FAQS
Why a garden sauna from DERHOLZER?
Because a true garden sauna must defy the elements every single day. Storms, rain, hail, snow, and scorching heat—there is no room for compromise here.
That is exactly why we at DERHOLZER build with passion and an uncompromising commitment to quality. Our garden saunas feature exclusively ventilated cold roofs, massive wall thicknesses of 16 to 20 cm for perfect stability and outstanding thermal insulation, and a solid CLT floor slab as a stable foundation, complete with a waterproof sub-layer and high-quality tiled flooring. Every DERHOLZER garden sauna is intentionally built to last for generations.
We offer premium standard models perfectly tailored to most gardens and requirements. However, if none of these fit your exact needs, we will naturally plan and realize your garden sauna completely customized to your vision. With DERHOLZER, you don’t just get a standard product—you get your personal paradise for life.
Physically Correct Construction – No Compromises Every DERHOLZER garden sauna is engineered according to the highest building physics standards—ensuring quality that lasts for generations and represents a future-proof investment in your personal wellness paradise.
Ventilated Cold Roof Our ventilated cold roof ensures permanent air circulation and prevents moisture buildup—keeping your garden sauna permanently dry and mold-free, even through storms, rain, hail, and extreme heat.
Multi-Layer Wall Ventilation Several intelligent ventilation layers allow the walls to “breathe” perfectly, providing long-term protection against condensation, mold, and premature aging.
Massive 16–20 cm Wall Thickness With total wall thicknesses of 16 to 20 cm, we offer significantly more stability, insulation, and energy efficiency than competitors who use only 10 cm—an absolute must for withstanding the forces of nature and retaining heat optimally.
Solid CLT Floor Slab Foundation Instead of a weak horizontal frame, we use a massive CLT (Cross-Laminated Timber) floor slab as a stable foundation. This guarantees maximum load-bearing capacity, prevents settling, and ensures absolute structural stability for decades.
Premium Tiled Flooring in every DERHOLZER Garden Sauna High-quality tiled floors are standard in every one of our garden saunas—hygienic, easy to clean, slip-resistant, and providing a sophisticated, lasting ambiance.
Individual 2D and 3D Garden Sauna Planning Each individual DERHOLZER garden sauna is precisely planned in 2D and rendered in photorealistic 3D—tailored exactly to your personal wishes and the specific conditions of your garden. This creates a tailor-made wellness paradise that blends perfectly into your surroundings.
Plug & Play with Full Factory Testing As a true plug-and-play sauna, each unit is fully assembled and undergoes a comprehensive functional test at our factory—ensuring everything runs perfectly from the moment it arrives, with zero surprises.
