How to get electrical to bar in basement build

While that may work the old fashion way is to dig a trench in the concrete and bring the wire from the wall up inside the bar. I rented a mini jackhammer for a 1/2 day an did that for my back bar.

It would be harder to get a perfectly shaped trench at the exact depth you need for your idea than just jacking out a small trench in the concrete, adding PLASTIC conduit and then backfilling the void with fresh concrete (don't forget the acrylic concrete patch binder along the edges of your trench before you pour). At the end of the underground conduit you would have a smooth radius 90 degree tube sticking up and out of the concrete where you need it. From there you can simply attach the romex wiring to your bar studding and run through the cabinetry, code permitting. If it is exposed there is some lightweight electric blue corrugated conduit that is used as a sheathing for the electrical wires. If code requires this in your area, just make sure you get the correct transition pieces to come out of the ground, through the elbow and have your corrugated conduit attached securely to the end of the elbow. If you go to the electrical section and start looking at all the pipes and fittings for this project you will see exactly what I mean.

If jack hammering a floor isnt for you, perhaps putting the bar on a small riser to provide you elevation over the front row of seats, then you could run your electrical through there. Ceiling height permitting.
