Something that has always bothered me since buying our RV new 2 years ago is the gap between the bottom of the shower walls and the pan. I can't tell if there's a decent overlap (the pan edge extending up behind the wall).
I've considered running a bead of silicone around there to seal it, but not sure it's intentionally left unsealed by design. What I don't want is to discover a few years from now that - due to that gap - water has been wicking behind the wall and under the pan.
Any opinions/suggestions from experience welcome!
