This project began somewhere in March. Okay, maybe that is not entirely true: it actually began when I was sixteen years old, when my big brother -the most inventive engineer I know- crafted a wood burning stove with a water heating system to warm up our inflatable kiddy pool. Due to the enormous succes of the invention, he and my dad quickly replaced the inflatable pool by a more durable tub made from something that was previously used as a cattle watering tub, and hence the first DIY hot tub of our family was born.
When I first took Joost to my parents' house, and showed him the hottub made by my big bro and my dad, he immediately responded: "We should totally make something like that!
