You might get away with a strong 1/16" wide gap between the two filled with a color matched silicone. You'll want it wide enough that it can allow for the different rates of expansion and contraction and easy replacement. No mechanical fasteners between the two please. The butcher block is much more dimensionally stable than a few wide boards.

@joseph_corlett Thanks, that’s helpful. In terms of expansion and contraction, is there a direction in the wood that expands more, i.e. at the end grain or side grain? In other words, is there a preferred way to align the wood boards along the quartz?

Here’s what I’m going for:

@jan yes, I’ve been thinking a brass would go nicely. What would you recommend for backsplash? I’m debating a 4“ continuation of the same quartz material, or a tile, or maybe just paint. I’m not sure I want the very modern feel of doing veined quartz on the entire backsplash... worried it will feel cold.

I only have one fairly short wall of backsplash behind the sink, D/W, and and stove - it’s about 20” high, and 30” high behind the stove.

We're not seeing your existing space. A four inch splash feels a bit lonely. Tile is great, wait until tops are IN PLACE is the best idea. .... and skip the four inch riser at install . There is zero need to select now, unless your choice would be a full match to your quartz/full splash. Outlets would need to be cut into that as well, so that's additional expense, beyond more material, and needs template of course.

Don't give partial information. Show the space, your cabinet style, the gray, the black......all selections to now. Piecemeal questions, will only get you piecemeal answers : )

Stay n the same thread, and don't begin a new thread.

Got it, that makes sense. The kitchen cabinets are not fully installed yet so I don’t have a completed picture but here’s a progress update.

The island has a matching shaker door, but in black (see original post for exact door), and the quartz countertop is pure white with black veining (see in original post). There are wood shelves in the island as well to break up the black and wood floors in kitchen and both sides of island. The faucet is brushed brass, the sink is white apron front, and the drawer pulls will either be brass, black, or leather.

For backsplash, I was worried that tile grout might be a pain to clean, but maybe it’s not that challenging? If we went with tile, I was thinking of zellige square style / hand cut tile, perhaps dry stacked (maybe white, maybe a bold color?!) . I’m happy to wait on this part, but I just know that these tiles can take weeks/months to arrive so trying to get ahead of that.

Brooklyn- I know this is an old post, but I am looking to do something very similar in my kitchen. Did you end up doing this combo countertop with Quartz and butcher block? Our countertop installer is unsure how to join the two surfaces. I've scoured the internet, but can't find any information on how to do this. I would be so appreciative if you have any advice!
