Single or twin outlet shower valve: one head or two
At a glance
- Running two outlets at once splits the available flow between them, so a supply that's marginal for one head can feel weak running two.
- A diverter valve lets you switch between outlets rather than running them together, which suits modest pressure while still giving a choice of head.
How to choose
Point 1
Running two outlets at once splits the available flow between them, so a supply that's marginal for one head can feel weak running two.
Point 2
A diverter valve lets you switch between outlets rather than running them together, which suits modest pressure while still giving a choice of head.
Point 3
Twin outlet valves need more pipework routed to the wall, which is worth deciding before the wall is boarded and tiled.
Where this fits with our work
Your questions answered
Do I need a pump for a twin outlet valve?
Only if the existing supply can't sustain adequate flow to both outlets, worth checking pressure and flow rate before specifying it.
Is a triple valve overkill for most bathrooms?
For a single-occupant or simple family bathroom, yes; it earns its keep more in a larger shower with body jets or a rainfall head plus handset.
Add single or twin outlet valve to a wider project?
Plenty of this work happens alongside other jobs in the house. Tell us the whole picture and the sequencing gets easier.
