One displaying bathroom feature (6)
I believe the answer is:
shower
'one displaying' is the definition.
(someone displaying or showing things)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for shower that I've seen before include "One who indicates way" , "that's revealing?" , "Short period of rain" , "Pelt" , "worthless group of people?" .)
