FAQs
Why choose Thermo Spruce or Thermo Aspen over traditional cedar?
Our saunas are crafted from thermally modified spruce and aspen, responsibly sourced from Estonia. Unlike traditional cedar, these woods are refined through a heat-and-steam process. No chemicals, no toxins. The result: beautiful, clean wood that resists warping, mold, and decay. It's the gold standard for high-heat environments, engineered for longevity and wellness.
How energy-efficient are the saunas, and what kind of power do they require?
Affetto saunas are designed for conscious luxury. Precision heaters with digital controls offer efficient performance without compromising on warmth. Most models require a 240V dedicated line. For safety and optimal performance, we recommend professional installation by a certified electrician.
Can I assemble the sauna myself, or will I need professional help?
Our saunas arrive in pre-assembled panels, designed for an intuitive build. With two people, setup can often be completed in a single day. For a seamless, stress-free experience, consider hiring a contractor familiar with modular or prefab structures.
Can I control the sauna remotely?
Yes. Select models are equipped with the UKU Wi-Fi controller, allowing you to preheat and manage your sauna from your smartphone. Perfect for establishing daily rituals with ease and consistency.
What foundation do I need for my sauna?
We recommend a solid, level surface such as concrete, pavers, or a pressure-treated deck. A stable foundation ensures proper drainage, structural longevity, and peak performance over time. Should you have any questions, please contact our team at inquiries@affetto.life

CARE INSTRUCTIONS
Affetto saunas are designed to age gracefully with minimal upkeep. To preserve their natural beauty and function:
- Regular Cleaning: Wipe down benches, walls, and flooring with a soft cloth and a natural, non-toxic sauna cleaner after each session. This removes sweat and maintains hygiene.
- Ventilation: After use, leave the door slightly open to promote airflow and prevent excess moisture buildup.
- Avoid Harsh Chemicals: Our thermally modified wood is naturally antimicrobial skip abrasive cleaners or bleach-based solutions.
Optional Long-Term Care:
- Sauna Wax or Oil: Apply a thin layer of sauna-specific wood wax or natural oil (e.g. paraffin oil or beeswax-based sauna care products) to benches and backrests a few times a year. This protects the wood, enhances color, and makes it easier to clean over time.
- Exterior Protection: For outdoor saunas, periodically check the roof and apply weather-protectant oil or sealant to external wood if desired. Your included rain jacket offers day-to-day protection from the elements.
Always test any treatment on a small area first, and refer to your sauna’s manual for approved care products.
