Depends on what kind of similar you’re looking for.

Sounds like water? Dire Dire Docks.

Sounds like water but more mysterious? Aquatic Ambience.

More like ice and kinda sad? Schala’s Theme

Solar Fields maybe?

Atlantis from Banjo Tooie gives similar vibes I think

Ruddy mysterious.

I would assume the music from the water temple is similar to the music played 24/7 in hell. lol
