Tiles are different from each production batch

My house originally comes with 1x1 floor tiles. One of the main reason for me to changed them to 2x2 during renovation was because I couldn't find the matching 1x1 floor tiles, not even from the house developer, because the tiles of the same batch was finished.

Tiles are different from each production batch, especially in term of pattern and colour tone. The variance in batches for good quality tiles might be minimal, while the variance for ordinary tiles might be obvious.

Therefore, for new house owners, if you can foresee any renovation works that require additional tiles, be it floor tiles or wall tiles, you should quickly get from your house developer while the stock of the same batch is still available, or ask your renovation contractor to source for the same batch of tiles from the market while they are still available.

The same could be happen to paint. Different production batch of paint with same colour code is still slightly different in colour. The difference for good quality paints might be minimal, while the difference for poor quality paints can be obvious.

The problem in paint can be easily solved by repainting the whole wall with the new one. Same method applies to the problem in tiles, but involve in more cost and effort, i.e. to replace all the tiles of the same area with new one. This is exactly the reason why I changed the floor tiles downstairs to 2x2. Since the original tiles need to be replaced due to non-matching colour tone of different batch, might as well upgrading them from 1x1 to 2x2.
