The outside shower seemed useless to me. I was looking for a way to make it a water faucet, because I always set up a table under that area. Attached here you should see a pic of this awesome mod.
To purchase one you'll find it here: Spray-Away - DW Inc.
I had to file the holes in the box just a bit to fit the faucet, but otherwise the simplest of installations. It works just fine. I keep the flexspout right in the box. I think the whole thing cost me $60. Now I am still looking for the right set up for a portable sink. I'll post a pic of it all set up next month when I use it for the first time.
I hope this is helpful to someone.
