Sid up right in Bath finds trouble (7)
I believe the answer is:
disturb
'trouble' is the definition.
(I know that trouble can be written as disturb)
'sid up right in bath' is the wordplay.
'up' is a reversal indicator (in down clue: letters go upwards).
'right' becomes 'r' (abbreviation).
'in' indicates putting letters inside.
'bath' becomes 'tub' (synonyms).
'sid' written backwards gives 'dis'.
'r' placed within 'tub' is 'turb'.
'dis'+'turb'='DISTURB'
'finds' acts as a link.
(Other definitions for disturb that I've seen before include "Unsettle, discomfit" , "Interrupt; upset" , "Ruffle - worry" , "Interrupt (sleep)" , "Agitate - ruffle - trouble" .)
