Ceramic
Both glazed and unglazed ceramic and mosaic tile do absorb water, dirt, and oil, therefore need protection and maintenance. Furthermore, foot traffic will wear the surface and slip accidents may occur, unless a regular care system is incorporated and maintained.

Porcelain Tile
Porcelain tile has an extremely low absorption of less than 0.5% (impervious) and dense composition; still, there are concerns regarding dirt and oil, slipperiness, and care of grout joints.
