I am building a bar at home and would like to mount a 5 Faucet T Tower into the rear bar top. My plan is to put the chest freezer on the other side of the wall, drill a hole through the wall and then run the lines from the freezer, through the wall, to the tower.
My question is this: Since I do not need a collar for taps, do I just drill a hole in the top of the freezer to run the lines out? What should I insulate it with? Any other ideas?
