Key Features

Top-Notch Quality

Rounded Design

External Control Unit

Top-Notch Quality

The high-quality Harvia Spirit is made and designed in Finland. The Spirit is Harvia’s example of high-quality craftsmanship combined with safety and reliability.

The Spirit meets regulations and local requirements for electric sauna heaters in the USA. The Spirit has an integrated safety function that ensures that the heater cannot be turned on if any items are placed on top of it. Also, there are two safety sensors; one monitors the heater and the other monitors the sauna's temperature to prevent overheating.

Rounded Design

The curved body egg-like design is made to be used with rounded stones tying the Spirit and the stones together. The rounded stones provide a soft steam, making the heater not only look great but also perform well.

All Harvia heaters go up to 195F and this heater is no exception.

Wall-Mounted

The construction of the Spirit protects the wall of the sauna and creates an even temperature because of its unnoticeable ventilation ducts. The integrated ventilation ducts prevent the walls of the sauna from getting too hot and enhance the air circulation through the heating elements creating an even temperature. .

External Control Unit

The heater is controlled by an external controller. With its sleek and elegant touchscreen design, the sauna heater controls may be surface or flush-mounted and adjust for time duration, temperature, and room lighting. There is also a Wi-Fi option for turning the heater on remotely.

Highly Recommend This Company

The team at Soaknsweat was absolutely incredible. I honestly didn’t think customer service like this still existed. Kris and the crew actually answered the phone, patiently walked me through every question, and helped me make several key decisions for my sauna setup. They followed up quickly, were extremely professional, and truly earned my business and recommendation. Their YouTube content was also a huge help during the planning phase — and one of the main reasons I chose to order from them. Thanks, team!

Building Phase

I’m currently in the process of designing and building a sauna. After a lot of online research and frustration, I discovered Soak 'n Sweat — and it was a game changer. Their educational page covers every aspect of sauna design and answered nearly all my questions through detailed articles and videos. When I reached out via chat, Kris patiently addressed the rest of my questions without any pushy sales tactics. These folks really know their stuff, provide great products, and make the whole experience smooth and informative. Thank you!

Kris even went above and beyond by giving me a call, making it easy to get answers right away — and it was after business hours! Their knowledge, patience, and genuine willingness to help made the entire experience smooth and stress-free. I’m extremely impressed with their customer service and highly recommend Soak 'n Sweat to anyone looking for quality products and exceptional support.
