I've been asked to prepare a 3D model for 3D printing in sandstone. I've been told that it needs to be 3" tall and the walls have to be at least 2 mm thick. It's an absolute pain in the neck having to make sure everything is the right thickness. So, I was wondering, can the whole model just be printed as a solid object, with 100% infill, and does that work for sandstone?

Yes, you can just print it solid. However, it might be significantly more expensive to print your object entirely solid. For instance, Shapeways charges $0.75 per cm3 of material for their full color sandstone. A solid cube of 5x5x5 cm would cost $96 to print, whereas it would only cost around $6 if you printed it hollow with 2mm walls.
