Core Features

Heat and Light, Engineered for Recovery

A four-person infrared sauna with 100% Canadian hemlock, ultra-low EMF shielding, clinical-grade red light at a comfortable distance, and Bluetooth speakers.

Heat and Light, Engineered for Recovery

Premium Wood Construction

All wood used is non-resinous 100% Canadian hemlock wood (no plywood).

Ultra Low EMF/ELF/RF Levels

We use grounded heaters, Faraday shielding, and minimal RF. In our testing, EMF levels are below 2 mG and ELF below 7 v/m.

Clinical-Grade Red Light at Safe Distances

Unlike most red light panels that require close proximity (6 inches or less), the red light panel built into this sauna delivers clinically effective irradiance at comfortable distances where EMF exposure is minimized.
At 12 inches you receive 38.20 mW/cm², at 24 inches 36.39 mW/cm², and even at 36 inches away you still get 29.33 mW/cm²—all while enjoying your heat therapy session.
Includes 5 therapeutic wavelengths (630 nm, 660 nm, 810 nm, 830 nm, 850 nm) for optimal photobiomodulation.

Bluetooth Speakers

Built in Bluetooth speakers with wooden covers (instead of standard plastic, reducing VOC concerns)

The Details

Room to Move, Details to Match

From removable benches to an 84-inch cabin with a grounding port, every detail adapts the space to how you recover.

When we moved into the Miami house, creating an at home wellness space was one of the first things on my list and the main thing I wanted was a sauna. I spent way too much time researching before finally choosing @heavenlyheatsaunas. Their saunas are low EMF, non-toxic, and designed without glues, plywood, or anything that off-gasses, which was really important to me.

Understanding Sauna Heat & Temperature

Our Tip

Listen for a small "click" sound - this tells you when heaters are cycling on or off as they reach the set temperature. Don't touch heaters to check.

Your Investment Is Protected

Understanding Sauna Heat & Temperature

Many customers ask about exact heat-up times and maximum temperatures. Here's why those numbers vary - and why they matter less than you might think.


Why we don't list specific max temperatures

Your sauna's ambient temperature and available power draw significantly impact both heat-up time and maximum temperature - factors outside our control. More importantly, focusing on "max temp" misses how infrared therapy actually works.

How to use your sauna effectively

Get in when the sauna reaches 90-110°F and enjoy your session as it continues heating. This keeps the heaters running continuously, maximizing your infrared exposure.

How We Stack Up

Infrared Sauna & Traditional Sauna

With traditional Finnish sauna research making headlines, it's natural to wonder how infrared compares. The short answer: they're different modalities with different benefits - not better or worse, just different.

Questions You Should Be Asking

Questions you should be asking before you buy any sauna - and how we answer them

Most buyers don't know what to ask. These are the questions that actually matter.

What is an Infrared Sauna?

Infrared saunas use far infrared heaters to emit radiant heat, directly warming the body without significantly heating the surrounding air. This results in a more gentle and comfortable heat compared to traditional saunas. The more comfortable environment allows users to experience more sweating. You don’t need to worry about ‘not feeling the heat’ even though the air temperature doesn’t reach the same levels as in a traditional sauna. There are many people who believe they get a better sweat and can even raise their body temperature more in an infrared sauna because of the more comfortable environment.

Are Infrared Saunas safe to use?

Infrared saunas are generally safe for most individuals. The lower temperatures and gentle heat make them suitable for people who may not tolerate the high temperatures of traditional saunas. Individuals with certain medical conditions or pregnant women should consult with their healthcare provider before using an infrared sauna.

What are the benefits of using an Infrared Sauna?

Infrared sauna health benefits include detoxification through sweating, muscle relaxation, stress reduction, improved circulation, pain relief, and potential skin purification. Infrared heat is believed to penetrate deeper into the body, promoting greater detoxification at the cellular level.

Can I install an Infrared Sauna in my home?

Yes, infrared saunas are designed for residential use and can be easily installed in various settings, including bedrooms, bathrooms, or spare rooms. They are available in various sizes and configurations to accommodate different space requirements and aesthetic preferences.

How does an Infrared Sauna differ from a Traditional Sauna?

Unlike traditional saunas, which heat the air to high temperatures which in turn heats your body, home infrared sauna uses far infrared to directly warm the body.This allows for a lower ambient temperature and a more comfortable sauna experience.

What do NIR (Near Infrared) and FIR (Far Infrared) mean, and are they safe?

Both NIR and FIR are types of electromagnetic radiation, similar to visible light, radio waves, and X-rays. They’re categorized by their wavelengths:NIR (Near Infrared): ~750-1400nm — Often used for therapeutic light applications.FIR (Far Infrared): 3000-50,000nm — Commonly used for heat-based wellness therapies.The term “radiation” can sound concerning, but it simply refers to energy traveling in waves.

It’s important to note:Shorter Wavelengths (e.g., X-rays, Gamma Rays): Higher energy, and prolonged exposure may pose health risks.Longer Wavelengths (e.g., Infrared, Visible Light): Lower energy, and typically considered safe when used as intended.Infrared radiation, when used in saunas, operates at wavelengths that are too long to have the same high-energy impact as X-rays or gamma rays.

Instead, these wavelengths are designed to provide effects like gentle heating (FIR) or light-based stimulation (NIR), which are associated with wellness benefits.

What temperatures do Infrared Saunas reach?

Infrared saunas operate differently than traditional saunas and are designed to be used at lower, more comfortable temperatures—typically between 110°F and 135°F. While most infrared saunas are programmed to reach up to 150°F, our models can be set higher. However, factors such as your home’s electrical setup and local power supply may affect the maximum temperature your Heavenly Heat Sauna can achieve.

Are infrared saunas energy-efficient?

Yes, infrared saunas are generally energy-efficient compared to other types of heating systems. They use infrared heaters with low energy consumption, making them a cost-effective option for home use.

What is the return policy?

You have 30 days from delivery to return your sauna if it’s not the right fit. Returns must be in “like new” condition and original packaging, and return shipping is the buyer’s responsibility. We also offer a manufacturers warranty on the structure and electrical components—so your investment is protected for the long haul.

View Refund Policy or Warranty Policy For Full Details

What is the warranty policy?

Heavenly Heat Saunas warrants that sauna cabins and factory-installed components, including heaters, control systems, power supplies, sensors, wiring, and related electrical components, will be free from manufacturing defects in materials and workmanship under normal residential use and proper installation.

  • Indoor Saunas: Covered for a period of ten (10) years from the original date of purchase.
  • Outdoor Saunas: Covered for a period of three (3) years from the original date of purchase. 

If a manufacturing defect is confirmed within the applicable warranty period, Heavenly Heat Saunas will, at its sole discretion, provide replacement parts, repair the affected wood component, or replace the part with a comparable model at the company’s discretion.
