Van Rooyen played Varsity Cup rugby and became one of the 'veterans' of the Tshwane University of Technology side between 2008 and 2011.
The 29-year-old excelled for Pretoria Police Rugby Club and participated in the first ever Community Cup tournament with the team.
He is one of few players to have played amateur rugby and then make the step up directly into the professional game.
The Pretoria-born prop was able to make the transition to Super Rugby with ease in the 2014 season, debuting in a memorable Round 1 triumph over the Cheetahs.
Van Rooyen cemented his starting spot during the 2017 season and represented the Lions in all of their 17 Super Rugby matches as the Johannesburg-based side topped the standings and made their way to the final.
Ahead of the 2018 season, van Rooyen has 49 Super Rugby caps to his name since his debut in 2014.
Van Rooyen helped the Lions to their third Super Rugby Final in as many years before announcing that he would be joining Bath ahead of the 2018/19 season.
He joins Bath having made 66 appearances for the Lions and will provide his side extra depth with his ability to play on either side of the scrum.
