The price of a tile depends on several criteria :
The nature of the tiling : the material of the tile, its trade mark, the use for which it is intended and its quality ;
The surface to be covered : since the price is expressed in m2, the surface to be tiled is extended, and the greater the total amount of the project will increase ;
The tile dimension : large tiles are expensive, and are heavier, their manipulation, their layout, and their poses (double sizing, need for a second tiler) will be more complicated and therefore more expensive ;
The state of the wall : if it is in a bad state, it will be necessary to add the cost of the repairs to the total budget tile. Here is photos of our work.
