I am updating this edit. After all the extra work to get this installed we discovered that it has a hole in the inside that drains straight out into the back. There is no way to plug it up from the inside . Plugging from the outside/back would mean that you would always have standing water on the inside of the sink. I have not yet contacted wayfair about how to deal with this. We just discovered it. I will update this post.

OLD: It's a great sink. We're happy with it. There was nothing else like it and I searched for a long time. But it is VERY hard to install. The back is mostly closed and doesn't allow room for internal plumbing. Out contractor had to cut the back of the sink with a specialized saw. If you don't have this tool you may be forced to return it or position it a good distance away from the wall.
