We are finishing up our pool and noticed the rather large gap between the tile and coping which is filled in with grout. In most places it is 1-2 inches. Is this going to be a potential problem down the road as there are already places were the grout is separating from the coping? Or is this just a cosmetic issue? What is a standard distance for this to be? Please see images. For reference the tile are 1inch squares. Also should this be fixed or is more trouble than its worth. Any advice would be greatly appreciated.
