She had a total length of {{convert|36.90|m|ftin|abbr=on}}, a beam of {{convert|4.37|m|ftin|abbr=on}}, and a draught of {{convert|3.69|m|ftin|abbr=on}}. The submarine was powered by two Benz six-cylinder diesel engines producing a total {{convert|270|PS|shp kW}}, two Siemens-Schuckert electric motors producing {{convert|280|PS|kW shp}}, and one propeller shaft. She was capable of operating at depths of up to {{convert|50|m}}.{{sfn|Gröner|1991|pp=23-25}} The submarine had a maximum surface speed of {{convert|9.06|kn}} and a maximum submerged speed of {{convert|5.71|kn}}. When submerged, she could operate for {{convert|45|nmi}} at {{convert|4|kn}}; when surfaced, she could travel {{convert|7030|nmi}} at {{convert|5|kn}}. UB-32 was fitted with two {{convert|50|cm}} torpedo tubes, four torpedoes, and one {{convert|8.8|cm|in|sp=us|abbr=on}} Uk L/30 deck gun.
