Would this be to lay it on it's back without the shelves? It does seem a bit shallow, either way, at about 10.5 inches deep. Upright it wouldn't really be deep enough. On it's back it would need extra height (but you could make that with a raised mesh lid, or have two of them - one stuck on top of the other. Which would mean it would cost about $40 plus the materials to make a lid and other bits and pieces. It might work out almost as cheap to have a detolf.
Or you could get a bigger bin maybe. This one is a 50 gallon bin and a good size. It costs $20 but the single units are out of stock online and they are selling 3 for about $60. But they may have single units in stock in a store near you.
