I was looking through some of the 1-2 person Infrared Saunas on Amazon.
They are expensive. I have tried the infrared sauna and prefer the Traditional hot rocks with water. I like the Steam. There are some DIY kits where you frame up your own 6’ x 5’ sauna that will cost you about $3,000 for the cedar interior and Electric Stove. (see below)
This is the little Steam unit for $96

I found this little personal Steem Sauna on Amazon for $165 and might give it a try ....
Maybe with a cedar bench and cedar floor it could be pretty nice ?

Looking at the very low Covid Numbers in Finland I wonder if a sauna might provide some resistance if we get a second wave in the fall.
