ATIS listed moderate icing from 8000 - 12000 ft. on approach into DEN. There was one PIREP we heard on the radio confirming 'moderate mixed icing.' We were put on a downwind vector at 10000 ft. for approach to 34R. In retrospect; we should have asked to stay higher; but at that point; we maybe had a half inch of ice on the nut - windshield wiper - as we turned onto the base leg. Unfortunately; it was a long downwind; so final was just as long; and it was here we seemed to pick up more ice; probably another inch on the nut. We were descending fine on glide slope; and discussed the feel of the plane - no shuddering or vibration; and the engines seemed normal. We landed without event and taxied to the gate with flaps at 15; and then called Operations for an inspection. It was on the post flight walk around that we saw the full extent of the icing event.
Air carrier First Officer reported flying in known icing conditions; resulting in airframe ice accretion.
