Online wood retailers
Specialty online retailers have emerged as a convenient solution for sourcing sauna-grade wood, offering a curated selection that local hardware stores often lack. Sauna.com, for instance, provides pre-cut cedar kits with tongue-and-groove profiles optimized for moisture resistance, while Northern Lights Cedar specializes in sustainably harvested Western Red Cedar planks in thicknesses ranging from ¾” to 1½”—ideal for walls and benches. Both platforms include detailed installation guides, though Northern Lights’ wood is priced 15–20% higher due to its Forest Stewardship Council (FSC) certification.
When ordering online, prioritize retailers offering kiln-dried wood with moisture levels below 10%, as this minimizes warping during temperature fluctuations. Woodworkers Source stands out for its custom milling services, allowing buyers to specify dimensions down to 1/16” increments, though lead times average 3–4 weeks. Conversely, SaunaFin bundles pre-dimensioned thermo-treated aspen—a lightweight, resin-free option—with vapor barrier kits, making it a one-stop solution for DIY builders. Note: Thermo-treated woods cost 30–40% more than untreated varieties but offer superior dimensional stability.
A critical factor often overlooked is shipping logistics. SaunaLife mitigates this by partnering with regional freight carriers to deliver full-pallet orders (typically 500–800 board feet) within 7–10 days, with flat-rate fees ranging from $250–$450 depending on zone. Smaller retailers like Cedar Country Lumber use parcel shipping for orders under 100 board feet but charge per lineal foot, which can inflate costs for thicker planks. Pro tip: Consolidate purchases to qualify for pallet rates, as individual piece shipping rarely aligns with sauna project scales.
For those prioritizing exotic or rare woods, Exotic Lumber Zone sources thermally modified hemlock and Siberian larch, though these options are best suited for accent pieces due to higher resin content. Their wood is treated to withstand temperatures up to 220°F, but compatibility with sauna heater placement requires careful planning. Always request a sample before committing to large orders, as color variations in exotic species can be pronounced.
Finally, consider the return policy before finalizing a purchase. Saunacore Supplies offers a 30-day return window on unopened wood packages, while most competitors limit refunds to damaged goods only. Given the precision required in sauna construction, this flexibility can save significant costs if measurements are miscalculated. Pair online purchases with digital planning tools like Sauna Planner Pro to ensure material quantities align with design specifications before ordering.

Specialty sauna wood stores
When sourcing wood from a specialty store, consider the thickness and grade of the planks. Standard sauna wall planks range from 1/2 inch to 3/4 inch in thickness, balancing insulation and structural integrity. Ceiling planks, exposed to higher temperatures, may require thicker cuts or additional treatment. Specialty stores often offer pre-cut kits tailored to specific sauna dimensions, simplifying installation for DIY enthusiasts. However, custom orders are common for unique designs or larger saunas. Prices vary widely—expect to pay $5 to $15 per square foot for high-quality sauna wood, with exotic options like thermally modified pine commanding a premium. Always verify if the wood has been kiln-dried to minimize moisture content, reducing the risk of shrinkage.
One of the standout advantages of specialty sauna wood stores is their ability to address niche needs. For example, if you’re building a mobile or outdoor sauna, they can recommend woods treated for weather resistance or lighter materials for portability. Some stores even offer accessories like benches, backrests, and headrests crafted from matching wood, ensuring a cohesive look. Additionally, they often stock complementary products such as sauna heaters, thermometers, and hygrometers, making them a one-stop shop for builders. For those prioritizing sustainability, many specialty stores provide FSC-certified or locally sourced wood, aligning with eco-conscious values.
While specialty stores offer unparalleled expertise, they may not be the most cost-effective option for all projects. If budget is a concern, compare their offerings with those of general lumberyards or online retailers, though be cautious of lower-quality wood that may not perform well in sauna conditions. To maximize value, inquire about bulk discounts or off-cut bundles for smaller projects. Finally, ask about maintenance tips—specialty stores often advise on finishing techniques, such as using natural oils or sealants that withstand heat without emitting toxins. By leveraging their knowledge and curated selection, specialty sauna wood stores ensure your dry sauna not only functions optimally but also stands the test of time.

Hardware stores with sauna wood
For those building a dry sauna, hardware stores are a logical starting point for sourcing wood. Major chains like Home Depot, Lowe’s, and Menards often carry cedar and hemlock, two popular sauna wood options. Cedar, with its natural resistance to decay and pleasant aroma, is a top choice, while hemlock offers a lighter color and smoother texture. These stores typically stock lumber in standard dimensions (e.g., 1x4, 1x6), making it easy to calculate quantities for walls, benches, and ceilings. However, availability can vary by location, so calling ahead to confirm stock is advisable.
While hardware stores provide convenience, there are limitations to consider. The wood sold here is often untreated and may not meet the specific moisture and heat resistance standards required for saunas. For instance, kiln-dried wood with a moisture content below 10% is ideal to prevent warping, but hardware stores rarely specify this detail. Additionally, the selection may lack specialty cuts or lengths needed for custom sauna designs. DIYers should also be cautious of knots and imperfections in lower-grade lumber, which can expand and crack under sauna conditions.
For those prioritizing quality and expertise, specialty sauna retailers or lumberyards are a better bet. However, hardware stores remain a cost-effective option for straightforward projects. To maximize success, buyers should inspect boards for straightness, minimal knots, and consistent color. Purchasing extra material (10-15% more) accounts for cuts and mistakes. Finally, sealing the wood with a non-toxic finish after installation can enhance durability, though this step is optional depending on the wood type and desired aesthetic.
In summary, hardware stores offer accessibility and affordability for sauna wood but require careful selection. By focusing on cedar or hemlock, verifying dimensions, and inspecting quality, builders can find suitable materials for basic saunas. For more complex or high-end projects, however, specialized suppliers may be necessary to ensure long-term performance in the demanding sauna environment.

Sustainable wood sourcing options
Choosing sustainably sourced wood for your dry sauna isn't just an ethical decision—it’s a practical one. Wood from responsibly managed forests resists warping and cracking under heat, ensuring longevity. Look for certifications like FSC (Forest Stewardship Council) or PEFC (Programme for the Endorsement of Forest Certification) when purchasing. These labels guarantee the wood comes from forests managed to meet environmental, social, and economic standards. Avoid uncertified sources, as they may contribute to deforestation and habitat destruction.
If you’re hands-on, consider reclaiming wood from old barns, warehouses, or demolition sites. Reclaimed wood not only reduces demand for new timber but also adds character to your sauna with its weathered texture and unique grain patterns. Ensure the wood is free of chemicals like lead paint or preservatives, which can release toxins under heat. Cedar and hemlock are popular choices for saunas due to their natural resistance to decay, but reclaimed oak or spruce can work if properly treated and sealed.
For those prioritizing carbon footprint, locally sourced wood is a smart choice. Transporting materials over long distances increases emissions, so seek out regional suppliers or mills. Ask about the wood’s origin and whether it’s harvested within a 100-mile radius of your location. Local wood is often fresher, reducing the risk of drying defects that can occur during long-distance shipping. Plus, supporting local businesses fosters community sustainability.
Bamboo, though not a traditional choice, is a rapidly renewable alternative to hardwoods. It matures in 3–5 years compared to decades for trees like cedar. Bamboo’s natural strength and moisture resistance make it suitable for sauna interiors, particularly walls and benches. However, ensure it’s sourced from sustainable plantations, as some bamboo farming practices can harm ecosystems. Combine bamboo with certified hardwood for structural elements to balance sustainability and durability.
Finally, consider thermally modified wood, a process that uses heat to alter wood’s cellular structure, enhancing its stability and resistance to moisture. This method extends the lifespan of less durable species, reducing reliance on high-demand hardwoods. Brands like ThermoWood or Platowood offer pre-treated options ideal for sauna environments. While the initial cost may be higher, the reduced maintenance and longer lifespan offset expenses over time. Always verify the treatment process aligns with eco-friendly standards.
