I had created a free standing masonry wall that I used for this outdoor kitchen. I then placed a solid polygon on top for a countertop. One of my problems is I can't figure out how to put a hole where the sink is and I have a feeling this should be a simple process. Also, I would have used cabinets in place of the free standing stone but didn't think I could change the surface other than color. Possibly I could have put cabinets inside the masonry and created the countertop in that manner. Thoughts?
