i’ve been wanting this shelf for quite some time and finally decided I’m doing it. I’m absolutely completely satisfied with the size the quality of the wood and the paint job. It’s made very well. I have to say I was surprised at how nicely sanded it was and ready to hang.

Easy install
Just installed in our bathroom. Feels solid. We have a potted plant on it now. You will want a drill bit extender to clear the shelf. I use the flexible type. Otherwise you won’t be able to get the screws in at a 90 degree angle.

Very nice, well made.
The nine-inch oak shelf is well made, and is 45 degrees. The wall where I planned to install it was not, and I suspect this is the problem some of the reviews saying the shelf was not made at 45 degrees. In my case, we removed wood a bit at a time until we achieved a good fit. We did receive all of the hardware, but beware. The plastic straight insert anchors do not snug up with the supplied screws. However we used the supplied plastic toggles with better results. The hardware is why I rate this 4 stars. Otherwise, it is a nice piece, and well worth the price.
