Fitting a concealed shower valve and concealed shower kit

[lummac]

Wife bought for our new bathroom a concealed shower valve and a singel function shower kit from Bathstore - all of the concealed pipework type

Are there any special fitting kits for these, or is it (for me) cuttig a hole in the brick wall as to where the shower valve goes and chassing the wall for the pipes,

also for the shower kit as this also needs to be plumbed in - within the wall that is, do you us a 1/2 wall plate for that

Thanks
Chris
