Hi Shalyn - thanks for posting your question. With your requirements in mind, I believe large format tiles are a feasible option for your backsplash, and White Valencia is surely leaning towards that timeless look. So good choice there.

If your open to more options, I'd also recommend looking for tiles with a pattern to it. I mention this because often times, with a standard size backsplash tile, the overall pattern created by the size of tile and grout color/placement aids to the overall design and look - especially at a distance. Once we look into large format tiles for small coverage like a backsplash, the (fewer) grout lines from due to its size begins to create direct sightlines. And because they become only part of 'functional design' rather than also 'aesthetic design' - we just need to be mindful of same and learn to work them strategically. Either choosing to align them with some of your existing cabinet front edges or by seeking to minimize the look of them entirely.

With that clarified, a large format tile with smaller scale pattern (almost the look of mosaic) will help to hide those occasional vertical grout lines. They will help tie in the multiple pieces for a cohesive look, too. This could be especially nice with your kitchen specifically, as you have that light colored cabinetry which already encourages the eye to run vertically (due to spacing between them, and the grain direction).

So, choosing a backsplash that either allows the eye to hover in one place (with a smaller scaled circular or geometric pattern) OR horizontally (White Valentia with a soft/subtle wave-like veins rather than others with quite rigid lines) would be a lovely choice for you.

Regarding your sink choice, I do love a black sink. However, if you have hard water - I advise against it as those unsightly water spots will prevent you from seeing the beauty of that sink each time you walk by! If all is okay with your water, stick to an undermount with crisp corners (ideally your countertop to have the same crisp corners too). Then, a faucet with at least some matching finish components, yet without installing the 'faucet plate' most often come with it. That, together, will be a kitchen with a very inviting mood!

Hope this helps you along :)

Thanks so much for your advice Ashley. Having a patterned tile is a great idea.

Your countertops are busy, therefore you may want consider a simple tile without pattern. Two busy patterns will not look that great together and will be fighting each other.
