It’s one of the idyls of our age, to imagine oneself lounging in a hot tub watching a golden sunset, glass of wine in hand and the love of your life at your side. Along the way though it’s one that’s become diverted from the original, instead of a Scandinavian style wood fired tub in the forest we’re more likely to be thinking of an electric whirlpool spa made from fibreglass, as much a status symbol as a leisure item. It’s refreshing then to see [sirClogg]’s home made hot tub, a simple wooden tub with associated wood stove to heat its water. We can’t wait to step in!
The tub is simplicity itself, being made from softwood planks held together under tension by some steel cables. He admits though that he made a mistake using green wood, as it has now contracted leaving the tub with some gaps. But it’s a simple enough build that he can contemplate dismantling and rebuilding it to correct for that oversight.
Heat meanwhile is provided by a pipe that circulates water from the bottom of the tub through a heat exchanger coil inside a brick-built wood stove adjacent to the tub. The fabrication of the heat exchanger is detailed in the video below, we enjoyed seeing the copper piping filled with salt to ensure it doesn’t collapse when being bent around a five-gallon bucket. It doesn’t get much simpler than this, and the reward of a hot tub must be a sweet one indeed.
