Designing Kitchens and Bathrooms - Rock hard wallpaper in tight space ???

I'm kind of stuck on how to proceed. I removed all the wallpaper in a small bathroom except for two area's. The area is between the shower and corner - and - the entrance door trim and wall. Both are very narrow and the "THREE" layers of wallpaper are petrified to the sheetrock.

Any ideas what I could do?

The wallpaper on the "metal outer edge" of the shower is rock hard also. I'm thinking maybe I can dremel it down to where I can just float some mud over it and be happy.

I've got pictures if they'd help but nowhere to post them.

Welcome to the forums!

It is always best to remove all the wallpaper! If it isn't feasable, coat the offending paper with pigmented shellac [will seal it and prevent it from lifting] and cover the area with joint compound when dry.
