Do tile showers need to be caulked?
Where grout is just good for bonding together tile, caulk is good for creating a seal between multiple materials — say, between glass tiles and a porcelain tub. Or where the edge of a tile meets the wall. Caulk is impermeable, meaning it won’t let in water. For bathroom or kitchen uses, silicone caulk is usually best.
What is the difference between caulking and grouting?
