We may get a lot out of it in the bathroom! (5)
I believe the answer is:
towel
'we may get a lot out' is the definition.
I can't judge whether this defines the answer.
'it in the bathroom' is the wordplay.
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'in' indicates putting letters inside.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'bathroom' becomes 'owl' (I am not sure about this - if you are sure you should believe this answer much more).
't'+'owl'='towl'
'e' going within 'towl' is 'TOWEL'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for towel that I've seen before include "Dryer" , "Bathroom cloth" , "Drier" , "This could dry up" , "Bathroom item" .)
