400 S
The Yakia 400 S is a compact yet beautifully crafted outdoor sauna, designed to bring authentic sauna wellness into smaller outdoor spaces. Ideal for two people, it combines clean design, natural materials and reliable performance to create a calm and restorative retreat at home.
Built from premium Thermowood, the 400 S features a 6kW electric wall-mounted heater, atmospheric LED lighting to the benches and backrest, and elegant two-level Thermo-Aspen benches for comfort and relaxation. Bronze tempered glazing to the door and window adds a refined contemporary finish, making the 400 S a stylish addition to any garden.
Exterior Wood Treatment – Important
Yakia saunas are crafted from premium Thermowood, a heat-treated timber chosen for its durability and resistance to rot, insects and moisture. As a natural material, the exterior timber will gradually weather over time if left untreated.
To preserve its appearance and support long-term performance, all external timber must be treated with a high-quality wood preservative immediately after installation.
Please note that failure to carry out this treatment will invalidate the warranty. Yakia recommends Ronseal Trade Total Wood Preserver (Clear) for optimum protection.

The Benefits of Sauna Wellness
Relax. Recover. Reconnect.
A Yakia sauna is more than a source of heat — it is a space to slow down, reset and focus on your wellbeing. For generations, saunas have been valued for their ability to support both physical and mental wellness, offering a simple and natural way to relax, recover and restore balance.
The gentle, enveloping heat helps to ease stress and tension, creating a deep sense of relaxation while encouraging mental clarity. Regular sauna use can also stimulate circulation, helping to support cardiovascular health, reduce muscle soreness and aid recovery after exercise or a busy day.
As the body warms, natural sweating helps cleanse the skin and support the body’s natural detoxification process, while the improved blood flow can leave skin looking fresher and more radiant. Many people also find that regular sauna sessions help them unwind in the evening, making it easier to enjoy deeper, more restful sleep.
From post-workout recovery to everyday relaxation, a Yakia sauna offers a timeless wellness experience designed to support body and mind in the comfort of your own home.
