Reconstructed urinals are a bit narrow (7)
I believe the answer is:
insular
'a bit narrow' is the definition.
'insular' can be an answer for 'narrow' (I've seen this before). I am unsure of the 'a bit' bit.
'reconstructed urinals' is the wordplay.
'reconstructed' is an anagram indicator.
'urinals' anagrammed gives 'INSULAR'.
'are' is the link.
Can you help me to learn more?
(Other definitions for insular that I've seen before include "Surrounded by water - narrow - prejudiced" , "Man may be thus described" , "Detached - urinals (anag)" , "Lacking contact with others" , "Detached from mainstream" .)
