The EOS Cubius S35 are precision-cut cubic soapstone sauna stones designed specifically for the EOS Mythos S35 heater. Secured to the stainless-steel mounting frame above the standard stone bed, they complete the Mythos S35's geometric aesthetic while enhancing airflow for balanced heat distribution and consistent steam output.

Crafted from solid natural soapstone, colored variations feature a heat and scratch-resistant coating that maintains its finish through repeated temperature cycles. Minimal dust generation during use, with recommended replacement every 18–24 months. Designed, engineered, and sculpted in Germany.
