9 to 12 kW Sauna Heaters

9 to 12 kW covers the larger home room: five or six people, a high ceiling, or a lot of glass. It is also the band to choose when an outdoor sauna has to come up from a cold start through a Bay Area winter.

Frequently asked questions

When do I need this much output?

When the room's volume calls for it: high ceilings, large glass panels and outdoor installations all push you up a band from what the floor area alone would suggest.

What electrical supply does it need?

Traditional heaters above about 4.5 kW generally need a dedicated 240V circuit sized by a licensed electrician. Infrared cabins are the exception and often run on a standard 120V outlet. The requirement is listed on every product page: confirm it before delivery, not after.

Will it overheat a small room?

An oversized heater cycles more and can make the room harsh. Match the rating to the volume rather than buying the largest that fits.

How do I pay?

Card or bank transfer (ACH), both at checkout. Stripe handles the payment, so your card details never reach us. A transfer takes a day or two longer to clear, and on a large order it is the one we prefer.

Can you install it?

In the Bay Area, yes. Your Saunas is a licensed general contractor, CSLB #1150020, so the carpentry and the electrical are the same crew rather than two trades blaming each other. Further afield we ship and you bring your own installer. Call (707) 625-5555 before you order if you want the install quoted with the sauna.
