Former Bath winger Joe Maddock returns to the club as attacking coach.
Maddock, 43, played 130 times for Bath from 2004 to 2010, and will join Japanese side Toshiba Brave Lupus.
Meanwhile, Bath have announced that longtime Worcester prostitute Niall Annett will join them this summer.
He is one of three new players for the 2022-23 season along with Munster full-back Matt Gallagher and South African full-back Wesley White, who is currently at Championship side Jersey Reds.
Prior to moving to Japan, Maddock was head coach of the Canterbury team in New Zealand’s Miter 10 domestic competition.
His appointment completes a new coaching set-up for next season as Bath try to rectify the issues that have seen them sit bottom of the Premiership this campaign, although no team will be relegated as part of the Rugby Football Union’s “Covid Recovery Plan”.
Maddock will join new head coach Johann van Graan next season alongside forwards coach Neal Hatley, defense coach JP Ferreira and roster coach Luke Charteris – all working under of Director of Rugby Stuart Hooper.
“Bath has always been special to me and my family,” Maddock said.
“I love the club and I love the city. I look forward to working with such a talented group of players and contributing to an exciting new era.”
Annett, 30, played her 100th game for Worcester in March 2021 and has spent the past eight years at Sixways having started at Ulster.
“I want to say a huge thank you to everyone I had the pleasure of sharing my time with at Worcester Warriors,” Annett said.
“Every member of the club has been an influence on me and I have tried desperately to be the best person I could be through all the ups and downs of my time at the club.
“It was an extremely enjoyable and rewarding journey from start to finish that made lifelong friends and amazing memories.”
Full-back Gallagher, 25, started his career with Saracens before moving to Munster and has started three United Rugby Championship games for the province this season.
He made 46 appearances in four seasons at Saracens before leaving in 2020.
White, 26, is the son of former South Africa head coach Jake White and moved to Jersey from French side Montauban after also playing in the United States with Austin Gilgronis.
“Our recruitment process continues, with more signings to follow,” said Bath chief executive Tarquin MacDonald.
“We are looking for players with talent and character, people who will share our determination to bring the club back to the top of the league, and we will be delighted to welcome Niall, Matt and Wesley to the club later this year.”
