Have you tride wallsandfloors.co.uk? They have an interesting selection One example might be: https://www.wallsandfloors.co.uk/fitzrovia-tiles-indigo-blue-cube-decor-tiles Or Fired Earth.. http://www.firedearth.com/tiles/range/palazzo/mode/grid Or these guys seem to have quite a selection, but I’ve never purchased from here so can’t attest to quality or reliability - somone else might be able to vouch for them! https://www.tonsoftiles.co.uk/vintage-patterned-tiles.html Have fun!

Hi minnie, I've just ordered the latte oblique mix range from Mandarin Stone, but they also come in a dark grey which I think are quite similar to your photo: https://www.mandarinstone.com/product/oblique-dark-grey-base-porcelain/

They do hexagon zellige tiles here so may be worth a few samples https://zellige-tiles.com/zellige-factory-stock/

Does anyone know where I can find black and white rectangular tiles (like the ones pictured), but much smaller (mosaic or up to 30cm wide)? I have attached a picture of the style I am looking for in white. Any help will be greatly appreciated!
