When you are remodeling your bathroom, you may want to remove the toothbrush holder from the wall. You might decide to put up a new toothbrush holder or reuse the one you removed. Whether the toothbrush holder is a tile-mounted model or a unit that is screwed into the wall, it usually is possible to remove the toothbrush holder without damaging the holder or the wall.
Locate the screws securing the toothbrush holder to the wall. Look for screws that typically are located at each corner of the mounting plate.
Remove the mounting-plate screws with the appropriate screwdriver; most screw-mounted toothbrush holders are held in place with Phillips screws.
Pull on the toothbrush holder gently to remove it from the wall. The toothbrush holder may come off the wall without having to pull it, especially if the unit hasn't been mounted for an extended period of time.
Soften the grout around the toothbrush holder with a hair dryer. Cut the softened grout away from the holder with a sharp utility knife. Get out as much of the grout as possible so removing the unit will be easier.
Slide a putty knife under the toothbrush holder; this may take some force because some grout may remain around the holder.
Move the putty knife around the toothbrush holder, prying it up slightly as you go. Work the putty knife around the edges of the toothbrush holder until you can't get the knife under it any farther.
Rock the toothbrush holder up and down until it comes off the wall. This may tear off the top layer of the wallboard paper, but shouldn't damage the wall.
