I have an Elddis Odyssey with a rear washroom. The toilet door was difficult to close and open. The problem didn't go away with warmer weather so I had a closer look with a view to curing it once and for all. I found that at the bottom of the wall by the doorframe, on the side adjacent to the shower door there was a small plastic cover, and after levering this off carefully, I found the device which is used to fix the bottom of the frame to the caravan floor. With the movement of the van, this had become slack thus allowing the doorframe to shift slightly but just enough to affect the closure of the door. I slackened off the locking device to free the panel from the floor and then made up a piece of wood slighlty wider than the bottom width of the door frame. I carefully knocked this into place to push the doorframe back into its original place and secured it into position using the turnlock device. Just to be on the safe side I also placed a screw into the floor in the corner of the doorframe to make sure there was no further movement possible.The screw was covered with one of those plastic countersink washers with a clip on cover so that it is not noticeable. The door now closes perfectly. Hope this helps.
