Bath have been boosted by news that David Wilson, Stuart Hooper, Nathan Catt and Andy Beattie have all agreed new contracts at the club.
England prop Wilson and former Leeds lock Hooper have signed three-year contracts, while rising front-rower Catt has committed for a further two seasons.
Beattie, now 32, will extend his stay at The Rec to a decade after agreeing a 12-month deal.
"We are very pleased that these players have signed to stay with us," said coach Steve Meehan told the club's official site.
"They are all integral members of the squad and provide us with continuity and growth. They have a lot more to give in a Bath shirt."
