Harvia Virta
The Virta Sauna Heater blends performance, design, and tradition for a deeply restorative sauna experience. Its freestanding design delivers gentle, even heat—ideal for those who prioritize mental clarity and physical wellness. With a sleek black stainless-steel body and front-facing maintenance hatch, Virta is both functional and visually striking.
Built for durability, the heating elements are separated from the stones to reduce wear and extend the unit’s lifespan. Designed for frequent use, Virta supports the classic Finnish ritual of adding water to hot stones to introduce soothing humidity.
The Xenio Control Kit is required for operation and sold separately. Xenio features a sleek, wall-mounted touchscreen with an intuitive interface, providing staff with easy access to temperature control, scheduling, and sauna management—ideal for commercial wellness spaces.
Thermasol indoor saunas are delivered with pre-assembled panels and detailed installation instructions. Assembly typically requires two people, basic tools, and a few hours to complete. A licensed electrician must install the heater.
Indoor models are designed to sit directly on your existing flooring. The surface must be level and water-resistant. Suitable materials include concrete, ceramic tile, vinyl, or laminate. If your current flooring doesn’t meet these requirements, an alternative foundation may be needed.
All indoor sauna units are freestanding and can be disassembled and relocated if necessary.

Traditional (Finnish) Saunas: Typically operate between 150°F and 190°F (65--88°C), with a median standard between 165--180°F.
Infrared Saunas: Operate at lower, radiant heat temperatures, generally between 120°F and 150°F.
Beginners: Start with 10 to 15 minutes per session.
Advanced: You can stay longer (up to 20 minutes), but it is best done in "innings". Do a 15-minute session, exit to cool down and rehydrate for 5 minutes, and then return for another round. Always listen to your body and exit immediately if you feel dizzy or nauseous.
This is a matter of personal preference. Traditional saunas use heated rocks where you can add water to create steam and instantly increase the humidity. Infrared saunas are run dry without rocks or steam. You can also add essential oils to your water for aromatherapy.
Before: Yes, shower beforehand to rinse off perfumes, lotions, and oils to keep the sauna sanitary and help your skin sweat freely.
After: Yes, rinse off the sweat, salts, and toxins, and help your pores close back up.
Regular sauna use supports:
Traditional Saunas: Heat the air in the room to high temperatures using electric or wood-burning heaters.
Infrared Saunas: Use invisible light spectrum wavelengths to heat your body directly rather than superheating the surrounding air.
Sauna therapy is generally safe, but you should consult a doctor first if you have underlying cardiovascular conditions, take certain medications, or are pregnant. Never use a sauna if you have a fever, are under the influence of alcohol, or feel lightheaded.
