I am having ceramic tile flooring installed in my bathroom as well as my kitchen. The contractor is suggesting 3/8" joints. What is the difference between sanded and unsanded grout? Which do you recommend?
Personally, I prefer as small a grout line as possible. Tile is glazed and
easy to clean, grout is not and tends to get dirty and stained easily, so
the less grout the better for me.
I would NOT go for 3/8" or even 3/16" if smaller were possible.

I recently had my bathroom remodeled. They used large tile on both
walls and floor. They said the wall grout did not have sand and the
floor grout did have sand. The floor tile joints or grout lines is
much wider than the wall.
I agree with other poster and use a small grout line perhaps 1/8 inch,
then unsanded grout is not a problem.
If the joints are 1/4 inch or more you should go with sanded grout
especially on a floor. If 1/8 inch you can use either sanded or
unsanded. Less than 1/8 inch then definitely use unsanded. But I too
have learned to hate wide grout lines for sanitation reasons.
The difference?... unsanded looks like smooth plaster, sanded looks
like mortar. When you buy the acrylic caulk to match the grout (for
tub and toilet bottom, etc) then match that as sanded/unsanded also.
Sanded grout has sand in it; unsanded doesn't. That's pretty much the
Unsanded grout is only for very small grout lines, like the 1/8" or
less in a shower. The sand makes the grout more durable. A 3/8" grout
line is wide enough to walk on. Use sanded grout.
