Subway tile is always an affordable option and comes in a variety of colors that you can customize at Home Depot or lowes. You can also play with grout and add contrast. that's if you're being cost conscious. If you're looking at glass tile it's typically more expensive unfortunately. Must say I love that tile you've chosen... Might be worth the splurge ðÂÂÂ!

Maybe you could just use that tile in a few crucial locations, like behind the cooktop and sink? I have to agree it looks kinda like a perfect combo in your picture!
