A perennial cottage sauna favourite with a water tank


Harvia 20 LS Pro and 20 RS Pro with water container on the side are practical stoves that provide a good, hot sauna bath. Water will be heated in the 30-litre water container by the time your sauna is ready for bathing.  Through the cast-iron glass door the warm glow of the fire adds to the sauna atmosphere. The sturdy 10 mm fire space cover ensures durability. The stove features a big stone space and an air-flow spoiler made of stainless steel. The stove is also equipped with adjustable legs.

Harvia 20 LS Pro has the water container on the left side, while 20 RS Pro has it on the right side. Together with Harvia 20 ES Pro, it is now easy to choose the water heater equipped stove that fits your sauna best.

The fire chamber and combustion air channels of Harvia stoves are designed so that sauna warms quickly and the burning is cleaner. The stoves meet the requirements for CE-marking.

The recommended size of the sauna room is 8–20 m3 and the maximum amount of stones is 40 kg.
