it's not like they need to be inside

I actually didn't think they COULD be placed indoors... Only bare ground, like a campfire. Or is this wrong? (well yeah ok campfires can be indoors... But with ventilation.)

Actually it is quite easy to build one without a stone floor. Just demo the floor where you want it and place it on dirt, then snap floor tiles back in. They will clip right into place.

I even have one in the corner of my base where I also demo'd the adjacent walls and placed it with just the opening in the room, and the stack is still outside. Walls also clip in fine. Works very nicely.
