This may be a re-inventing the wheel type thing, but I recently ran across a 50 gallon compressed foam stock tank by Rubbermaid at a local DIY store. It is 31" wide, 50" long, and about 13" deep, perfect for a hermann's tortoise, russian, greek, etc. I built my own wooden pens (roughly the same size) but I've always worried about disinfecting. These stock tanks solve that problem completely. Anyway, I'm really excited, thought I'd share it. They're about $50, and I'm slowly but surely replacing my other pens with these for convenient winter keeping.
