What Are Tile Batch Numbers?

A batch number (or shade number) is a unique identifier printed on a tile box that indicates the production batch of the tiles. Each batch may have slight differences due to: ✔ Raw material variations ✔ Firing and glazing conditions ✔ Color pigmentation changes ✔ Manufacturing processes

Even if two tiles are from the same manufacturer and product line, differences in batch numbers can result in slight variations in tone, texture, or size.

Why Matching Batch Numbers is Crucial

1. Color Consistency

Tiles in different batches may have slight shade variations, which can create an uneven look on large surfaces. Matching batch numbers ensures a uniform color tone across your project.

2. Size & Calibration Differences

Some tiles may have microscopic size variations between batches, which can cause alignment issues when installed. Consistently using the same batch ensures a precise and seamless finish.

3. Glaze & Texture Variations

Tiles from different batches may have differences in gloss level or surface texture, affecting the final appearance. Mixing batches can lead to patchy reflections and inconsistent finishes.

How to Ensure You Have the Same Batch

✔ Check the tile packaging – The batch number is usually printed on the box. Ensure all boxes match before starting installation. ✔ Order extra tiles – To account for breakages or future repairs, always order at least 10-15% extra from the same batch. ✔ Buy all your tiles at once – Purchasing tiles in multiple orders increases the risk of receiving different batches. ✔ Inform your tiler – Ensure your tiler checks the batch numbers before installation. ✔ Lay out tiles before fixing – Dry-lay the tiles first to spot any inconsistencies before they’re permanently installed.

What to Do If You Get Different Batch Numbers?

If you find yourself with tiles from different batches, you can: ✔ Mix and blend the tiles – Randomly lay them out to create a gradual transition. ✔ Use different batches in separate areas – Keep one batch for the main area and another for accent walls or less noticeable sections. ✔ Consult your supplier – Some manufacturers may be able to locate tiles from the same batch.
