“We bought 2 extra boxes as we'd decided to tile more of our new bathroom. Unfortunately they are slightly longer and wider then the ones we'd already bought so don't line up. Thought we might get slightly different shading but not different dimensions”
I am sorry to see that the tiles are not suitable to continue your project.
Tiles are produced in batches, and as the manufacturers are unable to exactly replicate the conditions in the kilns for every firing, tiles may vary slightly in terms of shade and/or calibration from batch to batch.
If you require any assistance looking for the required batch, please do not hesitate to contact us on 01782 223822 or at customer.service@tilemountain.co.uk.

Joanna
