Marble is a beautiful stone. You will need to have it sealed regularly (every 12-18 months and unfortunately if you're a keen cook you should be warned that it can stain and acidic things like lemon juice and vinegar need to be wiped up immediately. I say this as if you're anything like me you tend to share a lot of your cooking with your splashback. The alternative would be to look for a caesarstone type material in a marble pattern - Caesarstone and similar products don't need sealing, aren't porous and are more stain resistant. Good luck.

Looks great from what is shown, but could you post a photo showing the whole kitchen please? I am having the same dilemma and very keen to see more of your tiles.

okay!!! A lot of these commenters obviously thought what I did - that the cupboards are a deep browney grey!! I think the responses would have been very different if we knew the cupboards were white. If you re-read thru the responses you will see that. Perhaps try re-posting the dilemma with a better pic. One of those original tiles may actually look ok.

These are my hand made Spanish tiles. They have the undulating surface which give texture and interest. I think this is what the blue tiles are. Hope you locate the blue tiles, the kitchen will look fantastic. I wish now I had taken more risks with colour, and not listened to my husband.....oh well, maybe our next house....
