Massaging bath (7)
I believe the answer is:
jacuzzi
'massaging bath' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for jacuzzi that I've seen before include "Whirlpool bathtub with underwater jets" , "Modern bath with underwater jets" , "Whirlpool bath" , "Bath with water jets" , "Type of bathtub" .)
