Place for a soak (3)
I believe the answer is:
spa
'place for a soak' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for spa that I've seen before include "Water source" , "Watering-place" , "here for the good of his health?" , "Hydromassage facility" , "Health and beauty treatment establishment" .)
