The EOS Cubius S35 is the 20-piece soapstone cube set with a stainless mounting frame, made for the EOS Mythos S35 heater. The cubes sit in the heater’s upper stone area and give the Mythos its cube look. They do not replace the heater’s regular sauna stones. Cubius stones are optional on standard-finish Mythos heaters; some Mythos black and white versions ship with matching Cubius stones from the factory.
What’s included
EOS Cubius S35 Stones with Mounting Frame, 20 pcs as selected
Heater not included
Specs
Brand: EOS Saunatechnik (Germany)
Type: Designer soapstone cubes with stainless mounting frame
Does Mythos already include Cubius? Not on standard-finish Mythos heaters, where Cubius is optional. Some Mythos black and white versions ship with matching Cubius stones from the factory, so this set is for a standard-finish heater, a spare, or a color change.
