With no drawers in our apartment, I had to come up with an alternative. Originally I planned to add the drawer to the BEKVAM cart just below it, but it was going to look ugly and there was all this space under the top which was going to waste. So I removed one of the faces, and modified the brackets to allow an 18" x 12" RATIONELL drawer to be installed. The bonus was I go to re-use the face of the cart as the face of the drawer. This took me 3 days, with the bulk of the work being done in 1 evening. 6-8 hours max.
Step 1Remove the top and one side. of the cart.
I started with an assembled BEKVAM cart. So I had to go back and remove two brackets and the bolts from one side of the cart. I used the wider side for where I was placing the RATIONELL drawer.
