EOS Cubius Stones bring a bold and refined design to your sauna heater setup. Their unique cubic shape and solid soapstone construction improve both heat performance and style. These stones don’t just look good—they help your heater run better and make your infusions last longer.

Now offered in black, white, and natural finishes, you can create your own look with color combos or varying stone heights. The color editions feature a scratch- and heat-resistant coating that stays looking fresh. Each set includes 24 stones and a stainless steel mounting frame, made to fit perfectly in EOS Mythos 45 heaters.
