If you've chased into existing good plaster and are going to tile over
there's often no need to even make good the chase.

Except you reduce impact resistance and have that quality hollow sound

I don't do jobs at home with a view of selling. ;-) Not making good round
backing boxes etc when tiling allows you to move them slightly to get that
perfect alignment between tile runs. Which to me is more important.
