We went from a 32" to a 28" vanity. These sink organizers have allowed for more storage in a more compacted space. It seems like they hold more than expected.They are easy to assemble. Everything in the organizer is easy to see especially the bottom tray since it can slide out.The bars are metal and the shelf and drawer are plastic. The balance can be little skewed depending on how far you shoved the metal bars into the holes. Typical of shelving units, some bars need to go in further than others. I used a rubber mallet and cloth to tap the corners vs. using the force from my hands to balance the equipment. It took a little elbow grease and patience to make it study.I would buy more of these if the pipes and/or garbage disposal wasn't preventing them from fitting.
