Say hello to the UNION Sauna (3–5 person) — the latest addition to our collection. With its sleek rounded-square design and sustainably sourced thermo-treated Nordic Spruce, it beautifully balances modern style with timeless tradition. Perfect by the pool or set within your garden, the UNION brings the authentic Finnish sauna experience into your home. With Shym Saunas, relaxation and meaningful moments come together where classic craftsmanship meets contemporary elegance.
Enjoy the effortless assembly of the UNION Sauna, thoughtfully designed with preassembled components for a quick, seamless setup. Using precision-cut log technology, it delivers both sturdiness and spacious comfort. Crafted from premium thermo-treated Nordic Spruce, the UNION reflects true luxury, sustainability, and efficient thermal control — a peaceful retreat right in your home.
Inspired by our much-loved square barrel saunas, the UNION was created as a European-made equivalent, crafted to the highest standards with thermo-treated spruce. Available in compact 1.25m, 1.6m, and 2.2m versions, it introduces a unique bench layout and refined details such as black pre-painted plywood skirting boards — combining practicality with an added touch of sophistication.
The UNION Sauna is built from 42mm thick thermo-treated spruce — a sustainable, eco-friendly timber chosen for its purity and strength. Through an exacting heat treatment process, all resins and chemicals are removed, leaving the wood completely non-toxic. This not only enhances the health benefits of every sauna session but also reflects our dedication to environmentally conscious craftsmanship.
The treatment further stabilises the timber, protecting it against warping or splitting over time. By choosing thermowood, you embrace both durability and responsibility — a sustainable choice that lessens environmental impact. With the UNION, luxury and wellness come together in a sauna that embodies care for both people and the planet.
Our UNION Saunas are delivered in a convenient kit, thoughtfully designed to make assembly simple. Using a trusted barrel-style method, each wallboard stacks securely onto the next, with components carefully crafted and tested in our Estonian factory to ensure lasting quality.
From the moment your sauna arrives, setup is quick and effortless — so you can move seamlessly from delivery to your very first session of relaxation. The ease of assembly ensures a stress-free, enjoyable start to your sauna experience.
Designed for simplicity and efficiency, our UNION saunas employ barrel assembly technology. The precisely cut staves effortlessly interlock, shaping a snug yet spacious environment. Step away from the outside world and discover tranquility in the warmth of our skillfully crafted sauna.
The UNION series sauna roof, while designed with a bold, boxy appearance, features a carefully crafted, subtle curvature. This rounded design maximizes water drainage, keeping your sauna dry and well-protected in any weather. This thoughtful detail combines style with functionality, ensuring that the UNION series delivers both aesthetic appeal and practical performance.
The UNION Sauna is built with 42mm thick stave boards, designed to maximise thermal efficiency by retaining heat with ease. This thoughtful construction allows the sauna to reach your desired temperature quickly and maintain it consistently, ensuring every session is warm, steady, and deeply rejuvenating.
A defining feature of the UNION series is its 8mm tinted glass panes. These not only elevate the sauna’s sleek, modern design but also offer enhanced privacy, creating a serene space to unwind. Say goodbye to temperature dips and step into the continuous, soothing warmth of your UNION Sauna.
Indulge in true cabin sauna comfort with the UNION Sauna’s thoughtfully designed split-level benches. Crafted from premium Thermo-Aspen, they create the perfect setting for relaxation, offering varied heat levels to suit every preference.
Settle onto the upper bench for an invigorating, high-heat session, or choose the lower bench for a gentler, calming warmth — each experience adapts to your comfort. The UNION series also features curved, ergonomic seating, adding an extra layer of support so you can fully unwind and rejuvenate.
At the heart of every UNION Sauna is sustainably harvested Nordic Spruce — sourced from responsibly managed forests to ensure a lasting, positive impact on the environment.
Renowned for its strength and beauty, Nordic Spruce enhances each sauna with a natural elegance, creating a warm and inviting atmosphere that reflects the true Finnish sauna tradition. By choosing this timber, we not only ensure the longevity of your sauna but also honour a commitment to preserving forests for generations to come.
Designed with your comfort at heart, the UNION Sauna features premium knotless Thermo-Treated Aspen benches. Lightweight yet durable, this carefully selected timber provides a smooth, seamless surface that feels as luxurious as it looks.
Every detail is crafted to enhance relaxation — from the gentle touch of the Aspen to the inviting warmth it creates. To elevate the experience further, the UNION series includes curved ergonomic benches, offering superior support and comfort as you unwind, rejuvenate, and enjoy every moment.
The expansive windows, now upgraded to 8 mm double glazed mirror or bronze, not only flood the interior with warmth and light but also transform the sauna’s exterior.
Experience a captivating play of reflections that enhances the perception of space around your sauna, creating a stunning visual impact. The mirrored windows offer a unique blend of aesthetics and functionality, allowing ample light to filter through while ensuring the utmost privacy for those indulging in the sauna experience. Revel in the seamless harmony of style and discretion as you bask in the soothing ambiance of our innovatively designed sauna.

Lina Yeo-Blake –
I’ve been corresponding with Art over the last couple of years for our sauna (delay in house build) and he has been super accommodating throughout, including personally installing our sauna too. Without a doubt I recommend Shym Sauna if you are thinking about getting an authentic sauna or hot tub. We love ours and super appreciate Art for his detailed instructions and guidance in making sure we make full use of sauna.
Boris Goloub –
It is a pleasure to have business with the seller. They stay in touch and are helpful through the way, prepared to resolve whatever a need might appear. The sauna itself is the quality and enjoyment.
