Frequently Asked Questions

How does a steam sauna differ from a traditional or infrared sauna?

Steam saunas operate using a steam generator that produces moist heat—typically raising humidity levels to 100% while maintaining temperatures between 110°F and 120°F. This differs from dry saunas, which use hot air, and infrared saunas, which use light to warm the body. Steam is more hydrating and gentler on the skin and lungs, making it especially beneficial for respiratory health, skin cleansing, and sinus relief. Many clients in Orange County choose steam saunas as a complement to dry or infrared heat for a complete wellness experience.

What kind of maintenance do steam saunas require?

Steam saunas require a bit more upkeep than dry saunas due to the moisture and mineral buildup. However, with the right care, they are easy to maintain:

* Wipe down benches and walls after each use

Use soft or filtered water in your steam generator to prevent scaling

* Drain and clean the generator monthly

* Keep ventilation flowing to avoid mold buildup

Our team will show you how to maintain your system during installation so you can enjoy it with confidence.

Can I install a steam sauna in my home, or is it only for spas and gyms?

Steam saunas are increasingly popular in residential homes—especially in master bathrooms, converted basements, spa rooms, or home gyms. We’ve installed custom steam units in properties from Irvine to Dana Point, and even in compact spaces like garage wellness nooks and guest room additions. With vapor-sealed construction, drain planning, and moisture-resistant finishes, we make sure your steam sauna integrates seamlessly into your home while meeting safety and building standards.

What size steam generator do I need for my space?

The steam generator must match the volume of your sauna and the materials inside it. Rooms with glass or stone surfaces may require more powerful units to compensate for heat loss. As part of your consultation, we calculate the ideal kW output for your space and recommend reliable generator brands based on efficiency, warranty, and performance.

We also offer digital control panels, so you can easily schedule pre-heats, adjust temperature and duration, or set aromatherapy cycles—all from inside or outside the sauna.

What materials can be used for the walls in a steam sauna?

Unlike traditional saunas that rely on dry heat, steam saunas require moisture-resistant construction from top to bottom. Standard wood interiors—like cedar or hemlock—must be specially treated or installed with vapor-sealed backers to prevent warping and mold. In many residential steam sauna builds, we recommend a combination of:

Tile or natural stone finishes (granite, marble, or porcelain) for long-lasting moisture protection

Concrete backer boards (like HardieBacker or Durock) behind any wall finish to resist humidity

Thermally modified wood on ceilings or benches for spa aesthetics with better water resilience

Anti-drip ceiling designs to prevent condensation from falling onto occupants

We custom-build each steam sauna based on your space and preferences, ensuring the materials are safe, effective, and code-compliant for prolonged steam exposure. Whether you're building into a bathroom, garage, or spare room, our team will guide you through the best material options for durability and visual appeal
