 Factors to Consider When Buying the Best Thermostatic Shower Valve 

Different types of shower valves

You will notice that there are three types of shower valves to choose from. It is important to know the types when you are shopping to ensure you purchase the right shower valve for your needs.

  • Pressure balancing – Overcoming pressure fluctuations, pressure-balancing valves provide a consistent temperature of your shower water.
  • Thermostatic – Mixes cold and hot water to create your preferred temperature consistently throughout your shower.
  • Volume control – Volume control valves control the amount of water that goes to the shower using single or dual-handle valves.

Pressure Balancing:

By balancing the water pressure from sudden uses by other water sources, pressure-balancing valves will adjust the cold and hot temperature for you.

The mechanism inside is designed to balance the pressure and not adjust the temperature directly.

Thermostatic Shower Valves:

The Thermostatic shower valve can control the pressure and temperature as needed. You set the temperature before you turn the showerhead on, so you won’t have to wait for your water to heat up or cool down.

Preventing uneven temperature fluctuations, this valve is designed to make showering more comfortable.

A thermostatic shower valve will also come with a volume control technology that controls the shower’s water flow amount. Some of these valves come with a digital panel, so you don’t have to use a metal handle.

These panels can also offer more features like timers and a water conservation function.

Volume Control

Controlling the amount of water, a volume control valve uses either a single or dual handle valve.

Single-handle Valve – Providing the easiest way to reach the preferred temperature, a single-handle valve combines hot and cold water in central control.

With a single handle, you turn it either right or left to either increase or decrease the temperature. As the handle is turned, it ensures that the water flowing through the tubes increases and pushes the temperature in the mix to either warmer or cooler.

 How does a shower valve work? 

At first, the shower valve will store water at a high temperature, killing most of the bacteria found in it. Then, the hot and cold water will mix to reach the set temperature so it is correct when it comes out.

Thermostatic vs Pressure Balance

Invented to control the temperature ratio, a pressure-balancing shower valve mixes cold and hot water. It contains a pressure-balancing spool that will adjust the ratio as the cold water draws to a separate fixture.

This is an efficient and cost-effective option for a shower, but keep in mind that sudden temperature fluctuations can happen using this valve, so it is not suggested for elderly individuals.

With a thermostatic shower valve, you have a mechanism that will work consistently to make adjustments in the event of a sudden water pressure change.

This allows you to have your preferred temperature consistently throughout your shower. It also gives you a great water flow rate in comparison to pressure balance valves.

A thermostatic shower valve is also a great choice if you have a modern shower panel that comes with the sprays. If you have a modern shower panel with jet sprays, then you should consider a shower valve that comes with the best flow rates.

These are more expensive than other types of valves, but they are a good way of ensuring that you get the right temperature for safety reasons.

What type of shower valve do I have?

The best way to determine what shower valve you currently have is to understand how all the different types work. Since all the valves work differently, you need to focus on how they work to figure out which of the shower valves you have.


When choosing a new shower valve, it is important to determine which will be the best thermostatic shower valve for your needs.

Remember that since it will affect the performance of your shower, a shower valve will have a huge impact on your shower experience as well as improve the quality of the plumbing system.
