The EOS Cubius Loop 4 is a hand-carved soapstone sauna stone designed as a design-forward alternative to standard sauna stones. The Cubius Loop 4 Stone takes up 4x the amount of space as regular sized Cubius stone, with the S35 having space for up to 4 pcs & the S45 having space for up to 6 pcs. 

The Cubius Loop 4 stone is a more premium offering than the regular Cubius stones, with its larger surface area and carved basin allowing prolonged water infusions for greater steam length and distribution. 

Dense natural soapstone absorbs heat efficiently and releases it gradually — producing consistent, gentle steam and extending the duration of any added fragrances during sauna sessions.

The geometric shape complements the EOS Mythos S35 and S45 heater aesthetic, transforming the stone bed into a visual element of the sauna interior. Available in Natural, Black, and White finishes to match your heater and interior wood tones. Designed, engineered, and sculpted in Germany.
