I don't do anything but granite with undermount sinks, usually kohler's. For bathrooms, I find that very little dirt accumulates under the rim - kitchens, on the other hand, are a commpletely different story, though, I do granite and undermount stainless sinks in that application. Granite is a real eye-catcher - it's all the rage with home buyers.

I have a single sink vanity in the bathroom off our master bedroom (which unfortunately is not a master bath) and another single sink vanity (a few inches bigger) in our master bedroom. We are looking to keep the cabinets but replace the counter tops. We have the faucet and above-counter sink in mind. Those would require two cuts on each countertop: one for the faucet and one for the drain. For a visual of the idea here is the sink and the faucet listing on amazon, its the white rectangle sink and the brushed nickel faucet (https://www.amazon.com/gp/product/B018S1Q0VU/ref=ox_sc_act_title_1?smid=A3SE6K3TNDHAFT&psc=1). We are new to do the DIY world of home improvements but we're fearless and love to learn, so beat with me if I lack knowledge of terminology, I like to make up for that with a detailed explanation! So the vanity inside the bathroom is in a corner and touches two walls: the back and right side wall. The vanity in the master bedroom touches three walls: the left and back wall and a right half wall. So I think we will require the backsplash that matches the countertops for the sides and back of the counters. So, I'm here trying to find the best route to accomplish this DIY. We live south of Denver, CO and would like to install it ourselves to keep costs down. In addition to keeping costs down, I've been advised to check out remnant yards of stores that sell/install countertops since we don't need entire pieces like that of a large kitchen counter. Since these two vanities are separate but relate to the same bathroom, I am keeping the consistency across the two. We are not set on the color or the exact rock, so we are open. Please feel free to share any advice you may have! Again, we are inexperienced but everyone has to start somewhere and we are eager! I will post pictures and measurements of the vanities when I get the chance! Thanks in advance!

Sure, if it looks good with the paint. It would have to be a few shades darker. Since Gray Owl, on the card with the progressively darer shades, looks like it is a greige, the darker colors become brown. So you would have to go to the paint store and find a charcoal that looks good with the greige color. If you go to the Benjamin Moore site (google Benjamin Moore Gray Owl) they will lead you to look at the color in different rooms, and it you go to where you can change the colors for the different elements in the room you will get the chance to see the Gray Owl with other colors. I see it with Silver Spring 2120-50 and it looks great,, a darker gray that will look nice with Carrara. Not Charcoal, but charcoal is awfully dark. This is from that site and it purports to show Gray Owl walls and Silver Spring doors and fireplace. It is worth a look, as the combo looks like it might go nicely with the Carrara. Your veins are quite dark, so might take a darker color. You are there and you can see, we can't, go to the paint store and see what looks good with the marble, take a sample with you to pick out the paint.

Thanks all. That was the direction I was leaning, but it’s nice to know I’m on the right track, especially as I start to hit decision overload. The tile Themar by Arizona Tile in Venato Gold. We looked at a LOT of options, and at the last minute my tile showroom happened to start carrying Arizona Tile, and we really liked this one.
