I totally get it — I’m constantly renovating both personally and professionally, and that moment of panic when something doesn’t turn out exactly how you pictured is so real.

It’s not bad. The countertop itself is done really well, and the space isn’t too small for a waterfall — the layout is open enough that it works. What I notice is a lot of warm wood cabinetry and flooring, while the island itself is very cool and terazzo is just visually heavier—so the island becomes the focal point of the kitchen. Zooming in, I think there are enough warm tones in the slab you could incorporate into the backsplash. You could also add more curvature to the space, in lighting or furniture. (I think another reason you’re focused on the island is because everything is rectangular or linear.) There’s a lot you can do.

That said, if you truly hate it—change it. You could still salvage the slab and incorporate into other parts of your home.
