Drunk bathes in drink (8)
I believe the answer is:
absinthe
'drink' is the definition.
(absinthe is a kind of drink)
'drunk bathes in' is the wordplay.
'drunk' indicates anagramming the letters.
'bathes'+'in'='bathesin'
'bathesin' anagrammed gives 'ABSINTHE'.
(Other definitions for absinthe that I've seen before include "intoxicant" , "Aniseed-flavoured liqueur" , "Green wormwood drink" , "Strong liquour in the basin?" , "Potent green gin-type liquor - wormwood" .)
