| Chip larger than a coin | Fill, but expect it to show |
| Crack across the tile | Replace the tile |
| Tile is loose or hollow-sounding | Replace and re-bed |
| Several tiles cracked in a line | Investigate — may be a subfloor problem |
That last row matters. Cracks appearing in a straight run across several tiles usually mean the substrate is moving or a joist is flexing, and repairing the surface won't stop it recurring.
The hardest part of replacing a tile is finding a match. Tiles vary between production runs, so even the same product bought later can differ in shade. This is why the standard advice when tiling is to keep a box of spares from the original batch. If you have none, check the back of a removed tile for a manufacturer code, try the original supplier, or look for a tile from a less visible area — inside a cupboard, behind an appliance — and move that one into the visible spot, putting the mismatched replacement where it won't be seen.
Chipped edges and corners near doorways or bath edges are best filled with a colour-matched epoxy and then protected with a trim or edging strip if they keep getting knocked.
When to call a professional: cracks spreading across multiple tiles, tiles sounding hollow over a large area, movement in the floor, or damage in a wet area like a shower where a failed repair risks water getting behind the tiles. Those are structural or waterproofing issues rather than cosmetic ones.
Preventing the next one: the usual cause is something heavy dropped, so mats in kitchens and felt pads under furniture help. Keeping spare tiles from the original box is the single most useful thing you can do.
