I have a 21 BHE 2019 that I bought used last fall. This is the first time we are useing it and noticed some rot comming behind the wall in the shower while showering . The reason and that's why I'm posting is that is I have a 3/16th space between the base of the shower and the wall surrounding the base.
Is the space normal or should ther be caulking to fill that space all arround the base?
Thank you in advance
