SU 5753 is a preparation for a possible cocciopesto floor in southern Area F. It seems to be in phase with wall 5764 because it cleanly abuts it and is not cut by it. On its northern limit it is bordered by block 5769, which could be the remains of another wall. The eastern and southern limits have been disturbed by later concrete features, but SU 5753 seems to have been the floor in the northwestern quadrant of an otherwise unknown room in southern Area F.
