Trade fairs shape industries. They bring together the people who design, build, and supply the spaces that define how we relax, recover, and connect. For PieksaWood, a Finnish family business with more than 75 years of experience in premium wood manufacturing, exhibiting at interbad 2026 in Stuttgart is a natural next step in our international journey. It is a chance to put our Finnish sauna wood in front of the professionals who are building the wellness spaces of tomorrow.
We have spent decades refining our craft in Pieksämäki, in the heart of the Savo region of Finland. We take our haapa, our Finnish aspen, through every stage of production, from the saw to the kiln to the planer. Now we are bringing the results of that work to one of the world’s most important platforms for the sauna, spa, and wellness industries. This article explains what drives that decision and what it means for the professionals who will be there alongside us.
What interbad 2026 means for the sauna industry
Held every four years in Stuttgart, Germany, interbad is the leading international trade fair for swimming, sauna, spa, and wellness. It brings together suppliers, architects, developers, and operators from across Europe and beyond to explore the latest products, technologies, and design directions shaping the global wellness sector. For anyone working in commercial sauna construction, spa development, or wellness architecture, this event is a professional benchmark.
The sauna industry has experienced a significant shift in recent years. Demand for authentic, high-quality sauna experiences has grown steadily across hotel and hospitality projects, residential wellness spaces, and public leisure facilities. Architects and developers are no longer treating the sauna as an afterthought. It has become a centrepiece of wellness design, and the materials used to build it are receiving the scrutiny they deserve. interbad 2026 reflects this evolution, offering a platform where material quality, sustainability, and design innovation sit at the centre of the conversation.
Why professionals attend interbad
For procurement professionals, contractors, and spa developers, interbad is an efficient way to evaluate suppliers, compare product quality in person, and build relationships that support long-term projects. Seeing and touching sauna wood in person matters. The grain, the density, the smoothness of a well-planed bench board, these are qualities that no product brochure can fully convey.
For manufacturers and suppliers like us, the fair represents a concentrated opportunity to connect with exactly the professionals who specify and purchase premium sauna materials at scale. Professionals interested in the full scope of what the exhibition covers can explore the programme on the official interbad website. The event genuinely functions as a crossroads for the international wellness industry, and its timing in 2026 coincides with a period of strong growth in sauna and spa construction across Europe.
How PieksaWood’s Finnish craftsmanship stands out internationally
Finnish wood craftsmanship carries a particular weight in the global sauna industry. Finland is, by any measure, the home of sauna culture, and the standards applied to sauna materials there reflect generations of practical knowledge about how wood performs under heat, steam, and constant use. We bring that knowledge to every product we make.
What sets us apart is not simply our location but our level of vertical integration. We operate our own aspen sawmill in Pieksämäki, process timber through our own modern thermal modification facility, and plane and inspect every finished product by hand before it leaves our production floor. This means we control quality at every stage of the supply chain, from raw log to finished sauna panel. For international buyers, that consistency is a significant advantage. When a hotel developer in central Europe specifies Finnish aspen bench boards for a spa project, they need to know that every delivery will meet the same standard. We can guarantee that because we never outsource the critical steps.
The role of thermal modification in premium sauna wood
Thermally modified wood has become an increasingly important category in sauna and wellness construction. The modification process, which uses heat and steam without any chemical additives, improves the wood’s dimensional stability, resistance to moisture, and long-term durability. For sauna environments where temperature and humidity fluctuate constantly, these properties are not a luxury but a practical requirement.
We have more than 20 years of experience in thermal modification, with a particular focus on aspen and black alder. Both species are well suited to the process, and the results produce a material that combines the natural warmth and texture of Nordic wood with enhanced performance characteristics. Our thermally modified aspen and sauna wood products, in particular, has become a trusted choice for commercial sauna projects where longevity and consistent appearance are essential. We also offer thermally modified radiata pine for clients who require an alternative species with similar performance benefits.
Products PieksaWood is bringing to interbad 2026
At interbad 2026, we will present the core of our sauna and wellness product range, with a focus on the materials that matter most to professional buyers working on commercial and high-end residential projects.
Our sauna bench boards in Finnish aspen and black alder will be central to our exhibition. Both species are knot-free and resin-free, which means they do not become uncomfortably hot to the touch even in high-temperature sauna conditions. The surface of well-planed aspen has a smooth, almost silky quality that is immediately noticeable, and it is a quality we maintain through careful production at every stage. These are not commodity products. They are the result of deliberate material selection, precise sawing, and skilled finishing.
Sauna panels and interior cladding
Alongside bench materials, we will showcase our range of sauna panels for walls and ceilings. Finnish aspen and black alder cladding creates a consistent, refined interior aesthetic that suits both traditional sauna design and more contemporary wellness architecture. The natural pale tones of aspen and the warmer, richer colour of black alder give designers and architects a choice of visual directions without compromising on performance.
Our thermally modified range will also be on display, giving visitors the opportunity to compare modified and unmodified versions of the same species side by side. For spa developers and hotel project managers evaluating materials for high-use environments, this direct comparison is genuinely useful.
Custom solutions for professional projects
One aspect of our offer that we are particularly keen to discuss at interbad is our capacity for custom dimensions and tailored specifications. We understand that commercial sauna projects rarely fit a standard template. Architects and contractors often need specific board widths, lengths, or surface profiles that standard catalogue products do not cover. We work flexibly with our clients to accommodate these requirements, and our production setup in Pieksämäki allows us to respond to custom requests without the long lead times that larger, less agile manufacturers often impose.
Who PieksaWood wants to meet at the fair
interbad 2026 attracts a broad professional audience, and we are genuinely interested in conversations with several distinct groups. Each brings a different perspective on how premium sauna wood fits into their work, and each represents a different kind of long-term partnership.
Sauna manufacturers and prefabricated sauna brands are among the most important visitors for us. These companies need a reliable, consistent supply of high-quality bench wood and cladding, and they benefit directly from our ability to maintain tight tolerances and deliver to schedule. For a manufacturer producing sauna cabins at volume, material consistency is not a preference but a production requirement.
Architects, designers, and spa developers
Architects and interior designers working on hotel spa projects, wellness centres, and luxury residential developments are another key audience. These professionals are often looking for materials that offer both aesthetic distinction and verified performance. Finnish aspen and black alder carry a natural story, a genuine connection to Nordic sauna culture, that adds meaning to a wellness space beyond its physical appearance. We welcome conversations with designers who want to explore how our wood can serve their vision.
Spa developers and hotel operators are increasingly specifying sauna materials at an earlier stage of the design process, which means the conversation about wood quality is happening at the planning table rather than on the construction site. We are well placed to support that process, offering material samples, technical specifications, and direct dialogue with our production team in Finland.
Distributors and building material importers
We are also actively looking to expand our network of distribution partners across Europe. Hardware retailers, specialist wood suppliers, and building material importers who serve the construction and wellness sectors represent an important channel for reaching professional buyers who may not attend trade fairs directly. If you are evaluating Finnish wood products for your catalogue, interbad 2026 is an excellent opportunity to see our range in person and discuss partnership terms.
