Frequently Asked Questions

How do I know which steam generator I need?

The right generator depends on the size of your sauna and the materials you select. Stone, glass, and tile retain heat differently than wood, requiring more powerful equipment. During your consultation, we’ll take exact measurements and factor in your finishes to recommend the ideal system. We work with reliable brands that feature digital controls, pre-heat timers, and aromatherapy options, giving you a personalized spa experience at home.

Which is better—steam or dry sauna?

It depends on your goals. Steam saunas provide a humid, spa-like atmosphere that’s gentle, hydrating, and supportive of respiratory wellness. Dry saunas reach higher temperatures with low humidity, encouraging deeper sweating and muscle recovery. Many San Francisco clients choose steam for relaxation and skincare, while others prefer dry heat for athletic recovery. Some homeowners even install both to enjoy the benefits of each.

How is a steam sauna different from infrared or dry heat systems?

Steam saunas use a generator to fill the space with warm vapor, creating nearly 100% humidity at a moderate 110°F–120°F. Dry saunas** operate hotter (160°F–190°F) with minimal humidity, while infrared saunas heat your body directly at lower air temperatures. Steam saunas stand out for their skin-hydrating and respiratory benefits, making them a popular choice for Bay Area homeowners who want a calming spa retreat at home.

Can I add a steam sauna to my San Francisco home, or are they only for spas?

Absolutely—you don’t need to go to a spa. Steam saunas can be built into master bathrooms, basements, home gyms, or even compact condo spaces. With proper vapor sealing, waterproofing, and drainage, they can be adapted to almost any layout. Our team ensures your sauna design meets local San Francisco building codes while blending seamlessly into your home’s aesthetic—whether you live in a historic Victorian in the Mission District or a modern condo in SoMa.

What materials are best for steam sauna walls and ceilings?

Moisture resistance is key. Tile, porcelain, marble, and granite are top choices for walls since they handle steam well and provide a refined look. Behind the surfaces, we recommend cement backer boards like HardieBacker or Durock to prevent mold and warping. Ceilings are sloped or drip-resistant to stop condensation from falling directly on users. For benches and accents, heat-treated woods like cedar or hemlock add comfort and warmth without absorbing too much moisture.

How much upkeep does a steam sauna need?

Maintenance is simple with the right care. Wipe down walls and benches after each session to prevent mildew. Use filtered or softened water to limit scale buildup in the generator, which should be drained and cleaned monthly. Ventilation also helps manage humidity and air quality. When we install your sauna, we provide a full maintenance guide so your steam sauna stays clean, safe, and efficient for years of use.
