Article on uni opening hospital in Bath (5)
I believe the answer is:
sauna
'bath' is the definition.
(I've seen this before)
'article on uni opening hospital' is the wordplay.
'article' becomes 'a' (indefinite article).
'on' is a charade indicator (letters next to each other).
'uni' becomes 'u' (U is an abbreviation for university).
'opening' means one lot of letters goes inside another (some letters open a gap in others).
'hospital' becomes 'san' (I've seen this in other clues).
'u' placed into 'san' is 'saun'.
'a' after 'saun' is 'SAUNA'.
'in' acts as a link.
(Other definitions for sauna that I've seen before include "Sweat room" , "A Scandinavian steam bath" , "Where one is sweaty" , "Very hot room for cleansing, of Finnish origin" , "Finnish-style bath" .)
