Best Wood Types for Sauna Construction
Choosing the right wood is essential for creating a sauna that maintains both form and function. Below are our most popular and reliable options:
Cedar: The Gold Standard for Saunas
Cedar remains the top choice for custom sauna builds—and for good reason. Naturally resistant to moisture, warping, and insects, cedar performs exceptionally well in high-humidity, high-temperature environments. Its rich, aromatic scent and warm red hue add a calming spa-like ambiance to any indoor or outdoor setting.

Hemlock: Sleek, Smooth & Hypoallergenic
If you're after a more modern aesthetic, hemlock delivers a clean, knot-free appearance and smooth grain. It's a great choice for clients who prefer a neutral tone or are sensitive to aromatic woods. Hemlock is durable, stable under heat, and offers a quiet elegance perfect for both home and commercial sauna installations.
Why Choose Hemlock:
*
Hypoallergenic and low-scent
*
Minimal grain for contemporary designs
*
Stable and heat-resistant

Pairs well with glass and metal elements

Frequently Asked Questions
Whether you're new to sauna ownership or exploring the idea of building one at home or for your business, we've compiled a comprehensive FAQ to answer the most common and most important questions our clients ask. These insights are designed to help you make informed decisions and understand exactly what to expect when working with Seattle Custom Sauna Builders.
Traditional vs. Infrared Sauna: What's the Difference?
A traditional sauna uses either electric or wood-burning heaters to warm the air, which then heats your body through convection. Temperatures typically reach 150–190°F and produce a dry, hot environment. A modern infrared sauna, on the other hand, uses infrared light to directly heat your body at lower air temperatures (110–130°F), offering a more gentle experience that penetrates deeply into muscles and tissues.
Infrared saunas are preferred by those looking for therapeutic benefits like detoxification, relaxation, or muscle recovery, while traditional saunas appeal to purists who enjoy high heat and intense sweating.
How much space is needed to install a custom sauna?
Saunas can be tailored to fit almost any space. The smallest models typically require as little as 4'x4', which is perfect for one or two people. Larger saunas for families or commercial use can take up an entire room or exterior structure. We assess your space during the consultation phase and create a design that maximizes functionality without sacrificing comfort.
Do I need a permit to build a sauna in Seattle?
Yes, in many cases. If you're building an outdoor sauna or converting a room in your home, local codes may require electrical permits, ventilation approvals, or structural clearances. Our team handles all necessary permits to ensure your sauna complies with Seattle building regulations. We'll walk you through the process and manage all documentation.
What materials are best for sauna interiors?
We recommend high-quality, thermally stable woods like:
Western Red Cedar: Aromatic, moisture-resistant, and ideal for most sauna builds.
Hemlock: Sleek, hypoallergenic, and modern in appearance.
Spruce: Light-colored, cost-effective, and traditionally used in Nordic designs.
These woods are naturally insulating and stay cool to the touch, even in high heat. They also resist warping and cracking over time, ensuring longevity and safety.
Where does Seattle Custom Sauna Builders offer services?
We proudly serve the greater Seattle area and surrounding communities, including Bellevue, Kirkland, Redmond, Issaquah, Shoreline, West Seattle, Capitol Hill, Queen Anne, Mercer Island, and even select locations in Tacoma. If you’re unsure whether we cover your area, give us a call at (206) 207-5599—we’re happy to confirm and may still be able to accommodate your project.
How long does it take to install a sauna?
The full installation process typically takes 1 to 2 weeks for residential indoor saunas, once materials are ready. Outdoor or commercial saunas may take longer due to additional permitting or site prep. We provide a full project timeline up front and coordinate everything from design to final walk-through.
Are saunas energy efficient?
Yes. Modern electric heaters and infrared panels are designed with energy efficiency in mind. Most residential saunas cost less than $1 per hour to operate. Proper insulation, ventilation, and timers help reduce waste and optimize performance. We also offer energy-saving upgrades like LED lighting and smart controls.
Can I customize the features in my sauna?
Absolutely. At Seattle Custom Sauna Builders, we offer a range of custom options including:
Bench layouts (L-shaped, tiered, or open seating)
Glass fronts and windows
LED and chromotherapy lighting
Built-in audio systems
Custom heater placement
Salt walls or aromatherapy dispensers
Your sauna will be designed to match your wellness goals, design style, and daily usage needs.
How often should I use my sauna?
Most users benefit from sauna sessions 3 to 5 times per week, depending on their personal health and goals. Sessions can range from 10 to 30 minutes. Always hydrate before and after use, and consult a medical provider if you have underlying conditions.
