Sun Home Equinox™ Full-Spectrum Infrared Sauna Review

Trying to pick an infrared sauna from dozens of nearly identical-sounding listings can feel like a part-time job.

Every brand claims to be the fastest-heating, best-built, most advanced option out there.

I went through the full spec sheet and a wide range of verified customer reviews for the Sun Home Equinox 3-Person Full-Spectrum Infrared Sauna to help you separate the real details from the marketing copy.

This Sun Home Equinox 3-Person Full-Spectrum Infrared Sauna review covers what’s actually included, how it performs day to day, and who it’s likely to work best for.

Product Overview

The Equinox is a 3-person full-spectrum infrared sauna built from eco-certified, kiln-dried eucalyptus wood. Customer ratings on the brand’s site currently sit around 4.9 out of 5 stars.

It combines five FIR (far infrared) heaters with two 500-watt full-spectrum heaters, so it produces near, mid, and far infrared wavelengths rather than far infrared alone. According to Healthline, infrared saunas warm your body directly rather than heating the surrounding air, which lets them reach a deep sweat at a lower ambient temperature than a traditional steam sauna.

It runs on a standard 120V/20A dedicated circuit rather than requiring a 240V hookup, which some competing full-spectrum models need.

Key Features and Benefits of the Equinox Infrared Sauna

7 Heaters Across Full-Spectrum Wavelengths

The Equinox uses five FIR heaters plus two dedicated 500-watt full-spectrum heaters. Multiple reviewers reported it heating to the 120°F range in under 20 minutes and climbing into the 150s or 160s°F within 30 to 35 minutes, which is on the faster end for a home infrared sauna.

EMF Shielding

The heaters are built with EMF-shielding technology. If minimizing electromagnetic field exposure is important to you, this is worth noting, though it’s worth knowing that most quality infrared saunas on the market test in a similarly low range.

Built-In Bluetooth Surround Sound

A built-in Bluetooth speaker system lets you stream music or a podcast during your session. Several reviewers specifically praised the sound quality, though it’s worth flagging that the Equinox does not have WiFi connectivity or app control, only Bluetooth audio pairing, which surprised more than one buyer who expected remote app features.

Non-Toxic, Low-VOC Construction

The cabin is built with low-VOC, non-toxic materials. This could matter if you’re sensitive to strong chemical smells or off-gassing from new furniture and enclosed spaces.

Eco-Certified Eucalyptus Wood

Instead of the more common cedar or hemlock, the Equinox uses kiln-dried eucalyptus. Reviewers frequently mention the interior wood quality and finish as a standout, with more than one comparing it favorably to saunas they’d used at hotels or spas.

4-Hour Preheat Hold

Since there’s no app-based scheduling, the Equinox instead offers a 4-hour hold feature so you can start it ahead of time and have it ready when you want it. One reviewer called this feature a helpful workaround for the lack of remote app control.

Limited Lifetime Warranty

The sauna is backed by a limited lifetime warranty, and the brand states its heaters are rated for roughly 50,000 hours of use. That figure comes from the manufacturer, so treat it as a general durability claim rather than an independently verified number.

Weight and dimensions:

Interior dimensions: 56.8″ W x 39.9″ D x 70.3″ H
Exterior dimensions: 62.3″ W x 45.9″ D x 77.7″ H (includes 2″ feet)
Bench: 56.6″ x 20.2″, 19.5″ from the floor
Door opening: 28″
Overall weight: 620 lbs.
Electrical: 120V / 2,250W / 20A, dedicated circuit and outlet (NEMA 5-20r, 5-20p) — not compatible with a 240V outlet

If it’s going into an enclosed space, the manufacturer recommends leaving 4 to 6 inches of clearance around the unit and 8 to 10 inches above the roof for ventilation.

A Note on Health Benefit Claims

The brand’s own marketing lists a range of specific statistics on weight loss, disease risk, pain relief, and mood. Some of these trace back to real published research, though not always in the exact context the marketing implies, so it’s worth understanding the nuance.

For example, the often-cited link between frequent sauna use and lower dementia and Alzheimer’s risk comes from a Finnish cohort study on traditional high-heat sauna bathing, not specifically infrared sauna use. According to Mayo Clinic, infrared saunas can produce effects similar to moderate exercise, but larger, sauna-type-specific studies are still needed before drawing firm conclusions about disease prevention. I’d treat the more dramatic percentage claims (calorie burn, depression reduction, pain relief) as directional rather than guaranteed outcomes.

Pros and Cons of the Sun Home Equinox Sauna

Here’s a straightforward look at what stood out based on the specs and a wide range of customer feedback.

Things We Liked:

Reaches sauna temperatures faster than many competing infrared models, based on multiple reviewer reports
Runs on a standard 120V/20A circuit rather than requiring 240V
Reviewers consistently praise the interior wood quality and finish
Bluetooth sound system gets frequent, specific praise
Most buyers report assembly takes about one to two hours, sometimes with just one person
Backed by a limited lifetime warranty
Multiple reviewers highlighted strong, responsive customer service

Things We Didn’t Like:

No WiFi or app control, only Bluetooth audio — a letdown for buyers expecting remote preheat features
Several reviewers say the 3-person model comfortably fits 2 people rather than 3, especially if you like to lie down
A few buyers needed to have a new dedicated outlet wired in before they could use it

Verdict

The Equinox consistently earns praise for build quality, heating speed, and sound, with the most common complaint being the lack of WiFi app control despite its premium positioning. If remote scheduling isn’t a priority for you, that gap may not matter much in daily use.

Who Is This Sauna For?

This might be a good fit if you want full-spectrum infrared heat on a standard 120V circuit and don’t mind controlling the sauna manually rather than through a phone app.

It may not be the right choice if:

Remote app scheduling and control is a must-have for you
You regularly want three adults using the sauna at once rather than two
You’d rather avoid any chance of needing new electrical wiring installed

What Customers Are Saying

The Equinox holds a strong rating across a large number of reviews. Buyers consistently mention fast heat-up times, sound quality, and customer support, while the recurring criticism centers on the missing app connectivity and real-world seating comfortably fitting two rather than three.

“This company has the best customer service I’ve ever experienced… very easy to put together and works great! I use it every day.”
“We dropped the ball on the research and realized too late that the Equinox doesn’t play nice with the Sun Home app. No WiFi here, just Bluetooth for your tunes.”
“Assembly was remarkably easy — just two people and about two hours… we’re regularly getting close to 150°F in about 35 minutes.”
“We wanted a unit for two people comfortably, and this one is surprisingly spacious, airy, and never cramped.”
“Looking back I actually would have gotten the 5 person because my husband and I use it together almost daily and I love to lay out, but can’t do that in the 3 person when another person is in there.”
“I did have to wire in a new plug to be able to plug it in! But, so happy with this purchase!”
“The only problem we had is that this sauna is not wifi compatible so it does not work with the app.”

FAQ & Additional Tips

Where can I buy the Equinox sauna?
It’s sold directly through Sun Home Saunas, linked throughout this review.

Do I need an electrician?
It depends on your existing wiring. The Equinox needs a dedicated 120V/20A circuit, and some buyers needed a new outlet installed, while others were able to plug directly into an existing dedicated circuit.

How long does assembly take?
Most reviewers reported one to two hours, and several said it could be done solo, though having a second person made it easier given the weight of the panels.

Does it have an app?
No. The Equinox has Bluetooth audio only, with no WiFi or app-based remote control. It does include a 4-hour preheat hold feature as a manual alternative.

What’s covered under warranty?
The sauna comes with a limited lifetime warranty, and the manufacturer states the heaters are rated for approximately 50,000 hours of use.

How many people does it actually fit?
While it’s listed as a 3-person sauna, several reviewers say it’s most comfortable for two, particularly if one person wants to lie down during a session.

How should I use it safely?
Staying hydrated before and during your session is generally recommended. If you have a heart condition, are pregnant, or take medication that affects your body’s ability to regulate heat, check with your doctor before regular use.

Final Verdict

Based on the specs and the volume of buyer feedback, the Sun Home Equinox 3-Person Full-Spectrum Infrared Sauna looks like a well-built option if fast heat-up times, wood quality, and standard 120V compatibility matter most to you.

If app-based remote control is a deal-breaker, it’s worth checking whether a different Sun Home model or another full-spectrum brand offers WiFi connectivity before you commit to the Equinox specifically.
