"We've seen some terrific action along the way with some great games," said Ben Rose, WRU Women's Development manager.
"I expect both finals to be even contested. Both teams in the Cup final have played some attractive rugby en route to the final and thoroughly deserve the opportunity to claim the trophy.
"The competition structure allows for all teams to have an opportunity to play in the first round of the Cup with teams who drop out at this stage having a second bite of the cherry in the Plate competition."
