EOS Cubius Stones (S35) offer a distinctive way to transform the look and feel of your EOS Mythos S35 sauna heater while enhancing overall heat performance. Crafted from solid soapstone, each cubic piece absorbs and stores thermal energy efficiently, then releases it gradually to support longer, more aromatic infusion sessions. The uniform geometric shape stacks neatly within the included stainless steel mounting frame, creating a clean, architectural appearance that elevates the heater from a functional unit to a design feature. Available in natural soapstone or in coated black and white editions with heat- and scratch-resistant surfaces, the set of twenty stones allows you to tailor the visual tone of your sauna. With their balance of durability, thermal stability, and modern styling, EOS Cubius Stones (S35) provide a refined upgrade that complements both contemporary and classic sauna interiors.

  • Solid soapstone thermal core – Each cubic stone is carved from dense soapstone that absorbs and stores heat efficiently, then releases it slowly, supporting more stable temperatures and longer, more aromatic infusion sessions with every sauna cycle.
  • Modern cubic design – Uniform geometric shapes create a clean, architectural stone column inside the heater, turning the EOS Mythos S35 into a design feature that visually elevates both contemporary and classic sauna interiors.
  • Longer-lasting infusions – High thermal mass helps the stones retain heat between ladles of water, extending the duration and consistency of steam and fragrance so each infusion feels richer and more immersive.
  • Three coordinated finishes – Available in natural, black, and white options, the stones let you match or contrast surrounding wood tones and heater trim, giving you precise control over the visual tone of your sauna.
  • Durable color coating – Black and white editions feature a heat- and scratch-resistant coating that resists fading and discoloration, preserving a crisp, premium appearance even under frequent high-temperature use and regular cleaning.
  • Integrated mounting frame – Supplied with a stainless steel mounting frame and twenty stones, the set is engineered specifically for EOS Mythos S35 heaters, simplifying installation and ensuring a secure, properly supported stone arrangement.
  • MPN: Black 945942 / White 945938 / Natural 945520
  • Compatibility: EOS Mythos S35 sauna heater
