I am so new to this forum that I haven't even taken delivery of our 2017 Viking 17FQ. But my previous Jayco came without a shower surround, and that really worried me, so I added my own. You can get anything on Amazon, including lightweight RV shower surrounds. But watch out for the size since they come in different sizes. It will need trimming with a knife or scissors, as mine took a few "fittings" to get it right before I fastened it in place. The water fittings are easy to undo and reinstall when done. And before fastening the surround to the walls, I added copious amounts of silicone in the corners and cracks, just in case. I used plastic expanding anchors, but I see the factory simply used white screws in my new 17FQ. Did I mention color choices? My new shower is white, and my old one was parchment color. Remember that the colored plastic water fittings ought to match the shower and can be replaced while you have things apart. Good luck with yours.
