Thanks for the replies so far. I will have a go at scribing and using a small chisel.
No Gooner it is not a shared passage otherwise I would probably have done as you suggest. I might even have just tiled my half :lol:.
I have just started taking the old tiles up and they are all coming up perfectly clean so I will use a few of them to practice on and then reuse to good ones. They are fortunately the same as the new ones I am getting.
I forgot till the Mrs reminded me a few minutes ago:mad2: I have a manual cutter I bought years ago to do my bathroom. Will dig it out and have a go with that but I think the tiles will be too hard for that.
If it turns out ok I might even post some pics. If not I'll put a rug over it.....:lol:
