Routing mixer shower pipes in the wall

Hello everyone, 1st post! My partner and I have just moved into our 1st house and being potless want to do as much as possible, unfortunatley wood is my medium not plumbinig! It's just a quick question about mixer showers. My other half has found this : Triton Excellente Bar Diverter Electric Shower Black, 5012663016293 the Triton Excellente Bar Diverter.

The question is basically mounting. I have the water bit nailed it's just the pipes. Do I have to remove a large amount or wall (solid brick on each side of the bathroom - old house) or is there some kind of mount/false wall I can fit and tile as opposed to bashing around my whole bathroom. It just seems like a hell of alot of work if I have to remove loads or bricks and plaster over....

If I have confused people with the post I am sorry, I am a new to this and hope the answers will save us some money if not a little time! Luckly all the pipes/shut off valves etc... are open around the room. Don't think they cared that much when putting everything in initially. Oh, there's no shower at the moment, bath only....

Any help VERY welcome

Have a look at the technical specs on the Trito website. Usually have all the info on there.

just need to chase the wall for the services if its going over the bath i probably only means a couple of foot of chasing hardly major works

You say you want save money by doing your own works,then looking for short cuts as maybe to much work to do,,love it
Get stuck in and chase out wall for pipework as required,as said,will not take long,just long enough exercise to get rid of that big christmas dinner
