🔧 Understanding UL 60335-2-53: What Changed?
On June 27, 2025, UL officially adopted UL 60335-2-53, aligning with the international IEC 60335-2-53 (Edition 4.2, March 2021) — with national deviations for the U.S. and Canada.
This new standard governs electric sauna heating appliances, and it’s a major step toward harmonizing North American safety regulations with European performance expectations.
The changes affect:
Temperature control limits
Safety testing methods
Installation guidelines
User interface and overheat protection

🇺🇸🇨🇦 Why This Matters for Sauna Buyers in the U.S. and Canada
Historically, North American electric sauna heaters were subject to stricter limitations than their European counterparts — often capping temperature outputs and requiring specific built-in safety systems.
With this new UL 60335-2-53 standard:
Manufacturers can now offer heaters closer to European performance
Consumers may soon see hotter, faster-heating models
Brands will need to update or recertify their products to stay compliant
It’s a big deal if you're investing in a high-performance sauna — whether for your home, wellness center, or luxury chalet.

🔍 Compliant Brands to Watch in 2025
As of now, each manufacturer must confirm their own compliance with the updated standard.
Here are leading brands to monitor:
HUUM
Harvia
IKI
Saunum
Narvi
Cozy
Finlandia

🧠 Should You Wait Before Buying Your Next Heater?

If you’re about to invest in a new electric sauna heater:
It’s wise to ensure it’s UL 60335-2-53 certified (or soon will be)
Ask your reseller (like us) for confirmation before you buy
Some heaters may temporarily go out of stock while being updated or re-tested
