If the floor is not very flat, then you need a wider joint to help compensate. Expansion is not the issue at all.
3/16" joints are common for that size tile.

I have tiled most of my bathroom now (half way up the walls) with NO grout line. Was this a mistake ?? I am a little worried. I did this because I did not want the maintenance of dirty grout lines in the shower. I did not know about an expansion factor.

Are my new tiles going to crack as some have mentioned ? My house is a single story house on a cement slab (if that matters any).

Please help put my worries to rest.
