The Tower of Waters (Japanese: みずの塔Tower of Water) is a landmark on the Isle of Armor in the Galarregion. It is one of the Towers of Two Fists, and it is where the player goes during The Isle of Armor Expansion Pass if they wish to evolve their Kubfu into a Rapid Strike StyleUrshifu. This can be achieved by defeating all the Trainers in the tower and having Kubfu examine the Scroll of Waters on the top floor. The player is only allowed to enter the tower if Kubfu is the only Pokémon in their party. However, if the player doesn't have Kubfu in their party or Box, they can climb the tower with any Pokémon.
If the player chooses to train Kubfu here, the Tower of Darkness becomes inaccessible to them.
The Tower of Waters first appeared in PASS35. When Henry's training with Kubfu was coming to a close, he allowed it to choose which tower it wanted to go to. As it had previously been defeated by an Urshifu guarding the Tower of Darkness, Kubfu chose the Tower of Waters. Battling his way through the four Master Dojo Students inside the tower, Henry was able to reach Mustard on the top floor. Much to Kubfu's fright, Mustard's Pokémon was the same Single Strike Style Urshifu that had previously defeated it.
In PASS36, Henry battled against Mustard and his Urshifu. This time around, Kubfu was able to defeat Urshifu, completing its training. It was then allowed to inspect the Scroll of Waters, causing it to evolve into Rapid Strike StyleUrshifu. As Henry subsequently left the tower, Mustard allowed him to take the newly evolved Urshifu with him, officially making it one of Henry's Pokémon.
