Can I use the red light without the heat?
Yes. The red light panel runs on its own, with the heaters on or off. Protective glasses come with your sauna.
See the red light panelDoes it plug into a regular outlet?
Yes. Rainier plugs into a standard household outlet. You do not need an electrician.
120V / 15A / 1,800W — plugs into a standard outlet (NEMA 5-15P)
A 9-foot power cord is included. Check the owner’s manual for the outlet and circuit requirements.
View owner’s manualHow is Rainier different from Shasta?
Only the wood is different. Rainier is Canadian Red Cedar, and Shasta is hemlock. Size, heaters, red light and power are the same.
Cedar has a warm, natural aroma. Hemlock is lighter in color, with a mild scent.
Can it go in my garage or on a covered patio?
A garage or basement works well. Set Rainier on a level, solid floor. A cold room adds heat-up time.
Do not put an indoor model outside, even on a covered patio or porch. If the spot is open to rain, snow, sun or outdoor air, it is not suitable. For outdoor spaces, choose an outdoor model.
See the Outdoor SeriesWill it fit my space?
Rainier measures 42″W × 40″D × 75″H on the outside. Measure your location and the route to it before ordering.
Leave 1–2 inches of space at the back and on both sides. In front, leave room for the door to open.
Cabin dimensions are not installation clearances. Check door swing, access and service space in the manual before you choose a location.
Check dimensions and fitHow hot does it get?
Near, mid, and far infrared heat, up to 150°F.
You feel warmth in about 15–20 minutes. Full temperature takes about 45–60 minutes, and longer in a cold room.
Start the heat from the Smart Life app before you get there, so your sauna is ready when you are.
When will it arrive, and who sets it up?
Curbside delivery is included in the contiguous U.S. Your sauna travels in a reinforced PeakGuard crate, with protective padding between the panels.
Check the current availability and delivery estimate beside the purchase controls. Contact PEAK to confirm timing for your address.
