I have a question about laying mosaic tile on a bathroom floor. Our builder jsut installed our 1" round mosaics (on 12" squares) in a guest bath. We went to check it out yesterday. It has not been grouted yet, but there are visible gaps between some of the squares. Is this something that grout will cure, or is this bad installation. I'm meeting with the builder today to discuss and I want to know how big of a deal I should make of this. I have a picture, but it's hard to see the gaps becuase the pic is taken too close up.
