Is there an alternative to using plastic/chrome trims on external corners when using marble tiles on a bathroom wall? Presumably mitring might result in the tiles cracking. They are about 10mm thick, polished on the surface, but not on the edges, so would look ugly butted together. Is there a way of polishing the edges perhaps? Or are marble trims available?

I was on holiday last week in a holiday cottage, one of those second home places that are rented out for a few weeks during the year so some of them have been renovated to quite a high standard.

Now, sitting on the toilet I happened to notice - as you do when you look around other people's toilets - that the tiling had been done very well indeed and one particular aspect of it had been done in a way I have never seen before... the external corners had been MITRED, cut away on the corner to within a mil of the glazed edge, giving a sharp, close-fitting edge.

As I said, never seen it before and would never have dreamt of doing it. It was either the result of someone doing a bit of lateral thinking of their own or someone having been told about the technique by one of those clever sods we all hate because they have all the good ideas first.

Of course, with the introduction of some pretty effective powered tile cutters nowadays with diamond blades that can be set to 45 degrees, the use of such techniques is suddenly possible.

It might just be the answer to your question. If it works, let us all know!
