Sauna heaters

Sauna stove / stones heater

— a ready-made solution for a steam room: electric (with heating elements and a thermostat) or wood-burning (with a firebox and chimney), with the key feature being the stone lining — it retains heat and makes the climate milder than simple heaters without stones. When comparing an electric sauna heater and a wood-burning one, the former excels in precise temperature control, convenience for an apartment/house, and quick start-up, while the latter is often appreciated for its "live" heat, independence, and atmosphere, but requires space, proper smoke removal, and adherence to fire safety clearances.
