Do you think the tile, countertop, and cabinets work together? Looking for reassurance.... we gutted the kitchen and started from scratch, and it's frustrating to be have this question at very end. Thank you for taking time to answer!

Jamie, i think it looks good. grout with a gray grout. I love Jan's ideas.

Thanks all! That wood trim is throughout our house..... windows, doors, door frames, crown, etc. Just working with it instead of redoing it!

Yes paint the window and trim the same white as the cabinets as recommended above! Use a light color grout so you can see the tile pattern. Probably CBP (Custom Bldg. Products) 'Snow White' or maybe 'Platinum'. Difficult to tell via computer photos. You're on the right track! Best of luck!

Any opinions on grout colors?

look at warm gray by Mapei. avail at Lowes. make sure you do a 100% silicone (same color as grout) for the joint between the countertop and bottom row of tile. No grout there.

Jamie Ferguson, I wouldn't paint the window if you have wood details throughout the house. There are many examples of kitchens with wood and gray tones and it actually seems to be a new popular thing. The gray tile, white cabinets, and the countertop look great together. I am doing similar colors in my kitchen reno and wish my husband was behind switching out the boring tile floor (hard on my back) to wood but won't hear of it! I'm surprised people are suggesting you match the grout to the tile. If the tile were white, I would agree, but maybe you should look for photos of tile with contrasting grout to be sure. Congrats for nearing the home stretch of your reno!
