Tile floor in bathroom

I'm getting ready to install a tile floor in the bathroom with 12" X 12" tiles.
What grout spacing is ideal for this?
What mortar trowel (groove spacing and depth) should be used?

The dimensions of the room are: 5.5' X 6.5' so it's not real big of an area.

It will be over a slab foundation if that helps at all.

There is one small crack in the floor, of course right in the middle of the floor.
Should I try and do anything with this?
(this is of course a close up, it's not that big. It's also still level between the two sides as far as I can tell.

Also wanted to ask about the grout spacing and depth of thinset for wall tiles... 6"X6"
I was thinking of 3/16, would that be okay for the grout

I use a 1/4 x 1/4 notch trowel for 12 x 12 on a floor. Wouldn't go quite that big for 6 x 6, so yea 3/16 x 3/16 should be ok.

I could be wrong, but:
1. grout spacing is a matter of personal preferance
2. the trowel spacing sets the thinset depth, to a point. IE-if you use a 1/4x1/4 you should end up with a 1/8 layer of thinset when the tiles are compressed?
3. Maybe adding the flexible additive would help prevent a crack on the tiles on the floor?

a crack isolation membrane is needed first before tile install.

like redguard.

kui****g, do you mean DITRA?

that would work well in situation
trowel thinset then roll Ditra
install tile over underlayment

Id use a 3/8" trowel for 12" floor tile with a 3/16" grout gap
and 1/4" trowel for 6" wall tile and maintain the 3/16" grout gap up the walls

Take the time to snap reference lines
Measure a few times to see what your left with against tub, against walls, afront the doorway, etc. (no little itty bitty pieces)
