Fully commit to making a splash? (4,3,6)

Ross

I believe the answer is:

take the plunge

This could be a double definition.

'fully commit' is the first definition.
(taking the plunge means committing to something)

'making a splash?' is the second definition.
I know that 'splash' relates to this answer.

'to' is the link.

(Other definitions for take the plunge that I've seen before include "Summon up courage" , "accept the challenge" , "to leave the board" , "Get married (informal)" , "Resolve to do something irrevocable" .)

I've seen this clue in The Guardian.
