Reddit mentions of Esschert Design Fire Bucket

I'm a bit late to the discussion, but you got me thinking about this for myself. I did a DIY sauna one time with a friend on a multi day camping trip and it was amazing. It was pretty ghetto seeing as how we used a tarp as the structure, and heated rocks in the fire. We dug a hole in the tarp structure to hold the rocks (the ground was dirt). We stuck the rocks in the fire when we woke up, and kept the fire going all day. When we were done making the tarp structure after dinner, we took the rocks (which were glowing by this point) out of the fire with a shovel, and put them in the hole in the tarp structure. I was very surprised at the amount of steam that came off when we poured the water on once we were inside. Word to the wise, don't continually hydrate yourself with beer (it's very easy to do), you will not feel well in the morning (you obviously sweat out a lot of water in the heat).

More to the point, you got me thinking about purchasing a cheap large tent, and a bucket like this. You would also need rocks that could be heated. But essentially the same as before; build a fire around the rocks, heat them for 1 hour + (the longer the better), set up the tent. After an hour or so, dig the rocks out of the fire, put them in the bucket, and then go in the tent, and splash water on the rocks. A portable tent and bucket could very easily fit in a van.
