DEIZ creates outdoor saunas as architectural wooden objects rather than conventional garden buildings. We combine CLT panels developed specifically for our saunas with clean geometry, panoramic glazing, factory-controlled production and flexible configuration. Each sauna is designed around natural timber, proportion, privacy and the way it becomes part of its surroundings.
A DEIZ sauna is developed as one complete system - from the CLT structure and visible timber surfaces to panoramic glazing, ventilation, roofing and interior details. Critical elements are prepared in controlled production conditions to maintain accurate geometry, consistent detailing and predictable assembly on site.
CLT (Cross-Laminated Timber) is a solid timber panel made from layers of wood arranged in alternating directions, creating a rigid and geometrically stable structure. DEIZ CLT panels are developed specifically for sauna construction and visible timber surfaces. Additional bonding between the lamellas, narrower lamellas of approximately 50 mm and carefully selected visible faces help create a cleaner, more continuous architectural surface.

CLT stands for Cross-Laminated Timber. It is a solid timber panel made from layers of wood arranged in alternating directions, creating a rigid and geometrically stable structure. In a DEIZ sauna, the CLT panel forms the main structure and can also remain visible as the finished timber surface, creating a clean and solid architectural interior.
DEIZ CLT panels are developed specifically for sauna construction and visible timber surfaces. In addition to bonding between the timber layers, the lamellas are also bonded along their edges. Narrower lamellas of approximately 50 mm and carefully selected visible faces help create a cleaner, more continuous wooden surface.
The main difference is the construction. A barrel sauna is formed from individual boards, while a typical frame sauna uses a structural frame with insulation and interior or exterior cladding. DEIZ uses solid CLT panels as the main structure, allowing the sauna to have a rectangular architectural form and a more continuous visible timber surface.
The standard DEIZ sauna is not insulated: walls and ceiling are solid 54 mm CLT panels with visible timber surfaces. Insulation is available as a paid option and is defined for the individual configuration.
Wood is a natural material and reacts to moisture, sunlight and temperature changes. Dark facade colours can heat considerably more in direct sunlight, which may lead to stronger drying, micro-cracks or visual changes, so light and medium shades are often the more stable choice.
Yes. DEIZ has standard models, but the project can be adapted in size, layout, glazing, doors, heater, facade colour and interior or exterior finish. Options can include a terrace, anteroom, shower area or other changes where they are technically suitable for the project.
DEIZ offers two delivery formats. The assembled sauna needs access for a truck, crane or manipulator. Where that is not possible, every model is available as a DIY Kit: panels prepared for manual assembly, usually by two people, without heavy machinery.
The final price depends on the model, size, layout, glazing, doors, heater, finish, additional options and delivery requirements. Site access can also affect the delivery and installation solution. Standard models provide a starting point, while customized projects are calculated according to the selected configuration.
A DEIZ sauna requires a level and stable base prepared before installation. For fully assembled delivery, access for the truck, crane or manipulator should be checked in advance, including gates, trees, overhead cables and ground conditions. Exact foundation and access requirements depend on the model and installation site.
Electric sauna heaters require a suitable three-phase electrical connection. The exact power requirement, cable specification, protection and connection method depend on the selected heater and must be confirmed for the individual project and local electrical requirements.
