How to Choose the Right Infrared Sauna

The right infrared sauna depends on your available space, how many people will use it, the type of infrared experience you prefer and which features matter most to you. Our product specialists can help you compare Sunlighten models in person, but these are some of the most important factors to consider.

Sauna Size & Capacity

Consider where the sauna will be installed and how many people will typically use it. Sunlighten offers personal and multi-person sauna options, allowing you to choose a cabin size that fits both your available space and how you plan to use it.

Infrared Technology

Different Sunlighten collections offer different infrared experiences. When comparing models, consider whether you want far-infrared or full-spectrum infrared technology, the temperatures you prefer and any additional wellness features that are important to you.

Red Light Therapy

If red light therapy is important to you, compare models and collections that integrate red light features with the infrared sauna experience. Our team can explain the available options and help you determine which combination of technologies best matches what you're looking for.

Installation & Electrical Requirements

Installation requirements vary by sauna model and size. Many Sunlighten saunas require either a dedicated 110V 20-amp circuit or a 220V 20-amp circuit, depending on the model. Before purchasing, consider the planned location, available space, flooring, access and electrical requirements. Our team can help you confirm the specific electrical requirements for your Sunlighten sauna before delivery so you can have the space properly prepared for installation.

Visit one of our showrooms to see select Sunlighten saunas in person, compare models and sizes, and speak with a product specialist about the best option for your home.

How hot do infrared saunas get?

Sunlighten infrared sauna temperatures vary by collection, model and operating conditions. Depending on the model, some Sunlighten saunas can reach approximately 160–170°F, while many people choose to enjoy their sauna sessions at lower temperatures based on personal preference. Unlike traditional saunas that primarily heat the surrounding air, infrared saunas use infrared energy to deliver a different heating experience. Our team can help you compare the temperature capabilities and heating technologies of each Sunlighten collection in person.

How much space do I need for an infrared sauna?

The amount of space needed depends on the sauna model and the number of people it is designed to accommodate. In addition to the dimensions of the sauna itself, Sunlighten recommends allowing approximately 4 inches of clearance along the sides and back of the sauna and 6 inches of clearance above it. You should also consider ceiling height, door clearance, electrical access and enough space in front of the sauna for comfortable entry and exit. Our team can help you review the dimensions and installation requirements of a specific Sunlighten model before purchase.

What electrical requirements does a Sunlighten sauna need?

Electrical requirements depend on the specific Sunlighten model. Many models require either a dedicated 110V 20-amp circuit or a 220V 20-amp circuit. Because requirements can vary by model, we recommend confirming the electrical specifications of your chosen sauna before installation. Our team can provide the requirements for your specific model so your space can be properly prepared before delivery.

What is the difference between far-infrared and full-spectrum infrared saunas?

Far-infrared saunas use far-infrared wavelengths to provide an infrared sauna experience, while full-spectrum saunas incorporate multiple infrared wavelengths. Sunlighten offers different technologies across its sauna collections, so the best choice depends on the type of sauna experience and features you prefer. Our team can demonstrate the differences and help you compare available models in person.
