I've recently had some showers fitted and I didn't specify that the
pipes should be chased into the walls. I need to find a solution, and
recognise my own mistake so I will be paying for it.

The contractor says that as the walls that the showers are mounted on
are single skin "breeze blocks" (100mm) its not possible to chase 22mm
pipes into the wall because it will damage the structural integrity of
the blocks - and that building regs prevent it.

Is this the case?

If he won't do it, I'm prepared to get the angle grinder out myself.

Thanks in advance for any help!
