CB Tormes was founded in March 2000, after splitting from UD Santa Marta, that created the basketball section in 1998.

During all its existence, the club was alternating Liga EBA and Primera División, always resigning to the first one by financial inability.

In the 2014–15 season, CB Tormes played a new promotion playoffs, but could not win the stage.

In 2018, CB Tormes signed a collaboration agreement with Liga ACB club Baloncesto Fuenlabrada for becoming their reserve team.

With this agreement, the club could achieve one of the new places in LEB Plata, third tier, after its expansion from 16 to 24 teams.
