3 Outlet Shower Valves
3 Outlet shower valves are a popular choice for a new shower. These shower valves are also known as a 'triple concealed shower valve' or often referred to as a '3 way shower valve'
A 3 outlet shower valve will control the flow and temperature of the water to three shower parts - for example a fixed rain head, slide rail kit and a overflow bath filler. The controls are often in a round or square design and allow full control of the water to whichever part. We also sell shower heads, slide rails kits and bath waste overflow fillers. If you are unsure which parts to order, contact us and we can help!

What Is a 3 Outlet Shower Valve?
A 3-outlet shower valve is a concealed thermostatic valve that directs water to three different outlets. It allows you to switch between them individually or, depending on the model, operate multiple outlets simultaneously.
These valves are installed behind the wall surface, with only the control plate and handles visible once fitted.
They are commonly used in:
-
Bathrooms with combined bath and shower setups
-
Walk-in showers with multiple shower heads
-
Design-led renovations requiring flexible water control
How Does a Triple Shower Valve Work?
A triple outlet shower valve contains:
-
A thermostatic cartridge to regulate temperature
-
A diverter mechanism to switch between outlets
-
Flow controls to adjust water volume
The diverter allows you to:
-
Select outlet one
-
Select outlet two
-
Select outlet three
-
In some cases, run two outlets together
Always check product specifications to confirm whether simultaneous outlet operation is supported.
Common 3 Outlet Configurations
3 outlet valves are often paired with:
Overhead Rainfall + Handset + Bath Filler
A popular configuration in family bathrooms where a bath and shower share the same system.
Rainfall Head + Handset + Body Jets
Used in larger walk-in shower designs where enhanced coverage is desired.
Ceiling Head + Wall Arm Head + Handset
Allows different shower experiences within one enclosure.
The flexibility of a 3-way shower valve makes it ideal for more advanced bathroom layouts.
Water Pressure & System Compatibility
Because a 3-outlet shower valve may supply multiple outlets, adequate water pressure is important.
Before purchasing, check:
-
Minimum bar pressure requirement
-
Compatibility with combi boilers
-
Suitability for pumped or gravity-fed systems
-
Flow rate capacity if planning simultaneous use
Rainfall heads and multiple outlets perform best in medium to high pressure systems.
If pressure is limited, operating outlets one at a time may provide better performance.
3 Outlet vs 2 Outlet Shower Valves
Understanding the difference helps avoid ordering the wrong configuration.
2 Outlet Shower Valve
Controls two outputs, typically rainfall head + handset.
3 Outlet Shower Valve
Controls three outputs, often adding a bath filler or additional shower head.
If your bathroom layout includes both bath and shower functionality controlled from one panel, a 3 outlet valve is typically required.
Concealed Installation Considerations
Triple shower valves are concealed systems and require:
-
Adequate wall cavity depth
-
Professional installation
-
Access for servicing where possible
-
Correct pipe planning before tiling
They are best suited to full renovations rather than simple shower replacements.
