Concrete countertops were a short-lived trend in the early 2000s. They are still seen occasionally, though. They are quite porous and even with sealer, can easily be stained. A lot of ambitious DIY types have made attempts to make these countertops for their homes but found it to be a difficult project since costs can add up quickly. If you are looking for the industrial look, you can consider granite with alternate finishes such as brushed or water washed. For a thicker edge, try laminating the edges. There are also quartz surface options that have a similar look.
