Shower grout that looks fine from the outside is often the grout that's been sending water into the wall for a year or more. Cracked corner joints. Failed adhesion at the tile face. Grout at the corners instead of caulk. This episode covers the full regrout job from diagnostic to seal: how to find where the water is entering, why the oscillating multi-tool is non-negotiable, the prep that determines whether the new grout holds, the right consistency, float technique, caulk placement, and sealing sequence. Based on a hard lesson in a fifty-year-old house where the grout looked presentable and the backer board had been dissolving for two years.
