To add more shelf storage, I added a two level, metal sliding shelf under the sink. I removed the block under the sink to see how much work it was going to be to remove the bottom flimsy base to see how much work it's going to be to put a couple of 2x4s underneath to give it more stability. I looked and there is a 3/8" piece of plywood underneath. Nice! So, it took me less than 30 minutes to get it mounted. Works great!
