Product information updated 2026-11-11
There is no metal casing inside – seawater can be used. This creates a healing marine climate. The inner casing is made of „Celsius“ – an extremely strong, heat-resistant ceramic compound, and the outer one – of talcomagnesite with the new „Grafia“ surface treatment. To heat up „Grinion“, 50 kg of firewood and 4–5 hours are enough. The efficiency reaches 75 %, which is an exceptional figure for sauna heaters. The standard package includes an internal 135kg stone fill (16-35 m3). An additional 60 kg of stones are required for the top layer (25-45m3).
