Burying copper pipe in walls

[willow]

Reading these great pages, I am now aware that Potable pipe cannot be buried in walls. However, please can anyone advise whether it is ok to bury a pipe from a shower pump into a brick wall channel ?

If not then please can anyone advise how to box a copper pipe in brick walls and plaster over it ? Unfortunately it cannot be exposed as the shower head needs to attach to this.

Thanks
