shower wall

Is the shower wall being held in with plastic rivets? ( A white or colored "head" on the wall about a little smaller than a quarter?)

If so, you can get a few at Lowes or Home Depot. Drill a 1/4 inch hole, insert rivet, hit gently with a hammer to drive the "stem" in flush,and you are done. It is very easy and will look like it is "factory."

Be careful of depth when drilling. A campers wife I know drilled three holes through the shower wall then camper wall and right outside! :)

No doubt your camper has now been through a few winters. Our last camper shower / tub surround was installed in screws. Second or third year we owned it, we had a very harsh winter. The extreme cold caused the plastic surround to shrink slightly. Well, screws have no "give" at all, and something had to "give." It did, the surround cracked. We never replaced the surround. I just puttied the crack and pumped liquid nails behind the cracked area to help seal it. Fortunate, it was near the top, so water behind the surround was not a serious problem.

My suggestion, Liquid Nails, no screws for the same reason. Liquid Nails does have some flexibility to it, even after it dries completely, which will also expand and contract witsh the heat and cold of the seasons. You don't need to use a lot, just the edges, and you'll be good.

I was thinking the same thing, guess that will have to do the trick.

Pump in plenty of Liquid Gold, and temporary duck tape the edge until dry.
