The shelves are nice enough but the installation has been a nightmare. The instructions on the Wayfair site contain no specs, specifically what size drill bit I might need to install the anchors that come with it. I used the link provided on Wayfair to contact the manufacturer to find out, and the first e-mail I got back just included the same instructions from the Wayfair site. When I e-mailed the manufacturer again and asked for specs, the rep gave me a recommendation, but as soon as I saw the bit when I picked it up at the hardware store, I realized it was way too big.  I then tried to guess with the help of the hardware store employee, and now I have 5 holes in the wall of my rental bathroom that are still too big and won’t hold the shelf securely. Why is it so hard to get accurate information about how to install this?
