EOS Cubo Avantgarde 208/3 Freestanding Electric Sauna Heater, 208V/3PH, up to 12kW

The EOS Cubo Avantgarde is a premium electric sauna heater that delivers exceptional performance in a luxurious, ultra-modern design.

The matte black Cubo Avantgarde is constructed from durable powder-coated steel, which is scratch-resistant to protect its contemporary exterior. With its symetrical dimensions on all sides, the heater complements sauna rooms of any installation configuration. Its distinctive stylized upper stone basket is secured to the top of the heater and cradles decorative white quartz sauna stones for a dramatic visual impact. Layered above the internal diabase sauna stones, the added rocks improve heat retention and increase steam production when water is poured.

Featuring heating elements not directly contacting sauna stones and secure access to wiring connections, the Cubo Avantgarde is extremely efficient and service friendly. Boasting a large rock capacity relative to its compact footprint, the heater optimizes air convection for quick heat-up times, superior performance, and powerful sauna sessions.

Protected by a 2-year warranty, the Cubo Avantgarde offers an exceptional blend of precise craftsmanship and optimized performance to bring your sauna to life.
