Hi. Is it the pattern you like or the colour? Or both?! Laura Ashley do the Isodore tile which you may like but it's in black and white. You can use this for feature walls etc. there are lots of blue floral tiles around but unfortunately I haven't seen anything similar to this

Try wallsandfloors. They have a largish (50x50cm, if memory serves) patterned encaustic style tile in these very colours and a similar style. They're about £20 psm. Assuming it's still there, but I had samples of this tile delivered in autumn 2014.

Laura Ashley or v&a collection from British ceramic tile. Or Hemingway collection.

Beautiful tile by the way!
