I initially gave this tile 5 starts, it is beautiful. Unfortunately the tile keeps cracking in my master shower. After doing research it looks like you shouldn't use large glass tile in a shower because of the stress on the large glass tile. It seems to be that small glass tile is OK but this tile has now cracked for the 5th time. Always where plumbing fixtures are and the last time the plumber only tightened the fixtures enough so that he could then add a silicone seal around the fixture.  It cracked again!
