Defending champions Sliema will have the opportunity to retain the title they won last season after securing another place in the championship final.
In the semi-final played on Friday at Pretty Bay in Birżebbuġa, they defeated Spartans 8-5 in a highly competitive and closely contested match.
The Slimiżi were determined to book their place in the decider, although Spartans also put in a strong performance in an entertaining encounter that remained open until the closing stages.
Sliema will now face La Playa de Arena, who produced an upset by eliminating Ħamrun Beach Soccer 9-7.
At the end of regular time, the score was tied at 5-5, with the match eventually being decided by a penalty shoot-out.
The final between La Playa de Arena and Sliema Beach Soccer will be played on Monday, kick-off at 20:30.
