Aaargh wallpaper!!….lucky you only have one room to remove…unlike an entire house full of the stuff we had to remove.  If it is vinyl (which is most likely being in the bathroom), you will first need to remove the vinyl layer with a metal scraper, becaue a steamer will not get through to the paper, then you repeat the process with the steamer…it will be your new BF if you leave it on the wall long enough so the paper literally peels off the wall. Enjoy!
