The valve is considered as the most important element integrated in the shower today. Apparent, most of the advancements in shower are located in the shower valves. Currently, there are two types: pressure balanced valve or thermostatic shower valve, both of which eliminate temperature shifts in the shower. However, is one more preferable than the other?

Pressure Balance Shower Valve
From the outside, the pressure balance shower valve looks like any other valves. The big difference is found inside, it has a piston mechanism. This mechanism balances out the hot and cold water in order to produce desirable water temperature. Typically, it keeps the temperature constant by reducing water flow.
The problem with these is the water flow. They are not ideal for high water flow hence, they are not expected to be able to replace thermostatic temperature control valve. Kohler HiFlow Rite Temp Single Control Pressure Balancing Valve is a great example of innovative custom showering valves. This valve shuts off automatically if the supply of cold water is disrupted.
Thermostatic Temperature Control Valve
For most residence, water flow and volume control are essential. In this situation, the thermostatic shower valves are always the better choice. They frequently have 3/4 inch inlets that are able to produce high water flow through multiple showerheads. They allow user to sustain a set temperature when it is either off or on. A good example of a thermostatic valve is the Grohtherm High Flow 3/4inch Thermostat Valve. This is perfect for large multiple head custom shower systems. It however, requires a separate volume control. The disadvantage of all thermostatic temperature control valves over pressure balance shower valves is their price. This type of low flow shower head can run up to $1,000.
