Best Thermostatic Shower Valve Buying Guide
The only way to shop for the best thermostatic shower valves is by checking a list of essential factors that can influence the performance of the valve. Here are some critical things you should know about a thermostatic shower valve before placing your order.
What are the Different Types of Shower Valves?
There are multiple types of shower valves available in the market, and a thermostatic shower valve is one of them. Check out these other types of valves for better knowledge.
1. Diverter Valves
Diverter valves are ideal for directing the flow of water to various areas in the bathroom, including the bathtub and the showerhead. There is a single control handle available, and you can rotate it on either side to get the water flowing through different faucets.
2. Transfer Valves
A transfer valve is perfect if you want the water to flow through multiple outlets simultaneously, including showerhead, handheld wand, and through tap. Transfer valves are a bit expensive because of their versatility and build-quality.
3. Thermostatic Valves
Thermostatic shower valves can maintain both the flow and temperature of the water. These shower valves contain a thermostatic element that is responsible for adjusting the flow of hot and cold water. There is a control dial available with thermostatic shower valves, and you can use it to adjust the temperature of the water.
You can even choose a thermostatic valve that allows adjusting the volume of water coming out of the showerhead.
4. Mixing Valves
A mixing valve is what you will find in old homes. These valves have two ends connected with a hot and cold water supply. With a mixing valve, you have to rotate the knob to get an ideal water temperature for bathing.
However, the downside of the mixing valve is that the temperature of the water can change suddenly. Also, the pressure doesn’t remain steady, so you have to struggle with the knob to maintain the temperature of the water.
5. Pressure Balancing Valve
A pressure balancing shower valve or mechanical valve is the most common type found in homes. With this shower valve, you will get the right balance of water, which is neither too cold nor too hot. The valve contains a piston-like thermostatic valve that adjusts the flow and temperature of the water.
Generally, pressure-balancing valves come with a single control handle, and you can use it to regulate the temperature of the water.
Thermostatic vs. Pressure Balance Valve
When I first heard of a pressure balance valve, I thought that it was another name for the thermostatic valve because of the presence of the piston. But there are some significant differences that make thermostatic and pressure balance valves different.
With a thermostatic shower valve, you will get two knobs or handles destined to regulate the flow and temperature of the water. You can adjust the flow of water while keeping the temperature constant, and it is one of the biggest advantages of thermostatic valves over pressure balance valves.
On the other hand, there is only one control handle available with pressure balance valves. You can use the handle to adjust the temperature and pressure, so it becomes hectic to maintain the right balance of temperature and pressure.
In short, a thermostatic shower valve makes it easier to set an ideal temperature without affecting the flow of water.
Thermostatic shower valves are perfect for saving gallons of water every day. You can reduce the flow of water while shaving or shampooing, so there will be less wastage of water. But this is not the case with pressure balance valves.
A lot of water gets squandered, so you have to pay more on your water bills with a pressure valve as compared to a thermostatic valve.
Scalding is a common problem with a pressure balance valve, and if you are using one, then you cannot agree more with this statement. Thermostatic shower valves come equipped with advanced scald formation, so you will never face a steamy hot shower again in your life.
Overall, a thermostatic shower valve turns out to be a better option as compared with a pressure balance valve. However, pressure balance valves are initially cheaper. But when you see it in the long run, then a thermostatic valve is a good option to go with.
What are the Benefits of Thermostatic Shower Valves?
The benefits offered by a thermostatic shower valve were enough to convince me to get one installed in my bathroom. Here are the benefits you will get by switching to a thermostatic valve.

With a regular mixer valve, there is a possibility of scalding, as these valves don’t keep the water temperature constant. And steamy hot water can lead to a lot of skin and hair troubles, along with causing burning sensations.
With a thermostatic valve, the temperature of the water will remain steady, so there will be no issues of scalding.
2. Ease of Installation
Thermostatic shower valves like Delta R10000-UNBXHF are easy to install. There is no need to schedule a plumber to install it for you when you can do it on your own. In short, you can save some more money with a thermostatic shower valve by opting for DIY installation.
3. Ultimate Convenience
Thermostatic shower valves come with two knobs, one for regulating temperature and one for pressure. You can use the knobs based on your convenience.
Whether you need hot water with less flow, or more pressure without raising the temperature, you can do it right with a thermostatic shower valve.
Also, you can keep the temperature knob set while turning off the pressure of water, so there is no need to set the ideal temperature every day, as it is already set for you.
Installing a thermostatic shower valve is beneficial for your pocket too! You can reduce the flow of water anytime when required. As a result, you can conserve gallons of water every day.
Just rotate the knob to limit the flow of water, and you will see a significant difference in your water bills after installing a thermostatic shower valve.
