Regrouting is a cosmetic process that cleans up the look of your shower. It is appropriate when the grout is merely discolored, stained, or has superficial cracks, provided that the tile itself is firmly bonded to the substrate and there are no signs of moisture intrusion. If you want to refresh the look of your shower to make it look brand new, removing old grout and installing new, high-quality material is an excellent, cost-effective maintenance step. However, if your shower shows signs of water damage—such as crumbling walls, mold, or hollow tiles—regrouting is not the correct solution. It is a surface-level fix that will do nothing to stop a failure in the waterproofing membrane beneath the tile. In these instances, the damage has already moved into the structural components of your home. Before you commit to the labor of regrouting, perform a thorough inspection to ensure there is no deeper problem. If you suspect your waterproofing is compromised, you should prioritize a structural investigation over cosmetic grout work.
