Hamilton started against Wales at the Millenium Stadium last weekend while Lawson was a second half replacement.
With the Six Nations taking a break this weekend, they return in the second row and at hooker respectively.
These are the only changes to the starting line up from the side that defeated the Northampton Saints at Kingsholm last weekend.
With Gloucester currently in eighth place in the Aviva Premiership table and Bath just one place behind, there's a lot riding on the game with both clubs striving for an automatic Heineken Cup qualification place.
Throw into the mix that it's likely to be a usual no holds barred West Country derby, and a fascinating game lies in wait at the Rec.
Gloucester have won three of their last four in all competitions and Forwards Coach Carl Hogg admitted that maintaining that run of form is massively important for Gloucester.
"It's obviously a pivotal fixture for both clubs and it's about building that momentum, getting on a winning run and building confidence.
"We've taken a good look at Bath and they appear to have gone back to a base game. They've built an efficient drive and their scrum is coming on. It's going to be a big challenge down there.
"These are always special fixtures, quite unique. We talk a lot about emotional factors but, for us, it's about playing for Gloucester, the jersey, the team. That's paramount.
"If we deliver passion and pride and get some accuracy into what we do, then we should be there and thereabouts."
