I had a tile backsplash (mosaic tile of a herringbone pattern) installed in my kitchen. I wanted tile border to match and for the tile to wrap into the window above the sink. the way the corners look going into the window sill are not at all what I was expecting. The grout line ranges from 1/4" to 3/8" thick,
They told me that making a thinner grout line or a 90 degree angle would have exposed the inside color of the tile and the rough edge, but I think the way they did it looks pretty rough and chipped. When I asked them to fix it they added more grout and said that the only other thing they could do would be to rip it out. These are pictures after the additional grout -- How should they have done these corners? Can anything be done to fix this (short of ripping it off the wall)?
