The popular edges are, for the most part, practical for any use in the kitchen or bathroom. So the primary factor to consider when you make your edge profile choice is aesthetic. Which do you like the best? Which will compliment your space? If your kitchen is contemporary or industrial, an ogee edge will look out of place with its classic curves, and you’d be serviced better by a half bullnose or a bevel. A country-style kitchen would be enhanced by waterfall edges. And the stair tread or ogee edges would fit nicely in a modern, elegant space.
Do keep in mind, though, that any crease in the edge profile may be a potential trap for food and dust, and the more creases within the edge profile, the more maintenance and cleaning the countertop will require.
Ultimately, you should choose the edge profile that you like the best. GKC has samples for you to look at. Remember that once you buy a natural stone countertop, it will last the rest of your life (and probably your children’s and grandchildren’s lives), so choose the edge that you love, even if it costs a little more. You’ll be glad you did.
