Grouting the Edge of a Shower Stall

The tiles that make up the surface of your tile shower have to prevent water from getting under the floor and into the substructure. The tile itself is completely waterproof, but the edges of the tile, where they are separated with spaces, is not. This is where grout comes in. Grout is a form of cement that you spread into the spaces between the tiles.
