Don't know about the Jetsetter specifically, however, I ran mine on the side, (factory plugs) which are about 6" above the deck. All you see there is a right angle pull box and the conduit goes thru the floor. If you run it up thru the bottom, your tub is 'locked in" to one specific location. You cannot move tub unless you lift it off of the conduit head. It also breaches the bottom pan. If you have a water leak, most likely it will leak down the conduit. Can't speak for all bottom pans, but mine is about 5" tall, or 1" below my power feed.
