Whether you're shopping for a traditional sauna or infrared model, one question comes up a lot: What’s the difference between a premium sauna and a cheap one?
At first glance, many saunas look similar—wood walls, a glass door, maybe a digital control panel. But under the surface, there are major differences in build quality, heater safety, EMF exposure, lifespan, and overall performance.
Here’s how to spot the differences that matter before you buy.
1. Wood Quality & Construction
Cheap saunas often use soft, untreated or poorly dried wood. This can warp, splinter, or even release toxins when exposed to high heat. Premium saunas from brands like Auroom, Finnmark Designs, or SaunaLife use kiln-dried, knot-free wood like Thermo-Aspen, Canadian Hemlock, or Western Red Cedar—designed to handle decades of heat and moisture.
-
Cheap sauna: Warping wood, weak joinery, thin walls
-
Quality sauna: Precision-milled panels, thick insulation, tight tolerances
2. Heater Performance & Safety
The heater is the engine of your sauna. Inexpensive units often come with low-quality heaters that don’t heat evenly, take longer to reach temp, or pose overheating risks. Premium heaters from Harvia, HUUM, and Saunum offer faster warm-up times, smarter steam distribution, and precise digital controls—often with WiFi app functionality.
-
Cheap heater: Low stone capacity, uneven heat, basic analog controls
-
Quality heater: WiFi/app controls, large stone beds, premium materials

3. Safety: EMF, Glass, and Wiring
In infrared saunas, EMF levels are a critical health consideration. Brands like Finnmark use medical-grade low-EMF carbon panels with certified testing. Lower-end infrared units often exaggerate their EMF claims or skip third-party verification entirely.
For traditional saunas, poor electrical installation, unshielded cables, or thin glass doors can also lead to unsafe conditions in high heat environments.
-
Cheap sauna: Unverified EMF ratings, thin tempered glass, generic wiring
-
Quality sauna: Independently tested EMF, 8mm glass, ETL/UL listed wiring
4. Warranty & Service Support
Low-cost sauna manufacturers often provide minimal support and limited warranties. Reaching customer service can be frustrating—and replacement parts may not be stocked in the U.S.
Premium saunas often come with 5 to 10-year warranties, full parts support, and accessible U.S.-based service teams.
-
Cheap sauna: 1-year warranty, limited U.S. support
-
Quality sauna: 5–10 year warranty, dealer-backed customer service
5. Installation & Design Experience
Cheaper saunas often arrive with vague instructions and poor labeling, leading to confusion or damage during assembly. Premium kits are easier to install, with clear diagrams, labeled parts, and better packaging. Some even offer virtual support or full installation add-ons.

Is a Quality Sauna Worth the Price?
Yes—if you plan to use your sauna regularly, value comfort and durability, and want peace of mind that it’s safe, reliable, and backed by a real company.
Quality saunas will last 10–20+ years with proper care. Cheaper models often fail within a few years, especially in humid or outdoor environments.
