Bath scrubber (6)
I believe the answer is:
loofah
'bath scrubber' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for loofah that I've seen before include "Part of fruit used as bath sponge" , "Kind of bathroom sponge for rubbing back" , "cleaner" , "Bath sponge made from dried plant fibres" , "Bathroom sponge for washing back" .)
