Six years ago I built a 4'x5' concrete counter top for a kitchen island that I built. I somehow forgot the pain and what a complex process the whole affair was. So this summer I decided to replace all of our kitchen counter tops with polished concrete tops that match our island top.
This section has a under counter mounted sink. A sink pop-out is incorporated in the mold.
The pop-out is positioned and secured in the 3/4" melamine mold. All of the inside corners are sealed with silicone.
3/8" rebar is used for strength. The concrete will be a 2 1/2" pour! How could anyone afford to have this done? Just buy granite!
