Indoor Saunas

Turn Your San Francisco Home Into a Personal Oasis

Imagine enjoying the calm and rejuvenation of a luxury spa—right inside your own home. At San Francisco Custom Saunas, we bring this vision to life by designing and building fully customized indoor saunas that integrate seamlessly with your living space. Whether it’s tucked into a master bath in Noe Valley, a converted room in the Mission, or a basement adjacent to a gym, we turn underutilized areas into cozy wellness retreats. Every project is uniquely crafted, with attention to comfort, long-term performance, and health benefits tailored to Bay Area living.

What You’ll Get With a Custom Indoor Sauna

Each installation is uniquely planned—not a generic kit. We begin with spatial design and acoustic/ventilation considerations, then proceed to expert installation. We work with premium woods such as cedar, hemlock, and spruce, matched with your choice of heater: electric, steam, infrared, or hybrid.

Want to elevate the experience? Add enhancements like LED mood or chromotherapy lighting, integrated sound systems, or ergonomically contoured benches. Each feature is blended into the design so it feels built-in—not afterthought.

Frequently Asked Questions

How long does it take to install an indoor sauna in San Francisco?

Most Bay Area indoor sauna builds are wrapped up in about one to two weeks once materials arrive. Our process starts with a consultation and site evaluation, followed by clear drawings and logistics planning. We coordinate with electricians and carpenters who know local HOA rules, condo layouts, and San Francisco permitting quirks. Installations in city apartments often mean working within elevators and narrow hallways, while suburban homes in the East Bay give us more flexibility. Once construction is complete, we provide a full walk-through, operation demo, and maintenance guide.

Do indoor saunas need special electrical or ventilation systems?

Yes. Safe installation requires proper setup. Electric and infrared saunas typically need a dedicated circuit with GFCI protection. We’ll coordinate with your licensed San Francisco electrician—or connect you with a trusted partner—to ensure wiring meets all local codes.

Ventilation is equally important to control humidity and promote drying between uses. Our team accounts for airflow and moisture management during the planning phase so your sauna performs efficiently without affecting the rest of your home.

Where’s the best spot in a San Francisco home for an indoor sauna?

Popular SF placements include converted master baths in Noe Valley, garage studios in Oakland, and spare bedrooms in Berkeley and Daly City. We carefully plan airflow and insulation so your sauna works year-round, whether you live near the fog of the Sunset District or the drier climates east of the Bay.

What size should I expect for a custom indoor sauna?

Typical San Francisco footprints include 5′×6′ rooms for solo users, 6′×7′ for two or three people, and 7′×8′ builds for families or friends. We generally recommend 7′–7′6″ ceilings for consistent heat; higher ceilings require special air movement solutions. We also design for unusual layouts, like corner units or narrow spare rooms, so your sauna fits perfectly.

Can I put a custom sauna in my basement?

Absolutely. Basements are one of the most popular choices for sauna installations in the Bay Area. They’re naturally cooler, quiet, and often underutilized. We’ve converted basements in homes from Pacific Heights to Daly City into beautiful private spas. Whether you want a stand-alone sauna room or one incorporated into a gym or media space, we ensure proper insulation, ventilation, and heater placement. All heating types—electric, infrared, and steam—can be customized for basements.
