There's really not a whole lot to say about this project. The only thing I did that I'm "proud" of is I took the time to cut dados to help with both structural integrity as well as to hold the wood in place to prevent warping. 

Just because I enjoy pain, and dislike visible hardware, I mortise and tenoned the connecting pieces

Boat cleats installed to hang towels and wet clothes 

Added shelves on three of the four corners to add integrity and strength and to provide shelves for haircare (dog and human) and a seat to wash the dogs
