Anyone had sauna for their Airbnb?

[Joel Oh]

Hey guys! I am planning to add an outdoor sauna for this new property. I am thinking about a Costco wooden barrel sauna.

How was your experience with sauna? I know for sure people will love it but I am wondering if there is anything I should be aware of. 

I have properties with swimming pool and playground so I am well aware of the risk management side but a winter item like this is a new for me! (I guess people still can take a sauna during 90 degree weather but well haha)

Also should I cover the top with gazebo structure? Or is it going to trap too much moisture? I am not sure how these saunas are good with snow and rain. 

Thanks guys!
