Meet the UNION Sauna (3–6 person) — the latest highlight in our collection. Crafted from sustainably sourced, thermo-treated Nordic Spruce, its rounded-square design combines timeless tradition with modern style. Whether set beside the pool or nestled in the garden, the UNION offers an authentic Finnish sauna experience at home. With Shym Saunas, you can enjoy true relaxation and meaningful moments, where classic craftsmanship meets contemporary elegance.
Experience the simplicity of the UNION Sauna, designed with preassembled components for quick installation and a seamless setup. Built using precision-cut log technology, it offers both strength and generous comfort. Made from premium thermo-treated Nordic Spruce, the UNION combines sustainability, thermal efficiency, and timeless luxury — creating a tranquil retreat right at home.
Inspired by our much-loved square barrel saunas, the UNION was developed as a European-made equivalent crafted to the highest standards. Available in 1.25m, 1.6m, and 2.2m models, it offers flexible sizing, a unique bench layout, and elegant details such as black pre-painted plywood skirting boards for a refined touch of sophistication.
Each UNION Sauna is constructed from 42mm thick thermo-treated spruce — a sustainable, eco-friendly material that undergoes a precise heat treatment to remove all resins and chemicals. The result is completely non-toxic timber, enhancing both the health benefits and purity of your sauna experience.
This treatment also stabilises the wood, preventing warping or splitting over time. Choosing thermowood means choosing durability, responsibility, and reduced environmental impact. With the UNION Sauna, you can enjoy a luxurious escape that embodies both sustainability and the true spirit of sauna culture.
Our UNION Saunas arrive in a thoughtfully designed kit, making the assembly process simple and seamless. Using a trusted barrel-style method, each wallboard stacks securely onto the next, while precision-crafted components — produced and tested in our Estonian factory — ensure lasting quality.
From delivery to your very first sauna session, the setup is quick and effortless. This ease of assembly means you can move straight into enjoying the warmth, relaxation, and timeless comfort of your new sauna without delay.
Built for ease and efficiency, the UNION Sauna uses classic barrel assembly technology. Each precision-cut stave interlocks seamlessly, creating a secure structure that feels both spacious and inviting. It’s a space designed to let you step away from daily demands and immerse yourself in pure tranquility.
The UNION roof, with its bold, modern form, is subtly curved to enhance function. This gentle arch allows water to drain efficiently, keeping your sauna dry and protected in every season. Blending contemporary design with practical performance, the UNION offers a balance of style, durability, and comfort.
The UNION Sauna is expertly crafted with 42mm thick stave boards that optimize thermal efficiency by effectively retaining heat. This innovative design allows the sauna to quickly reach your desired temperature and maintain it throughout your session, guaranteeing a consistently warm and rejuvenating experience.
One of the standout features of the UNION series is the tinted 8mm glass panes, which not only enhance the sauna’s modern aesthetic but also provide added privacy. Bid farewell to temperature fluctuations and immerse yourself in the steady, soothing warmth of your UNION sauna for every session.
Experience true cabin sauna luxury with the UNION Sauna’s split-level bench design. Crafted from premium Thermo-Aspen, the benches create the ideal setting for relaxation, offering different heat levels to match your personal preference.
Settle onto the upper bench for an invigorating, high-heat session, or choose the lower bench for a gentler, calming warmth — every moment is designed around your comfort. The UNION series also features curved, ergonomic seating, bringing an added layer of support and ease as you unwind, restore, and embrace the sauna experience.
At the core of every UNION Sauna is sustainably harvested Nordic Spruce — a timber chosen not only for its strength and beauty but also for its harmony with the environment. Responsibly sourced from well-managed forests, it reflects our dedication to craftsmanship that respects nature.
The natural elegance of Nordic Spruce enhances the sauna’s design, creating a warm and welcoming atmosphere that stays true to the authentic Finnish tradition. By choosing this material, we ensure lasting durability while honouring a commitment to protect our forests for future generations.
Crafted with your ultimate comfort in focus, our sauna showcases premium knotless Thermo Treated Aspen benches. Chosen for their exceptional lightweight quality, these benches are designed not only to provide a next-level comfort experience but also to be a delight to the touch.
Embrace the luxurious feel of the benches, offering a seamless and smooth surface that enhances your overall relaxation. While prioritising comfort, these lightweight Aspen benches are tailored for a cozy, inviting experience, ensuring that every moment in your sauna is as delightful as it is tranquil.
Plus, the UNION series is uniquely equipped with curved ergonomic benches, ensuring a more comfortable seating experience as you unwind and rejuvenate.

kris crnomarkovic –
Artem of Shym Saunas was very helpful every step of the way. Construction of the sauna was easy, mostly by myself, just needing a bit of help when lifting and positioning the end pieces. Quality was good, and prices the most competitive by far.
Strongly recommended.
Tim Stewart –
Fantastic high quality product. With a good quality assembler and electrician the end product is awesome.
Colin –
Really pleased with the spa we bought. Have used it pretty much every weekend. Art was really helpful and the YouTube assembly guides were great and didn’t take long for the wood to swell and leaks to stop. Already scoping out a pad for a sauna. Next years project.
