It did not reach the ceiling. It was secured to the floor and the left wall.

Thank you! what did you use to secure it to the floor? I have laminate flooring where I want to place a room divider, similar to creating a mud area and create some separation from the entrance door and living room. I was going to secure it to the wall to the left but I am worried about the side where there is no wall. Any tips/videos would be very much appreciated!

Lisa the installers usually use L brackets to secure to the floor hidden behind the toe kick. I don't have any videos but a good licensed and insured cabinetry contractor should be able to build and install and warranty the product for you.
