 you know, with the caulking. And bathtubs are different because, you know, where you have the tile and it comes down to the tub, and there's usually caulking there. And the reason there's caulking there is if you put the grouting all the way down, it comes all the way down to the tub, and you put 200 pounds of water in there plus your body, that tub is going to settle. It's going to move, and that grout's just going to crumble out. That's why there's silicone there.
