Product Description

EOS Invisio Midi Freestanding Sauna Heater

The EOS Gracil W Sauna Heater brings the elegant styling and performance of the Gracil series into a wall-mounted configuration. With its slim profile and minimal wall clearance requirements, the Gracil W maximizes usable floor space while delivering the authentic heat and steam expected from a premium Finnish sauna heater.

Finished in anthracite pearl effect with a brushed stainless steel top, the Gracil W enhances modern sauna interiors with understated sophistication. An integrated debris collection tray helps maintain a cleaner sauna environment, while the generous stone capacity provides consistent heat and satisfying löyly.
