If you are referring to the grab bar, most of them are inserted into holes on either side of the redess and then fiberglassed in. If that is the way yours is installed, then it is not removable, or at least not easily removed nor replaced.: What product can be used to loosen the adhesive and : remove the support bar in a shower/bathtub : combination? I want to replace a chrome bar with a : brass one. The shower/bathtub is made of fiberglass. : Also what product should be used on the replacement? : (Epoxy??)
