Pairs well with
The glass corner
A sauna with an open corner of glass.
The lights are low under the benches and behind your back. Through the panoramic glass front the rest of the room is still there, softened by the heat. You lean back against the Tyrol wood and let the evening slow down.

The honest math
From $10 a session
Starting at $21,276, used 4 times a week for 10 years, works out to about $10 per session, before installation, electrical work and power. Your own rhythm sets the real number.
Why we carry it
Lumaria suits a home where the sauna should stay part of the room, not shut away behind a wall of wood. Two sizes and a choice of corner make it easier to fit. Confirm the door side, the electrical plan and delivery timing with us before you order.

Glass on the outside, warm wood on the inside.
Lumaria is a complete indoor sauna, not a heater sold without a room. A transparent glass front and corner entrance keep the room open to the space around it, while brushed Tyrol wood walls, thermally modified aspen benches, and lighting under the benches and behind the backrests set the mood inside.
