The Extend-a-shower from Camping World is permanently installed. It works GREAT! My wife loves it. Simple to install. Better than a permanently curved installation in my book because you can collapse it inward and get things out of the way. Also, it can be used to drip dry bathing suits etc. and the water will drip right into the tub.
