grout question

I am tiling a bathroom backsplash over a granite vanity top: the tile is mixed marble and glass, 3/4-inch x 3/8-inch mosaic tile. The grout lines for this tile are pretty small.

At the same time I am also tiling a small area behind the toilet with 6-inch square ceramic tiles, where the grout lines are 1/4 inch.

At the tile store we ordered unsanded pearl grout for both jobs. Is this OK for the 1/4-inch joints, or should I use sanded for that and unsanded for the mosaic?

Wall tiles look best with 1/8" grout lines in my opinion. You can get wedge shaped spacers that assist in maintaining a consistant grout line. Wedge spacers on walls are easier to work with than the "+" shaped spacers. "+" shaped spacers work great on floors. I also try to use 1/4" grout for flooring applications only.

Maintain the wall at 1/8" for mosaic and ceramic will make it blend nicely and you can use the same unsanded grout.

Found a picture of 6" tile w/1/4" grout lines... I agree w/ Czizzi, looks too big on a wall.
