Frequently Asked Questions
Why does standing around it help?
It gives the best users-per-connection ratio.
One waste, one supply, one spray assembly.
Serving four to eight people at once.
Against one tap and trap each otherwise.
The saving is in plumbing, not fixtures.
Where does that matter most?
Wherever everybody washes at once.
Factories at shift change.
Schools between lessons.
Stadiums at half-time.
And entries to food production areas.
How is it faster than a row of basins?
Nobody queues behind a particular tap.
Any free segment can be used.
So the whole fixture stays occupied.
A row of basins has idle taps and queues.
The throughput difference is large.
What does it need from the room?
Clear floor on every side.
It cannot stand against a wall.
Approach from all round is the point.
Allow the working zone in the layout.
Not just the fixture diameter.
Where do the services come from?
Up through the floor, not the wall.
It stands in the middle of the room.
So supply and waste rise into its base.
In a refurbishment that is the constraint.
Coring an existing slab is real work.
Why foot or knee operation?
So hands never touch the control.
Which is the point of washing them.
It removes the tap as a dirty surface.
And it stops water being left running.
Specify it rather than assuming it.
How is the diameter chosen?
By how many must wash at once.
Each user needs an arc of the rim.
More users means a bigger circle.
And a bigger clear zone around it.
Size the room, not just the bowl.
