I feel your pain! I have a 2003 Sunova and the shower is just big enough. You have to "plan" how you're going to reach down and wash your foot! Mine is built up off the floor about 6 inches. I've got room for a larger shower but it would be a good bit of work and you'd have to think about how you're going to get a "one Piece" shower in the door. Might have to come in through the windshield and then you still have to get it back the hall so I'd say a "one piece" is not an option. I'm going to live with mine. As I get older I'm starting to weight in the "work factor" when I think about "mods" more than I used to. With a 6 gallon water heater, in a part time home, I really don't spend a lot of my life in there.
