I salvaged a beat-up, old kitchen cabinet from a construction site and used it to make this concrete planter on wheels. This is a simple project that requires some heavy lifting. I used 2” thick XPS rigid foam boards to make the inside of the form. Heavy duty metal casters and a chrome spigot make it easy to move and drain, while providing a fun industrial aesthetic. Use it as a mobile herb garden or fill it full of ice and beer for your next party.
