Hafþór began his sports career as a basketball player. At 2.06 m (6 ft 9 in)[2] he started his senior team career with Division I club Breiðablik in 2004. In 2005 he joined FSu Selfoss in the Icelandic Division I. After 10 games it was discovered that he had been playing with a broken bone in his ankle and would require surgery. After recovering from surgery, Hafþór moved to Úrvalsdeild powerhouse KR in 2006.[3] He missed most of the 2006-2007 season after a screw in his ankle shattered and had to be fixed by another surgery.[4]

For the 2007–2008 season, he moved back to play for FSu Selfoss. For the season he averaged 6.7 points on 63.8% shooting,[5] helping the team achieve promotion to the Úrvalsdeild.[6] The troublesome ankle forced him to retire from basketball after the season at the age of 20.[7][8]

Between 2004 and 2006 Hafþór played 32 games for the Icelandic junior national basketball teams.[9] In 2006 he played 8 games with Iceland's U-18 national team in Division A of the U18 European Championship.[10]
