Diverters for a bath, overhead shower & hand shower

[Possom]

In the bathroom the water outlets will consist of
a) hand-shower,
b) ceiling-hung overhead shower,
c) bath taps

as well as toilet and a basin.

I want the overhead and hand showers to be thermostatic, so is it a 2-way diverter thermostatic trim (either of first two pics) plus a concealed thermostatic shower mixer which would be required?

Would any other diverters/levers be required? Or is it a 3-way diverter which is required?

Thanks.

You will not require a diverter for toilet or hand basin.
With regards to shower rose, hand held shower and bath filler, that would depend on what you want to achieve?
Some showers control valves are integrated to divert rose and hand held shower heads. But if you are having a bath mounted hand held shower you can divert that with the bath filler, if required, it can be excluded.
So depends what set up you are after.

There will be one ceiling mounted shower over the bath. One hand-held shower on the wall, and one mixer bath inlet.

I'm not sure about this in all honesty. Anyone have any suggestions on what setup is the best way to go?
