A multi-functional adjustable umbrella base includes a base support, a reinforcing support adapted for being mounted onto a spa bathtub or a platform near a spa's edge, and a stem rotary arrangement supported by the base support for selectively rotating the supporting stem of an spa umbrella and for securely locking up any of its movement. The stem rotary arrangement includes an engaging member rotatably supported by the base support and coaxially connected to the supporting stem of the outdoor umbrella so as to selectively rotate the stem of the outdoor umbrella, a locking member connected to the engaging member for selectively locking the engaging member from being rotated, a paddle operatively connected to the locking member via a connecting arm, and a resilient element mounted on the base support and adapted for normally applying an urging force to the connecting member. In order to unlock the locking member, one has to step down the paddle in order to lift up the engaging portion of the locking member so as to disengage it from the engaging member. Then, the user can ready to rotate the supporting stem of the spa umbrella to a desired orientation.
