We have a tub where the surrounds are ceramic tile. I one or two area
the grout started to pit a little. It started as a very small pinhole
or two, now it's about 1/4 inch. My two questions are:
Is the easiest but right solution to just scrape out all loose material
in the area and put in new grout?
What can I do to prevent this from occurring again, or is this just the
maintenance involved with having a tile surround?
