Not to worry! Get in touch with us as soon as you realise and we will do our best to ensure we can provide you with stock from the same batch!* We usually suggest ordering 15% wastage to ensure you have enough and to avoid any risk of not being able to get additional stock from the same batch. Tip: make sure you take a photo or note down the details on the box your tiles come in as this is where the batch number is listed and is what we use for batch matching. If you don't tell us the batch number, we're not able to look into the possibility of batch matching. *While we will do our best to provide you with stock from the same batch, we can't make any promises.
