thank you so much - so if I just remove the loose grout it should be fine - or should I spend the time and get the majority out.

Our recessed shower had had its tile to tile corners grouted but have now cracked and I have to say i do not think they are too old. The tiles are on a backer board but stud wall behind that! I assume the movement was too much. I think it was flexible tile grout but still!
I have seen...
