The hosts, who won the trophy in 1997, 2005 and 2009, reached the final courtesy of their 2-1 win over Uruguay in the semi-finals.
Spain secured their place in the final by beating Italy in a penalty shootout on Thursday evening.
The world and European champions are yet to win the Confederations Cup but they have improved on the third-placed finish they achieved in South Africa four years ago.
Vicente del Bosque may be tempted into making changes to his Spain side after their extra-time and penalty exploits against the Italians.
