The under-the-sink area can be pretty dreadful. It's cramped and hard to keep tidy — which is also why it's the perfect spot to install a pull-out drawer.
This dark hole (or is that just my kitchen?) deserves better. Stuff falls over, things gets pushed to the back. Out of sight, out of mind.
But a pull-out drawer — relatively easy to install and inexpensive — could change all that. You could still separate items into bins, but this way you won't have to reach into the depths to find them. Save your back and your sanity.
