I worked on my bar tonight and installed a sink, complete with drain. Here is a picture of the sink with the water running just to prove that it works.
Here is a picture of the "main prep" area that I tiled and grouted.
As you can see, my work area is a bit messy. That's because I have not taken the time to clean. Time is too valuable right now to clean. I need to get ready for the new semester that starts on Monday. Obviously, that's been my #1 priority.
Also, sitting in my garage, I have all of the plywood and oak veneer I need to nearly finish the beast. After that comes trim, but that is only cosmetic.
