I am in home-design heaven looking at these concrete countertops by Get Real Surfaces. I especially love the potting bench. It's my favourite image on their entire site.
And this kitchen countertop/farmhouse sink (also by Get Real Surfaces) looks like something I envision installing in our laundry room. Well...actually...could see S-Boy installing it in our laundry room. Room Service Decorating 101 just posted some great step-by-step pictures of a concrete countertop installation. And for more inspiration check out the excellent books and website of Fu-Tung Cheng Master Concrete Designer.
