What is the purpose of a level in tile installation?

In tile installation, a level is an essential tool used to ensure that tiles are even and properly aligned. This is crucial because uneven tiles can lead to aesthetic issues and may cause problems with water drainage or structural integrity over time. When tiles are not level, it can result in raised edges or gaps that not only appear unprofessional but can also lead to cracking or breaking of the tiles.

Using a level helps the tilesetter establish a consistent plane during the installation process, which is vital for achieving a flat surface across the tiled area. This is especially important in environments like bathrooms or kitchens, where water might pool if there are low spots, leading to mold or damage. By confirming that each tile is placed correctly in relation to the adjacent tiles and the overall surface, a level assists in achieving a high-quality finish that meets both functional and aesthetic standards.
