I live in an old house with floorboards that are pretty uneven.

For the small bathroom (1.7 x 2.12m) bathroom I want to lay ceramic
floor tiles but am concerned that they may look unsightly on the
uneven surface, and maybe even crack when they are stood on.

I don't really want to lay a thick false floor underneath as it will
make a 'step' into the room. Can anyone advise on the options
available to me please.
