I'd do the buff grout with the subway tiles. Sometimes the contrasting grout can feel old more quickly than a grout that blends in more seamlessly. Don't think I'd do white grout with your colors, though, too stark.

Thank you so much for the suggestions. Baltic Blue is gorgeous. I like Amadeus as well, but worried about it clashing with the floor. The cabinets are not raw wood. They are not high quality cabinets, but we just can't replace them. We are going to be able to get new counters, add a breakfast bar and an undermount sink for $1600. I estimated new cabinets would cost an additional $4k to $15k and we don't want to make that big of investment in the kitchen... We got a great deal on the pulls and plan to put in new light fixtures and then call it done. : )

jrueter thanks for your thoughts. Another concern I had with tile rather than granite is that the area behind the sink might look a little "choppy" rather than integrated if I have granite on top in the window, then a backsplash, then granite on the counters. I've read the post by tbosshar about her backsplash and I think I might feel the same as she did (she didn't like the look). I've looked at the backsplash pictures and have some great ideas for my next house!

Thanks everyone for your input! It really helps! Davidro1 - you were so right about communicating with customer service (slapping my forehead - why didn't I think of that). I actually called them, and they were so helpful. Here's what they told me (in case anyone else on the Forum is looking at KWC too): Splendure SS vs. solid SS finishes - KWC's Splendure finish is an imitation SS with a PVD coating, an electronic process which makes it stronger and more durable that real SS. Splendure SS won't tarnish or darken with age. KWC's "Solid SS" is exactly that. Solid stainless steel has oils in it and will darken after some years and need polishing. Why the Luna specs don't mention a lockable spray - the Luna faucet actually does have a locking spray (as Chipongo noted above). But to reset the Luna back to regular flow, you either have to turn off the faucet, or lower the handle to lower the water pressure until it goes to regular flow. On the other KWC faucets I am looking at you turn the button to reset back to regular flow (I'm not quite sure I get the "turning" action, I'll have to look at that in the showroom). Side handle vs. handle in the back - solely personal preference, except if you have left-handed family members who would do better with handle in the back. Systema side handle vs. Domo side handle - in Europe, the Systems side handle style is considered more modern, and the Domo side handle style is considered to be traditional (vs. U.S., where "traditional faucet" means a more "colonial" look). The rep advised looking at my appliances and cabinet handles to help choose. I.e. if my appliances are e.g. Gaggenau (or the like), and my handles are the modern tubular style, then the Systema would fit better. If my appliances are more GE/Whirlpool (not his words, my words, cause our appliances are!), then the Domo would fit better. Any other input would be welcome. Thanks everyone.
