You close the door and enter your own escape from the world for a while—an escape that gifts you with renewed energy and healing for your mind, body and spirit.

You can program the 24-hour timer to have your infrared sauna therapy experience ready whenever you’d like. Enjoy the silence, or create your ultimate relaxation playlist, or listen to the radio on your premium sound system.


The Signature III

Relax while immersed in quality. Sunlighten’s SoloCarbon® heaters deliver the highest quality and quantity far infrared heat available on the market, which means you get the most effective health benefits. Our technology design mitigates EMFs to a lower level than most common household items. The air is not suffocating or harsh, it’s a gentle, comforting warmth. The Signature III seats up to three people, with a comfortable, multi-function bench that can be removed to maximize room for stretching or simple yoga poses. Our powerful Magne-seal locking method makes assembly easy and keeps heat in with no unsightly screws or nails. Chromotherapy lighting enhances your home sauna experience using colors from the sun’s visible light spectrum to bring balance and mental wellbeing.

Be inspired!
