Debit arranged for bathroom fixture (5)
I believe the answer is:
bidet
'for bathroom fixture' is the definition.
(I've seen this in another clue)
'debit arranged' is the wordplay.
'arranged' indicates anagramming the letters (letters rearranged).
'debit' is an anagram of 'BIDET'.
(Other definitions for bidet that I've seen before include "Bathroom item" , "where privates get soaked" , "Type of basin" , "Bathroom appliance" , "bathroom cleaner" .)
