I think following trends is a waste of time. You're the one who has to live with it. If you like a waterfall benchtop and want to pay for one, have one. If you personally like something else then have that instead. That island pictured is perfectly fine .It's smart to have the overhang that deep, it's actually the same length as the waterfall. If it were cut shorter not only would your feet kick the stools as you walk around the island but it would look unbalanced then with a very obvious short side. You see, some people see the distance from the edge to the cupboard, I see the benchtop and how one end relates to the other. You might be someone like me who has that orientation or like the others who have a different one.

Different perspectives see things differently, that is the beauty of life. If we all thought the same it would be boring.
