Shower Valve/Diverter Recommendation

[kheflw]

Hi all, I'm overwhelmed with all the information needed to buy a shower valve. Been searching all my usual places and not finding what I want. I'm sure it's a simple probably standard thing, so I'm asking for your help top point me to a a couple of products that will fit the need.

I want a 3 piece spray system.
1 - Standard Fixed Shower Head
2 - Rain Head - This will be mounted to the Ceiling, straight pipe
3- Spray Bar Head -

Also, the mixing valve will be on one wall, and the diverter valve will be on an adjacent wall - This is so I can reach in to turn on the water without getting wet. Diverter valve will be in line with the Fixed Shower Head.

I know very little about Thermostatically Controlled or Pressure Balance. The former seems like something I might want.

For the Diverter -
I want to control the Fixed Head by itself.
The Rain Head by itself.
Both Fixed and Rain at the same time.
Spray Bar by itself.

So it seems I need a 4 position Diverter, or is there a better solution that you might suggest?

Thank you - PS - I really have been trying to find this info on my own, just not coming up with anything.

Thanks
