I have one from Home Depot and can't say I'm unhappy. It was a good solution to an expensive repair that has lasted almost a year now. The accordian doors are cheeply made - they may last only a couple of years - but they are light weight, come in a variety of colors, easy to install, cut, mount, and well, if they break can be replaced in 24 months for free with receipt at any Home Depot. I reinforced the holes at the top with grommits and that seems to be the issue with these door for other users. For a little over $20 the door looks great.
Good Luck, your idea sounds great and was what we originally did but with a fabric shower curtain with palm tree print. Worked well.
