Finnish Quality

The Harvia Club combines exceptional modern craftsmanship with the age-old tradition of Finnish sauna bathing to deliver a sauna heater without peer. The Club has a large rock capacity that directly contacts the heating elements to ensure a consistent and even flow.

Made in Finland of durable, corrosion-resistant stainless-steel components, the Harvia Club is designed for years of safe and reliable operation.

Commercial Capabilities

The Club is almost completely made out of stainless steel, meaning this heater is made to run almost all day for tons of people.

In commercial mode, the heater can be set to run 18 hours every day, which proves that this heater is really made to be used all the time. The Club is also made for home use with 240V/1PH to bring reliability to households rather than just commercial spaces.

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.
