Surfaced from bathe, any number having sunk (5)
I believe the answer is:
risen
'surfaced' is the definition.
('rise' can be a synonym of 'surface')
I don't understand the remainder of the clue.
(Other definitions for risen that I've seen before include "Grown up" , "mounted a rebellion" , "stirred" , "Sprung up" , "Resin (anag.)" .)
