You got it! Functional runnels, are usually pitched toward the sink, and we like to make them wide enough for you to put your finger in. We think this makes it easier to clean and the pitch speaks for itself. They should not be rough or square, as that would be hard to clean.
One more thing to note is that many people use them more on a daily for rinsing fruit or vegetables off. Set the colander right over the runnels and the water stays contained within the runnels.
I always say most people buy them for the look (at least I think that way), but they are super functional for a busy life.

Counters with Cherry cabinets. I don't love the backslash, but it does have nice color and looks nice. Maybe a similar colors but smaller or different shape tile.
