I propose laying ceramic floor tiles in a downstairs toilet. My initial plan
was to cut the tiles around the pan, but someone has suggested that it would
be better to remove the pan; lay the tiles and refit the pan on top of the
tiles.

There is a fair amount of fiddling about in both options, but which is best?
I am concerned about drilling holes in the tiles to secure the pan if it
goes on top of the tiles; and would the fixing screws be long enough?

Any thoughts welcome!!
