Frequently asked questions
What room size does 9 kW suit?
Around 400 to 500 cubic feet as a guide. The manufacturer's rated room size is on every product page and is the number to trust.
What electrical supply does 9 kW 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.
Built-in or external controls?
Both are available at this rating. The product page says which, and lists compatible control units where one is needed.
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.
