We know your dream sauna or cold plunge kit is a big purchase. That’s why we partnered with Affirm to finance your purchase with interest rates as low as 0% APR.
Rates from 0–36% APR. For example, a $6500 purchase might cost $271/mo over 24 months at 0% APR. Payment options through Affirm are subject to an eligibility check and are provided by these lending partners: affirm.com/lenders. Options depend on your purchase amount, and a down payment may be required. See affirm.com/licenses for important info on state licenses and notifications.

Please double-check your shipping address at checkout—any errors may result in re-routing fees.
Once your order ships, you'll receive two tracking links to monitor its journey: one for transit to the local depot and another for final curbside delivery.
All freight orders include an “appointment required” service. Carriers will typically call ahead to schedule delivery, though some may call when already en route. If you’re unavailable at that time, you may reschedule—just note that missed deliveries without prior arrangement can result in extra fees.
Delivery timelines are estimates and may be affected by weather, carrier delays, or other unforeseen events. Shipping rates may vary over time, but you’ll always see the full cost before placing your order.
Any adult at the delivery address is considered authorized to accept the shipment.
Are there any special requirements for the Harvia Wi-Fi heater installation?
Harvia Wi-Fi sauna heaters require 240v and must be hardwired to your electrical panel.
Your heater package will include a Xenio Wi-Fi Remote Kit which is required for installation and contains the following:
Power Unit
Control Panel w/ 16’ Cable
Temperature Sensor w/ 13’ Cable
Installation & Waterproofing:
The Control Panel, Temperature Sensor, and heater will all connect into the Power Unit (see diagram below).
❗Note: The Power Unit and Control Panel are not weatherproof and must be housed in weatherproof protection or installed in a dry area. Do not install the Power Unit or Control Panel inside the sauna.
The cables provided for the Control Panel (16’) and Temperature Sensor (13’) must not be spliced, so it is important to plan where these will be installed in accordance with those lengths. If a longer cable is needed, it may be specially ordered in lengths up to 82' for an additional cost.
Wi-Fi Signal:
The Control Panel must be located where it has a strong Wi-Fi signal to allow for remote control from your smartphone or tablet.
Can I upgrade to the Wi-Fi control at a later date?
Harvia heaters with manual controls cannot be upgraded to Wi-Fi. Switching to Wi-Fi control requires replacing the heater.
Homecraft heaters with manual controls can be upgraded to Wi-Fi control later with a compatible Wi-Fi control system.
