A grab bar assembly includes a grab bar, a mounting flange and an annular cover. A connective block with a bolt hole thereof is fixed on inner side of an end surface of the grab bar. An axial columnar projection with a central insertion hole is arranged on the mounting flange. The central insertion hole forms a countersunk end on the bottom of the mounting flange. When being assembled, the end surface of the grab bar connects with the columnar projection of the mounting flange. An inner hexagonal countersunk screw inserts through the central insertion hole from the countersunk end on the bottom of the mounting flange and threads into the bolt hole of the connective block on the end surface of the grab bar so as to fasten the grab bar with the mounting flange. Then the annular cover is assembled with the mounting flange by the inner thread threaded with the outer thread so as to make the annular cover fix on the mounting flange firmly and shield the mounting flange.
