Scrounge from, to get something for the bathroom (6)
I believe the answer is:
sponge
'scrounge' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for sponge that I've seen before include "No pegs on this substance to soak up" , "Wipe" , "Light cake; sea creature" , "that lives in the sea" , "Soft, absorbent material used for washing" .)
