Picture of HillBilly Hot Tub
Here in the UK it's been a great summer and I thought it would be good to relax at the end of the day in a nice hot tub. Trouble is they are quite expensive to buy and run and you need power and chemicals and really how many times would you use one. So I decided to build a low cost hot tub which can be run off grid and can be used quick and cheaply to have some fun.

I mean i know that my money value is 2• what yours is but it would make it easyer

Nice but, could you convert in ( ) american money value?
Try a homemade it reflector above the tub. line the underside of a garden parasol etc with reflective aluminized snack packets, Dorreetos are among the best. They are much more durable than space blankets. It DOESN'T need to be in contact. I promise you will be amazed. john

Great Idea, now for a 'mod'! If you were to cut out most of the bottom of the bin, leaving say a 1" rim inside, you could put a stout mesh inside. Put the bin on a coupla bricks. Then as your fire fuel burnt to ash, the ash'd fall out the bottom making yr unit self cleaning!

great idea! Now a little 'mod' for you! If you cut the bottom out of the bin and put some stout mesh in there, you can stand yr bin on a coupla bricks and as the fire burns, the ash'll fall out the bottom...making it self cleaning!

In the UK we sometimes like the off grid Hillbilly lifestyle :-) - but the heating coil is the same design as a Hillbilly Moonshine still.

You could use this on any pond or paddling pool, maybe even stoke a small fire to stop a fish-pond freezing in winter.
richiemcb (author)  Kiteman2 years ago
Yes - good idea for fish ponds - just need some wood and a battery to get going.

Seems like it could get a bit too hot and the rubber could come apart, but pretty dang fun looking man!
