I'm in the planning stage of remodelling my bathroom. I want to tile the
floor, and have been given enough tiles to do the job. The only slight
problem is that the tiles are 30cm a side, and I've been warned that if
the floor isn't 100% stable they'll be liable to crack.

And come loose.

The boards under the carpet are currently 60cm wide, not sure how long
as I haven't pulled up enough of the carpet to find out. I'm not sure
what the material is, but it doesn't look like wood. There is no
noticeable give in the floor, even when I jump on it.

Sounds like chipboard flooring panels.

Am I liable to have a problem? Should I just aim to position the tiles
so they meet over the joins in the boards, and use a felexible grout?

The normal recommendation is to fix 6mm plywood over the floor, screwed in
place, then use a flexible adhesive designed for the job.
