This outdoor bar with a concrete countertop is a sturdy piece of outdoor furniture that serves as a nice place to sit and have a drink or as a food prep island. Concrete countertop slabs are pretty easy to make, but are quite heavy, so I recommend making this project near its final destination. This bar is made from 3 concrete slabs that are bolted and supported by a wall made out of 2x4s. This is one of the more challenging projects I have posted. It’s critical to make sure that the bolts, which are cast into the slabs, are aligned with each other.
