Thats exactly what I do. I use lids on all my tubs. My rack looks alot like this one. There are a few exceptions but all in all its pretty close. I used 2" x 3" for the 4 side posts, 1" x 2" for the side rungs(holds the shelves) and 3/4" MDF for the shelves. I also used 1/4" luan for the back. Its not necessary but it does add stability. I've found it that MDF is much straighter and stronger than any other sheet good out there. It cuts really great. This is a very inexpensive and effective rack build.
