cracking grout

I have ceramic tile for my shower surround. I am having problems with the grout cracking and falling out where the wall tile meets up with the tub. I have scraped out the old grout and replaced it with new grout several times, but it keeps cracking and falling out. Any suggestions would be helpful.

This joint between the grout and the tub needs to be filled with caulk, not grout.

Depending upon what brand of grout you used, you can likely get a matching caulk from the same manufacturer. Ask at the same store where you acquired the grout.

If matching pre-colored caulk is not available, some retailers (big-box, paint stores, etc) offer custom-colored caulk.

Thank you for your quick reply! I actually removed caulk from around the tub when we moved in because it was moldy and stained. The previous owners had used clear caulk and were not very clean. If I put in caulk, is there a way to keep it from molding and turning black?
