    Why choose SaunEco?

    1. We carefully evaluate each and every product we sell

    Our wooden hot tubs are built to last. We use only the highest quality dried wood (spruce, larch or thermo) and or tubs are made by professional, knowledgeable and experienced craftsmen.

    We only use slow grown wood. In the cold climate of Scandinavia trees grow slowly and therefore become durable and hardy. This ensures that the water is absorbed by the wood, that the wood swells and the wooden hot tub remains 100% water-tight.

    All our wood burning hot tubs and barrel saunas are treated with natural wood oil.

    The heaters that we use in our wooden hot tubs are made of high quality marine aluminum. The advantage of the aluminum furnace is that it has better thermal conductivity, which saves you both time and heating material. Aluminum heaters are also 30% lighter.

    High-quality MIG welding ensures the perfect end result. We check and test impermeability of all welded seams.

    2. We provide a 3-year warranty

    We provide a 3-year warranty on all our saunas and hot tubs. We are stable and secure and you can be confident that we’ll be here when you need us. Our products are manufactured under the highest quality standards. Starting from incoming control up to the final inspection stage.

    Hot tub benefits

    Who wouldn’t love to relax in a large bathtub that has room for 4 or more people?
    Why not do it in the garden at the time and in the company of your choosing?

    Buy the wooden hot tub and enjoy unique moments in the open air and in a company with your closest people in any weather and all year round. The wooden barrel sauna is designed to be used by people of any age and at any time.

    Many of us can’t hear birdsongs or see the stars in the sky while taking a bath in the bathtub, but comfortable bathing barrels make it a reality.

    Therapeutic effect

    Bathing in hot water is widespread all over the world. Natural hot water springs can be found in many parts of our planet in seismically active regions – in Iceland, Japan, New Zealand, as well as in Central European countries – Hungary and Slovakia. But not everybody has an opportunity to bathe in natural hot water springs, let alone having an own hot water spring. That’s why the wooden hot tub was invented.

    In order to increase the pleasure one can add a couple of drops of ethereal oils to the bathing water (grapefruit, juniper or fennel, which improve metabolism and lymph circulation). Herbal medicine is good for your body, mind and feelings.

    After hot tub you will feel reborn, the spirit will feel fresh and the body rested.

    Made of natural wood

    Birch Whisks from SaunecoThe most environmentally friendly and economical building material.

    Wood is the only truly renewable natural resource that has a number of functional properties – a naturally warm and beautiful appearance and good price, which can’t be achieved with use of artificial alternatives.

    Proper impregnation of wood using modern wood treatment means and technologies increases durability and properties of wood, as well as demand for it.

    Production is economical

    Sustainable production and consumption mean that provision of services and products, as well as their consumption, don’t harm the natural environment and society. This is the key to sustainable way of life.

    This means the choice of a lifestyle that protects and preserves natural resources and helps to maintain people’s good health and well-being all over the world.

    Some might feel that is sounds a bit idealistic, but we should stick to this idea if we want to turn the world to the right rut. It is a mistake to think that sustainability only requires reducing consumption. Instead, it rather means more efficient consumption and, at the same time, better quality of life.

    So that first and foremost we could satisfy our primary needs and at the same time feel confident that the products we use contain no toxic agents and that natural resources are not wasted during production.

    Wood is environmentally friendly

    TSauneco Saunas and Hot Tubshe use of wood as material and fuel was one of the earliest ways to use plants. Wood is a renewable raw material that offers very diverse ways of use and it still belongs to one of the most important groups of products obtained from plants.

    Environmentally friendly (sustainable) consumption means high level of awareness of people (citizens, private and public sectors) that make conscious choices in favor of the products that have as little environmental impact as possible, since they offer environmentally-friendly technologies, longer useful life, rehashing, better options for repeated use and upgrading, or options to be used by several people.


    The hot tub can be easily relocated on an even and durable surface.

    You don´t need for a building permit when you buy our hot tub, and its location on your land or in the garden can be chosen by you personally. Also you don´t need for a foundation or any other bulky preparations.


    Thermally Modified Wood

    Thermo-processed wood is produced by treating softwood timber in kilns at very high temperatures which alters the cellular structures of the timber. As a result that makes the timber far more stable, especially so in changing climates.

    What is kilning?

    The process of kilning the timber is environmentally friendly. Thermo-processed wood is made through a chemical-free process using heat vapour and steam. The wood material is heated to a temperature of at least 180 degrees Celsius while it is protected with steam.


    Sauna Bench Protection From Sauneco1. As a result of the thermo process the form stability of normal softwoods such as pine and spruce can be significantly improved.

    2. Thermal processing completely eliminates resin.

    3. Thermal processing increases durability of wood and increases immunity against impact of environment. For example, thermally processed wood according to its durability characteristics can be compared to oak.

    4. Thermo-processed wood is darker than natural wood, more weatherproof and more resistant to rot.

    5. Its insulation qualities are better, it suffers from less moisture deformation and is more stable.

    6. The equilibrium moisture is up to 50% less than natural wood, which makes thermo-processed wood a better option for use in outdoor conditions.
