In my last house (tract built 2002), the contractor caulked the joint where the side wall tiles meet the back wall tiles in the stall shower.
In my new (1956 fixer) house, the contractor I hired used grout in those corners. We have 13" tiles, 1/16" joint non-sanded.
It seems the grout near the bottom on one side likes to crack. I fill the cracking, but it comes out again. Probably not sticking to the sealer.
ANYWAY, what say you all? Grout or caulk where the side walls meet the back wall?
If you say caulk, I guess I should strip out that grout in the corners. But should I cut out some of the caulk where the tiles meet the pan to make sure no water got in?
The shower pan is a 30" square Florestone with those 1" channels at both sides of the front. Those are open, but the gap between the tile and pan is caulked with silicone all the way around from one of those channels to the other.
I have read some opinion that some gaps should be left in a few places in that caulk to allow wayward water to escape. If that happens, then it may get in at a spot where there is no gap. So why not just leave the whole thing uncaulked where the tile meets the pan?
If anybody could set me straight, I'd appreciate it. Thanks!
