I have the same question really, except I know I have to have laminex and don't know which would look best. We live in the country where it's hard to inspect sizeable samples in situ

I think the look you are going for is gorgeous! But I admit that I too am surprised your considering a smoky mirror splashback if you dislike glass? But again, it all depends on the vision you have for your kitchen. As Dr Retro has wisely pointed out, depending on what is opposite, will depend on what you're reflecting... or, what you have on your kitchen bench and if you want to see it doubled. I think in certain applications, smoky mirror splashbacks can look really beautiful but if you're not fond of glass, why not start with a material that you love and go from there? I have developed a bit of a thing for Southern Cross Ceramics and all the different tiles they have available - in beautiful colour tones, patterns.... aaaaah it's hard to make a decision! It doesn't need to be a dark colour if that is not where you heart lies, but some soft muted colours could work beautifully. I also saw a designer recently laid I believe it was a mix of matt and gloss white subway tiles in a herringbone formation (correct me if I'm wrong anyone??) so that it had a little twinkle here and there... it looked beautiful. As much as I love a mostly white kitchen, I think a little colour & texture that compliments your marble would be a great way to go.I even saw some silver/copper foil looking tiles as part of a splashback to give a kitchen that bit of glam. Before you commit to smoky mirror splashback, maybe have a look at some other options that will compliment your style and see if anything else grabs you :) Good luck.

Getting a quote on the Grande Statuario. I think it’s going to be significantly dearer than our first quote ☹️ The crispness of the White is perfect with great veining. Second quote being done with main island in the Statuario and with Smartstone along benches under window and into pantry, in case the first is too dear. Took our Lexicon 1/4 and overhead samples with us. Really happy with the choices. I just hope the first quote isn’t too dear as I’d prefer all white but I’d be happy with the combination of both tops.

Love the sound of the style for the studio. Pick the stone you love and get a sample. You can then pick up a colour chart or from Bunnings and narrow down a couple of white choices that work with the stone. You can then paint or order larger samples of the white and see what you think. My opinion is that the Silestone is the better choice. It’s still a clear white but a touch less bright which would work with the look you’re after.
