Tiles are laid at the four corners of the figure of eight, that is, the chamfering of tiles is on the figure of eight. Its biggest advantage is better integrity, no color difference, and its appearance is much better than the outer corner line. But in the process of construction, tiles need to be cut at a 45-degree angle.
Tile workers can grind edges on site. All tiles have high hardness and are easy to collapse, so they need to be cut in the tile factory. No matter what kind of cutting, they have to pay extra. Now labor is more expensive, and tile chamfering is not cheap.
