The correct answer is: The space between tiles filled with grout

The term "grout joint" specifically refers to the space between two tiles that is filled with grout. This gap is essential in tile installations, as grout not only secures the tiles in place but also provides a finished look while preventing moisture from penetrating beneath the tiles. The width of the grout joint can vary depending on the size and type of tiles used, as well as the aesthetic preference of the installer or homeowner. Grout serves several functions, including helping to stabilize the tiles and allowing for slight movement without damaging the tile itself. Understanding the significance of grout joints is vital in tilesetting, as it affects both the durability and appearance of the tile installation. Properly chosen and installed grout joints can enhance the overall design by drawing attention to the patterns and colors of the tiles.
