I know this is a really old thread but OP, or others, this build is exactly what I'm looking to do. I can't tell whether this was a bought cabinet or totally fashioned from bought wood but call me seriously impressed, and yes, I'd like to hint at a good old English pub bar as well. So OP, if you're still around for some questions, greatly appreciated.
I plan on making enough room inside to house two firkins, whether on stillage or on vertical draw with a widge. I also plan on 2" R13 Rigid foam for insulation everywhere. So these dimensions include room for the insulation, gaps, etc.
Depth, 25", L, 64", H, 37". Plus a 2" solid piece of wood as you have, for the bar top. I have the guts ripped out from a dorm fridge through the kind help from another member, and can figure out how to install them. Curious on yours - seems your compressor is interior, if you have specifics on venting, that would be great. Don't see your coil, also would be great.
I'm also considering just doing a coolbot with a low-btu A/C.
I was planning on a 2x4 skeleton, OSP overall, and perhaps a nice veneer. Or, a more rustic look with antiqued wood as the exterior.
Anyway, just didn't know if you're around. Have found nothing in the way of a piece of cabinetry already there - everything is too shallow for a cask. Frustrating as I can do carpentry, but not that great at it and I'd prefer to convert something ready made - hence my question to you. It does look like you built from scratch, and again, congratulations.
FInal solution is to just keep looking for a reasonable, used back bar cooler and build a bar around it.
