Please repost on the design dilemma option - in the "Flooring" area, a wall of glass tile probably won't get you many responses....and cutting glass tile requires SPECIAL blades and a special approach. Without both, this will happen over and over and over and over and....you get the picture.

The tiles look like they are install nicely, except for the chipping in the corner. I'm not one to use an excessive amount of caulk, but a little bead of white silicone might cover up the chips / gap. Ripping out those tiles may do more damage than letting them be.

Post in the bathroom forum to get more responses. The flooring forum is not the place to post this question.

Even if the glass itself is cut smoothly, the colored backing can chip off. There may be some way to touch up those areas so from the front the tile looks good

I say, if you're anal, don't use glass tiles.
