damage. All the functions will work properly, but you could give it the occasional clean up once in a while to keep the system working for a prolonged period.

Clean up is very easy – you will notice that there are stoppage points at every turn of the valve. These stoppage sites can be used to cut off the flow of water and flush out any grime building up inside due to the presence of hard water.

Pros
  • Has a temperature limiter
  • Elegant-looking and easy to install
  • Controls temperature very accurately
  • Compatible with a range of different fixtures
  • Clean up is made easy by the stoppage points at every quarter

Features
  • Size: Single
  • Color: Black

The cap is not a regular one made of brass, but it has a special advanced mechanism that fits flawlessly into any fixture and makes the water flow out in smooth progression.

It is easy to install, easy to work, and it will last you a long time without wearing out. Then there is the cartridge unit, which allows the water pressure to be maintained. There are 4 ports in the cycle of this unit, and they will allow you to make clear junctions into the plumbing system.

This cartridge will balance the temperature, and it will help to maintain it at that level no matter how harsh the weather condition is.

One drawback of this system is that it is unfortunately not compatible with all faucets, but will only work with two particular models, which are, K-11748 and K-304. So, if you do not have these shower trims, then this will not be the right suit for your use.

If you do have compatible units, then this will last you a long time. Because it has the most recent temperature-sensitive technology, which allows it to resist the corrosion caused by the presence of hard water in the supply.

  • Maintains steady water pressure
  • Prevents temperature fluctuations

How to Find Best Shower Valves - Buying Guide

Take your time when choosing the best shower valve set because it is an investment that is supposed to last you a long time. Here are some of the factors that you should consider carefully before purchasing.

Control Levels

Control levels are very important in case of shower valves because this is what you will use to choose the temperature and the pressure setting of your choice. There are three types of shower valve systems based on these control levels.

Single Control: The systems that come with a single control will start with regular temperature water, and then it will either cool down the water or heat it up depending on the setting you have fed into the system. Once the desired temperature has been achieved, the system will be done with its work. After that, it will hold on to that level until you turn it off.

Double Controls: This is the same as the single control one. But it gives you the option to control the water pressure as well. One control switch is for the temperature adjustment, and the other is for the pressure adjustment.

Triple Controls: Now, this one has three controls. One is for the temperature, the second is for the pressure, and the third one is for outlet selection. This system has to be used with more fancy trim kits that have multiple outlets.

All the outlets will be connected through this one valve system. And then you can use the third control to determine the outlet you want the water to come out from.

Types of System

There are two different types – one is thermostatic, and the other is plain manual. With the thermostatic one, you will be able to leave the system to do its thing. It will automatically cut off the water supply when your desired temperature and water pressure starts to fluctuate beyond a certain limit.

And with the manual one, you will have to turn the system on/off by sensing the temperature yourself.

Types of Shower Valves

There are four main types of shower valves. These are –

1. Pressure-Controlling or Mechanical Valves

These valves can detect a difference in the pressure value on their own and make changes to adjust the temperature to a certain level.

If two taps are opened at the same time, then there will be a change in the pressure. It will use that discrepancy to adjust the temperature automatically.

2. Thermostatic Shower Valves

You have to feed the value of your desired temperature in the system. Then, it will adjust both the temperature and the pressure based on that. This is more precise and comfortable to use, but it is also a bit more costly than the mechanical one as well.

3. Diverting Shower Valves

These allow different water taps to be joined in conjunction. They are shaped like the letter T, and there is a small lever on top. You have to pull this lever to shift the flow of water from one tap to the other.

Shower Valve Installation (Things You Need to Know)

We are not going to provide you the whole step-by-step guide in this best shower valve review as you will be able to find those in abundance on the internet. But we will give you some pointers so that you don’t get confused while installing it yourself.

To begin, you will need all the necessary tools. Apart from the valve and the cap, you will need tape, lube, a faucet or shower head, and some tubes.

Some of these things will be included in the kit, but you will have to purchase the others. The whole set up is very simple if you follow guidelines.

In most cases, the tube is not provided. So, you will have to buy it. In this case, the PEX tubing will be well worth your money and your time because it is a good conducting connector, and it can resist high temperatures. You will be able to connect it directly to the tanking system.

And when starting the installation, begin with the faucet in order to prevent the water from spewing out everywhere when the connections have been made.

FAQ's

Q: Is it necessary to install a shower valve? 

Ans: Yes, they will prevent sudden steep fluctuations in water temperature to give you a more satisfying showering experience.

Q: Will these valves filter out hard water?

Ans: Only to a little extent. You mostly have to deal with the hard water manually.

Q: What happens if the tank runs out of cold-water supply?

Ans: The valve will cut off the flow of water entirely.

Q: Is it important to shower with water at an even temperature?

Ans: Yes, showering with water of even temperatures is recommended for good health.
