Arrange debit for a bathroom item (5)
I believe the answer is:
bidet
'a bathroom item' is the definition.
(I've seen this before)
'arrange debit' is the wordplay.
'arrange' indicates an anagram.
'debit' with letters rearranged gives 'BIDET'.
'for' acts as a link.
(Other definitions for bidet that I've seen before include "Stay behind" , "Bathroom feature" , "Where to wash" , "Bathroom fixture" , "Bathroom fitment" .)
