Erika Butkeviciene, 47, and Stella McNulty, 46, attacked Nigel Clarke in his flat in Eastfield Road, Peterborough, in August last year.
They bragged about the killing to fellow drinkers in a city park the following day.
He was last seen alive on August 21, when he was spotted on CCTV walking with Butkeviciene and McNulty. He did not have any visible injuries at that time.
The women told friends they had smashed the 49 year old's head against a radiator before putting him in a cupboard.
Both were jailed for life, Butkeviciene was ordered to serve a minimum of 15 years while McNulty must serve at least 13-and-a half years.
