Modern Finnish sauna

In Finnish, "tyyni" means tranquility. This is precisely the idea behind a collection of modern outdoor saunas that offer a complete wellness experience enclosed in a single, stylish structure. This is because the compact and simple building contains not only a sauna chamber with a furnace, but also a recreational space and a shower room. Tyyni saunas are made of 90 mm thick cross-laminated timber (CLT), which has exceptional durability and weather resistance. CLT wood is environmentally friendly, provides excellent thermal and acoustic insulation, and allows the use of large glazing without sacrificing structural stability. Coniferous wood was used to create the saunas - pleasant to the touch and able to withstand demanding conditions of use.

Scandinavian design and luxurious relaxation in your garden

One of the key elements that distinguish modern Tyyni saunas is their unique design. The collection was designed by architect Piotr Gniewek and implemented by the Finnish company Ehta Group Oy. The saunas combine modern design with the multi-generational heritage of Scandinavian craftsmen to create a timeless object. The minimalist space draws inspiration from tradition and proven patterns that have shaped art and architecture since antiquity. The simple, geometric body is equipped with extensive mirrored glazing that blends in perfectly with the surroundings. The effect is enhanced by the wooden facade, emphasizing the natural character of the structure. As a result, the sauna perfectly complements the garden, offering the perfect place for a moment of respite from the daily hustle and bustle. Combining it with a terrace will create a unique space for both evening meetings with friends and romantic moments for two.

What are the benefits of your own garden sauna?

Regular use of the sauna has a beneficial effect on health and well-being, promoting blood circulation, cleansing the skin of toxins and speeding up muscle recovery after exercise. The heat relaxes tense muscles, reduces stress levels and improves the quality of sleep, making a sauna session the perfect ritual of relaxation after a long day. An in-house sauna is also synonymous with luxury and prestige, increasing the value of the property and offering homebuyers and guests a unique relaxation experience. In addition, the modern technologies used in Tyyni saunas allow you to save energy and care for the environment, making the use of the sauna not only pleasant, but also ecological. The possibility of combining the sauna with a terrace or garden further emphasizes its unique character, allowing you to create a private wellness area in harmony with nature.
