A Hot Tub Built for Two The Salty Duo is our compact, lightweight hot tub made for couples, mates, or solo soaking.It’s everything you love about the Salty Barrel — just smaller, l ighter, and even easier to take off-grid.Add water, light a fire, soak anywhere. Ultra Portable At just 21kg packed, the Duo is the world’s most portable hot tub.It’s designed for remote camps, tiny homes, van life, and minimalist missions where space matters. No Power? No Problem. All you need is water and fire. As the fire heats the water in the coil, it naturally rises and flows back into the tub. Cold water is pulled into the bottom of the coil to be heated — no pump, no wires.This process is called thermosyphon — and it works like magic. Small but Tough Just like the full-size Salty Barrel, the Duo is made to be used, abused, and thrown in the back of your truck.The stainless steel coil and fire-resistant tarpaulin tub are built to handle wild terrain and marine environments. More Than a Hot Tub Relax off-grid while your dinner cooks over the fire.The heating coil doubles as a BBQ — perfect for a wok or grill.Soak, cook, and enjoy the simple things.
