I needed a slim unit to store extra items between the vanity and toilet in my ensuite washroom. I purchased this because not only does it look great but it fits the size of the area desired. Assembly was NOT hard at all, in fact it was very easy - the problem I encountered was that although 1 extra piece of hardware was included for each hardware required, one of the bolts cracked and it got stuck in the unit and I couldn't get it out. Also, as I was tightening the bolt (no power tools), I noticed one of the brackets cracked. I had to use white electrical tape to hold it together otherwise the shelves won't hold right. I have to anchor this to the wall which I didn't realize when I purchased it as it clearly warns that this item MUST be anchored to the wall for it to be deemed sturdy. I wish I could return it now. The inside drawer measurements are: 9.5 inches (left to right width), 9.75 inches length (from back to front panel) and 8 inches from base of drawer to top. It's not that sturdy, but it works and looks nice. I suggest to use the wall anchor to make sure it doesn't tip over (it will). I don't have heavy items in there, light items (extra toothbrushes, toothpaste, toiletries).
