We always send a representative sample from the current batch of tiles or paving we have in stock, so as long as you requested a sample close to the time of purchasing, this will help to ensure the tiles and paving you receive matches  the sample you have been sent as closely as possible.
All of our products are either natural or porcelain and therefore there  is always scope for variation in shade, colour and to some extent the texture and finish with the natural products and with porcelain there will always be some slight colour variation between different batches, although the surface texture and finish will remain largely the same.
We would strongly recommend that you visit one of our showrooms or paving displays to look at the current selection, so you can be entirely sure of what you will receive.
