Cheryl, It's not uncommon to apply wallpaper over existing wallpaper. However, your liquid paper remover and your efforts to remove the existing paper may have loosened the adhesive and wall-paper backing that remains on the walls. Inspect it very carefully to make sure it is all still sticking. Also, try to remove/scrape off any bumps or rough surfaces; they'll show through most lightweight papers that you're likely to use in a bathroom. It's better to go ahead and remove the rest of the paper and the adhesive from the walls before you paint or apply new paper. The difficulty you had in getting this far suggests to me that you were probably trying to remove a vinyl-faced paper that would not let your liquid remover soak through to the adhesive. That's good news because removing the rest of it will probably be much easier. Get a spray bottle to put your liquid remover in and spray on the walls. Apply to small enough sections so that you can remove the paper in that area before it dries. Be patient and let the liquid remover do the work for you. You'll know it's ready to come off when it peals like a banana when you scrape it with a putty knife. If it doesn't scrape easily, apply more remover and wait some more. Be careful not to gouge the walls. Once you have the paper backing off of the walls use a sponge to remove the adhesive while it's still wet. Hope this helps!
