I decided to remove the shower as there was a lot of water damage and I worried about the subfloor. the entire stall came out in two big pieces of fiberglass. unfortunately streamline did not think it was necessary to put aluminum paneling behind the front or back pieces of fiberglass in the trailer. I will probably put in a new sheet or just put the new shower in the same location. I also started removing the screens to all of the windows and wall paneling so that I could vacuum behind them, so much mouse activity! I have decided to remove all of the side paneling and floors. I will either put new sheeting on the walls or reuse some that I have taken from the interior as well as put in a new hardwood floor.
