There is a Read Me First thread with instructions on how to post an image. Images of your space, materials, and inspiration images would be helpful, as would an idea of your tile budget in $/SF.

Thanks for your advice. I drew a draft for the general layout of the kitchen.

Also would like some ideas about the decoration in the other side of wall. There is no any cabinets on that side. The cabinet style is transitional. Thanks

You might try searching Houzz kitchen photos with the fliter Silestone Lagoon. On a super quick search I ran, here is a photo of Lagoon counters and a short Lagoon backsplash. (They used tile for other parts of the BS). That might help you decide if you want to use the Lagoon on both surfaces.

OK, just for fun, here is the range wall BS in that same kitchen.
