Feel confident when you choose Sunlighten.


Craftsmanship and safety standards set Sunlighten apart. We are the only manufacturer with ETL certification. ETL-certified components are installed, including wiring and electronics. A third-party company has tested our VOC levels to find only trace levels with no airborne metals, sulfur dioxide, or carbon black.

Our saunas are made with 100% premium wood throughout the entire cabin – no hidden plywood. All wood is ¾” tongue-and-groove for greater strength and durability. Extensive third-party testing has been conducted to ensure all our materials are safe and non-toxic.


Imagine the possibilities.

Sunlighten is amazing! Really appreciate all of the help and extra coordination from Tracy to help build our custom saunas. The process has been so smooth, the product is stellar, the samples are fantastic, and customer service is unparalleled. No other sauna company has even come close in any regard. Thanks for making this so easy - I plan on using Sunlighten for every project moving forward.
