An oval barrel sauna is an outdoor oval shaped sauna with two benches and sauna heater. With this unique form the oval barrel-shaped sauna fits perfectly in any garden. Oval barrel-shaped saunas have better heat circulation than box-shaped ones. Compared with the box-shaped saunas, oval barrel-shaped saunas have up to 25% reduced heating zone. Therefore an oval barrel-shaped sauna is ready to use much faster and you need less electricity or firewood.

FOREST SPA produces saunas from Siberian spruce, Siberian larch and Thermowood. This type of wood is very durable, weather resistant and also gives a pleasant aroma. Our saunas are treated with linseed oil or paint to seal and protect the wood from moisture and dirt. Follow the latest trend and choose a barrel sauna that will seamlessly integrate into your garden.

WHAT TYPE OF WOOD TO CHOOSE FOR A SAUNA? Click here for more information.

Saunas from FOREST SPA can be made from 3 wood types:

  • Siberian Spruce;
  • Siberian Larch;
  • Thermowood.

The timber used forour saunas is imported from Siberia or Finland; the wood grows slowly in the cold climate and is much thicker and more resilient than timber grown in the warmer areas of Europe.

Spruce is white coloured, light, soft, flexible and naturally good looking. It is one of the strongest types of timber and is imported from Siberia. Spruce is the cheapest option but it is susceptible to rot therefore must be regularly treated and sealed. In order to make a sauna more durable it is necessary to impregnate the outside surface of the sauna at least once a year. If you do so you will be able to use a spruce sauna for 15-20 years.

Larch is light red or brown coloured, strong, hard, water-proof and above all – rot resistant. It doesn’t conduct heat and doesn’t leak resin. Because of its density it is very durable even without additional finishing and requires no harmful chemicals to preserve it. It is virtually irreplaceable in situations where chemical finishing of wood is not permitted but its durability in all weather conditions must be guaranteed. Over time its resilience and density will only grow so you will be able to use a larch sauna for 25-30 years. The only downside is that larch swells and shrinks more than spruce therefore some gaps may occur between the planks over time. Saunas made from Siberian larch give the optimum price/quality combination.

Termowood (Wikipedia) is darker than natural wood, more weather-proof and more resistant to rot. Its insulation qualities are better, it suffers from less moisture deformation and is more stable. The manufacturing process of Thermowood is based on the use of high temperature and steam. No chemicals are used in its production.  The production process improves the dimensional stability and biological durability of the wood. Another improvement is in the insulation properties of the final material.  Thermally treated wood swells and shrinks about a quarter less than untreated wood. Therefore Termowood is excellent for exterior saunas, you will be able to use a Termowood sauna for 25-30 years.
