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.

Space Requirements

Thermasol outdoor saunas are delivered fully assembled. A forklift or crane is required for placement, and a licensed electrician must install the heater.

The path from delivery point to placement site must be clear and accessible for equipment. Saunas should be installed on a firm, level surface with slight runoff for drainage—such as concrete, decking, pavers, or compacted gravel.

The Top Sauna Questions Answered for You

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:

  • Heart Health & Circulation: Improved vascular function and lower blood pressure.
  • Muscle Recovery: Loosens stiff joints and eases muscle soreness.
  • Detoxification: Flushes heavy metals (like lead, cadmium, and mercury) through heavy sweating.
  • Relaxation & Sleep: Helps lower cortisol and promotes deeper, restorative sleep.
  • Private Saunas: Go completely bare or wrap yourself in a cotton towel.
  • Public/Gym Saunas: Swimsuits or towels are typically required by facility rules.
  • Pro Tip: Avoid wearing metal jewelry as it can heat up and burn your skin, and leave electronics (phones, earbuds) outside—extreme heat damages batteries.
  • Saunas cause significant fluid loss through sweating, resulting in temporary reductions in "water weight". However, it is not a replacement for regular exercise and a proper diet for burning fat.

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.

  • Proper ventilation is critical so you don't sit in a "suffocation box" with depleted oxygen and high CO₂ buildup. A well-designed traditional sauna has an intake vent near the floor by the heater and an exhaust vent on the opposite wall.

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.
