Is there anything more annoying in a bathroom than a towel bar unable to do its only job? As it dangles by one end, off the wall, it is good for nothing and certainly not for hanging a towel. The problem is the hardware fastener no longer works and is pulled out of the wallboard which can be a self-inflicted wound when someone mistakenly took it for a grab bar once too often.
Unfortunately, when the bar pulled away from the wall it created a hole in the wall so the job gets more complicated. You have to first remove the bar and repair the wall, and then reinstall the towel bar with new fasteners. If the wall was painted it can be repainted, but if there’s damaged wallpaper, you may have to install new wallpaper throughout the room and then reinstall the towel bar. None of these steps are rocket science, but they involve several of them….
