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 builders—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.
Benefits of Cedar:
*
Naturally antibacterial and mildew-resistant
*
Long-lasting without chemical treatment
*
Aromatic and inviting
*
Ideal for traditional or luxury designs
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
Spruce: Bright, Clean & Eco-Friendly
Spruce offers a natural, Scandinavian-inspired aesthetic with a light, airy tone. It’s an excellent material for minimalists or those seeking a soft, welcoming environment. In addition to its visual appeal, spruce is known for its sustainability and structural strength.
Top Features of Spruce:
*
Light, bright color palette
*
Eco-conscious sourcing
*
Smooth finish and soft visual texture

Excellent thermal insulation properties

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 Saunas.
Do sauna designs vary depending on the home and location?
Yes. Sauna projects are often designed around the layout of the home, climate conditions, ventilation needs, and overall design style of the property. Homeowners researching projects in different regions sometimes compare layouts and material choices used in areas such as Orange County or Chicago where architectural styles, weather conditions, and available space can vary significantly.
Are infrared saunas proven to be healthy?
Infrared saunas have been the subject of growing research in recent years, with studies suggesting a variety of potential health benefits. While more long-term studies are still ongoing, many users and wellness professionals report noticeable improvements in:
Muscle recovery and joint pain relief
Improved circulation and cardiovascular support
Stress reduction and better sleep
Detoxification through sweating
Skin clarity and elasticity
Infrared saunas work by gently heating the body directly, rather than raising the air temperature like traditional saunas. This allows for longer, more comfortable sessions—making them ideal for daily use or for those sensitive to high heat.
As with any wellness technology, results vary by individual. If you have a medical condition, consult your healthcare provider before beginning infrared sauna therapy.
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 do you 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.
Do you work with homeowners outside the Seattle area?
Do you work with homeowners outside the Seattle area?
Most projects are located throughout Seattle and the surrounding Pacific Northwest region, but some homeowners also reach out while relocating or researching sauna projects in other climates along the West Coast. In certain cases, we may be able to provide general guidance or recommend professionals for projects in areas such as Portland, Northern California, or Southern California depending on the project type and location.
How long does it take to install a sauna?
The full sauna installation and building 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.
Can I customize the features in my sauna?
Absolutely. At Seattle Custom Saunas, 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.
What’s included in a custom sauna quote?
Every quote from Seattle Custom Saunas includes design consultation, material options, heating system recommendations, installation timeline, and complete pricing breakdown. We tailor each estimate to your specific project goals, so you know exactly what to expect—no hidden costs, no surprises.
How does climate affect sauna design in different regions?
Climate can influence everything from ventilation planning and material selection to insulation, moisture management, and overall sauna performance. Homeowners researching projects in different environments sometimes compare sauna designs in regions such as Denver, Salt Lake City, or Las Vegas where elevation, humidity, and seasonal weather conditions may affect how the space is planned and built.
