Solidly built deep sink (8)

Ross

I believe the answer is:

thickset

'solidly built' is the definition.
(I've seen this before)

'deep sink' is the wordplay.
'deep' becomes 'thick' (similar in meaning).
'sink' becomes 'set' (setting is a kind of sinking).
'thick'+'set'='THICKSET'

(Other definitions for thickset that I've seen before include "squat" , "Concentrated" , "Beefy" , "Compact" , "sturdy" .)

I've seen this clue in The Guardian.
