A note from Taylor, Designer & Co-Founder
Most wellness products ask you to make room for them. I wanted to design one that became part of the room.
ARC is our vision for the first invisible sauna, a functional piece of furniture that reflects the space around it and hides what’s inside until you’re ready to use it.
Wellness shouldn’t compete with great design. It should disappear into it.
Chief Creative Officer & Co-Founder of LIT INC.
Your sauna is already home.

How hot does the Arc get, and how long does it take to heat up?

What's the difference between the Arc's infrared heat and its red light?
