Assembly was pretty time-consuming so expect about 1.5-2 hours depending on your level of perfection/skill (most of it was cleaning cheap Styrofoam off, adjusting the doors/hinges, aligning the hinges and feet which both don't have pre-drilled holes except one part of the hinge). I chose to push the feet in a few inches from the corners to give more of a floating look. The finished product looks great and does a great job of keeping the smell inside.
