Ohh I'd love to know too! I love the look of pressed tin splashbacks like this - I feel like they would be very durable (and easy to clean!)

Ali your kitchen looks amazing. The colours are wonderful. I have a question for you about the Rugged Concrete. I’m thinking of using it on our island bench but I’m a little worried about finger marks and cleaning. I’ve read lots of bad reports about the other Caesarstone concretes like Fresh,Raw and Sleek. And I’m hoping Rugged Concrete is easy to clean. How is yours now that you’ve had it for a little while?

It looks pleasant enough , and personally I'd keep the benchtop as I like the warmth of the wood -- a bit of age and wear adds to the character IMO . I wouldn't glue anything over tiles -- I'd chisel and sand and get a decent base , as I'd be worried moisture , bacteria , food waste would somehow get into the grout and gaps etc , even if you put skirtings around the edges . Mind you , I prefer tiles , be they square or subway or modern with metallics , they seem more interesting than a coloured piece of glass ( splashback ) , even if tiles are potentially more work . Maybe I'd just update my tiles , but I'll want and see your new photos .

Your first inspiration pic using the benchtop material which is a fabulous solution if you can afford it. The scale of your pendant light is a bit small to give you the wow your after so maybe you could have under cupboard lighting that reflects off the splashback. That way you won’t need to go too flashy for the splashback.
