When my Ikea look-alike floor-standing “organizer” suffered trenchfoot after a toilet flooding incident and collapsed, I built this cabinet out of poplar and hardboard “bead board”. It hangs on the wall with a French cleat and one screw to secure it from jumping off the cleat. I finished it with an off-white interior enamel sprayed on in two coats. I also re-faced the vanity cabinet with the same doors and drawer fronts.
I measured it twice, cut it twice, and it is still too short!
