For camping.or tailgate parties.This says: Interesting invention! Now, of course, I'm plotting how to make a period-oid one, with the center compartment being a cooler hider. With a couple more stools this could seat a decent picnic.
I LOVE the design of this "shower deck". It keeps you off the ground and also holds shampoo bottles, etc. I would not put my toiletries in there though. That would be gross to store your tooth brush in something that was on a public shower floor!
