Do you mean a curve on the stool side or sink side? I say curve on stool side for sure. Will give you more elbow room

Want to get rid of the 2end corners.everyone keeps hitting them

Yes on stool side

here is what it the granite looks like. now for backsplash- any ideas?

and flooring. hardwood or vinyl plank?

thinking of this tile?

Hardwood for sure.

I'm not sure if your new granite is siting properly on the cabinets, it looks like you can see the plywood under the edge. I'd get the supplier to inspect the install. In regards to the backspalsh, since the granite has a busy pattern, it would be best to pick a tile that is larger in scale and isn't a busy mosaic. Otherwise you have 2 busy surfaces fighting against each other. But you are headed in the right direction by picking a stone finish that is plain and doesn't have a lot of colour variation. With a dark grout this mosaic backsplash could work. I agree with Carolyn, hardwood is the best option.

Agree that you need a less busy backsplash given the pattern of your granite. It's a pretty granite for the white cabinets. I would suggst a light colored backsplash with matching grout. Hardwood floors.

the trim is all done on the cabinets and island - just not in this picture. thank-you
