Flooring Tile - Beginner questions on installing tile

I am about to install ceramic tile in my 3 season room. I am confident in the prep work, but as far as installing the tile i have a few questions. We are using 12"x12" tiles and i was going to use 1/4 inch spacers. Is this spacer too large? The second question i have is when i get to a wall. do i bring the tile right to the wall or keep the 1/4 inch space between the tile and the wall? Any help would be appreciated.

Thanks,
Pat

Personally, I think 1/4 is big, but it's a matter of choice.

When I use 3/16" I get +_ 1/16 space anyways to account for tile irregularities
and just general weirdness.
With 12x12, approaching 1/4" space is getting alittle "grouty". In my opinion.


Leave a small space at the wall, hide it with baseboards.

thanks for the help. Actually i will not have baseboards on 3 sides of the room. There are floor to ceiling windows there, so there is a small border of wood the window sits on, that the tile will go up against. Is it ok to keep that small space and use grout between the tile and the wall? I will drop the spacer size down to 3/16" too.

Thanks,

Keep the small (1/8") gap between the window wood and the tile. Fill with caulk, not grout. You want to leave room for the wood to flex, caulk will do that grout wont. Most grout manufacturers now make caulks in complimentary shades of the grout.
