I am making concrete counters for a bar. I am thinking of integrating a sink in the counter out the same concrete to have one continous surface. Anyone have any luck with this? I am wondering how it holds up with the water usage. Obviously, it would need to be sealed.
I was thinking of using a tuperware container as the mold for my sink (visible side) and then building a box for the underside out of melamine mdf. The other option I was considering was using pieces of the tube they sell to make posts with concrete. I am looking for a round sink around 12" or rectangular of 14x8 or somewhere around there.
