Wood Options Ideal for New Hampshire Sauna Builds
Your choice of wood impacts not just the look of your sauna, but also its performance, longevity, and comfort. Below are our most popular options—each selected for its ability to handle moisture, heat, and long-term use in New Hampshire homes and businesses.
Cedar – Timeless, Aromatic, and Durable
Cedar is the most requested sauna wood for its natural fragrance, warm color, and exceptional resistance to warping or mold. Its rich tone and earthy aroma create an inviting spa-like atmosphere, making it ideal for ski cabins, basements, or outdoor saunas in snowy conditions.
Why choose cedar:
* Naturally resists mold, mildew, and bacteria
* Performs well in humid or dry climates
* Minimal upkeep with long-lasting durability
* Inviting scent and reddish tones enhance relaxation
-
Hemlock – Sleek, Neutral, and Hypoallergenic
For homeowners who prefer a clean, modern aesthetic, hemlock is a top pick. Its subtle grain and light tone pair perfectly with glass, stone, and contemporary interiors. Hypoallergenic and low in scent, it’s ideal for indoor sauna builds where a clean look is desired.
Why New Hampshire clients love hemlock:
* Low to no scent—perfect for sensitive users
* Smooth, even finish for modern styling
* Handles high temperatures without issue
* Works beautifully for indoor sauna rooms
Spruce – Bright, Efficient, and Eco-Friendly
Spruce brings a Scandinavian-inspired feel, with its pale tones and lightweight design. It offers excellent insulation, making it especially popular in compact homes, small wellness rooms, and lakeside cottages. Plus, spruce is sustainably sourced, making it a smart choice for eco-conscious homeowners.
Top reasons to choose spruce:
* Light, airy tones perfect for smaller spaces
* Strong insulation and energy efficiency
* Responsibly harvested and eco-friendly
* Complements modern and rustic interiors alike
Sauna Heating Systems That Match Your Lifestyle
Your heating system defines the sauna experience—whether you want the intense dry heat of a traditional sauna or the gentle warmth of infrared panels. At New Hampshire Custom Saunas, we install a variety of heater types, each chosen to fit your goals and property.
Electric Sauna Heaters – Reliable, Fast, and User-Friendly
Electric heaters are the most popular option for residential builds thanks to their ease of use, compact size, and programmable controls. Perfect for indoor saunas in homes, apartments, and gyms, they offer consistent performance and efficiency.
Benefits:
* Quick heat-up and digital timers
* Low-maintenance and long-lasting
* Great for small to medium sauna builds
* Energy-efficient options available
Wood-Burning Stoves – Rustic, Authentic, and Off-Grid Ready
For a traditional sauna experience, nothing beats a wood-burning stove. Ideal for backyards, cabins, or rural New Hampshire properties, these heaters create a rustic charm and deliver deep, even heat.
Why New Hampshire clients love wood heat:
* Perfect for off-grid or rural properties
* Creates a cozy, cabin-like ambiance
* Consistent, long-lasting dry heat
* Enhances outdoor and rustic settings
Infrared Sauna Panels – Gentle, Targeted, and Wellness-Focused
Infrared saunas are increasingly popular with health-conscious homeowners. Instead of heating the air, they warm your body directly, providing benefits like muscle recovery, detoxification, and circulation support at a lower, more comfortable temperature.
Highlights:
* Comfortable for longer sessions
* Operates at lower temps, gentle on airways
* Highly energy-efficient
* Popular for wellness rooms and spas

Hybrid Sauna Systems – The Best of Both Worlds
Hybrid systems combine infrared panels and traditional heat, giving you the flexibility to switch between styles—or even blend them in one session. They’re perfect for households or wellness facilities that want versatility.
Ideal for:
* Families with different heat preferences
* Commercial spas offering multiple sauna experiences
* Long-term flexibility in one build

* Indoor saunas: $7,000 – $12,000
* Outdoor saunas: $9,000 – $18,000

What should I think about when designing a custom sauna?
Key decisions include:
* Available space (indoor room, basement, or outdoor yard)
* Heat source (electric, wood-burning, infrared, or hybrid)
* Seating capacity and layout
* Wood type (cedar, hemlock, spruce, or others)
* Ventilation, electrical setup, and safety needs
* Style choices (lighting, windows, glass doors, finishes)
At New Hampshire Custom Saunas, we guide you through each step with design consultations and 3D renderings so your sauna fits your lifestyle, property, and wellness goals perfectly.
What are the benefits of owning a sauna at home?
A custom sauna brings both physical and mental wellness benefits right into your home. Regular sauna use may help reduce stress, improve sleep, support circulation, ease sore muscles, and encourage detoxification. For New Hampshire residents, a home sauna also provides year-round comfort—helping you warm up after skiing, recover from workouts, or simply relax after a long day.
Because each sauna is tailored to your available space and preferences, you’ll enjoy maximum comfort, performance, and long-term value without relying on a gym or spa membership.
Can I add features like lighting, audio, or glass panels?
Absolutely. We offer a wide range of custom upgrades to enhance your sauna experience:
* LED mood and ambient lighting
* Chromotherapy (color therapy) lights
* Bluetooth or built-in sound systems
* Salt wall panels for air quality and aesthetics
* Custom glass doors or viewing windows
* Digital smart controls with remote operation
All features are discussed and planned during the design stage to ensure seamless integration.
Can you install pre-built saunas?
Yes. If you’ve already purchased a prefab or pre-built sauna kit, our team provides professional installation. We handle foundation preparation, electrical hookups, ventilation, and system testing to ensure safe, efficient performance.
Not sure which sauna to buy? We also offer pre-purchase consultations to make sure the model you choose works with your space, power supply, and expectations.
Are saunas safe to use regularly?
Yes—when properly installed, saunas are safe for most healthy adults. We build with heat- and moisture-rated materials, GFCI-protected circuits, and proper ventilation systems. We also provide you with operational guidance after installation for safe everyday use.
As always, consult your doctor before beginning sauna use if you are pregnant, have cardiovascular issues, or other medical conditions.
How long does sauna installation take?
Most custom-built saunas are installed within 2–5 days, depending on complexity, site conditions, and whether electrical work is required. Pre-built sauna kits can often be installed in one day if the site is properly prepared.
We’ll provide you with a clear timeline after finalizing the design and keep you informed throughout the process.
How does the type of wood affect sauna pricing?
Wood selection influences both aesthetics and cost. Common sauna woods include:
* Cedar: A premium wood that’s durable, naturally resistant to mold, and aromatic. Long-lasting but at a higher price point.
* Hemlock: A smooth, knot-free, scent-free option—less expensive than cedar, while still highly durable.
* Spruce: Budget-friendly, eco-conscious, with excellent insulation. Ideal for modern or compact builds.
Higher-end woods provide longer durability and visual appeal, but we’ll walk you through pros, cons, and pricing so you can make the right decision for your project and budget.
Are infrared saunas better than traditional saunas?
Both have distinct benefits:
* Traditional saunas (electric or wood-burning) create high, dry heat, producing a deep sweat and a classic sauna experience.
* Infrared saunas use radiant heat panels to warm the body directly, operating at lower air temperatures but often providing deeper muscle relaxation and recovery.
Many clients choose hybrid systems, which allow both options in one unit—ideal for families or businesses offering varied experiences.
