When choosing whether to fix or replace a tile, keep the following things in mind: 

 

Damage severity: If the tile is only slightly cracked or chipped, it might be repairable. However, it is probably advisable to replace the tile if the damage is significant or if it has been broken into several pieces. 

 

Age of the tile: If the tile is still quite young, trying to fix it might be worthwhile. To prevent further problems, it could be preferable to replace the tile if it is old or was of poor quality to begin with. 

 

Size of the damaged area: If the tile is only partially damaged, it can be more cost-effective to repair it rather than replace it entirely. However, replacement can be the best choice if the damage is severe and covers a significant portion of the tile. 

 

Aesthetics: If the damage is obvious and impacts the tile's overall appearance, replacing the tile may be worthwhile to preserve the room's beauty. 

 

In the end, whether to repair or replace a tile will rely on the particular situation and the severity of the damage.
