We just had a concrete tile show installed which I plan to grout. So the question is, which edges need to be grouted and which need to be caulked. I plan on caulking the all the edging where the tile meets the wall/floor/ceiling. Does the inside corner need to be caulked or can that be grouted. What about where the wall and curb meet the floor tile.

The second question is where the top of the curb meets the side of the curb, it looks like the tile was cut to fit tight (no spacers, the top piece abuts the side piece). How should this be sealed?

Thanks in advance!
