Sun Home Saunas Review: The Best Testing in the Category, and You Cannot See It

Sun Home paid two independent labs to test their saunas, and then put the results on a page almost nobody reads.

We checked all 24 of their product pages. Not one shows the EMF figure. Not one shows a wavelength. Not one names the lab. The testing exists, it is better than anything in our own catalogue, and it lives in an FAQ block on a category page called Best Infrared Saunas. If you are standing on the Solstice product page with a credit card out, you will never see it.

We do not sell Sun Home. We sell 26 full spectrum cabins from other manufacturers. This review is about what they publish, where they publish it, and how it compares to what our own suppliers manage.

What the testing actually says

On that one collection page, Sun Home publishes two results:

• EMF: 0.5 mG at seated position, tested by Vitatech Electromagnetics, January 2025.
• VOC: 27 µg/m³ total volatile organic compounds, tested by VERT Environmental, an AIHA-accredited lab, April 2026.

Read that again with the distances in mind. A named lab, a named measurement position, and a date, on both tests. The red light panels in their Eclipse and Pod models are published at 660 and 850 nm.

Nothing in our catalogue is documented to that standard, and we are not going to pretend otherwise. We researched EMF disclosure across 39 manufacturer spec sheets covering the cabins we sell. Nine of them state two different measurement distances for the same sauna, in two rows of the same table. Some tiers are measured at 2 to 3 inches from the panel and some at 6 to 8, which are not comparable numbers, because the field falls off sharply as you move away. And across the 24 red light equipped units we stock, not one publishes a wavelength at all.

So on documentation, Sun Home wins, and it is not close.

Why the placement matters anyway

A specification a buyer cannot find during the decision is not doing the work it was paid for. Sun Home's own positioning says they publish their independent lab testing, and they do. What they have not done is put it where the purchase happens.

If you are considering one, here is the practical instruction. Open their Best Infrared Saunas collection page and read the FAQ block at the bottom before you open any product page. Then ask their sales team, in writing, whether the tested unit is the model you are buying. One test result on a category page does not tell you which cabins in the range it covers, and we could not determine that from the outside.

The three lifetime warranties

Three sauna companies in this article use the same two words, and they are three different promises.

• Sun Home is a manufacturer. They design and sell only their own products, so their lifetime warranty is a company standing behind a thing it built. That is the strongest version of the promise.
• Almost Heaven is owned by Harvia. Their Limited Lifetime Warranty covers the sauna room, and the Harvia heater inside it carries one year on the heating elements and five on the other heating components. Lifetime on the room, one year on the coils.
• We are a retailer. We sell 673 products from more than thirty manufacturers, and a retailer cannot warrant something it did not build. What you get from us is the manufacturer's term, and our job is to tell you what that term actually is before you pay rather than after something fails.

Saying that plainly costs us the comparison and it is the truth. Here is what those terms look like across the heater brands we sell: HUUM offers five years limited with the heating elements excluded outright. Narvi covers the stove for two years and the resistors for twelve months. Harvia covers heaters for two years, plus a year if you register. In every case the part most likely to fail carries the shortest term or none at all.

There is a fourth position we did not have when this was written. Clearlight also manufactures its own cabins, at lifetime residential and five years commercial, and their review covers the thing they do better than anyone and hide better than anyone. Sunlighten is the fifth position and the shortest: seven years, printed on the product page.

One thing we could not resolve

Sun Home's own wording is a limited lifetime warranty on most models. We could not determine from their published pages which models are excluded or why. We are flagging the wording rather than characterising it, because an unenumerated exclusion inside a lifetime warranty is the same shape as the element exclusions above, and those turned out to be real and specific once somebody read the documents. Ask them which models, and ask for the answer in writing.

Price

Sun Home sells 11 infrared saunas from $4,999 to $13,899, median $6,999. Our full spectrum range is 26 cabins from $2,699 to $9,999, median $4,847. Both figures are entry prices, the cheapest way into each unit, so they compare like for like.

That is roughly $2,150 less at the middle of the range and $2,300 less at the entry point. Their cold plunges run $3,799 to $15,199 against our 18 cold plunge tubs from $760 to $14,995.

We have put the price section here rather than at the top on purpose. If you are choosing on documentation, they are better and the money should not change your mind. If you are choosing on price, we are cheaper and you should know what you are giving up.

Who should buy Sun Home

Someone who wants published, third party, dated test results and is willing to pay a premium for them. That is a legitimate reason to spend more, and it is rarer in this category than it should be. They are a five year old company selling their own designs, which is a different risk profile from a thirty year old brand selling through dealers, and whether that reads as agility or as youth is your call rather than ours.

Someone comparing on specification should do the thing this whole article is about. Ask every seller for the mG figure, the distance it was measured at, the lab that measured it, and the date. Sun Home can answer all four. Most of the industry, ours included, can answer one or two. That question separates a company that tested its product from one that wrote a number on a page, and it costs you nothing to ask it.
