1/8" gaps - sanded vs unsanded grout

The contractor doing our bathroom floor tile set 12x24" tiles using 1/8" spacers. I had bought sanded grout from the tile store, but he insisted on using un-sanded as he said the sanded grout would not get down in between the tiles enough and would end up cracking over time.

I'm wondering what others have to say about it? I've never used un-sanded grout anywhere. He only put it under the vanity so that the counter people could measure over the weekend, so I could potentially switch back to sanded even though he was adament against it.

Hi Terry,

1/8" is the middle ground where either can be used:
Unsanded grout shrinks and it's meant for sizes up to 1/8"

Sanded grout doesn't shrink like unsanded does and is meant from 1/8" up to about 1/2". There are some differences among brands, but doesn't change the mentality here. Sanded will get down into 1/8" joints if it's packed properly. If his technique involves whipping over the surface like a quick squeegee pass, then it most certainly isn't being packed down into the joints.
If sanded was appropriate for the tile (meaning that it's not a polished stone that could be scratched by the sanded grout...or any stone tile that could ever be potentially re-polished/ground in the future), I would always use sanded. What type of tile is this? Natural stone or man-made?

The look is different, unsanded is (often only ) slightly smoother. Sanded is stronger and, as already mentioned, doesn't shrink. Normally, as long as the grout lines are really no more than 1/8", unsanded won't shrink enough to show a crack. If mixed properly, and good technique is used, either should work while unsanded MIGHT be a little easier to install - it's not supposed to be soup, regardless, it must be packed in there, but it's easier with unsanded. It's easier to get pinholes with unsanded when packing the grout in.
