What pipework to supply *two* power showers?

What is the recommended pipework arrangement to supply *two* power showers from the same HWC and cold tank? (They will be the on-the-wall integrated pump type - not a separate impeller pump)

I understand the need to use a surrey/ york flange to provide a reliable how water feed; similarly, a new separate cold water pipe run from the storage tank for the first shower. Can I just tee off those pipes for the second shower?

If I need to provide completely separate pipe runs, how do I get two separate hot supplies from the surrey/ york flange?

Thanks

Its a bit naughty to call them power showers!

They are just a way to overcome poor head supplies.

The flow rate is usually no more than 10 li/min at best.

Whatever we call them ('integral pump assisted showers' perhaps?) my purpose is exactly what you said - to get a moderate boost to the poor flow I currently have due to a limited supply head.

I'm looking at a Mira model that says it will boost to (up to) 16 litres per minute, which would be more than adequate - I'm not looking for ultimate drenching power!

..... and I still need to find out how to plumb in *two* of them.

EH? An Aquastream's 18l/min

Proper answer is two separate supplies, so eg an Essex flange. But you might get away with splitting one.

Essex flange costs a few quid and takes 5 minures to fit (once you've drained some water out!)
