Power Shower Installation

[chop_chop]

I've been asked to install a Power Shower above a friends existing bath (they currently have a mixer shower attachment). I've had a look at the hot water cylinder and they already have a power shower supplying a seperate ensuite shower cubicle. What do I need to identify in order to check the system is compatible and how easy is it going to be to install using exisiting or new pipework.

if it's a decent shower pump (3 bar?) then you mat be able to tee off the existing feeds to the ensuite and run both showers from a single pump.

Regarding the pipework - it depends on the location of the proposed shower
