What is special about the Heavenly Heat 4 Person Sauna?

Heavenly Heat Saunas are known for their ultra-low toxin materials, near-zero EMF output, and premium build quality. But their newest model the 4-Person Infrared Sauna with Integrated Red Light Therapy might be the most insane sauna on the market.

It’s not just big — it’s enormous, and it’s built for people who want the most advanced, most intense home-sauna experience possible. It's more of a wellness sacturary than a sauna. Keep reading to find out why.

What are infrared saunas?

An infrared sauna is a type of sauna that uses light, specifically infrared wavelengths, to heat your body directly rather than heating the air around you. Instead of relying on intense, ambient heat like a traditional sauna, infrared panels emit a gentle, penetrating warmth that raises your core temperature from the inside out.

This allows you to sweat more deeply at lower temperatures, making the experience more comfortable while still delivering powerful benefits like detoxification, improved circulation, muscle recovery, and relaxation.

Setup

The 4 Person is a beast and not easy to build. You will absolutely want to pay extra for the white-glove installation if possible.

If the white glove installation isn't a preferred option:

  • You will need two-three people to assemble but more will speed up the process.
  • It will take atleast a couple of hours to build.
  • The sauna requires 240V and a dedicated 30A circuit so professional installation by a licensed electrician is required.

Although on a dedicated circuit the founder told me that the sauna costs about $1 per session to operate, which is extremely reasonable for something this large and powerful.

Build Quality

Here’s where Heavenly Heat separates itself from 99% of the sauna industry:

✔ 100% pure Canadian hemlock wood

✔ No stains

✔ No glues

✔ No plywood

✔ Low VOCs and EMFs

This is a game changer as most sauna companies use adhesives, composite boards, or “non-toxic” coatings that still off-gas under heat. Heavenly Heat completely avoids that. Their units are independently tested for VOCs.

For anyone with mold sensitivity, chemical sensitivity, autoimmune issues, or on a detox protocol this is a massive deal. When you’re investing in a home sauna, especially for detox, mold recovery, or long-term health, the last thing you want is a unit that exposes you to more toxins or high EMFs.

This thing is a beast...

Dimensions:

  • Width: 7ft 4 inches

  • Depth: 4ft 8 inches

  • Height: 6ft 9 inches

Features

Because of its compact cubic volume, this sauna heats up fast. Inside the sauna, you’ll find a simple, intuitive control panel with the essentials:

Infrared Heating System

  • Adjustable temperature up to 185°F (rare)
  • Heats fast: reaches 120–130°F in about 20 minutes
  • Infrared panels positioned in front, below, side walls, and rear
  • 8mm tempered glass door (excellent heat retention)

Full-Body Red Light + Near Infrared Panel

This is the star of the show.

A massive panel runs down the center interior wall, providing:

  • Red light
  • Near infrared light
  • Added heat

You can choose red light only, near infrared only or both on a 30 minute built in timer.

Dual Control Panels

  • A control panel on the inside and outside of the sauna
  • Heater on/off button
  • Soft-touch interface
  • Adjustable session timer up to 60mins

Lighting Dual Control Panels

  • Light on/off
  • Color-changing LED settings
  • Choose between 9 different light settings. Glass cover (no plastic).

Audio

  • Built-in Bluetooth speakers mounted behind the ceiling

Ventilation

  • A manual adjustable vent on the ceiling for increased airflow

Low EMF Panels

Every infrared panel is positioned behind wooden slats, ensuring your body never sits directly against the heat source to improve comfort and reduce EMF exposure. Heavenly heat uses grounded low EMF/ELF heaters, faraday shielding, and no RF. EMF below 2 mg and ELF below 7 v/m.

Grounding Port:

An extra port is located by the floor of the sauna so you can use your favorite grounding products while inside.

Ease of Use

Before stepping inside, I grabbed my Trifield EMF meter to confirm whether the sauna lives up to its “lowest EMF on the market” claim. An EMF typical safe range is between 3-5mG and most readings landed around 0.3-1.0 mG. This is genuinely one of the lowest-EMF saunas I’ve ever tested. If you stand directly infront of the red light therapy device it will be higher but remains very low from a feet or so away. There will also be a hot spot near wiring, but this is common in all saunas. To get the EMF's so low the founder explained they use both grounded heaters and a faraday cage integrated into the roof, which are both expensive and difficult to engineer.

My Experience

I started my session and barley lasted 5 minuted before I was pooling with sweat. The combination of the red light therapy, red and near infrared light, massive heater converage and large heat volume meant it was one of the deepest, fastest detox sweats I’ve ever experienced. I was suprised it was so intense because of the size of the sauna but with the red light therapy it was super effecient.

The cabin itself is huge and can easily fit 5 or 6 people if needed and the benches are removeable for those who want to do hot yoga or a bike session.  For more info watch my full review video here.


Maintenance, Pricing and Warranty

Because the wood is light, you’ll want to lay a towels on the floor to prevent dirt stains, especially if you walk around barefoot like me. A towel also protects the wood from sweat, moisture buildup, and potential mold issues. Other than that, maintenance is minimal.

The 4 Person infrared sauna costs $22,200 at retail, so is definitely a very premium model. However you can get 6% off if you use code 'WELLNESSDADDY' at checkout.

Heavenly Heat provides an impressive 10-year warranty on the wood/carpentry and 6 years for electrical components including heater, which speaks volumes about the quality and durability of the materials. This is extremely rare in the sauna industry and shows the comoany expects this sauna to last a very long time.


Who Is It For (and Not For)?‍

✅ People sensitive to toxins, VOCs, chemicals, or EMFs
✅ Individuals detoxing from mold, heavy metals, or chronic illness
✅ Anyone who want the best premium, ultra-clean infrared sauna
✅ People who want a healing sancturary
✅ People who want a large social sauna
✅ Professional athletes and peak performers
✅ Executives or entrepreneurs with limited time
✅ People who enjoy hot yoga or in-sauna work outs

❌ Budget-conscious buyers as this is still a premium-priced model
❌ Those wanting a small more compact sauna such as the ECO or 2 person sauna
❌ Users who live in smaller apartments or renters
❌ Users who don't care about red light therapy

Final Thoughts

The Heavenly Heat 4 Person is the most powerful, most impressive, and most intense infrared sauna I’ve ever tested, and I don’t say that lightly. It delivers ultra low EMF's, zero toxins or adhesives, fast heat up times, a huge cabin, infrared, far infrared and red light therapy and a rare 10-year warranty. It genuinely has it all.

It’s not for everyone but if you have the means, the space, and the desire to create a true healing sanctuary, this is as good as it gets.

I can confidently say this is Wellness Daddy Certified, and would love to buy one for my own family one day. Use code WELLNESS DADDY to save 6% if you decide to purchase.
