This summer I built a much anticipated sauna structure on my property. I had some timbers that needed to get used, so it became my first timber framing project as well. The result is a very large sauna that consumed all of the time and money I had for the project for the time being. The floor is insulated, but it's unlikely that I'll be able to dive into additional insulating and finish carpentry until next summer.
So I have been trying to figure what will get my space, which is just under 1000 cubic feet, up near 200* for a couple hours.
I came across the cottage rocket while combing old permies threads and wondered if the non mass version might do the job. So, I'm putting these questions out there in hopes that someone may want to help me limp in the right direction:
Can a two barrel cottage rocket like the one attached get my space up to the desired temp?
Can I put a cottage rocket safely on a wooden floor?
Do plans exist for this stove and is anyone selling them? If not, it seems like there may be enough pictures in old threads to put together a pretty good approximation but I may need some guidance on a few more precise measurements.
Am I heading in the right direction? - I know this is a dangerous thing to post on a forum - but any input is welcome :)
I also want to thank all of you for posting your obscure problems and solutions on this and other forums. My partner and I are starting a homestead in upstate New York without any experience to speak of and it's all of your invaluable knowledge that makes it possible. Thank You!
So the person you really need to talk with is Chris McClellan aka Uncle Mud who is the designer of the cottage rocket.
Perhaps he will see the bat signal and respond with all the answers you seek. In the meantime, I can give you my take on some of your inquiries.
So 1000 cubic feet is 10x10x10 feet. I would say this heater would be able to handle that size no problem.
As you can see in the photo, the rocket is elevated off the ground with bricks leaving plenty of air space to help vent heat from transferring to the floor. Being that your only going to have the stove running a few hours, this would probably be enough but certainly wouldn't hurt to have extra and also to monitor with a thermometer to ensure safety.
I know Chris has done many workshops teaching people how to build them and I think may even have more info on them if you check out his patron page at: Patreon.com/unclemud

Look forward to hearing of your upcoming adventures and please take lots of photos.
Hi Jason, welcome to Permies! Luckily of all the forums you could've posted to, this one is likely the best.
I have zero input for your design, but I did want to mention that the subject of your project aligns perfectly with a portion of a badge in the Rocket part of the PEP program. So as you do your project you could post a few pictures to that thread and become certified for building a sauna. Nifty! Plus it's free.
