This powder room in a contemporary-styled home has wall-mounted handles and faucet that protruded from the wall several inches.
When I first visited the home for an initial consultation, I explained that making “relief cuts” in the wallpaper in order to work around these fixtures would result in lots of slits in the wallpaper … which could be visible, and which also would potentially provide openings that could allow splashed water to wick in behind the wallpaper and cause it to come away from the wall.
The homeowners arranged to have a plumber come in and remove the fixtures.
This allowed me to hang the paper much more easily, and saved me about an hour. But most important, it eliminated all the cuts and slits, and the potential problems mentioned above.
I kept the holes as tight to the plumbing stems as possible, to eliminate any gaps between the wallpaper and the fixtures. When the plumber comes back to reinstall the handles and faucet, if need be, he can easily take a scissors or blade and enlarge the holes a bit.
