I think the important question to ask is how do you build a bar and have room for ONLY 6-8 bottles?
I didn't build it, now moved in and I have room for 8-10 on the top (floating) shelf and more than I'll buy in other areas of the bar. I do have some work to do on it. I've found that the floating shelf is loose and was not installed properly so I'm not putting good booze on it for fear of it falling down.
