Chasing pipes for shower

[smudger]

I'm refitting a bathroom and the client wants the shower on the opposite wall. I want to hide the pipes behind the tiling, but the plaster/render is not thick enough to take pipe and sleeving (overflow pipe) and I'm worried that if I chase into brickwork it will either weaken wall or remove plaster on other side. My other option is to build false wall the width of the bath and cover pipes in this way. What do other more experienced guys do?
Thanks in anticipation.😕

Thanks Gray. What's the best lagging for this, normal foam lagging or felt type?😕 I haven't done my water regs yet (got them next month) but I understood that you had to enclose buried pipes in plastic so that they can be removed/repaired without damaging wall. Hence I was intending to sheath in pverflow pipe.

9mm foam lagging
Forget about that bit about pipes should be accessable even it you have in overflow pipe how do you get it out again?
