Ceramic tiles are a useful floor covering because they are made by machine and each tile is consistent and predictable. The tile has low absorbency which prevents problems while the tiles set after being laid. They tend to be light-weight and relatively thin relative to stone. The bottom of ceramic tiles are specially roughened or lined to facilitate proper setting.
Unglazed tiles are useful for high traffic or wet areas and are slip resistant. They are scratch resistant but vulnerable to staining and therefore require a sealant and wax after installation. Glazed are less thick and dense than unglazed, but allow for a greater variety in color and style and are more resistant to stains. The different glazes can affect the strength and durability of the tile, so be sure to note how strong the tile is.

Consider the thickness of the tile as it impacts its durability and weight. Depending on the type of tile, it can also affect the cost. Also, if the height varies between rooms, ensure that there wont be step ups which can be easily tripped over if you use two different types of tiles.
Three practical things to think about are: size of the tile, sub-floor suitability, and how easily it is cleaned. The larger the tiles, the fewer youll need to fill a room, but each tile may be more expensive. The sub-floor may not accommodate certain types of tile. Check with the manufacturer. Ensure that the floor can be easily cleaned, particularly if its in the bathroom or kitchen. If its in a low traffic area or a wall tile, this is not as important, and is up to you.
Tip: avoid ceramic tiles with bright reflective surfaces for your floor because they are not resistant to abrasion and pose a slip hazard.
