Sauna Safety Starts with Smart Material Choices
At Leisure Pools & Spas, your comfort and safety come first. Many homeowners invest in a sauna to relax, detox, and improve overall wellness — but not all saunas are built the same. The materials used inside your sauna can significantly impact air quality, durability, and long-term performance.
Infrared heat works by warming the body directly rather than simply heating the surrounding air. Because this energy penetrates surfaces — including the interior wood of the sauna — the type of wood used matters more than many people realize.
That’s why understanding sauna construction materials is essential when selecting the right system for your home.
Why Sauna Wood Matters
Certain woods naturally contain oils and compounds that are harmless in construction settings but may release strong aromas or airborne compounds when exposed to sustained heat. In enclosed sauna environments, these emissions can affect sensitive individuals, particularly those prone to allergies or respiratory concerns.
Some wood species contain natural terpenes — organic compounds that help trees resist insects and decay. When heated, these compounds can become more noticeable in scent and intensity. While many people enjoy the aroma of traditional cedar saunas, others may prefer low-resin, low-aroma wood options for a cleaner breathing experience.
For this reason, many modern infrared sauna manufacturers utilize woods such as aspen or other low-resin hardwoods, which are known for:
Minimal natural oils
Low odor release when heated
Smooth, splinter-resistant surfaces
Clean, furniture-grade appearance
Choosing the right interior wood contributes to both comfort and peace of mind.
Understanding Common Sauna Woods
Different wood species are used in sauna construction for structural, aesthetic, or aromatic reasons. Each type has distinct characteristics, here is a list of wood and their health effects:
- Alder – Dermatitis associated with black alder & decrease in lung function with red alder
- Aspen – No health effects reported
- Beech – Dermatitis, Woodcutter’s disease, rhinitis, asthma, nasal cancer
- Birch – Dermatitis
- Cedar – Asthma, Dermatitis, sensitizer, decrease in lung function, eye irritation and Conjunctivitis, Rhinitis
- Douglas Fir – Contact eczema, decrease in lung capacity
- Other Firs (grand, balsam, silver, alpine) – Skin irritation, dermatitis, rhinitis, asthma, possible decrease in lung function
- Hemlock – Skin irritation, decreased lung function
- Larch – Dermatitis from European larch, no reports with western larch
- Mahogany – Dermatitis, sensitizer
- Maple – Rhinitis, asthma, Maple Bark Strippers’ Disease (mould spores in bark)
- Oak – Nasal cancer
- Pine – Skin irritation, contact dermatitis, Wood-Pulp Workers’ Disease (mould in bark), rhinitis, and asthma
- Poplar – Contact dermatitis (with sawdust contact), rhinitis
- Rosewood – Eczema, allergic contact dermatitis
- Spruce – Skin irritation, Wood-Pulp Workers’ Disease (mould spores in bark), decrease in lung function
- Teak – Toxic, dermatitis, sensitizer
- Black Walnut – Skin irritation, rhinitis, possible asthma
- Yew – Irritation of skin, dermatitis, toxic
For homeowners with sensitivities, low-resin hardwoods are often preferred in infrared sauna environments where heat penetrates deeper into materials.
Built for Performance & Durability
Beyond air quality considerations, sauna construction quality matters. Thicker, furniture-grade wood panels provide:
Greater structural strength
Improved insulation performance
Reduced warping over time
Enhanced longevity
At Leisure Pools & Spas, we guide our customers toward sauna options built with durable materials designed for long-term reliability — not mass-produced shortcuts.
Making an Informed Sauna Decision
The right sauna should deliver relaxation and wellness benefits without compromise. When selecting a sauna, consider:
Wood species used inside the cabin
Thickness and durability of panels
Construction quality and craftsmanship
Heating technology and safety certifications
Our team helps you evaluate these factors so you can choose a sauna that fits your lifestyle and comfort preferences.
