I recently posted a picture of my coffee bar in my home and received a lot "likes" and comments so I thought that I would show where I purchased the supplies to create the coffee bar.
For the piping mounted under the bottom shelf: https://www.lowes.com/pd/Southland-Pipe-3-4-in-x-2-ft-150-PSI-Black-Iron-Pipe/3371438
You’ll need 1 two-foot pipe, 2 elbows (90 degree iron elbow fitting) 2 two inch pieces with threading on both ends, and 2 pieces to mount it to the bottom of the shelf: https://www.lowes.com/pd/Mueller-Proline-1-in-dia-Black-Iron-Floor-Flange-Fitting/50276203
I sanded the piping after I put it all together and spray painted it black using Rustoleum Hammered Black paint.
