This is my workspace.  The two pipes with the faucets are for controlling the hot and cold water access to the tub.  The small piece of metal attached to the top of the tub is from the original overflow outlet system.  The catch pipe is below the tub and out of picture.  You can see some of the dirt that I had to dig out in order to expose the catch pipe.
