Heatwave 2-Person Infrared Sauna Reviews: Honest Pros & Cons

What Should You Expect?

Buying an indoor sauna is not a small decision. You need to know whether the cabin will fit your room, whether two people can use it comfortably, and whether the advertised features justify the space and cost.

You may also be wondering if infrared heat offers anything different from a traditional sauna. The answer depends on what you want: faster warm-up, a lower operating temperature, quiet relaxation, or simply a private place to sit after a long day.

For this Heatwave 2-Person Infrared Sauna Review, I examined the listed specifications, warranty information, owner’s documents, and customer feedback. I’ll focus on practical details and keep health claims measured rather than treating the sauna as medical treatment.

Product Overview

The Heatwave 2-Person Hemlock Premium Infrared Sauna is an indoor FAR infrared sauna with six carbon heaters, Canadian Hemlock construction, chromotherapy lighting, ventilation, and an integrated stereo system.

Wayfair lists the model at 4.7 out of 5 stars from 33 reviews. The customer feedback is generally positive about heat-up time and assembly, but some buyers question the actual width, seat depth, and two-person comfort.

The cabin reaches a listed maximum temperature of 140°F and uses 1,725 watts at 120 volts. It includes one bench, a tempered glass door, interior and exterior control pads, and a seven-year limited product warranty with different coverage periods for different components.

Features That Affect Daily Use

Six FAR Carbon Heaters

The six carbon heaters are positioned to provide heat around the cabin rather than from one source alone. The listing says they produce wavelengths between 5 and 12 microns and use 1,725 watts in total.

For you, the practical benefit is steady radiant heat without needing the cabin to reach the much higher temperatures associated with many traditional saunas. Some owners reported reaching 140°F in about 20 minutes.

However, heating time depends on room temperature, ventilation, and how long the sauna has been running. One reviewer using the sauna in a cooler garage may experience a different warm-up time than someone using it in a heated room.

Research does suggest that sauna bathing can produce cardiovascular and circulatory responses, but it does not prove that every advertised infrared benefit applies to every user. A systematic review on infrared sauna exposure and heart failure found some short-term improvements, while also noting that the evidence ranged from moderate to insufficient and that more long-term research is needed.

Canadian Hemlock Construction

The cabin is made from solid Canadian Hemlock with tongue-and-groove joinery and a quick-clasp buckle assembly system. Hemlock has a relatively mild scent compared with aromatic cedar, so it may be more comfortable for people who dislike strong wood odors.

The product is also described as rot-resistant, antimicrobial, water-resistant, and mold or mildew resistant. Those are product-level claims, not a guarantee that the sauna can be placed in a damp outdoor environment; Wayfair identifies it for indoor use only.

The wood finish gives the unit a furniture-like appearance. If you want a sauna that blends into a home gym or bedroom, that may be more appealing than a utilitarian metal or plastic design.

Dual-Wall Insulation

Dual-wall cabinetry is designed to retain heat inside the cabin while keeping the exterior cooler than the heated interior. The manufacturer also says the design offers more interior space than some price-focused competitors.

One customer, however, reported a seat that felt too shallow when used with the backrest. Another said the two-person model was not quite large enough for two adults and wished they had ordered a three-person version.

That feedback is important because “two-person” usually describes maximum capacity, not generous personal space. If you and another adult plan to use the sauna together often, measure the interior before deciding.

Chromotherapy and Reading Lights

The Heatwave includes an eight-color chromotherapy system, recessed interior reading lights, and exterior accent lighting. These features may improve the atmosphere of a session, especially if you want dim lighting and quiet relaxation.

The listing calls the colored lighting a health and healing feature, but the evidence for broad medical benefits from sauna chromotherapy is not established by the product information. I would treat it as ambient lighting rather than a treatment.

Ventilation and Oxygen Ionizer

The cabin includes a ceiling vent, floor vent, and electronic oxygen ionizer. Adjustable vents may help manage airflow and prevent the interior from feeling stale during longer sessions.

The ionizer is marketed as a way to purify air and reduce odor-causing bacteria. Those claims should not be confused with air sterilization, and the listing does not provide independent performance testing for the ionizer.

Built-In Stereo System

The audio system supports FM radio, CDs, and an MP3 auxiliary connection. This is useful if you prefer podcasts, music, or guided relaxation while you sit.

One owner connected the stereo to an Alexa Echo Dot and reported that it worked well. Another reviewer said the stereo function was reliable, while the lack of advanced wireless controls may feel dated compared with newer Bluetooth-first systems.

Tempered Glass Door and Interior Controls

The bronze-tinted tempered glass door offers visibility while helping the cabin feel less enclosed. Interior and exterior LED control pads let you adjust settings without opening the door.

A tempered glass door is still heavy and vulnerable to shipping damage. Inspect the door, hinges, handle, and glass before completing assembly, especially because one customer received a sauna with a damaged hinge and had to wait for replacement parts.

Weight and dimensions:

Interior dimensions: 5′ 7″ high x 3′ 7″ wide x 2′ 11″ deep.
Overall dimensions: 6′ 3″ high x 3′ 11 1/4″ wide x 3′ 3 1/4″ deep.
Overall product weight: 354 pounds.
Seating capacity: Two people.
Number of benches: One.
Power requirement: 1,725 watts, 15 amps, 120 volts.
Assembly: Required; two people are recommended.
Installation location: Indoor use only.

Check the maximum width carefully. One reviewer said the top was closer to 49 inches wide than the listed 47.25-inch measurement, which required modifying an existing 48-inch closet opening. The overall dimensions supplied by Wayfair list the width as 3 feet 11 1/4 inches, so leave extra clearance rather than planning for a very tight fit.

Pros and Cons

The Heatwave offers more built-in features than a basic infrared cabin, but some comfort and quality-control issues may matter if you plan to use it with another adult frequently.

Things We Liked:

Six carbon FAR infrared heaters are spread throughout the cabin.
Most owners reported reaching operating temperature in around 20 minutes.
Solid Hemlock construction gives the cabin a neutral appearance and mild scent.
Chromotherapy, reading lights, and exterior accent lighting are included.
FM, CD, MP3 auxiliary, and stereo functions provide several audio options.
Interior and exterior controls make temperature and lighting adjustments convenient.
Seven-year limited warranty provides longer overall coverage than the one-year radio warranty.
UL Listed and cETL Listed safety certifications are stated in the product details.

Things We Didn’t Like:

The bench may feel shallow, especially when using the included backrest.
Two average-size adults may fit closely rather than comfortably.
One customer reported that the actual top width exceeded the listed measurement.
A damaged hinge, an unlevel base, and loose support boards were reported by one buyer.

Verdict

This sauna could be a reasonable option if you want a feature-rich indoor cabin with quick warm-up and built-in audio. I would not choose it without measuring the installation area carefully, and I would consider the three-person version if two adults will use it regularly.

Who Is This Product For?

The Heatwave might suit someone who wants an indoor sauna for relaxation, post-workout heat, or a regular home wellness routine and has enough clearance for its large, heavy cabinet. It may also appeal to you if lighting and audio are important, since those features come built in rather than requiring separate accessories.

Homeowners with a dedicated indoor room, basement, or home gym area.
Users who want a 140°F FAR infrared sauna rather than a hotter traditional steam sauna.
People who value chromotherapy, reading lights, ventilation, and stereo features.
Couples who are comfortable sitting close together during a session.
Less suitable for very tight closets, taller users, or anyone who wants generous two-person seating.

What Customers Say

The 33 Wayfair reviews are mostly favorable. Customers commonly mention good packaging, simple assembly, a 20-minute warm-up, attractive construction, and reliable stereo and lighting features.

The negative feedback is more practical than fundamental. Buyers reported a shallow bench, limited room for two people, a width discrepancy, loose base supports, and shipping damage to a door hinge.

One owner said the sauna arrived well packaged, reached 140°F in about 20 minutes, and worked well with an Alexa Echo Dot. They used it almost every night but warned that the actual top width was larger than expected.
Another reviewer praised the solid construction, quick heating, easy assembly, and chromotherapy lighting.
A customer said the sauna operated well but found the bench too shallow. With the backrest installed, they felt as if they were sitting near the edge.
One buyer regretted not ordering the three-person model because the two-person cabin did not feel large enough for two adults.
A reviewer reported that the base supports came loose, leaving the floor uneven, and that the sauna rocked when entering. They also received a damaged upper door hinge and were waiting for replacement parts.
Another customer said delivery was on time, setup took about two hours alone, and the unit heated in approximately 20 minutes. They strongly recommended having two people for assembly.
One owner described the sauna as easy to use and well built, but said the backrest caused an uncomfortable seating position and they preferred sitting against the heater panel instead.

FAQ and Additional Tips

How long does it take to heat?
Several owners reported reaching 140°F in about 20 minutes. Actual performance can vary with room temperature, starting temperature, ventilation, and how long the door remains open.

Does it require special wiring?
The specifications list 1,725 watts, 15 amps, and 120 volts. That indicates a standard household-voltage design, but you should confirm that your circuit can safely support the load without other high-draw appliances running on the same circuit.

Can two people use it comfortably?
Two people can fit according to the listed seating capacity, but customer comfort reports are mixed. Several owners said the cabin works better for one person or that two adults sit very close together, and one specifically recommended sizing up.

What is the warranty?
Wayfair lists a seven-year limited product warranty, with five years for heating and electronics and one year for the radio. Parts-only coverage, inspection requirements, normal-wear exclusions, and care-related exclusions apply, so read the warranty document before purchasing.

Where can I buy it and what does it cost?
The product is listed on Wayfair. The current price may change with sales, promotions, and delivery charges, so check the live product page rather than relying on a fixed price in an evergreen review.

How should I use it safely?
Start with a short session at a moderate setting, especially if you are new to sauna use. Drink fluids, avoid alcohol, stand up slowly, and leave immediately if you feel dizzy, nauseated, weak, confused, or experience chest discomfort.

The available medical guidance on sauna precautions recommends extra caution for people with cardiovascular disease, low blood pressure, kidney disease, pregnancy, or conditions and medications that affect hydration or heat tolerance. Ask your clinician before use if any of those apply to you.

What should I do when it arrives?
Inspect the boxes, glass, hinges, heater panels, base, and wood edges before assembly. Photograph damage immediately and contact the seller before using the sauna or attempting a repair.

Final Verdict

My conclusion from this Heatwave 2-Person Infrared Sauna Review is that the model could work well for a home user who wants six carbon heaters, quick warm-up, Hemlock construction, chromotherapy, and several audio options. The main cautions are the close two-person fit, shallow bench, heavy 354-pound cabinet, and reports of measurement and quality-control issues.

If you have enough clearance and expect to use it mostly alone or with one person sitting closely beside you, it might be worth comparing the current Wayfair price and warranty terms. If two-person comfort is your priority, I would look at a larger model before committing.
