Looking into Installing a Sauna in Your Home? Things to Consider

17 February 2025

With a sauna, you can easily relax, de-stress, and detox.

But installing it in your home is a significant commitment to make. And so, it requires careful thought and planning. Here’s what to consider.

Choosing the Right Sauna Type

You’ll have two main home sauna options: traditional or infrared saunas.

Key Differences

While both sauna types promote sweating and relaxation, the user experience differs significantly:

Traditional Saunas

Heat the air to 160°F-212°F

Use steam from water on hot rocks to increase humidity
Provide an immersive, enveloping heat
Allow for social experience with others

Require 20-30 minutes to preheat

Infrared Saunas

Use infrared light to heat your body directly (not the air)

Typically max out at 140°F
Feel more like targeted heat therapy
Best for 1-2 person use

Heat up more quickly

The traditional sauna replicates centuries of Finnish sauna culture. The steam, scents from wood, and intense heat create a special social experience. Infrared saunas provide more direct body warming that feels therapeutic.

Indoor vs Outdoor Sauna Placement

Based on climate, space and aesthetics, you can decide on where to install them.

Indoor Sauna Benefits

More private
Usable year-round

Close access from home
Less planning is needed per use

Outdoor Sauna Benefits

Creates special escape and journey
Immersive nature experience
Can be used for star gazing at night

The sauna session feels more intentional

If choosing an outdoor sauna, weather protection and excellent insulation become critical. The sauna must withstand all weather while maintaining safe function.

Custom-Built vs Prefabricated Saunas

You can buy a premade sauna kit or hire contractors to custom-build your sauna.

Prefab Sauna Considerations

Lower cost
Easy to install

Limited in layouts and materials

Custom-Built Sauna Considerations

Design it just for you

Choose layout, materials, features
Higher cost to build
Permits often required

Prefabricated saunas provide the most cost-effective and convenient option. But custom-built saunas allow you to personalize the details to suit your space and preferences.

Choosing the Right Sauna Location

The sauna location impacts convenience, privacy, and the user experience.

Key Indoor Sauna Placement Considerations

Ventilation:Excellent ventilation is mandatory for safety and comfort. Systems should exchange indoor and outdoor air without drafts.

Moisture Control:Proper humidity levels must be maintained inside and outside the sauna to prevent mold and moisture damage.
Electrical:Locate near an existing high-capacity circuit to avoid expensive new wiring.
Journey:Place in a sequence that provides an intentional transition into relaxation.

Convenience:Ensure household members can access the sauna easily when desired.

Key Outdoor Sauna Placement Considerations

Weather Protection:Overhangs, durability and insulation allow it to withstand the weather.
Accessibility:Near home for convenience but private. Clear walking paths prevent injury.

Scenery:Consider views from within the sauna and star gazing capability.
Privacy:Design a peaceful escape that feels secluded from neighbors.
Security:Ensure the sauna is protected when not occupied.

Take time to think about your lifestyle goals for the sauna. Then determine placement based on who will use it and when, your climate, changing seasons and more.

Electrical Requirements and Safety

Saunas require proper electrical setup for power, safety, and efficiency.

Infrared Sauna Electrical Considerations

While infrared saunas use less power, they rely on clean stable power to work correctly. Install a dedicated outlet meeting the manufacturer’s specifications.

Traditional Sauna Electrical Considerations

Traditional saunas require specialized 220-240 volt wiring with grounding. A licensed electrician must install the dedicated high-capacity circuits to meet building codes.

Essential Electrical Safety Precautions

Electrical safety is critical given heat, steam and risk of electric shock. Consider:

Waterproof interior outlets

Outdoor outlets with GFCI capability
Moisture sensors to disable power if needed
Light switches located outside the sauna

Signage indicating safety protocols

Consult an electrician experienced in sauna installation to ensure a safe system.

Sauna Building Materials and Construction

The materials impact the safety, comfort, longevity and overall sauna experience.

Sauna Wood Types

Traditional saunas use wood benches, wall paneling and ceiling finishes. Common wood options include:

Cedar Wood

Exceptional durability
Aromatic scent
Naturally resists mold and insects

Handles temperature fluctuations

Hemlock Wood

Very durable

Light color
Costs less than cedar

Spruce Wood

Light color
Fresh, appealing scent
Requires sealants for protection

Always use wood types approved for sauna use at hot temperatures. Ensure any sealants meet safety standards when heated.

Insulation and Vapor Barriers

Saunas require special insulation designed for extreme temperature differences, humidity and steam. Recommended insulation options include:

Mineral wool

Ceramic fiber
Perlite board
Foil-faced fiberglass specifically rated for saunas

Vapor barriers are also essential to prevent moisture from damaging walls, ceilings or framing. Consult local building codes to ensure compliant vapor barrier installations.

Heating System Options

The heating system impacts cost, maintenance, environmental impact, convenience and the overall experience.

Types of Sauna Heaters

Electric Heaters

Convenient and adjustable
Rely on home electric system

Higher operating costs

Wood Stoves

Burning wood releases moisture and aroma

Lower costs with accessible wood
Higher maintenance

Gas Heaters

Heat up quickly
Lower operating costs
Must have ventilation to avoid carbon monoxide poisoning

Hybrid Heaters

Use electric and wood heat
Lower costs than electric alone

Also consider heat-up times, maximum temperatures and safety features like timers or overload protection. Choose the heating system aligned with your lifestyle, preferences and budget.

Ventilation and Airflow System

Every sauna absolutely requires proper ventilation for safety, cleanliness and comfort.

Why Ventilation Matters

Good ventilation:

Removes moisture to prevent mold
Provides fresh air circulation

Distributes heat evenly
Controls humidity for comfort
Refreshes stale air

Without it, safety and hygiene issues will result quickly.

Installing Intake and Exhaust Vents

Work with HVAC experts to install vents properly based on the sauna layout.

Intake ventsbring in fresh air. Place them lower on the wall to maintain cooler air entering.
Exhaust ventsshould be higher up to remove hot air and steam.

The positioning allows continuous airflow without letting in cold drafts or losing heat energy.

Health, Hygiene, and Safety Considerations

It’s crucial to prioritize health and safety when planning your home sauna.

Temperature, Humidity and Time Limits

The combination of heat and humidity impacts how safe and enjoyable the sauna will be:

160°F to 185°F is comfortable for most healthy adults
10-20 minute sessions prevent overheating or dehydration
Limit humidity to 10-15% inside the sauna

Provide hygrometers and thermometers to monitor

Fire Hazards and Precautions

Saunas demand strict precautions given heating elements and steam.

Only use certified heaters made specifically for saunas
Install timers to prevent accidental overheating
Place wood-burning stoves away from benches and walls

Ensure functioning smoke and carbon monoxide detectors
Store all flammables away from the sauna
Provide a fire extinguisher and emergency first aid kit

Prioritizing health is also key. Consult your doctor about safe sauna use if pregnant, elderly, having medical conditions or on medications.

Accessories and Upgrades

The right accessories transform a basic sauna into a customized wellness retreat. Fun additions could include:

Interior Decor Upgrades

Chromotherapy lighting (colored LED lights to set the mood)
Heated flooring for feet
Towel warmers

Speakers for music
Essential oil diffuser
Magazines or sauna buckets and ladle

Comfort and Convenience Accessories

Luxury towels
Headrest pillows

Ergonomic floor mats
Hygrometer / thermometer
Sand timer

Waterproof clock
Beverage cooler

When equipping your sauna, look for accessories specially rated for sauna use at hot temperatures. This helps avoid damage or safety hazards.

Sauna Maintenance

Performing regular sauna maintenance prevents problems and keeps it operating safely.

Cleaning and Disinfecting

Wash benches, flooring, and walls with disinfectants regularly
Use mildew removers if mold spotted
Provide floor drain to remove water
Replace bamboo mats annually

Heater Inspections

Hire technicians to inspect heaters annually
Ensure heating elements fully dry before use
Make repairs immediately if issues arise

Review your sauna manual for the suggested cleaning schedule and heater precautions.

Cost to Build and Operate

Understand the upfront and ongoing costs when budgeting for your home sauna.

Upfront Sauna Costs

According to the National Kitchen and Bath Association, you can expect to invest:

$5,000 to $7,000 installedfor basic portable infrared saunas
$7,000 to $15,000 installedfor precut kit saunas
