Buying Guide for the Best Shower Valve
For many people, taking a shower is a necessary part of their daily routine. However, if your shower isn’t working correctly, then it can throw off your whole day and create a host of problems that will only get worse. One overlooked component is a shower valve. This simple device can work in a variety of ways, but it’s imperative that you understand how it works and what it does so that you can be sure you’re getting the most value from yours.
Today we’re not only going to be looking at the shower valves, but we’ll dive into the various mechanisms and components involved so that you can make an informed decision. Whether your shower isn’t working or you’re looking to upgrade, the right shower valve can make a significant impact.
What is the Best Shower Valve?
Although these valves can be relatively complicated in some situations, the basic method of operation is this - the valve controls how the water flows from your pipe into the shower or bathtub. Some valves allow you to monitor and adjust the water pressure, while others may simply divert the water from the tub to the shower-head. In some instances, you may decide to get a valve that can do both, as well as control the water temperature.
Shower valves have to be installed behind the fixture and attached to the piping. Thus, you will likely want to seek professional help rather than doing it yourself. If you’re not sure what you’re doing, you could be looking at costly repairs, particularly if you don’t seal the pipes correctly before starting.
Overall, choosing the right shower valve can provide you with additional precision and control over the way you experience your shower. It can either be simplistic or complex, depending on your needs and your desires.

What makes this valve high-quality is that it comes with both anti-scalding and anti-freezing protection. Also, it will regulate the water pressure and shut off if your system is too low. That being said, if you have a low-flow shower, this valve may not work properly, so you will want to test it beforehand.

This way, you can divert water from the bathtub to the shower, and you can adjust the water pressure and the temperature separately.

It has a sleek chrome finish, and it makes it easy to tell when the water is cold or hot at any given time.

How to Choose the Best Shower Valve
First and foremost, you will want to figure out where you’re going to deploy your new valve. The reason that this should be your initial step is that it will dictate the kind of valve you will want to get, as well as the installation process that may be required. For example, if you’re installing a new valve in the kid’s bathroom, you may simply want something that allows them to switch between the bathtub and the showerhead without any additional controls. If it’s for the master bath, you may prefer to have the ability to adjust your shower experience as you see fit. If you’re not sure what you’re trying to achieve, then you will probably want to consult with a professional to see what options are out there and what you can expect from each one. As we continue looking at various components of shower valves, it should help you get a better understanding of the potential you may have at your disposal.
Type of Shower Valve
Once you’ve figured out where you’re going to install the valve, then the next step is to determine which model is right for your needs. Typically speaking, there are three options available, so let’s go over the various elements of each valve in more detail.
If water temperature is crucial for you, then you will want to invest in a thermostatic valve. These models can either be manual or automatic, depending on how much customization and personalization you want to achieve. Manual thermostatic valves usually have an internal mechanism (like wax) that will cut off the water flow if it gets too hot. For example, if you live in a house where the shower can get scalding if someone else is using a water source (i.e., the toilet), a thermostatic valve may help you avoid getting burned. Automatic versions will usually come with a personalized control panel. This will enable you to set the temperature to your desired preference and ensure that it doesn’t go above or below. Typically, the valve will adjust the water pressure and flow to meet demand so that you don’t have to do anything besides set the temperature you want.
This type of shower valve works the same way as a manual thermostatic model, except that it doesn’t shut off the water entirely if it gets too hot. Instead, it monitors and regulates the water pressure from both the cold and hot sources so that your temperature remains constant. Using our example from above, if someone did flush the toilet (thereby reducing the amount of cold water), the valve would reduce the hot water pressure so that you don’t get scalded. Overall, pressure balancing valves are the most common as they alleviate the issues presented by old plumbing systems and ensure consistent performance from your shower.
If you have a shower that’s attached to a bathtub, then you want to be able to choose one or the other. Without this kind of valve, you will have water spraying from both fixtures, which can be annoying as well as exceedingly wasteful. Diverter valves can only move the water in one direction. Thus, you can just use the shower or the tub. Also, if you have a two-in-one showerhead (i.e., one with a handheld unit), then a diverter will only enable you to use one head at a time. Transfer valves, however, allow you to utilize water from different sources. With a transfer valve, you can operate both showerheads simultaneously if you prefer. If that sounds like something you’re interested in, then you will want to get a combo diverter/transfer valve that can keep the bathtub off while enabling both heads.
Typically speaking, shower valves will have one, two, or three control mechanisms. Let’s look at how more of these components can impact the overall experience. One Control - usually, this will be a pressure-balancing valve as it will regulate the amount of hot and cold water, as well as the overall pressure. Two Controls - in this instance, the temperature is adjusted by one knob, and the water pressure is controlled by another. Three Controls - in some cases, you may be able to adjust hot and cold water individually (if they are coming from separate pipes). Otherwise, it will be the same as a two-control valve except you can also divert the water as needed. When looking at a multi-control shower valve, you will have to buy handles for each option. For example, one-control valves will need a single trim, and so on.
Who Needs the Best Shower Valve?
Overall, if you’re looking to upgrade your showering experience, it may be time to find a better shower valve that can enable you to adjust things like the water pressure and the temperature. Other reasons to get a new shower valve may be that your old one is leaking or that it doesn’t work as quickly as it used to. Because these components can break down over time, it’s imperative that you keep them up to date so that you can maximize their performance.
Because the Best shower valve is the one that offers the most control and reliability for your bathing experience, we believe that the best model on this list is the Kohler Pressure Balancing Valve. However, if you want a little more customization, then we highly suggest buying the SR Sun Rise Square. We prefer the latter model because it also comes with a trim, and the ceramic components are built to last. Regardless, both of these valves will offer incredible results and will keep your shower in pristine condition for years to come.
