European bath with rotating plughole (8)
I believe the answer is:
spaniard
'european' is the definition.
(Spaniard is an example)
'bath with rotating plughole' is the wordplay.
'bath' becomes 'spa' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'rotating' shows that the letters should be reversed in order.
'plughole' becomes 'drain'.
'drain' in reverse letter order is 'niard'.
'spa'+'niard'='SPANIARD'
(Other definitions for spaniard that I've seen before include "Eg, a native of Madrid" , "Person from Eurozone" , "Slope-measuring instrument" , "A native of Iberian country" , "Native of southern European country" .)
