Hiding waste water pipe inside my bathroom wall

Why not just box it in, and place a narrow shelf on top of the boxing? Personally I wouldn't cut it into the wall.

It will probably remain standing, but I wouldn't do it.

Why not drop it down and run it along the floor then hide it with one of those fat skirting boards designed to hide pipes?

It was boxed in until recently but, as there's a small radiator on that wall too, the boxing looked untidy and came too near to the bottom of the rad (restricting airflow).

I am trying to avoid tiling over an untidy looking boxed-in wastepipe.

I've just found the Celcon website, which advises maximum chase depth horizontally to no more than 1/6 block thickness. Is there an easy way to check block thickness? Perhaps it's more than 100mm--maybe a narrower waste pipe is available?

It is very unlikely to be more than 100mm. 100mm is by far the most common size and is easily strong enough for a single storey outhouse wall.

I would go for the boxing in too, box down to the floor and have a nice tiled shelf for pretty toiletries and pot-pourrie, er a stack of screwfix catalogues and some beers.

Why not lift the radiator slightly so it's off the boxing by an appropriate amount.
