🔧 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

Here are leading brands to monitor:


HUUM


Harvia


IKI


Saunum


Narvi

🧠 Should You Wait Before Buying Your Next 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
