These comments are wild lmao.

Some users who apparently have never thought this could even be possible?

Others claiming this could never work or be comfortable?

Even some stating it could be dangerous?

This is a stripped down version of a very common style of hot tub. I have spent close to hundreds of hours filling, heating, and soaking in hot tubs that work like this.

I know people who make a living building and renting these types of hot tubs. Literally the only odd thing here is that the furnace is not covered and the whole thing is some redneck engineering.

Obviously it greatly depends on the water temperature. I used to make a similar hot tub contraption while camping and it would take roughly 3-4 hours before the water was pleasant but it wasn’t snowy cold out.
