Properties associated with porcelain include low permeability and elasticity; considerable strength, hardness, toughness, whiteness, translucency and resonance; and a high resistance to chemical attack and thermal shock.

The density of porcelain tile makes it more durable than ceramic tile while being less subject to wear and tear. This makes it more suitable for commercial use as well as in the home.
Porcelain tile is almost impervious to water.
