How hard is it to assemble one of those barrel sauna kits?
I was wondering the same thing not long ago, so I looked up some videos reviewing those kits. It turns out that how hard it is to build one of those greatly depends on which kit you choose to buy. There is a lot of variation in how much work manufacturers expect buyers to do.
Some kits only require that you know how to use a hammer and a screwdriver. While others will require power tools to properly assemble. It depends on the kit. Depending on how large the barrel sauna is, building it may require the help of several people too.
If you’re planning on buying one of those barrel sauna kits, the best thing to do is to check the assembly instructions before you buy. Plenty of stores will have PDFs of the instructions available online — this website is a good example. You can check the instructions and determine from there whether or not a given kit is too complicated to be worth the bother.
