Most often, sanded grout is used for floor tiles because the grout lines are usually greater than 1/8" wide. Sanded grout is necessary for the wider lines to give added strength, and to keep your grout from cracking and chipping out. Unsanded grout must be used if your grout lines are narrower than 1/8", because the grains of sand in sanded grout could cause air pockets and prevent good adhesion to your tiles - and it will crack and chip out as well. Sanded and unsanded grouts are cement-based.

One alternative grout on the market is epoxy-based. It is neither sanded nor unsanded, but will work fine in either narrow or wider grout lines.

If your grout lines are wider than 1/2", or if you are using saltillo tiles, you must use saltillo grout. Other grouts will not handle this wider width.

Can you use wall tile grout on floor tiles?

You can. It is less gritty but it works. Edit - While this is true, it's important to understand the wall grout is designed for thinner grout lines, so if you use it on the floor, make sure your grout lines are thin. Otherwise, the grout will crack.

What is the difference between sanded and non-sanded grout?

The obvious answer is sanded grout has sand. But the in depth answer has many differences. Sanded grout which is the most common, can be used in a grout joint from 1/8" to 1/2" (and larger but check the grout). Sanded grout scratches many tile like glass. Non sanded grout can only be used on joints 1/8" or less. Non sanded grout is typically seen on marble and granite tile, many wall tile, and all glass tile.
