What is recorded, and what is not

Sauna Critic is a reference table for 45 home saunas from 24 brands across 6 categories, from $125 sweat blankets to $26,890 cedar rooms. It is an unusually hard category to research, because a large part of it is sold on wellness language that no specification backs, and the figures that decide whether you will use the thing twice a week — heater output, wall thickness, the temperature it genuinely reaches — are often not published at all. This page is mostly about what happens when they are not.

The blank cells are the point

15 of the 45 units here state a heater rating in kilowatts, and 10 state a maximum temperature. The rest, 35 show nothing in that column. That is not an oversight waiting to be filled: for a cabin kit the honest answer depends on your room, your insulation and your climate, and any single number would be a guess wearing a decimal point. A sauna that reaches 190°F in a heated basement will not do it in an unheated garage, and a manufacturer that declines to promise a figure is being more careful than one who prints one. Filling those cells would make the table look complete and make it worth less.

Claimed low-EMF and measured low-EMF are different statements

Nearly every infrared brand prints “low EMF” somewhere. Of the 15 units here with emitters, 13 make that claim with nothing published behind it and 2 point at a third-party measurement. The catalog stores those as two different values and says which is which on the page, and reads “not applicable” on anything without infrared emitters, where the phrase means nothing. There is no gaussmeter here and nothing has been measured by us — the distinction being recorded is between a brand's assertion and a brand's evidence.

Where the specifications come from

Heater output, dimensions, wood species, seating capacity, warranty terms and installation requirements are taken from manufacturer documentation and dealer listings. The figures here are ordinary list prices in US dollars. Two things move them: this category discounts constantly, and freight is quoted separately and can be several hundred dollars on anything that arrives on a pallet — so a price here places a unit in a tier rather than quoting what lands on your card. The electrical requirement matters as much as the price on the traditional side, where a 6kW heater usually means a dedicated 240V circuit.

Why there are no star scores

Sauna reviews are thin next to mass-market products and scattered across dealer sites, and no source could be cited model by model. A score built on that few voices says less than a published heater rating does, so the pages show the specifications and the owner reports and leave scores out.

Where the owner reports come from

There is no sauna at this address, no test room, and no hands-on session to report. The pros and cons on each page are gathered from what owners post in the open — people some winters into owning one, brand communities, long-term write-ups, and dealer question-and-answer threads — and are presented as what owners said rather than as findings. A complaint earns a line when unconnected owners keep raising it: a barrel that bleeds heat below freezing, a small cabin that tops out cooler than the listing suggested, freight arriving with a cracked glass panel and a long argument about who pays. Which of those recur often enough to print is a call made here.

Two people, and no arrangement with any brand

Two people maintain this, and neither of them sells saunas. No office, no showroom, nobody on a payroll. No manufacturer or dealer pays for a listing or a position, none has ever been shown a page before publication, and category and brand pages list the cheapest unit first, so placement follows from the price.

When the table changes

Read through on August 8, 2026. Saunas move slowly compared with most consumer categories — a cedar cabin sold in 2021 is often still sold today — so most changes here are added models, corrected prices, and the occasional brand that stops shipping to the US. A figure that disagrees with the manufacturer's documentation is an error in this data rather than an advertisement.
