How to Choose an Infrared Sauna for Your Home: Types, Benefits, Size & Buying Guide

An infrared sauna can turn part of your home into a private wellness space. Unlike traditional saunas that primarily heat the surrounding air, infrared saunas use infrared energy to warm the body directly.

For homeowners considering an infrared sauna, the biggest challenge is often not whether to buy one, but which type and size is right for their space, lifestyle, and budget.

From compact one-person models to larger family-sized cabins, infrared saunas are available in a variety of configurations. Some are designed for indoor use, while others are built for outdoor environments.

This guide explains the key factors to consider when choosing an infrared sauna for your home.

What Is an Infrared Sauna?

An infrared sauna is a sauna that uses infrared heaters to generate radiant heat.

Traditional saunas heat the air inside the cabin, which then warms your body. Infrared saunas work differently by using infrared wavelengths to transfer radiant energy directly to the body.

Infrared sauna systems can use different wavelength ranges, including:

• Near-infrared

• Mid-infrared

• Far-infrared

• Full-spectrum infrared

Some full-spectrum systems combine multiple infrared wavelength ranges in one sauna.

The type of infrared technology used is therefore one of the first things to consider when comparing different models.

What Are the Potential Benefits of an Infrared Sauna?

Many people choose infrared saunas as part of a home wellness routine.

Common reasons include:

1. Relaxation

The warmth of an infrared sauna can create a relaxing environment after a long day.

Many homeowners use their sauna as a dedicated space to disconnect from work, screens, and everyday distractions.

2. Sweating

Infrared heat can encourage sweating without requiring the extremely high air temperatures commonly associated with some traditional saunas.

This can make infrared saunas appealing to people who prefer a gentler heat experience.

3. Muscle Relaxation

Warmth can help people relax after physical activity or exercise.

For athletes and active homeowners, a home sauna can become part of a recovery and relaxation routine.

4. A Personal Wellness Space

One of the biggest advantages of having an infrared sauna at home is convenience.

Instead of driving to a gym, spa, or wellness center, you can create a dedicated sauna space in your own home.

However, infrared saunas should be viewed as a wellness and relaxation product rather than a replacement for medical treatment.

Infrared Sauna vs. Traditional Sauna

One of the most common questions is whether an infrared sauna is different from a traditional sauna.

The main difference is the way heat is generated.

Feature	Infrared Sauna	Traditional Sauna
Primary heat source	Infrared heaters	Sauna heater/stove
Heating method	Radiant heat	Heated air
Typical experience	Lower ambient temperature	Higher ambient temperature
Steam	Usually dry	Can be dry or humid depending on design
Installation	Often suitable for indoor home use	May require additional ventilation/electrical planning
Space options	Compact models available	Usually larger cabin options

Neither system is automatically right for every homeowner. Your choice should depend on the space available, preferred sauna experience, installation requirements, and budget.

Indoor vs. Outdoor Infrared Sauna

Another important decision is where you plan to install your sauna.

Indoor Infrared Sauna

An indoor infrared sauna can work well in spaces such as:

• Home gyms

• Bathrooms

• Master bedrooms

• Basements

• Wellness rooms

• Large walk-in areas

Indoor models can be particularly attractive when you want year-round access without going outside.

Saunasnet's current infrared collection includes several indoor models, including one-person, two-person, and larger configurations.

Outdoor Infrared Sauna

Outdoor infrared saunas can be installed in areas such as:

• Backyards

• Patios

• Pool areas

• Garden spaces

• Outdoor wellness areas

The major consideration is that an outdoor sauna needs to be designed and installed appropriately for outdoor conditions.

Weather exposure, foundation, drainage, electrical requirements, ventilation, and local installation conditions should all be considered before purchasing.

Saunasnet's current collection includes outdoor infrared models in two-person and four-person configurations.

What Size Infrared Sauna Do You Need?

Sauna size is one of the most important purchasing decisions.

1-Person Infrared Sauna

A one-person infrared sauna is designed primarily for individual use.

It can be a practical option when:

• You have limited space

• You normally use the sauna alone

• You want a dedicated personal wellness area

• You want to minimize the overall footprint

2-Person Infrared Sauna

A two-person infrared sauna provides more interior space while remaining relatively compact.

It may be suitable for couples or homeowners who want the option to use the sauna with another person.

3–4 Person Infrared Sauna

A larger sauna provides more room and can be more comfortable for households that want additional interior space.

It can also be useful if you prefer a less confined seating arrangement.

4–6 Person Infrared Sauna

Large infrared sauna cabins are designed for households that want more capacity.

Saunasnet currently lists the IR-NOVA ELITE 2 as a 4–6 person indoor infrared sauna.

When choosing a size, don't look only at the number of people advertised. Check the actual interior dimensions, seating arrangement, available floor space, doorway clearance, and electrical requirements.

Full-Spectrum Infrared Sauna vs. Single-Band Infrared Sauna

If you have been researching infrared saunas, you may have seen the term full spectrum infrared sauna.

Full-spectrum systems typically combine near-, mid-, and far-infrared wavelengths.

Different wavelength ranges are associated with different characteristics, which is why manufacturers may combine them into one system.

However, consumers should be careful with exaggerated health claims. The presence of multiple infrared wavelengths does not automatically mean that a sauna will provide specific medical benefits.

When comparing models, look at the actual heater configuration and technical specifications rather than relying only on marketing terminology.

What Should You Look for When Buying an Infrared Sauna?

Before purchasing, consider the following factors.

1. Sauna Size

Measure your available space first.

Don't forget to account for:

• Ceiling height

• Door opening

• Clearance around the sauna

• Assembly access

• Electrical access

A sauna may technically fit into a room but still be difficult to assemble if there isn't enough access space.

2. Indoor or Outdoor Installation

Determine where the sauna will be installed before choosing a model.

Indoor and outdoor saunas have different environmental requirements.

3. Infrared Technology

Check what type of infrared heaters are included.

If you specifically want a full-spectrum sauna, confirm that the product specification clearly identifies the wavelengths or heater configuration.

4. Electrical Requirements

Check the electrical requirements before ordering.

Depending on the model, you may need a specific voltage, amperage, outlet, or dedicated circuit.

If you are uncertain about your home's electrical capacity, consult a qualified electrician.

5. Materials and Construction

Look at the materials used for the sauna cabin.

Important considerations include:

• Wood construction

• Glass door quality

• Interior finish

• Heater placement

• Bench construction

• Door hardware

• Overall build quality

6. Controls

Consider how the sauna is controlled.

Depending on the model, features may include:

• Temperature controls

• Lighting controls

• Timer

• Digital display

• Audio or Bluetooth functionality

• Other smart controls

The best feature set depends on how you plan to use the sauna.

How Much Does an Infrared Sauna Cost?

The price of an infrared sauna can vary significantly depending on size, materials, heater technology, features, and whether it is designed for indoor or outdoor installation.

At the time of checking, Saunasnet's infrared collection lists models ranging from approximately $3,899 to $6,399 for several indoor models, while outdoor infrared models listed on the collection range from approximately $4,999 to $5,999. Prices and promotions can change, so buyers should check the current product page before making a purchase.

Which Infrared Sauna Is Right for You?

The right sauna depends largely on how you plan to use it.

Choose a 1-person model if:

You primarily use the sauna alone and have limited space.

Choose a 2-person model if:

You want a compact sauna but occasionally want to use it with another person.

Choose a larger model if:

You have enough space and want more room for multiple users or a more spacious interior.

Consider an outdoor model if:

You have a suitable backyard, patio, or other outdoor area and prefer to create a separate outdoor wellness space.

Consider full-spectrum technology if:

You specifically want a sauna that combines multiple infrared wavelength ranges and have confirmed the actual heater specifications.

How to Prepare Your Home for an Infrared Sauna

Before delivery, prepare the installation area.

Step 1: Measure the Space

Measure the width, depth, and height of the installation area.

Also measure the route from the delivery entrance to the final location.

Step 2: Check the Electrical Supply

Review the manufacturer's electrical requirements and make sure the installation location can support them.

Step 3: Prepare a Level Surface

The sauna should be placed on an appropriate, stable, level surface.

Step 4: Consider Ventilation

Although infrared saunas operate differently from traditional steam saunas, the installation area should still have appropriate airflow according to the manufacturer's instructions.

Step 5: Leave Enough Access Space

Avoid positioning the sauna so tightly against walls or furniture that maintenance or access becomes difficult.

Infrared Sauna Buying Checklist

Before placing an order, ask yourself:

• How many people will normally use the sauna?

• Do I want an indoor or outdoor sauna?

• How much floor space do I have?

• What type of infrared heater does the sauna use?

• Do I specifically want full-spectrum infrared?

• What electrical requirements does the sauna have?

• What materials are used?

• What features are included?

• How will the sauna be delivered?

• Does the manufacturer provide installation guidance?

• What warranty and after-sales support are available?

Answering these questions can make it much easier to narrow down your options.

Final Thoughts

An infrared sauna can be more than a piece of fitness equipment. For many homeowners, it becomes part of a broader home wellness routine.

The most important thing is to choose a sauna based on space, capacity, installation requirements, infrared technology, features, and long-term usability rather than focusing only on appearance or promotional pricing.

Whether you are looking for a compact one-person infrared sauna, a two-person home sauna, or a larger cabin for the whole household, comparing the specifications carefully can help you find a model that fits your home and lifestyle.

If you are exploring different infrared sauna options, you can review the current Saunasnet infrared sauna collection and compare the available indoor and outdoor models.
