Debit organised for bathroom fitting (5)
I believe the answer is:
bidet
'bathroom fitting' is the definition.
(I've seen this before)
'debit organised' is the wordplay.
'organised' is an anagram indicator.
'debit' with letters rearranged gives 'BIDET'.
'for' is the link.
(Other definitions for bidet that I've seen before include "Type of basin" , "where privates get soaked" , "Low basin for washing private parts" , "Bathroom fixture" , "Bathroom appliance" .)
