I would consider something light with some other colors to mix in like this. http://t.homedepot.com/p/Silestone-2-in-Quartz-Countertop-Sample-in-Mont-Blanc-SS-Q0220/203674451/ I like the wood paneling and would paint it a white with a warm feel to it. A white will reflect a lot of light from your large window. I wouldn't paint the window casing as it might tie in better with the rest of the house. Good luck!!

Not keen on tiles ... prefer a smooth surface with no grout lines to try and keep clean

What about colour , character and personality ? A splashback with a pond and a tree may be great , or look naff , as the Poms would say . Potentially , its on the right track , but look at pic 3 . Gone to sleep yet ? Probably $30k spent on nothingness . Now look at pic 3 , and imagine your splashback . Even if it is ( cringe ) black and white too , it will actually add to it . A bit . I don't like the particular light used in pic 1 , but its got character , you notice it , it is not totally bland . Pic 3 is .
