Thats pretty much what hes doing, right? Except it's into the counter. Honestly, its stupid. Not portable, not waterproof, etc. Im assuming this guy has a big countertop so he has the room to put it there without being in the way? Do this: Build a bartop one and then put a few small holes or square brackets into the bottom so it can be mounted. If you use square brackets, in the shape of an L, you can place the bottom under the counter, drill it through the counter, and attach it on top to the bartop.
