Grab bar shower holders are a sturdy safety measure against accidental slips in the shower. When replacing the tub or shower walls, it is necessary to remove the grab bar and relocate it later. Removing a grab bar shower holder is a matter of finding the screws securing it to the wall. If toggle bolts are securing the grab bar to the wall, the wings of the bolts will harmlessly fall into the wall cavity.
Place a sheet or towels in the bottom of the shower or tub to protect surfaces while you are working.
Score along the silicone caulk around the outer perimeter of the grab bar mounting plates, using a utility knife.
Find the screws securing the grab bar to the wall. The screws are on the mounting plates against the wall. Some grab bars have a decorative plate over the mounting plate. Look for a small set screw on the outside edge and remove it with an Allen wrench. Slide the decorative plate off the grab bar.
Remove the screws on the lowest mounting plate with a Phillips-head screwdriver or socket wrench, depending on the head type. Hold the centre of the grab bar with one hand, then remove the screws from the upper mounting plate. Pull the grab bar shower holder away from the wall.
Scrape any residual silicone caulk from the wall with a plastic putty knife.
