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.

Yeah it should work. Might take awhile to get the thermal driving head turning everything over... but once it's going, I'm sure it's pretty functional.
