Floor tiles are tiles with water absorption between 0.5%- 1%, such as polished tiles, marble tiles, glazed tiles, polished crystal tiles, porcelain antique tiles, etc. So it is the most suitable floor for kitchen and bathroom, so that the floor will not be affected by water vapor.
Wall tiles are tiles with water absorption of 3%-6%, some even higher, and the back is rough, which is specially used to stick to the wall.
