Cracked grout around tub surround
The grout that meets the top of my tub has cracked. After some research there appears there are two schools of thought: 1) grout 2) caulk
Grout obviously has a tendency to break and crack due to the shifting from the tub due to the weight changes, but also allows the water to exit behind the tiles. Caulk stays in place due to its flexability but traps mold, mildew, moisture, etc behind the wall.
With that said I am not sure what to do. Re-grout only to have it break again? Or caulk and have mildew growth. Also the corners of my tile shower surround have cracks in the grout.
Lost as to what to do! Thanks in advance
