For small apartments, a bright tile of cold tones is best suited, which can visually increase the space of the room.
Dark tiles of warm tones, on the contrary, visually reduce the room, thereby making it more comfortable. As for the drawing, the tiles with large ornaments looks great in large rooms, and in a small room it will make an oppressive impression. In a room with low ceilings, it is better to use tiles with a vertical pattern, which will visually increase the height of the room.
