The shelf was very simple 48” long, 20” wide enough to fit in the shed and hold the bins. We also made the shelves only 15” high just high enough for them to fit under. The shelf needed to be able to hold a lot of weight so he secured each board with two screws.
The shelf fits perfectly in the shed and so did the storage bins. This will make getting into the tubs so much easier. When the weather cools back down in the fall I’ll ask Jack to make some more for the other sides of the shed and storage bins, he just doesn’t know it yet.
