A few before photos to refresh your memory:
First, we had to tear out all the drywall above the stove so we could screw the bar top into the wall.
To get the drill into such a tight space, Zach used a right angle drill attachment. He attached the bar top to the wall studs using deck screws.
For added support, we mounted wood brackets (which I primed and painted white) on to the other side of the wall, below the bar.
