Debit arranged for porcelain fitting (5)
I believe the answer is:
bidet
'porcelain fitting' is the definition.
'bidet' can be an answer for 'fitting' (bathroom fitting). I am not sure about the 'porcelain' bit.
'debit arranged' is the wordplay.
'arranged' is an anagram indicator.
'debit' with letters rearranged gives 'BIDET'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for bidet that I've seen before include "Bathroom fixture" , "Cleaning vessel for privates" , "Type of basin" , "bathroom accessory" , "bathroom installation" .)
