Effects and Results
Even with a door made out of two pieces of canvas, I eventually found that the sauna was still retaining enough moisture, and toxins from my body, that I needed to add a ventilation system. The air could get very "thick", and a few times I found it difficult to breathe!
After considering two or three options, I decided to use a 1 foot long piece of 2" diameter PVC. I cut a 2" diameter hole in the top of the sauna, and mounted a 2" PVC flange, over the hole. By employing a 2" PVC cap, I can close the vent for pre-heating, and then remove the cap before I enter the sauna for a session. This has proved to work very well to allow just the right amount of ventilation, as air is pulled in past the gaps in the "door", and then exits through the vent in the top, without any noticeable drop in temperature!
The flange is mounted in the top of the sauna.
The PVC pipe is slipped into the flange.
The cap is put on the pipe for pre-heating,
and then removed during the session.
