will join Bath for the 2012-13 season and Wasps' former Blues coach Young hopes Thomas will fill the void.
Thomas made his Wales debut in 2005 and won the last of 27 caps in 2008.
"I am really looking forward to linking up with Dai Young again who has been a big influence to me in my career and I'm excited by the challenge of playing in England with London Wasps," Thomas told
the Wasps website.
"Like most professional players I always keep an eye on how the game is going in England and it's the kind of challenge that I know I will relish."
Young, who was a Blues coach for nine years before joining Wasps, added: "I obviously know Rhys very well having coached him for many years, and he will be a real asset to our squad next season.
"He is an experienced international and exactly the kind of quality player we want to bring to the club."
Welsh club rugby is suffering an exodus of players joining rival leagues as the Blues, like Wales' other three regions, have to adjust to operating with a £3.5m salary cap from next season.
Thomas has been at the Blues since the region's formation and advent of regional rugby in Wales in 2003.
The front-rower is the Blues' first-choice hooker and with
