Indoor Saunas

Indoor saunas can be installed in many parts of your home—each with its own benefits. Finished basements are great for larger units and better temperature control, while master bathrooms offer convenience and luxury. We’ve also installed saunas in spare bedrooms, walk-in closets, ADUs, and home gyms. We’ll help assess your space, ventilation, and layout to recommend the ideal location for comfort and performance.

Yes, proper electrical and ventilation planning is essential. Most electric and infrared saunas require dedicated circuits and GFCI outlets. We can work with your licensed electrician or recommend one to make sure all systems are safe and compliant. For ventilation, we design with airflow in mind to protect your walls and ensure the sauna dries properly between uses. Our team handles all these details during the planning phase.

Timelines vary by scope, but most indoor sauna installations are completed in 3–10 days after materials arrive. We start with a consultation, create a detailed 3D design, and then coordinate all materials and labor. Our team works efficiently and respectfully within your home. We also provide a full walkthrough after installation to ensure you’re comfortable using and maintaining your new sauna from day one.

Yes—basements are among the most popular locations for indoor sauna installations. Their naturally cooler temperatures, privacy, and unused space make them ideal for creating a relaxing retreat. At Orange County Custom Saunas, we’ve installed basement saunas in homes throughout Irvine, Mission Viejo, and Costa Mesa, transforming underutilized rooms into wellness spaces tailored for daily use.

Basement saunas can be designed as standalone wellness rooms or integrated into existing home gyms, bathrooms, or finished entertainment areas. We ensure each project includes proper ventilation, insulation, and heater placement for safe, efficient use. Depending on your layout, we can install electric, infrared, or even steam systems—all customized to suit your preferences and available space.

Beyond basements, other popular indoor sauna locations include master bathroom suites in Newport Beach, converted closets in Laguna Niguel, and garage studios in Santa Ana. We’ll help you explore all your options to find the most comfortable and functional location in your home.

Custom indoor saunas can be designed to fit almost any space, but there are some general guidelines that help ensure comfort, performance, and safety. At Orange County Custom Saunas, we design indoor units ranging from compact 4’ x 4’ one-person models to larger 6’ x 8’ or 8’ x 10’ multi-person saunas.

Minimum height requirements are just as important as floor space. The standard sauna ceiling height is around 7 feet, which helps contain heat efficiently while providing enough headroom for users. We recommend avoiding heights above 8 feet, as taller ceilings make it harder to maintain even heat distribution—especially with traditional electric or wood-fired heaters.

Popular layout configurations include:

4’ x 6’ for 1–2 people with a corner bench

6’ x 8’ for 3–4 people with tiered seating

5’ x 7’ for small families or dual-purpose home gyms

If you’re working with a unique space—like an angled ceiling, alcove, or converted walk-in closet—we’ll create a fully customized layout that maximizes every inch without compromising safety or experience. We’ve successfully installed indoor saunas in homes across Huntington Beach, Tustin, and Aliso Viejo, adapting to everything from low-clearance areas to long, narrow spaces.

Still unsure about sizing? During your consultation, we’ll assess your space and recommend ideal dimensions based on your goals and daily usage habits.
