That is definitely the best way to make sure. Giving them lots of things to chew on also help tremendously. Other than that I say just keep an eye on them, if they find an edge and start gnawing you will have to keep an eye on that area.
Otherwise tubs should work fine. I've seen rats and hamsters kept in plastic bins with no problem. Large petstores do it all the time.
