Here are four options I have pulled together to get a feel in direction for selecting a backsplash for the kitchen. All four of these would compliment the white quarts countertop and the gray tones in your new home. However, don't feel as though you must select your final decision from these four options. If like the design concept of one, but would like to see more options in that direction, I can provide more similar options. 

Option 1: is a more decorative mosaic style option. This would be more of a statement in your kitchen and not as subtle as the others. 

Option 2: is more of a stacked material design pulling in different materials, all in gray tones. 

Option 3: is a more clean line, monochromatic, sleek style. The darker gray will pop against the white cabinets and countertops and pull gray into your kitchen from the other areas in the home. 

Option 4: is your more traditional white subway tile. This is a staple farmhouse style backsplash. 

You selected option 3 from the samples above. Here are four options that are more along the line with option 3 from above. Although these may look different in tone they all have a gray appearance to them. I will be mailing these four samples for you to see in person. I want you to pay attention to size, texture, and appearance. Note what you like and don't like. 

Option 1: is a longer and has more of a texture to it. It is a light gray in color that would compliment both your wall color and the center islands color. This would be more of a statement in your kitchen and not as subtle as options 3 &4. 

Option 2: although it appears really brown in the sample above this tile pulls more of a gray tone when put in a gray surrounding. It has a muted gray center with a slightly white edge. It also offers a nice texture and crackling look. This would really compliment the white cabinet and the grays in the quarts.  

Option 3: is a glass tile that will appear more clean line, monochromatic, sleek style. The darker gray will pop against the white cabinets and countertops and pull gray into your kitchen from the other areas in the home. Although it appears almost black in the sample above in person it is a nice dark gray. 

Option 4: is also a glass tile but in a lighter gray option. This tile is also slightly smaller than option 3. 

Here's what I need: Let me know which of the above you like the most.  I will also me mailing these samples for you to see in person they will be labeled on the backs. Feel free to decide once you receive them in the mail. In the comment section below let me know what you like about your selection. Again if none of these seem like "the one" let me know which of these is the right direction and I can provide more samples.
